1.Why do you think many people immigrated to other countries? Do you want to immigrate to another country? Why or Why not?As time goes by ,more and more people we are with immigrate to other countries .Why do people immigrated to other countries ?The desire for a better life is sometimes so big that it makes people leave their countries and their families and work in other countries. They know that they will have to face difficult moments, that they won't be able to communicate with the persons around them, that maybe they will have to work in illegal conditions to get the money they need for their families, but all take these chances and they hope they will succeed.On the other hand, there are persons who immigrate just for the sake of the persons they love. They leave their families to make other families with the persons they love. Women go to meet the men they love who have chosen other countries to start a new life, even if they miss their families and their friends. Maybe they don't have a place where to work but they are capable of waiting to see what destiny has for them.In my opinion immigration into a foreign country with different language is a culture shock. I think language is the main barrier between nations. Overcoming this barrier is a very complicated task, to a majority of the people. Espesially to adults. So most people feel more comfortable within a society of people talking on the same language. When you cannot talk to people around you as fluently as you speak on your mothertongue language you feel yourself like a disabled person. Even when you can talk about everyday subjects you still may feel bad, because you cannot fulfill yourself and so you're forced to do an unskilled or less skilled work and you're limited in communication.2.My understanding of happiness.I would like to share with you my understanding of happiness. I hold my point of view that happiness is simple .Just as i am writing something about happiness , i think it is a kind of happiness.Maybe, some of you will disagree with me. Though happiness is so easy to come, why so many people pursue happiness so hard and still can not abtain it. Why so many people ,especially some celebrities ,reveal their unhappiness hidden beneath all their fun: depression. alcoholism, drug addiction,broken marriage,troubled children,profound loneliness. Yes,those are controlvertial problems.Actually,i may say they complicated the happiness.The more they want to devote all their energy on grasping happiness ,the less they will have of it.Some people think happiness is equal to money ,they never content with their living condition ,they want to possess more and more money to buy a bigger house,a more fascinating car,the fashionest clothes.They want more glamorous party,more luxurious vacation.So,they get growing pressure to earn more and more money. They are crazy in pursuitinghappiness.As a matter of fact,they forced themselves into a painful circle.Because happiness is not so complex.It has little to do with money .Rare people can get it through work it directly.It sometimes comes when you are not notice.It is as simple as a feeling ,just like ,everymorning when you wake up with a fine day ,the sun is shinning,the birds are singing.You may regard it as a prosperous day .At that time you may feel a feeling that is so sweet.Yes,it is a kind of happiness.When night falls,everything is quiet,the moon is bright,the starts are twinkling.You will have a nice dream because of this beautiful day.Yes,it is also a kind of happiness.Indeed,happiness to me is thus simple.A raassuring smile from a friend makes me happy;a slight salutation makes me happy.;reading books makes me happy;listenning to music makes me happy.Any little spell time makes me happy.Just like now i finish my expression makes me happy;you response to my writing will makes me happy. That is all i want to say .I am happy,that is my happiness. Happiness, to me , is thus simple.At last ,may you all happy.3.Why are the new dry areas forming and expanding all over the world?A balanced ecosystem is a healthy ecosystem. But now there are many new dry areas forming and expanding all over the world.Firstly, Unsustainable farming methods contribute to soil degradation.overuse of chemical fertilizers, failure to employ crop rotation and irresponsible irrigation practices rob the soil of the last of its nutrients. When topsoil is depleted of humus, it's either too loose or too compacted, both of which can lead to destructive erosion.All life depends on the quality and fertility of the soil. Plants can't grow when soil is allowed to degrade. This means no food crops for humans and no grazing crops for animals. All the rain in the world won't help infertile topsoil. It will only wash away.Perhaps the greatest cause of soil degradation and desertification is an explosion in world population, particularly in developing countries. Throughout the 1990s, dryland regions experienced a population growth of 18.5 percent, mostly in desperately poor, developing nations . In their daily struggle to survive, these expanding populations have put a deadly strain on their environment.Grazing animals are just as bad. Grasses are essential to anchoring arid topsoil in a dryland region. When animals are allowed to graze recklessly, they remove all of the native grasses, exposing the topsoil to destructive erosion forces like winds and sudden thunderstorms.Firewood is the fuel of choice for many people living in developing countries. This has led to unchecked clear-cutting of forests in dryland ecosystems. Trees play a crucial role in anchoring down topsoil and slowing down the force of winds. When too many trees are removed,windstorms and dust storms ensue.4. Introduce one traditional Chinese festival or western holiday. (Talk about its origin, the story related to it, or how people celebrate it?)Traditional Chinese FestivalChina is a country with many ethnic groups and a rich culture heritage .Of all the traditional festivals, perhaps the most popular ones are the Spring Festival, the Lantern Festival, the Dragon Boat Festival, and the Mid-autumn Festival. Besides, there are many important traditional fes tivals such as Ching Ming Festival, New Year’s Day, National Day. Now I will introduce the most popular festivals to you.The Spring FestivalThe Spring Festival, also know as the Lunar New Year, is the most important traditional festival in China, which takes place in late January or early February. The historical reason for beginning the year during cold weather is that it is the time between the “autumn harvest and winter storage” and “spring plowing and summer weeding”. In other words, this is the time for rest and relaxation after a year’s toil, and for celebration as well.In addition to the practical reasons of having the Spring Festival during the cold months, a Chinese folklore offers another explanation. According to Chinese legends, a demon called Nian would torment people once a year during the winter. The people gathered to discuss howto deal with Nian. Some people suggested that the demon was afraid of the red color, flames and loud noises. So they put red couplets on their gates, set off firecrackers and beat gongs and drums to drive Nian away. Their ideas worked and Nian fled. Thus, the customs of celebrating the Spring Festival were born and passed down.During the month of January or February, Chinese families clean their houses, set off firecrackers, post pictures of the Door God and couplets on their gates. On the eve of the Spring Festival, it is a folk custom to stay up late or all night to pray for peace and prosper—together banquet is usually a must for every Chinese family. The most popular food enjoyed by both the rich and poor is Jiaozi, or dumplings, which is supposed to bring good fortune.On the first day of the New Year, everybody wears new clothes and greets relatives and friends with bows and gongxi, wishing each other the best during the New Year.In recent years, the Spring Festival has become a public holiday. People usually have several free days for attending family dinners, traveling, going to the movies or concerts or just watching holiday special TV programmes.The Lantern FestivalThe fifteenth day of the first lunar month is also an important traditional festival in China where various types of lanterns are exhibited.The lantern exhibition is a custom that has persisted throughout history. In recent years, the increase in living standards has led to various splendid lantern exhibition all over the country. Such occasions are colourful and present picture perfect scenes with the bright moon shining down on hundreds of colorful lanterns. In addition to lantern exhibitions, the Lantern Festival includes plays, firework displays, acrobatics and dances, which are all part of the celebration.Traditionally, every family eats yuanxiao on the night of the Lantern Festival. Yuanxiao, a symbol of family unity, affection and happiness, is a glutinous, rice-flour dough stuffed with sweet stuffings such as sugar and bean paste. Therefore, the Lantern Festival is also called they Yuanxiao Festival.The Dragon Boat FestivalThe Dragon Boat Festival，or the Duanwu Festival, falls on the fifth day of the fifth lunar month. This Festival is widely accepted as a day to commemorate Qu Yuan, China’s greatest poet of the Waring States Period. People respected Qu Yuan for his efforts to make State of Chu strong and prosperous and for his dedication to such ideals. However, he become frustrated with the status quo and ultimately committed suicide by drowning himself in the Miluo River. On the day of Duanwu, the day of Quan Y uan’s death, people rushed from all over, rowing dragon boat s on the river in an attempt to find his remains, which were thought to havedrifted downstream never to be recovered. As part of the festival, people thrown rice-filled bamboo tubes into the river as an offering. During the Duanwu Festival, it is also a common practice to eat zongzi, which is a rice pudding wrapped up with reed leaves. The reed leaves give a special flavor to the food.Commemoration of Qu Yuan during the Duanwu Festival shows his popularity as a poet and man who made great contribution to his motherland. In 1957, Qu Yuan was selected by the world Peace Council as one of the cultural figures to be memorized by the world .The Mid-autumn Festival falls on the fifteenth day of the eighth lunar month because the eighth lunar month is mid-autumn and the fifteenth is the middle of that month. On that night the moon is supposed to be brighter and fuller than any other night. In China, a full moon is symbolic of family reunion, which is why that day is also known as the “Day of Reunion.”In ancient china, the moon was considered by scholars as a symbol of brightness, purity, and goodness. Poets of the past wrote many beautiful odes to the moon. Not only was the moon an inspiration to writers but it was also a source of many myths and legends. The most popular myth was a story about a woman named Chang E who flew to the moon and lived in the Moon Palace with trees and flowers around. It is believed that she is now happy about the leisure and tranquility on the moon. But fromtime to time she is missing the earthly life.During the festival, people eat the moon cake, which is made of wheat flour and sweet stuffings such as sugar and lotus seed powder. The festival is a time for families to gather to burn incense and eat fruits in addition to the moon cake. The cake is traditionally cut into pieces that equal the number of people in the family. While tradition abounds during this festival, the essence of this festival is the harmony and happiness of family life, which is something that can be understood by all.Valentine's FestivalValentine's Festival ，also know as the Double-Seventh day, falls on the seventh day of the seventh lunar month. It is originated from the ancient legends ─Cowboy and the Weaver's story .According to the legend, Weaver is very talent, hand is very agile, able to weave beautiful clouds Jin, she married after the Cowboy put the brocade embroidery skills imparted to the villagers, and all the women rushed from all over, longing for the wisdom and knowledge for weaving . in addition to this,Their love touched magpies, they can see one time one year.After the folk worship, generally half of the offerings for the Weaver and the rest that we can eat, most of food are seasonal food, such as dumplings, noodles and fruit oils. We called them "clever food" .many people also eat peanuts, fruits, tea and play the Qi Qiao game.5.What bad habits do you have in your campus life?

