Introduction。
Physics experiments are an essential part of the learning process for students studying the subject. They allow students to apply theoretical knowledge to practical situations, enhancing their understanding and retention of the material. In this article, we will explore the importance of physics experiments and provide a templatefor writing a CET-4 essay on the topic.Importance of Physics Experiments。
Physics experiments play a crucial role in the learning process for several reasons. Firstly, they provide students with hands-on experience, allowing them to observe and interact with physical phenomena directly. This direct experience helps to solidify theoretical concepts and makesthe subject matter more tangible and relatable.Additionally, physics experiments encourage critical thinking and problem-solving skills. Students mustcarefully plan and execute experiments, analyze data, and draw conclusions based on their findings. This process fosters a deeper understanding of the scientific method and helps students develop essential skills that are applicable across various disciplines.Furthermore, physics experiments can spark curiosity and interest in the subject. When students witness the practical applications of physics principles, they are more likely to become engaged and motivated to learn more. This can lead to a greater appreciation for the subject and potentially inspire students to pursue further studies or careers in physics-related fields.Template for Writing a CET-4 Essay on Physics Experiments。

When has was just 18 years o ld, a terrible event occurred: his right leg had to be cut off because of cancer. Such an experience would have destroyed a weaker person-but Terry Fox was a fighter. He refused to give up. Instead, while he was recovering from the operation, an idea slowly formed in his mind. He decided he would run acro ss Canada, in order to raise money for cancer research.Slowly and carefully, he began to train. Every step was extremely painful, but he insisted on increa sing the distance covered day by day. Sixteen months later, in the spring of 1980, he was ready for the long journey across Canada-his Marathon of Hope. It was a time of inspiration and heart-breaking e motion(感情). Through television, every home saw his particular way of running, a kind of half-hop a nd half-run. Thousands of people lined the route(路线)to encourage him and to wish him well. They also gave money to fight cancer. Then, on September 1st, 1980, after 143 days and more than 5,000 kil ometers completed, everything came to an end. Terry had to stop.

It also lifted its travel warning against the city-the last in the worl d. Beijing was put on the WHO‟s travel warning list on April 23.The announcement came after the cases in Beijing‟s hospitals fell to 46-well below the WHO cut-off point of 60. Beijing had recorded a total of 2,521 cases of SARS and 192 deaths by June 26.“Today‟s development is a milestone in the fight against SARS, not only in China but also around t he world. From today, the WHO has no more warnings against any places around the world, ”said Shig eru Omi, a WHO official.Just one month ago, going out without a mask(口罩)would have been thought of as daring in the capital city of 13 million people.At the peak(高峰)of the SARS outbreak, people from Beijing were the “most unwelcome people”i n the country. They were forced to cancel or put off almost all their travel plans, as most provinces and cities put a two-week quarantine(隔离期)on travelers from Beijing.With the WHO‟s announcement, life in China has returned to normal. All students in Beijing will r eturn to school after more than two months of staying at home. And traveling has again become a big plan for the summer holiday.However, medical experts have warned against any relaxation(放松)of SARS prevention and contr ol measures after the lifting of the WHO travel warning.55.

Beijing was the last city in the world to be removed from WHO‟s list of SARS-infected areas.B. At the peak of the SARS outbreak, Beijing‟s tourism was not greatly affected.C.

