People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular. Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco bums, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person′s breathing muscles. Smokers usually take in small amounts that the body can quickly break down. Nicotine can make new smokers feel dizzy (头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers′ risk of heart disease and stroke. Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases. ___________ doesn′ t make one′ s heart beat as usual.A.TarB.NicotineC.Lung diseaseD.Leave

American literature begins with American experiences.Long before the first colonists arrived,before Christopher Columbus,before the Northmen who"found"America about the year 1000,native Americans lived here.Each tribe's literature was tightly woven into the fabric of daily life and reflected the unmistakably American experience of linking with the land.Another kind of experience,one filled with fear and excitement,found its expression in the reports that Columbus and other explorers sent home in Spain, French and English.In addition,the journals of the people who lived and died in the New England wilder- ness tell unforgettable tales of hard and sometimes heartbreaking experiences of those early years. Experience,then, is the key to early American literature.The New World provided a great variety of experiences,and these experiences demanded a wide variety of expressions by an even wider variety of early American writers.These writers included John Smith,who spent only two-and-a-half year on the American continent.They included Jonathan Edwards and William Byrd,who thought of themselves as British subjects,never suspecting a revolution that would create a United States of America with a literature of its own.American Indians,explorers,Puritan ministers,frontier wives,plantation owners-they are all the creators of the first American literature.What does"that hope"in the first paragraph refer to?A:The hope that America would be discovered.B:The hope to start a new life.C:The hope to see the mysteries of the New Worid.D:The hope to find poverty here.

共用题干The Dangers of Secondhand SmokeMost people know that cigarette smoking is harmful to their health.Scientific research shows that it causes many kinds of diseases.In fact,many people who smoke get lung cancer. However,Edward Gilson has lung cancer,and he has never smoked cigarettes.He lives with his wife Evelyn,who has smoked about a pack of cigarettes a day throughout their marriage.________(46)No one knows for sure why Mr. Gilson has lung cancer. Nevertheless,doctors believe that secondhand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people's cigarettes.________(47)The US Environmental Protection Agency reports that about 53,000 people die in the United States each year as a result of exposure to secondhand smoke.The smoke that comes from a lit cigarette contains many different poisonous chemicals.In the past, scientists did not think that these chemicals could harm a nonsmoker's health._________(48)They discovered that even nonsmokers had unhealthy amounts of these toxic chemicals in their bodies.As a matter of fact,almost all of us breathe tobacco smoke at times,whether we realize it or not. For example,we can not avoid secondhand smoke in restaurants,hotels and other public places.Even though many public places have nonsmoking areas,smoke flows in from the areas where smoking is permitted.It is even harder for children to avoid secondhand smoke._________(49)Research shows that chil- dren who are exposed to secondhand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as are children of nonsmokers.The risk is even higher for children who live in homes where both parents smoke.People are becoming very aware of the dangers of secondhand smoke._________（50)__________（50）A:Recently,though,scientists changed their opinion after they studied a large group of nonsmokers.B:The Gilsons have been married for 35 years.C:This smoke is called secondhand smoke.D:However,secondhand smoke is dangerous to all people,old or young.E:As a result,they have passed laws which prohibit people from smoking in many public places.F: In the United States,nine million children under the age of five live in homes with at least one smoker.
问答题Practice 8 The United States has long been known as a “melting pot”, because many of its people are descended from settlers who came from all over the world to make their homes in the new land. The first immigrants in American history came from England and the Netherlands. Attracted by reports of great economic opportunities and religious and political freedom, immigrants from many other countries flocked to the United States in increasing numbers, reaching a peak in the years 1880—1914. Between 1820 and 1980 the United States admitted almost 50 million immigrants. Some 1,360,000 American Indians, descendants of North America's first inhabitants, now reside in the United States. Most live in the West, but many are in the south and north central areas. Of the more than 300 separate tribes, the largest is the Navaho in the Southwest. Black people were first brought to America from Africa as slaves. Their descendants now make up nearly 12 percent of the population. They once lived mainly in the agricultural South but now are scattered throughout the nation.
问答题Practice 5 It is obvious today that America has defaulted on this promissory note insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check; a check which has come back marked “insufficient funds.” But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. So we have come to cash this check—a check that will give US upon demand the riches of freedom and the security of justice. We have also come to this hallowed spot to remind America of the fierce urgency of now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to open the doors of opportunity to all of God's children. Now is the time to lift our nation from the quick sands of racial injustice to the solid rock of brotherhood. ( I have a dream—Martin Luther King, Jr.）
