We are often referred to as carbon-based life forms. It is believed that these basic materials would be needed for the emergence of life elsewhere in the universe but some scientists argue otherwise, suggesting that life could form from different elements and materials.Life on Earth shows a wide diversity in forms, yet many contain basic similarities. Life is an ongoing process so it seems probable that life exists elsewhere in the universe in a multitude of different forms and stages of progression. Just as it is possible that life exists elsewhere in forms similar to the bacteria and viruses found on Earth, it is also likely that life forms may exist that are more advanced than humans. Even though many planets have harsh conditions in which life as we know it would not be able to exist, we should keep in mind that there are many creatures on Earth that can exist in harsh climatic conditions. Life could exist in the smallest organic molecules or in a form completely unknown to humanity that could go totally unrecognized. We assume that life could not exist on the giant gaseous planets, but it could very well be possible that some form of life completely beyond the scope of our imaginations may exist.We dont know whether life in any form exists on other planets elsewhere in the universe. Although we have made great strides in our search for extraterrestrial life and the exploration of space our technology is still in its infancy in the cosmic scheme of things. 1. The scientists speculated that there may be life on Mars _.A. because of its temperature B. because of the existence of water on itC. because of its thin atmosphere D. because it is similar to Earth in many ways2. What does the word “diversity” mean in Para. 2?A. Similarity.B. Variety.C. Possibility. D. Change.3. Which sentence is NOT true according to the passage? A. It seems possible that life exists elsewhere in the universe.B. It is likely that there are life forms which are more advanced than humans.C. There cant be lives elsewhere in the universe because many planets have harsh conditions.D. There are much to be explored and found for the galactic exploration.4. What does the expression “in its infancy” mean in Para. 4?A. Becoming an infant.B. At young age.C. In the process of growing up. D. In the initial stage.5. Whats the authors attitude towards the possibility of life on other planets?A. Positive. B. Negative.C. Neutral.D. Indifferent.passage2The child welfare system is a group of services designed to promote the well-being of children by ensuring safety, achieving permanency, and strengthening families to care for their children successfully. While the primary responsibility for child welfare services rests with the States, the Federal Government plays a major role in supporting States in the delivery of services through funding of programs and legislative initiatives.The primary responsibility for implementing Federal child and family legislation rests with the Childrens Bureau, within the Administration on Children, Youth and Families, Administration for Children and Families, U.S. Department of Health and Human Services (HHS). The Childrens Bureau works with State and local agencies to develop programs that focus on preventing child abuse and neglect by strengthening families, protecting children from further maltreatment, reuniting children safely with their families, or finding permanent families for children who cannot safely return home.The child welfare system is not a single entity. Many organizations in each community work together to strengthen families and keep children safe. Child welfare systems are complex, and their specific procedures vary widely by State. The goal of child welfare is to promote the well-being, permanency, and safety of children and families by helping families care for their children successfully or, when that is not possible, helping children find permanency with kin or adoptive families.1.

What does the word “primary” mean in Para.2?A. Most important. B. Pertinent.C. Imminent. D. Innocent.3. Which of the following is TRUE according to the passage?A. The primary responsibility for implementing Federal child and family legislation rests with U.S. Department of Health and Human Services (HHS) only. B. Few families first become involved with their local child welfare system because of a report of suspected child abuse or neglect.C. The Childrens Bureau works with State and local agencies to develop programs that focus on preventing child abuse and neglect.D. Child maltreatment does not include harm that a caregiver allows to happen or does not prevent from happening to a child.4. Many organizations in each community work together to _.A. strengthen familiesB. keep children safeC. both A and BD. None of the above5. What is the authors purpose of writing this passage? A.