WHO had no more travel warnings against any places around the world by the beginning of Ju ne.(C)The Amish are often called the “Plain People. ”Their homes have no pictures on the walls, and no soft. comfortable furniture. The men wear dark trousers with white or blue shirts, and the women wear long dresses in dark colors. They ride in carriages pulled by horses.The Amish have a saying: “The old way is the best way. ”Although the Amish accept some new i deas -they use new medicines, for example-their way of life has not changed much in 300 years. The y do not use electric lights, telephones or TVs.Almost all Amish live on farms. They do not use modern machinery, yet their farms are successful because the Amish work hard and take good care of their land and animals. Their farms are always s mall. The Amish think it is wrong to have more land or more money than they need to live upon. A f ew years ago some Amish farmers discovered oil on their land. They immediately sold their land and m oved away, without telling anyone about the oil.The Amish will not buy insurance (保险)of any kind. When there is trouble, they help one anoth er. If an Amish farmer gets sick, friends and neighbors will milk his cows and plant his fields. If a hou se burns down, as many as 200 men will come and build a new house in one day.People are curious about the lives of the Amish. Every year thousands of people visit the part of P ennsylvania where most Amish live. Usually the Amish are not happy about the visitors, but they stand them. Perhaps the Amish understand that the visitors want to experience, at least for a few days, the qu ieter, simpler Amish way of life.64. The Amish are called the “Plain People”because they _______.A. live on plainsB. live a simple lifeC. do not like new ideasD. do not care about their clothes65. Some Amish farmers left their land after discovering oil on it because they _______.A. didn‟t need oil in their lifeB. were afraid of getting into troubleC. found the land not suitable for farming any moreD. didn‟t want to have more money than they needed66. From the passage we know that the Amish people ________.A. want to be separated from one anotherB. used to take no medicines when they got illC. believe in what they have been doing for 300 yearsD. keep small farms because they are easier to manage67. It can be inferred from the passage that _______.A. people wonder at the Amish way of lifeB. the Amish people are born to stand othersC. the Amish way of life is considered to be that best for AmericansD. the coming of visitors greatly improves the life of the Amish peopleDToday‟s teen consumer market is the most profitable (有利润的)it has ever been. Even though 65% of teens claim that they depend on themselves for their fashion ideas, it is innovative (创新的)enoug h to drive fashion trends, according to a recent study by a marketing firm. Marketers recognize this fact and often use elements of youth culture to promote (宣传)their products. Perhaps one of the best exa mples is their use of hip-hop culture. It is reported that hip-hop fashion alone generates $ 750 millio n to $ 1 billion annually (every year). Sales of rap music and videos each exceed that amount.Rap‟s rise and sustained (继续,维持)global popularity is a good illustration (说明)of how infl uential youth culture is on youth attitudes and behavior. Remember when Madonna hit the charts with h er bra in full view while singing about “virginity”? Soon after that, adolescent (青少年的)girls around the world began wearing their underwear outside their clothes.Fashion designer Tommy Hilfiger was fully aware of the power of youth culture. He marketed his brand by giving clothes to famous MTV stars and featuring teen stars in his print ads. Picking up on tee ns‟ interest in computer games, Hilfiger sponsored (赞助)a Nintendo competition and installed Nintend o terminals in his stores. The payoff? Teens rated Hilfiger jeans as their number one brand in a survey in 2000.68. What is the best title for this passage?A. The Importance of Marketing.B. The Success of Tommy Hilfiger.C. The Power of Youth Culture.D. The Popularity of Hip-hop Fashion.69. How much money do sales of rap music and videos together make each year?A. More than $ 1 billion.B. Less than $ 500 million.C. Between $ 750 million and $ 1 billion.D. Between $ 500 million and $ 750 million.70. According to the passage, which of the following statements is TRUE?A. The purchasing power of teenagers has been decreasing over the years.B. Many teenagers make a lot of profits in the fashion market today.C. Madonna led the fashion of wearing underwear outside clothes.D. Marketers recognize youth culture as a part of hip-hop culture.71. It can be inferred from the passage that Hilfiger ________.A. believed that MTV stars could drive fashion trends among teensB. sold Nintendo terminals together with te ens‟ clothes in his storesC. sponsored a Nintendo competition out of his own interest in computer gamesD. was rated by teens and adults as the best designer of jeans around the world in 2000EExtract 1A rich and varied programme of entertainment is available in Cambridge, provided by the City Cou ncil, University and college societies and private promoters.

The Cambridgeshires(剑桥郡)material includes household goods and personal ornaments (装饰品)from excavations (挖掘)and chance finds.Upstairs, the Ethnology collection has a wealth of material from Africa, the Americas, Asia and the Pacific. It includes complete sets of clothing, tools, weapons, ornaments and ritual objects, and many of the manufacturing processes used by primitive (原始的)people are explained. The collections are open 14:00 to 16:00 Monday to Saturday, but are undergoing reorganization.Extract 3GREAT ST. MARY‟S CHURCH Almost all the present church dates from the late 15 th century (r eplacing an earlier church), and it has the spaciousness typical of the perpendicular(垂直的)style. The tower (which can be ascended )was not finished until the 17th century. The church was used a great deal for University meetings and ceremonies, and it retains its status as the University Church. The Univ ersity sermons, on Sunday evenings during term, bring notable people of all denominations (教派)to s peak on important topics.Extract 4Recent city developments include areas of new housing at Arbury, King‟s Hedges and Cherry Hinto n, with shops, schools, public houses and libraries, and the replacing of some nineteenth-century housin g. A subtle redevelopmen t in Newtown, near Lensfield road, was recently“highly commended”by the Dep artment of the Environment as an example of new housing in an old setting.

