Passage FourEvery culture and every country in the world celebrates New Year, but not everyone does it the same way. The countries in North America and Europe welcome New Year on January the first. This practice began with the Romans in the Middle East, New Year is when spring begins. People in China and Vietnam celebrate it on the first day of the Spring Festival, which is the first day of their calendar based on the moon. Rosh Hashana, which is the Jewish (犹太人的) New Year, comes at the end of summer. The Hindus (印度教教徒 ) in India celebrate the first day of each season, so they have four New Years.In all these cultures, there is a practice of making noise. People made noise in ancient times to drive away the evil spirits (妖精) from their homes. Today making noise is more of a custom than a religious rimIn the United States, many people stay up until midnight on New Year's Eve to watch the clock pass from one year to the next. Friends often gather together at a party on New Year's Eve, and when the new year comes, all ring bells, blow' whistles, sing songs, and kiss each other. A favorite Scottish song which everyone sings together is Auld Lang Sync. The words tell of old friends and good times.In all cultures, New Year's Day is a time when people think of new beginnings. They want to make the coming year better than the last one. Many people in the United States make New Year resolutions. These are specific promises that they make to improve their behavior, change their habits, and become better people. There are many jokes about how a person keeps his or her New Year resolutions.48. In ancient times, the practice of making noise was meant ______.A. to keep the evil spirits awayB. to have funC. to celebrate the coming of the new yearD. to keep to a custom

Drunken driving, sometimes called America's socially accepted form of murder, has become a national epidemic. Every hour of every day about three Americans on average are killed hydrunken drivers, adding up an incredible 350,000 over the past decade.A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American alcohol image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant.Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18 to 20-year-old drivers more than doubled, so the state recently upped it back to 21.Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop"responsible attitudes" about drinking and teach them to resist peer pressure to drink.Tough new laws have led to increased arrests and in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks.As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years' national prohibition of alcohol that began in 1919, which President Hoover called the"noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.?Which of the following sentences best concludes the main idea of this passage?A.Drunken driving has caused numerous fatalities in the United States.B.It's recommendable to prohibit alcohol drinking around the United States.C.The American society is trying hard to prevent drunken driving.D.Drunken driving has become a national epidemic in the United State.

共用题干That scientists have cloned a sheep sends academics and the public into a panic at the prospect that humans might be next. That's an understandable reaction.(46)___________,so it's not unreasonable to be concerned that it might threaten human society and dignity.Yet much of the ethical oppo-- sition seems also to grow out of an unthinking disgust. And that makes it hard for even trained scientists and ethicists to see the matter clearly.While human cloning might not offer great benefits to humarnty,no one has yet made a persuasive case that it would do any real harm,either.(47)_______That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower stature.But why suppose that cloned persons wouldn't share the same rights and dignity as the rest of us?A leading ethicist has suggested that cloning would violate the "right to genetic identity".(48)________It makes perfect sense to say that adult persons have a right not to be cloned without their voluntary,informed consent. But if such consent is given,whose "right"to genetic identity would be violated?So who will likely take advantage of cloning?Perhaps a grieving couple whose child is dying. (49)________But a cloned child born to such dubious parents stands no greater or lesser chance of being loved,or rejected,or warped than a child normally conceived.Infertile couples are also likely to seek out cloning. That such couples have other options(in vitro fertilization or adoption)is not an argument for denying them the right to clone.Or consider an example raised by Judge Richard Posner:a couple in which the husband has some tragic genetic defect. Currently,if this couple wants a genetically related child,(50)________They can reproduce naturally and risk passing on the disease to the child.They can go to a sperm bank and take a chance on unknown genes.They can try in vitro fertilization and dispose of any afflicted embryo though that might be objectionable,too.Or they can get a male relative of the father to donate sperm,if such a relative exists.This is one case where even people unnerved by cloning might see it as not the worst option.Even if human cloning offers no obvious benefits to humanity,why ban it?In a democratic society we don't usually pass laws outlawing something before there is actual or probable evidence of harm.Most important,human cloning should be governed by the same laws that now protect human rights.A world not safe for cloned humans would be a world not safe for the rest of us._______（49）A:they have four not altogether pleasant options.B:This might seem psychologically twisted.C:Theologians contend that to clone a human would violate human dignity.D:Parents might clone a child to have"spare parts"in case the original child needs an organ transplant.E:Cloning is a radical challenge to the most fundamental laws of biology.F: Where did he come up with such a right?

Text 3 Today,widespread social pressure to immediately go to college in conjunction with increasingly high expectations in a fast-moving world often causes students to completely overlook the possibility of taking a gap year.After all,if everyone you know is going to college in the fall,it seems silly to stay back a year,doesn't it?And after going to school for 12 years,it doesn't feel natural to spend a year doing something that isn’t academic.But while this may be true,it’s not a good enough reason to condemn gap years.There's always a constant fear of falling behind everyone else on the socially perpetuated“race to the finish line,”whether that be toward graduate school,medical school or lucrative career.But despite common misconceptions,a gap year does not hinder the success of academic pursuits－in fact,it probably enhances it.Studies from the United States and Australia show that students who take a gap year are generally better prepared for and perform better in college than those who do not.Rather than pulling students back,a gap year pushes them ahead by preparing them for independence,new responsibilities and environmental changes－all things that first-year students often struggle with the most.Gap year experiences can lessen the blow when it comes to adjusting to college and being thrown into a brand new environment,making it easier to focus on academics and activities rather than acclimation blunders.If you're not convinced of the inherent value in taking a year off to explore interests,then consider its financial impact on future academic choices.According to the National Center for Education Statistics,nearly 80 percent of college students end up changing their majors at least once.This isn’t surprising,considering the basic mandatory high school curriculum leaves students with a poor understanding of themselves listing one major on their college applications,but switching to another after taking college classes.It’s not necessarily a bad thing,but depending on the school,it can be costly to make up credits after switching too late in the game.At Boston College,for example,you would have to complete an extra year were you to switch to the nursing school from another department.Taking a gap year to figure things out initially can help prevent stress and save money later on.A gap year may save money for students by helping them____A.avoid academic failuresB.establish long-term goalsC.switch to another collegeD.decide on the right major

问答题Passage 2 A new form of cloning to provide every baby with an embryonic “twin”, from which spare body parts could be grown and life threatening diseases treated is expected to be approved within weeks by senior government advisers on medical ethics. If their report is accepted by ministers, it would mean that Britain—which 20 years ago pioneered the test tube baby and last year produced Dolly, the world’s first cloned mammal—could be the first to clone a human embryo. A working party from the Human Fertilisation and Embryology Authority (HFEA) and the Human Genetics Advisory Commission is expected to come down firmly against reproductive cloning, the process of replicating a living human being. It is expected to recommend government support of so called stem ceils. Stem cells are extracted and used to grow spare parts, treat diseases such as Alzheimer’s and Parkinson’s or address the debilitating effects of cancer, strokes and heart attacks. Dr Austin Smith, the scientist likely to be granted the first licence for the work, said that within the next 12 years it would be routine for every baby to have an embryonic clone. “All it takes now is financial investment,” said Smith, director of Edinburgh University’s centre for genome research. The crucial discovery of embryonic stem cells, from which skin, bone, muscles, nerves and vital organs grow, was made earlier this month by scientists in America. In a submission to the HFEA, Smith said that in order to isolate these cells it is only necessary for the embryo to develop in the laboratory for six days, well within the 14-day limit of current regulation. The cells would then be grown and manipulated to make anything from blood or brain cells to tissue for repairing damaged organs and, ultimately, parts that could be transplanted without fear of the host body rejecting them. The development is likely to meet strong opposition from the church. Dr Donald Bruce, Director of the Society, Religion and Technology Project of the church of Scotland Said that creating an embryo in the knowledge that it would then be destroyed was “very disturbing” to most people. Father Paul Murray, secretary to the Catholic bishops joint bio-ethics committee, said that whatever the potential benefits, it should be regarded as “intrinsically evil” because the research depended on the use of foetal material. However, Professor Christine Gosden, professor of genetic medicine at Liverpool University, one of the four senior government advisers on the cloning sub-committee, said there would be no opportunity for abuse. For many years, patients with Parkinson’s disease who did not respond to drugs have been treated with brain cells extracted from aborted foetuses, a practice approved by a committee led by the Rev Dr John Polkinghorne, the prominent ethicist. Gosden said the arguments for the use of aborted foetal cells and therapeutic cloning were similar: “Before you have a disease, it is easy to say, ‘I would not use cells derived from a foetus’, but if you suffer from that disease, and that is your only hope, your approach can be quite different.” 1. What is the new form of cloning discussed in the passage? What is the purpose of such cloning? 2. Summarise the different views on embryo cloning discussed in the passage. 3. Explain the statement “All it takes now is financial investment.” in para. 6. 4. What is the significance of the discovery of embryonic stem cells?
问答题Practice 3 The United States is a federal union of 50 states. The District of Columbia is the seat of the national government. The Constitution outlines the structure of the national government and specifies its powers and activities. Other governmental activities are the responsibilities of the individual states, which have their own constitutions and laws. Within each state are counties, townships, cities and villages, each of which has its own elective government. All government in the United States is “of, by and for the people”. Members of Congress, the President, state officials, and those who govern counties and cities are elected by popular vote. Heads of federal departments are named by the President, and judges are either elected directly by the people or are appointed by elected officials. Voting ballots are unsigned and marked by the voters in private booths so that no one else can find out for whom a citizen is voting. Public officials may be removed from office for failing to perform their duties properly as well as for serious violations of law.