It is not the tools a scientist uses but how he uses these tools that make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree too that knowing how to investigate, how to discover information is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.The scientists knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einsteins ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.1. What makes a scientist according to the passage?A. The tools he uses.B. The way he uses his tools.C. His ways of learning.D. The various tools he uses.2. The underlined part in the passage shows _.A. the importance of informationB. the importance of thinkingC. the difference between scientists and ordinary peopleD. the difference between carpenters and people with other jobs3. A sound scientific theory should be one that _.A. works not only under one set of conditions at one time, but also under the same conditions at other times B. does not allow any changes even under different conditionsC. can be used for many purposesD. leaves no room for improvement4. The author quotes the case of Albeit Einstein to illustrate _.A. that measurements are keys to success in scienceB. that accuracy of mathematicsC. that investigations are important in scienceD. that the mathematical calculations may test his investigations5. What is the main idea of the passage?A. The theory of relativity.B. Exactness is the core of science.C. Scientists are different from ordinary people.D. Exactness and ways of using tools are the keys to the making of a scientist.passage4A foreigners first impression of the U.S. is likely to be that everyone is in a rush often under pressure. City people appear always to be hurrying to get where they are going restlessly, seeking attention in a store, and elbowing others as they try to complete their errands. Racing through daytime meals is part of the pace of life in this country.Working time is considered precious. Others in public eating places are waiting for you to finish so that they too can be served and get back to work within the time allowed. Each person hurries to make room for the next person. If you dont, waiters will hurry you.You also find drivers will be abrupt and that people will push past you. You will miss smiles, brief conversations, and small courtesies with strangers. Dont take it personally. This is because people value time highly, and they resent someone else “wasting” it beyond a certain courtesy point.The view of time affects the importance we attach to patience. In the American system of values, patience is not a high priority. Many of us have what might be called “a short fuse.” We begin to move restlessly about if we feel time is slipping away without some return be this in terms of pleasure, work value, or rest. Those coming from lands where time is looked upon differently may find this matter of pace to be one of their most difficult adjustments in both business and daily life.Many newcomers to the States will miss the opening courtesy of a business call, for example, they will miss the ritual socializing that goes with a welcoming cup of tea or coffee that may be traditional in their own country. They may miss leisurely business chats in a cafe or coffeehouse. Normally, Americans do not assess their visitors in such relaxed surroundings over prolonged small talks. We seek out evidence of past performance rather than evaluate a business colleague through social courtesies. Since we generally assess and probe professionally rather than socially, we start talking business very quickly.1. The statement that Americans are impolite to their business colleagues is wrong.A. TB. F2. In the fourth paragraph, “a high priority” means “a first concern”.A. TB. F3. Americans evaluate a business colleague by establishing business relations.A. TB. F4. This passage mainly talks about how Americans do business with foreigners.A. TB. F5. We can infer from the passage that the authors tone in writing is praiseful.A. T B. Fpassage5People born in the summer are more likely to be healthy than those who arrive during other times of the year, new research suggests. The phenomenon could be caused by mothers getting more sun in pregnancy and passing on higher quantities of vitamin D to their unborn infant. A study of almost half a million British adults found babies born in June, July, and August were heavier at birth and taller as adults.For the first time the research also revealed girls born in the summer started puberty later an indication of better health in adult life. Early puberty in girls has been linked with a higher risk of diabetes, heart disease or breast cancer.Previous research has shown children born between June and October are likely to be slightly taller and have bigger bones than winter-born children believed to be related to vitamin D exposure during pregnancy.Babies born in autumn and winter are more likely to develop food allergies with sunlight exposure during pregnancy and vitamin D levels also thought to play a role in this. But being born in summer can have drawbacks - such as an increased risk of short-sightedness.1. According to the new research, babies born in summer are more likely to be healthy.A. TB. F2. Late puberty in girls has been related to an increased risk of diabetes, heart disease or breast cancer.A. TB. F3. Vitamin D exposure during pregnancy is believed to be connected with the height of the babies.A. TB. F4. Food allergies are more likely to take place among babies born in spring.A. TB. F5. Short-sightedness is one of the probable disadvantages for babies born in summer.A. T B. Fpassage6No one is glad to hear that his body has to be cut open by a surgeon and part of it taken out. Today, however, we neednt worry about feeling pain during the operation. The sick person falls into a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have operation felt all its pain.Long ago, operation had usually to be done while the sick man could feel everything. Soon after 1770, Joseph Priestley discovered a gas which is now called “laughing gas”. Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didnt seem to feel pain when they were using this gas. He decided to make an experiment on himself. He asked a friend to help him.Wells took some of the gas, and his friend pulled out one of Wells teeth. Wells felt no pain at all. As he didnt know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out. Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.1. It is not long since a man felt all the pain while being operated.A. TB. F2. Long ago, when the sick man was operated on, he could feel nothing.A. TB. F3. Using the laughing gas, the people seemed to feel pain during the operation.A. TB. F4. If a man took less laughing gas than he should have when an operation went on, he still felt pain.A. TB. F5. One who took too much of the laughing gas would die.A. T B. Fpassage7People in the United States honor their parents with two special days: Mothers Day, on the second Sunday in May, and Fathers Day, on the third Sunday in June.Mothers Day was proclaimed a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea tohave a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation.In 1909, Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910, the first Fathers Day was observed in Spokane. Senator Margaret Chase Smith helped to established Fathers Day as a national commemorative day, in 1972.These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.These two special days are celebrated in many different ways. On Mothers Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother
