Level4 Unit2 Part1 Listening - Extinction Events 1The Earth was formed about 4.6 billion years ago.The first life appeared about a billion years later.The first plants didn't appear until around 2 billion years ago.Until about 580 million years ago, life forms were small and microscopic. Since that time, life has evolved into many different types, or species. However, scientists estimate that more than 99% of them are now extinct.There have been several extinction events in the history of the Earth.In an extinction event many life forms, or species of life, die out.The causes of mass extinction events are unsolved mysteries.These events are not predictable and can happen at any time.Scientists think that some of them were started by asteroid impacts or volcanic eruptions.Events like these can change the global conditions that life depends on.One major extinction event happened about 66 million years ago.That event may have been started by a large asteroid that hit the Earth.As a result, the dinosaurs and about half of all species on the planet died out. When the asteroid hit the earth, it started a chain of events.A chain of events is a series of events linked together, like a chain.This particular chain of events happened over a period of months and years.When the asteroid hit the Earth, it caused a huge cloud of dust to enter the atmosphere.This cloud of dust blocked the sun and darkened the Earth for many months. Without enough sunlight, plants and plant-eating animals quickly died.With the deaths of so many plants and animals, the food chain collapsed.This led to the deaths of many more species.Mass extinction events have played an important part in the evolution of life.In fact, some extinction events have helped to accelerate evolution.For example, some mammals lived through the age of the dinosaurs, but they couldn't compete.When the dinosaurs were removed, the mammals were able to compete more successfully.Once they could compete, mammals evolved to a higher state.Without extinction events, perhaps we wouldn't be here today.Level4 Unit2 Part1 Listening - Extinction Events 2Scientists estimate that there have been at least 5 mass extinctions in the last 540 million years.They also believe that we have entered a new extinction event.Species are becoming extinct at a much faster rate than before.Instead of asteroids or volcanic eruptions, the current event is the result of human activities.Human activities, for example, have led to global warming.Global warming is the result of an increase in carbon gases in our atmosphere.These gases trap heat from the sun, so the Earth is getting warmer.As a result, sea levels are rising and weather patterns are changing.In addition, we humans are destroying the habitats of many plants and animals.Cutting down forests and polluting rivers destroys the habitats of many forms of life. There is no longer any doubt that this is happeningSpecies of life are disappearing at an increasing rate.Global temperatures are rising and weather patterns are changing.Scientists are warning us that fast action is necessary to save our future.If we don't act, we may go the way of the dinosaurs.(This new extinction event is caused by humans.)Level4 Unit2 Part1 Vocabulary - Body SystemsThe body's circulatory system includes the heart and blood vessels.The heart pumps blood to all parts of the body through a network of arteries and veins.The digestive system breaks down and absorbs food into the body.It supplies the energy that the body needs for growth and repair.After digestion, excess food is turned into waste and eliminated from the body.The nervous system includes the brain, spinal cord and nerves.This is your body's control system.It controls your muscles and organs, including your circulatory and digestive systems.The respiratory system includes the nose and lungs.It brings air and oxygen into the body and removes carbon dioxide.The lungs are where oxygen enters the bloodstream and carbon dioxide is removed.The immune system protects the body against infections and diseases.Sneezing and fever are examples of how the immune system works.If an infection invades the body, the immune system attacks it.(The blood vessels that carry oxygen-rich blood from the heart are called arteries.)(The digestive system is where food is broken down and absorbed into the body.)(The nervous system regulates your heartbeat and digestion.)Level4 Unit2 Part1 Vocabulary - Great DiscoveriesThe controlled use of fire allowed people to cook food and survive in the colder climates.Fire provided light so that people could work and socialize for longer hours.With the invention of agriculture, people could grow food and settle into communities.By growing food, people could spend less time hunting and more time for other things such as art.The domestication of animals allowed people to raise and use animals for food and work.By raising herds of animals such as sheep, humans had a regular supply of meat and clothing.The strength of animals such as horses and oxen was used for work and transportation.The development of tools and machines has resulted in more efficient manufacturing and construction.With better tools and machines, work can be done with fewer people and at much lower costs.The development of science and engineering has improved many things, including communications.With an understanding of electricity, telephones and radios allow people to communicate over long distances.(Science and engineering have changed the way we communicate with each other.) (With the development of agriculture, people had more time for other activities.) (The use of machines has reduced the number of people needed to make things.)Level4 Unit2 Part1 Dialogue - Smartphone AddictionI took a vacation last night.What are you talking about?Where did you take your vacation?I didn't go anywhere.I just spent an evening without my smartphone.How was it?It was great.