What can we do to prepare for an earthquake? What should we do when an earthquake strikes?An earthquake strikes suddenly. Being prepared for any emergency is especially important in the school environment. Time is always against you in such a situation, and having a plan in place can save lives and provide a sense of control in a chaotic situation. Preparedness refers to things that can be done before an earthquake actually strikes.Safe Reaction TrainingStudents and teachers must all know what to expect and, more importantly, what to do when an earthquake strikes. One of the most important things to do during an earthquake is to drop down, seek coverand hold on while the ground shakes and rolls. Students and teachers should identify safe places before an earthquake ever strikes. They should regularly practice taking cover. This will save time and lives as students will be able to react confidently. Teachers should set up safe places where students and staff can meet after the trembling has stopped. Evacuation should only take place after the earthquake.AftershocksOnce an earthquake has passed, schools must put into action their emergency response plans. It's important for teachers and students to know that aftershocks are common and, if they follow a large magnitude earthquake, they can cause further damage. In fact, the aftershock can make hazards created by the original earthquake worse. Students must be ready to take cover at any time because aftershocks arrive unannounced and while never as strong as the original earthquake, they can be very powerful and dangerous.8.How many types of memory do we have? Describe the characteristics of each type?There are generally three types of memory: sensory memory, short-term memory and long-term memory.Sensory memoryThe sensory memories act as buffers for stimuli received through the senses. A sensory memory exists for each sensory channel: iconicmemory for visual stimuli, echoic memory for aural stimuli and haptic memory for touch. Information is passed from sensory memory into short-term memory by attention, thereby filtering the stimuli to only those which are of interest at a given time.Short-term memoryShort-term memory acts as a scratch-pad for temporary recall of the information under process. For instance, in order to understand this sentence you need to hold in your mind the beginning of the sentence you read the rest.Short term memory decays rapidly (200 ms.) and also has a limited capacity. Chunking of information can lead to an increase in the short term memory capacity. This is the reason why a hyphenated phone number is easier to remember than a single long number. The successful formation of a chunk is known as closure. Interference often causes disturbance in short-term memory retention. This accounts for the desire to complete the tasks held in short term memory as soon as possible. Long-term memoryLong-term memory is intended for storage of information over a long time. Information from the working memory is transferred to it after a few seconds. Unlike in working memory, there is little decay.There are two types of long-term memory: episodic memory and semantic memory. Episodic memory represents our memory of eventsand experiences in a serial form. It is from this memory that we can reconstruct the actual events that took place at a given point in our lives. Semantic memory, on the other end, is a structured record of facts, concepts and skills that we have acquired. The information in semantic memory is derived from that in our own episodic memory, such that we can learn new facts or concepts from our experiences.9.My views on cosmetic surgery. Do you ever want to have cosmetic surgery? Why or Why not?You see advertisements on the television, you see them in the papers and magazines, you are told that slim is beautiful, and that you need perfect skin. You are constantly asked to vote in telephone votes to keep you favorite icon from getting chucked off some television program. That person is your idol, and in some cases you would love to look like them.You are told cosmetic surgery can solve all of your problems, and straight away you buy into this thinking, if I get this done my life will be so much better.Some people will settle with maybe a breast implant and stop there. However, others will become so obsessed with changing nearly everything about themselves, that they will end up looking completely different form what they did.After surgery there is not telling how it will look, so how do you knowthat after all the pain and expense, you are going to be happy with your new look? What is causing all of the insecurity, and is the media completely to blame?In this day and age there is a lot of pressure on young people, especially young girls, to look good. However, that should not be a reason to go and get cosmetic surgery.Cosmetic surgery is surgery after all, and all surgery is risky no matter what you are having done. There have been many cases where cosmetic surgery has gone wrong, some are high profile whilst others are never really heard of.There have been cases of breast implants bursting, lip collagen implants going drastically wrong. Overall, you can never be sure that your Cosmetic Surgery will run completely smoothly. In order to reduce the risks of surgery, you should choose somebody who knows exactly what they are doing. Scarily, there are some really dodgy plastic surgeons out there that are only after the money.So always make sure you go with a surgeon which you can trust, and who has the right qualifications. After all, it is surgery and you are bargaining with your life!Remember; try to not let other people influence your decisions, if you feel surgery is what will make you happier, then it has to be done just for you and nobody else.10.What is DNA testing? What is it used for? What are the pros and cons of DNA testing?DNA testing is a controversial technology. It has been used as conclusive evidence in countless court cases. It has liberated many incarcerated criminals and convicted many more. It has identified fathers, mothers and siblings. It is highly sensitive and tamper-proof. As DNA exists throughout the body, any tissue can be analyzed.On the other hand, there are downsides to DNA testing, including civil liberty infringements resulting from individuals who are analyzed without agreeing to testing and the storage of DNA profiles on innocent people. Also, although DNA is extremely accurate, there is concern that trace amounts of DNA in a crime scene can falsely implicate an innocent person.The largest concern about DNA testing, however, appears to be about the future. The possibility for parents to genetically modify their children or for insurance companies to use DNA profiles to discriminate against people with certain character traits is very frightening to many. Forensic ToolDNA is the most precise and technologically advanced method of identifying criminals and victims. It has replaced fingerprinting as the most accurate method of identification.While it can take several weeks before results of a DNA tests are available, in most cases, conclusive results are within millionths of a percent of being 100 percent accurate.In cases where victims are unidentified, a match of DNA can give the victim an identity. More commonly, however, it is used to pinpoint criminals such as rapists and murderers who leave DNA evidence at the scene of a crime.Paternity & Family IssuesDNA testing can effectively determine the identity of a child's father. By testing the mother, alleged father and child, patterns can be identified that determine the likelihood of paternity. These tests are considered 99.99 percent conclusive and are legally viable in establishing paternity and child support orders.DNA testing can also be used to identify other family members, such as twins who were separated at birth or cousins seeking confirmation for genealogical research. It can also establish twin zygosity, which shows whether twins are identical or fraternal.In rare instances (approximately one dozen cases per year), hospitals can confuse children and give parents the wrong babies. In this case, maternity testing can identify which child belongs with which mother. VersatilityAll body tissue contains DNA. A test can be performed on blood, hair, skin cells or any other available tissue without losing reliability. At crime scenes, this is a valuable facet of DNA testing.Since DNA is unaffected by outside contaminants such as acids, bases or other chemicals, a person cannot alter the results of their DNA test. Even tests that use DNA from cells inside the mouth are unaltered by eating or drinking.Civil LibertiesCountries around the globe have addressed concerns that DNA testing is an infringement of civil liberties.In Britain police are allowed to gather DNA samples from anyone arrested for a recordable offense. Because of this, Britain has the largest DNA database in the world.Germany, the UK and Australia have passed or are considering passing laws restricting paternity testing. These laws require all concerned parties to consent before DNA can be gathered to settle paternity disputes. It also bans gender determination of fetuses, testing for disease predisposition and gene testing by employers and insurance companies.In the United States, DNA samples can exist in databases permanently. The majority come from convicted criminals, but many come from people who have been exonerated or proven innocent.Because DNA tests can be conducted on any body tissue, individuals donot necessarily have to concede to DNA testing in order to be tested. It is because of this that civil liberty organizations are concerned opponents of DNA testing and data storage.Data ConfusionThere is concern from some sources that an innocent person could be convicted of a crime because of inaccurate DNA testing. This is a common refrain in courtrooms where defense lawyers are faced with unfavorable DNA evidence. According to their claims, a crime scene could be analyzed in such a way that trace amounts of DNA from an uninvolved person could be tested and identified, implicating the uninvolved individual without identifying the true criminal.Because these tests are considered so precise, voicing this unsubstantiated concern is one of few avenues of recourse for defense lawyers and defendants in a courtroom.The FutureThe movie "Gattaca" featured a world where children were genetically constructed for perfection. In the movie, there are two classes of human: those who are genetically perfect and those who are genetically inferior. Depending on genetic makeup, individual careers, diseases, and life expectancy are all determined at birth.Critics of DNA technology fear these ideas and consider them a likely reality. The ranks of these critics are made of conspiracy theorists,technophobes, some scientists and the general public who believe these hypothetical realities that they view on television or read about in books. These people fear the day that "Gattaca" becomes reality, and insurance companies, employers and others are allowed to genetically profile individuals and discriminate accordingly.。