How I wished I had some with me! “William, the monkeys are taking long to come out today. Wait till they smell the peanuts.” I knew he was lost in one of his memo ries again. I remembered the stories he told me of how he fed the monkeys when he was a kid. Then, he saw the goldfish! He acted as if he was seeing them for the first time.Poor Grandpa! He fell ill with Alzheimer’s disease last year. The doctor said it c ould destroy a person’s memory. The patient might also not be able to make reasonable judgments. The sad part was that it was a lifelong disease. But when my parents invited him to stay with us, he refused and said he liked living alone. One day, he forgot to turn off the fire after cooking porridge. Luckily, one of the neighbors came to help him before the fire could spread.It was then that my parents brought Grandpa to live with us. Often, he would forget my name and ask me who I was and what I was doing in his house. Each time I would answer softly, “It’s me, Ray, Grandpa!” Even if he had forgotten who I was, he would always be my beloved grandfather.1. What did Grandpa want to do in the park?A. Eat peanuts.B. Smell flowers.C. Feed monkeys.D. Tell stories.2. What would happen to Grandpa according to the doctor?A. His brain wouldn’t need examinations.B. His memory could get better.C. He might not judge things correctly.D. He had to live by himself.3. What does the underlined word “destroy”mean in Chinese?A. 增强B. 改善C. 放弃D. 破坏4. Why did the writer’s parents bring Grandpa to live with them?A. To make sure of his safety.B. To help him remember their names.C. To answer his questions in time.D. To get his help with the housework.5. Which of the following best describes the writer?A. Smart.B. Caring.C. Honest.D. Brave.BWhile the start of a new school year is always exciting, this year was even more so for some students at White Cloud Primary School. They became the world's first kids to be“taught”by an electronic teacher. This electronic teacher is not a human-like robot walking around the classroom. Instead, he is a computer-created head that appears, when needed, on students' computers or phone screens. His name is Bill.Created by technology company Smart Machines. Bill is able to show human-like behavior. He is designed to teach a special program about environmental-friendly power created by the sun and wind. This program, started in 2005, used to be taught by human teachers.Just like human teachers, Bill is able to immediately respond to the students' questions and opinions about the topic. Thanks to computer cameras, he is also able to see and react to students' physical actions. For example, if a student smiles at Bill, he responds by smiling back. This two-way exchange helps get the students' attention.More importantly, it allows the program developers to improve Bill's behavior and knowledge base when needed. The program has been a great success, according to Smart Machines s pokesman Robert Frost. Frost says,“What is interesting to me is the children's reaction to Bill. He really captures their attention.” Frost thinks kids don't find the experience of being taught by smart machines as strange as older people because they have grown up in a time of computers and smart phones.It is doubtful, however, that human educators will lose their jobs to Bill any time soon. For one, this talking head's knowledge base is not large. More importantly, even the smartest computer programs can't guess and react to all the unexpected situations that educators face daily. Bill's future might be as a“personal tutor”, providingkids with one-on-one help for different subjects and topics.6.What is Bill?A.A human-like robot.B.A kind of computer game.C.A computer recording tool.D.A computer-created talking head.7.How does the two-way exchange help the program developers?A.It lets them correct students' mistakes.B.It allows Bill to respond more quickly.C.It helps them know how to improve Bill.D.It helps them study students' body language.8.The underlined word “they” in Paragraph 4 refers to _______________ .A.kidsB.older peopleC.smart machinesD.program developers9.What is Bill NOT good at doing?A.Attracting students' attention.B.Understanding body language.C.Responding to students' questions.D.Dealing with unexpected situations.10.How might Bill be used in the future according to the last paragraph?A.To work as human classroom teachers.B.To encourage students' interest in computers.C.To give students personal help with different subjects.D.To watch over the behavior of the students in the classroom.CPeople in Western countries are eating less meat these days, whether for their health or because they want to protect animals. But now they have another reason.Eating less meat can help to prevent climate change, according to a recent study published in Nature.Raising livestock is bad for the environment. When animals like cows digest(消化) food, their stomachs make greenhouse gases, which are a major cause of global warming. Seventeen percent of greenhouse gas emissions(排泄物)come from livestock farming, The New York Times reported.In addition, to raise these livestock, people have to cut down forests and turn them into farms. Forests play key role in fighting global warming because they absorb greenhouse gases.Eating less meat according to certain guidelines could cut global food-related emissions by nearly a third by 2050, the study found. Maintaining a vegetarian diet in the long term could bring down emissions by 63 percent. But eating less meat won’t be easy. According to the study, people in Western countries will need to eat90 percent less meat than they do now in order to have an impact on our climate. Scientists are now trying to find new foods to replace meat.Some say that insects could help. A 2013UN report said that eating insects is healthier and better for the environment. They produce 75 percent less greenhouse gases than livestock.Some experts are creating lab-grown meat. They make meat in a lab using livestock cells. In March, US company JUST said people in the US might be able to buy its lab-grown meat by the end of this year.11.According to the story, eating less meat can help us _________.a. stay healthy.b. reduce waste,c. protect animals,d. slow down climate changeA.a;b;cB. b;c;dC. a;b;dD.a;c;d12.What do the underlined words “livestock” in the third paragraph mean?A. 牲畜B. 植被C. 农场D. 飞禽13.How much less meat should people eat to influence the climate?A. 63percentB.70percentC. 75percentD. 90percent14.Eating less meat can help protect the environment because_________A. there will be less animal-related wasteB. less livestock means less greenhouse gas emissionsC. animals are an important part of the environmentD. people will plant more trees around their houses15.What’s the main idea of the story?A. Why Westerners eat less meat these daysB. What people will eat in the future?C. How eating less meat influences the environmentD. What the major cause of global warming is四.七选五阅读理解The world is getting bigger, or at least fatter. Recent studies show that more and more people are living an unhealthy life. 1.___________ Sofa potatoes are people who spend too much time in front of the TV and eat too much junk food. Now, there is also a new kind of people, namely the “mouse potato”. 2.___________ Why are we becoming potatoes?3.___________ We don′t have as much time to prepare and eat food as we used to. Fast food restaurants are everywhere and supermarket shelves are filled with ready-made or prepared dishes.4.___________ But they make it more difficult for us to control what we eat.5.___________ In this way, we will be healthier and have more energy to enjoy the good things in life. A healthy diet should give us the calories (卡路里) we need but not contain too much fat and sugar. A balanced diet with exercise is the recipe for a healthy life. And remember, it is better to eat a potato than to be one.A. Of course, not all of these are bad for us.B. We are becoming sofa potatoes.C. We can′t eat junk food.D. We should choose the delicious food.E. They sit in front of the computer all day and eat junk food.F. One reason is our modern way of life.G. To be healthy, we should make good choices about what we eat.五.书面表达假设你是珍妮,中考后你将参加赴英国的“名校之行”夏令营活动,请你根据以下表格提供的信息准备一篇在开营仪式上的自我介绍发言稿。

PhysicsTest Review for Units 1 - 4NameOne-Dimensional Motion, Vectors, Falling Bodies, Projectiles Trig Version Test Objectives and Study HintsMultiple ChoiceCovers all topics, but stresses projectile motion concepts.Be prepared to make or interpret graphs of objects in ANY of the motions we have studied, including falling objects and projectile motion.Be prepared for questions testing your understanding of the independence of horizontal and vertical motion; review concepts behind class demos such as the simultaneous velocities apparatus, ballistic car, monkey and hunter.TO PREPARE:Read all of your notes carefully.Review the readings and worksheets on motion graphs and projectile motion.Study the multiple choice questions on the “measurement and motion” and “vectors/falling bodies” quizzes. Be sure you know the concept each questions deals with.Do the accompanying concepts check and concept review questions.ProblemsBe prepared for problems involving projectile motion, falling bodies, and a combination of both. For example, some falling body problems can become simple projectile motion problems testing your understanding of the independence of horizontal and vertical motion.EXAMPLE: Review Problem #9Be prepared for a multiple-step vector problem. For example, you could be given two acceleration vectors along with a time and asked to calculate the final velocity of an object that started from rest. You would add the accelerations with vector math and then use v=v+at.f iEXAMPLE: Review Problem #10Be prepared for a multiple-step ground-based problem. For example, sometimes the answer to one "part" of a problem becomes a given in the second "part" — you may be given information that will not directly lead to the answer, but can be used to generate another given that leads to the answer. Or, you may need to split a problem into two parts because the acceleration varies.EXAMPLE: Review Problem #12TO PREPARE:Rework the problems on the “measurement and motion” and “vectors/falling bodies” quizzes. Rework several different types of projectile motion problem - there are about five variants.Up over level ground; dropped from height; shot angled downward from height; shot upward and land on cliff or land in valley.Do the accompanying review problems.Units 1-4 Test Review, Trig Version Page 1 of 6Practice Problems(answers are in italics at the right margin; some of these old questions were written with 2 significant figures - the test will be written with 3 sig figs throughout)1.Phyllis Physics set a course of 25.0E East of South in her airplane and a speed of 100 m/s.