It may be an apple, and it may be an orange.It’s got to be one or the other.It can’t be anything else.Now let’s look at it from the man’s point of view.From his point of view, the probabilities are different.From his point of view, the probability that he has an orange is 100% or 0%. That’s because he knows what he has.For him there is no uncertainty.If he has an orange, the probability is 100%.If he doesn’t have an orange, the probability is 0%.He either has it or he doesn’t.From our point of view, the probability that he has an orange is 50%.From his point of view, the probability that he has an orange is 100% or 0%. So the probability depends on your point of view.Level4 Unit2 Part2 Listening - Point of View 2People see things from different points of view.This often leads to arguments between people.Here are some examples.From this man’s point of view, he is relax ing.He needs to relax because he has been working too hard.He hasn’t been getting enough sleep.His wife sees things differently.She isn’t aware of how hard he has been working.From her point of view, he is doing nothing.However, she knows what needs to be done around the house.It isn’t fair that she has to work while he does nothing.When people see things from different points of view, they often come to different conclusions.These differences can cause real communication problems.Level4 Unit2 Part2 Vocabulary – DisastersEarthquakes are caused by forces deep within the Earth.When the earth shakes, buildings can collapse and people can be buried inside.An explosion is a rapid, violent release of energy.Explosions can be caused by chemical reactions, such as inside an engine.A spark can ignite a mixture of gases, and release energy for good or destructive purposes.Accidents are often caused by people doing foolish things or by not being careful.One major cause of accidents is driving too fast.Accidents with fire can be very serious, and can result in very painful injuries.Epidemics are the rapid spread of a disease, such as the flu or ebola.Throughout history, epidemics have killed millions of people.Storms are caused by changes in the atmosphere resulting in high winds and heavy rain.Thunderstorms are caused by electric charges in the atmosphere that produce lightning, which can cause forest fires.Some storms cause flooding, and major damage to homes and cities.Followers of the islam religion are called Muslims.These Muslims are praying inside a mosque.Muslims are called to prayer 5 times a day, beginning just before sunrise.Christianity is based on the teaching of Jesus Christ, who lived more than 2000 years ago.Christians believe that Jesus is the son of god.Christians often gather in churches or cathedrals to worship.Followers of Judaism are called Jews.These Jews are meeting inside the synagogue, which is a place of worship and study.Judaism was founded over 35 hundred years ago, in the middle east.Judaism is based on the teaching of Moses, who they believe is the most important prophet.Buddhism began in India and is based on the teachings of the Buddha.The religion is about 25 hundred years old.Some Buddhists practice a form of meditation in which they empty their minds of any thought.Hinduism is the world’s third most popular religion and is the main religion of India.Hinduism has no founder and is a mixture of many beliefs.Some Hindus believe in the cycle of birth, life, death and rebirth.Level4 Unit2 Part2 Vocabulary – ReligionsvFollowers of the islam religion are called Muslims.These Muslims are praying inside a Mosque.Muslims are called to prayer 5 times a day, beginning just before sunrise.Christianity is based on the teaching of Jesus Christ, who lived more than 2000 years ago.Christians believe that Jesus is the son of god.Christians often gather in churches or cathedrals to worship.Followers of Judaism are called Jews.These Jews are meeting inside a synagogue, which is a place of worship and study.

Alcatraz 1Alcatraz is a small island in San Francisco Bay, 1.5 miles from San Francisco.From Alcatraz, you can see the famous Golden Gate Bridge.Alcatraz is also famous and is now a major tourist attraction.Tourists can reach the island by boat from the city.Alcatraz has often appeared in movies, including "Escape from Alcatraz" which was made in 1979.One reason it’s famous is because it used to be a prison, a very special prison.It was designed for prisoners who were causing trouble in other prisons, such as trying to escape.It was a maximum security prison, so escape was almost impossible.The waters around it are cold, and only very strong swimmers can swim from the island to San Francisco.The first group of prisoners arrived in 1934.There were 137 prisoners, including bank robbers and murderers.They came by train from another prison in the state of Kansas.During that trip there was heavy security.The prisoners were under guard and handcuffed.Nobody wanted them to escape.Level4 Unit2 Part3 Listening - Alcatraz 2The prison was designed to hold up to 336 prisoners.However the average population was only about 270.Although there were several notorious inmates, such as Al Capone, most of the inmates were not well-known.Many had tried to escape from other prisons or were considered violent.If a man did not behave at another prison, he could be sent to Alcatraz.At Alcatraz there was just one inmate in each prison cell.Prison life at Alcatraz was highly structured and boring.It was designed to teach prisoners to follow rules.They had four rights: food, clothing, shelter, and medical care.Everything else was a privilege that had to be earned.Privileges included working, visits from family members, and access to the prison library.There were also activities such as painting and music.Once a prisoner showed that he could follow the rules, he could be transferred back to another prison to finish his sentence.Alcatraz was used as a prison for 29 years.During that time, no prisoner escaped successfully.There were 14 escape attempts, involving 36 prisoners.Twenty-three were caught alive, and six were shot and killed.2 men tried to escape twice.2 drowned and 5 were listed as missing and presumed drowned.The most violent escape attempt occurred on May 2nd, 1946 when 6 prisoners tried to escape.That event is called the "Battle of Alcatraz."While it was in use, Alcatraz held some of the most notorious criminals in American history, such as Al Capone.Al Capone was a crime boss who built his career in Chicago.The prison was finally closed in 1963.It was closed because it was too expensive to operate.(No prisoner ever escaped from Alcatraz.)Level4 Unit2 Part3 Vocabulary - Graphs & ChartsA bar graph uses rectangular bars of different lengths to show and compare data.The lengths of the bars are proportional to the values they represent.The bars can be vertical, up and down, or horizontal.A circle graph, often called a pie graph, is shaped like a circle.It is divided into segments that look like pieces of a pie.Percentages are used to compare the segments, which are ordered from biggest to smallest.Line graphs are used to show the relationship between two variables, such as time and distance.These variables are plotted on 2 axes, the X-axis and the Y-axis.The X-axis often shows time while the Y-axis shows how quantities, such as distance, temperature or profits change with time.A flowchart is a type of graph that shows how a process or project flows from start to finish.A flow chart consists of start points, inputs, outputs and decision points.An organizational chart, or org chart shows the structure of a company.It shows how people and departments within a company are connected.It defines the roles and responsibilities of people and departments within a company.(Line graphs are very good at showing how things change over time.)(A flowchart shows how a process or project flows from start to finish.)Level4 Unit2 Part3 Vocabulary -

Alcatraz 1Alcatraz is a small island in San Francisco Bay, 1.5 miles from San Francisco.From Alcatraz, you can see the famous Golden Gate Bridge.Alcatraz is also famous and is now a major tourist attraction.Tourists can reach the island by boat from the city.Alcatraz has often appeared in movies, including "Escape from Alcatraz" which was made in 1979.One reason it’s famous is because it used to be a prison, a very special prison.It was designed for prisoners who were causing trouble in other prisons, such as trying to escape.It was a maximum security prison, so escape was almost impossible.The waters around it are cold, and only very strong swimmers can swim from the island to San Francisco.The first group of prisoners arrived in 1934.There were 137 prisoners, including bank robbers and murderers.They came by train from another prison in the state of Kansas.During that trip there was heavy security.The prisoners were under guard and handcuffed.Nobody wanted them to escape.Level4 Unit2 Part3 Listening -

Atoms are the building blocks of matter.At the center of an atom is its nucleus which has a positive electric charge. Outside the nucleus are electrons which have a negative charge. Asteroids and comets are objects that obey our sun, but are smaller than planets.Asteroids that pass close to the Earth are called near-earth objects. The layer of gases just above the Earth’s surface is our atmosphere. The atmosphere is made of gases such as oxygen and nitrogen. Withoutan atmosphere there would be no life on Earth.If they collide with Earth they could cause an extinction event.A force can increase or decrease the speed of an object, and it can change the direction of motion. Theelectric force between the nucleus and the electrons holds the atom together.The two lines on the left intersect each other at a right angle which is90 degrees.The two lines on the right are parallel which means they never cross. The adjacent sides of a rectangle are perpendicular which means they meet a 90-degree angle.The opposite sides of a rectangle are equal and parallel which means they never cross.The area of a rectangle is the length times the width.A circle is a two dimensional figure with a radius and a circumference which is the distance around the circle.

Level3.Unit2 Part1作者：Ding MingListening: States of Matter物质状态Matter is made of atoms and molecules.Water, for example, is the H2O molecule.This means that a molecule of water has 3 atoms.这意味着水分子有3个原子。

A water molecule has two hydrogen atoms and one oxygen atom.Substances like sugar have many atoms in their molecules.A molecule of sugar has many atoms, including carbon, hydrogen and oxygen.------------------------------------------------------------------------------------------------------Matter is made of molecules, such as H2O, which is the water molecule.Matter can be one of three states, solid, liquid or gas.Water and ice are the same substance, but they are in different states.These states depend on the temperature of the molecules.When we heat a substance, the molecules move faster and try to take up more space. When we cool a substance, the molecules move more slowly.When we cool a substance to its freezing point, it becomes a solid.-------------------------------------------------------------------------------------------------------------In a solid, the molecules move very little.Their positions are almost fixed.To be fixed means that their positions don’t change.If we heat the molecules, they move faster and away from each other.The solid begins to melt, like ice cream on a hot day.-----------------------------------------------------------------------------------------------------------At a certain temperature, a solid begins to change into a liquid.The temperature at which a solid change into a liquid depends on the substance.For water, the solid begins to change into a liquid when its temperature rises to about 0 degree Celsius.For some substances, such as steel, the temperature at which it becomes a liquid is much higher.对于某些物质,如钢,它变成液体的温度要高得多。