All objects fall with the same acceleration rate (same rate of velocity change) inthe absence of air resistance. Even with air resistance, objects of the same size and shape can bepresumed to encounter about the same drag.Possible Misconceptions for W rong AnswersA:Mistaken belief that heavier objects fall faster than lighter ones.B or E:Possible mis-reading of question or answers.D:Mistaken belief that heavier objects fall faster than lighter ones, or misinterpretation of the effect of air resistance.14.The correct answer is D. A projectile will follow a parabolic path, and is immediately acted upon by gravityupon release.Possible Misconceptions for W rong AnswersA or B:Mistaken belief that mass makes things stop, or failure to realize that a projectile has same initial velocity as the projector.C:Failure to realize that the vertical velocity of a projectile in free-fall will change.E or F:Failure to realize that a projectile is affected by gravity immediately upon release, or mistaken belief that a projected objectreceives some sort of “impetus” that slowly disappears.15.The correct answer is A. The horizontal velocity of a projectile is constant (its changing vertical motion willnot directly affect its horizontal motion) and all objects fall with the same acceleration rate in the absence of air resistance. Even with air resistance, objects of the same size and shape can be presumed to encounter about the same drag.Possible Misconceptions for W rong AnswersB:Mistaken belief that heavier objects fall faster than lighter ones, or that lighter projectiles are not affected as quickly by gravity.C Mistaken belief that heavier projectiles retain their horizontal motion better than lighter ones. Possible mis-reading of questionand answers.D:Mistaken belief that heavier objects fall faster than lighter ones, or that lighter projectiles are not affected as quickly by gravity.Also possible that the effect of air resistance was misinterpreted.E:Mistaken belief that heavier projectiles retain their horizontal motion better than lighter ones. Possible mis-reading of question and answers, or that the effect of air resistance was misinterpreted.16.The correct answer is E. The bottom block retains a constant speed of 4 ticks per 0.2 s time interval. Thetop block is accelerating, as shown by an increase in speed (an increase in the “ticks” or distance traveled during each time interval). The top block traveled 4 ticks during the 3 to 4 time interval, so its averagespeed during that interval was the same as the the steady speed of the bottom block. Thus, it was moving at that speed sometime during the 3 to 4 interval.Possible Misconceptions for W rong AnswersA:Failure to properly distinguish between velocity and acceleration, or failure to note that distance/time indicates average speed.B orC or D:Failure to properly distinguish between displacement and velocity. The block’s position alone does not indicate itsspeed. Its speed is found by examining the change in position over a time interval.17.The correct answer is D. Both blocks are showing a steady change in distance over time, or a steadyspeed. (Block A has a speed of 4 ticks per time interval; block B has a speed of 6 ticks per time interval.) An object with a constant velocity is not accelerating.Possible Misconceptions for W rong AnswersA:Failure to note that distance/time indicates average speed.B or C:Failure to properly distinguish between velocity and acceleration, or failure to note that distance/time indicates averagespeed.18.The correct answer is D. The object is a projectile in free-fall because it has a steady horizontal velocityand a changing vertical velocity. Its initial vertical velocity is positive, so it was projected upward. Its final vertical velocity is negative, so it ended its motion while moving downward. Its final downward speed issmaller than its initial upward speed, so it was caught before it had reached its original level (at whichpoint it would have regained its original speed).Graphs Corresponding to the W rong AnswersA.
