Popular breakfast foods in the United States, as in many other countries around the world, include coffee, milk, juice, eggs and bread. Some other breakfast items served in the United States are thought by many to be traditionally American. However, they actually come from other countries.A very popular breakfast food in America is the pancake---a thin, flat cake made out of flour and often served with maple syrup. The idea of the pancake is very old. In fact, pancakes were made long ago in ancient China.Bagels, a round thick bread with a hole in the middle, are also popular for breakfast in America. Polish people in the late 1600s came up with the idea for the first bagels and this new kind of bread soon took off across Eastern Europe.In the late 1800s, thousands of Jews from Eastern Europe traveled to the United States and brought the recipe for bagels with them. Today, New York bagels are said to be the best in the world. Many people have them with cream cheese for breakfast on the go.Doughnuts (usually spelled “donut” in the United States) came from France. They were served to American soldiers in France during World War Ⅰ(第一次世界大战). After the war, American soldiers asked cooks in the United States to make doughnuts for them. Now, served with coffee, they are a very popular breakfast food across the United States.41. This reading is mainly about _______.A. famous places in the United States to eat breakfastB. popular American breakfast foods coming from ChinaC. the most popular types of pancakes in the United StatesD. the history of popular breakfast foods in the United States

共用题干Some Sleep Drugs Do More Than Make You SleepThe United States Food and Drug Administration(FDA)has ordered companies to place strong new warnings on thirteen drugs that treat sleep disorders.It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs.Last Wednesday,the FDA announced that some of these drugs can have unexpected and dangerouseffects.These include the risk of life-threatening allergic（过敏性的）reactions.They also include rareincidents of strange behavior.These include people cooking food,eating and even driving while asleep.The patients later had no memory of doing these activities while asleep.Last year,a member of the United States Congress said he had a sleep-driving incident.PatrickKennedy , a representative from Rhode Island,crashed his car into a security barrier near the building wherelawmakers meet.The accident happened in the middle of the night and no one was hurt.Mr.Kennedy saidhe had earlier taken a sleep medicine.He said he was also being treated with a stomach sickness drug thatcan cause sleepiness.The FDA did not say in its announcement how many cases of sleep-driving it has documented.However,the New York Times reported last year about people who said they had strange sleep events after taking the drug Ambien.Some reported sleep-driving and sleep-walking.Others said they found evidence after waking in the morning that they had cooked food or eaten in their sleep.But they had no memory of carrying out the activities.An FDA official says that these serious side effects of sleep disorder drugs appear to be rare.But,he also said there are probably more cases than are reported.He said the agency believes the risk of such behaviors could be reduced if people take the drugs as directed and do not drink alcohol while taking the drugs.The FDA has advised drug companies to carry out studies to investigate the problem.The FDA warned that some sleeping pills______.A:can help people to learn to cookB:prevent people from driving while asleepC:present life-threatening risk to patientsD:have severe effect on a patient's long-term memory
Text3 Genetically engineered crops are safe for humans and animals to eat and have not caused increases in cancer,obesity,gastrointestinal illnesses,kidney disease,autism or allergies,an exhaustive report from the National Academies of Science released Tuesday found.Overall,genetically engineered（GE）crops saved farmers in the United States money but didn't appear to increase crop yields.They have lowered pest populations in some areas,especially in the Midwest but increased the number of herbicide-resistant weeds in others.There's also no evidence that GE crops have affected the population of monarch butterflies,the report said.To gauge whether foods made from genetically modified crops were safe for human consumption,the committee compared disease reports from the United States and Canada,where such crops have been consumed since the mid-1990s,and those in the United Kingdom and westem Europe,where they are not widely eaten.No long-term pattem ofincrease in specific health problems after the introduction of GE foods in the 1990s in the United States and Canada was found.There was no correlation between obesity or Type n diabetes and the consumption of GE foods.Celiac disease,which makes humans intolerant of gluten,increased in both populations.Patterns in the increase in autism spectrum disorder in children were similar in both the United Kingdom and the United States,the committee reported.Overall the report concluded that there were no differences in terms ofa higher risk to human health between foods made from GE crops and those made from conventionally-bred crops.Food&Water Watch,a government accountability group in Washington D.C.,said the committee's ties to the biotech industry and other corporations create conflicts ofinterest and raise questions about the independence ofits work."Critics have long been marginalized,"said Wenonah Hauter,the group's executive director.A significant portion of American consumers are concerned about the safety or other effects of foods made with genetically modified crops,often called GMOs for genetically modified orgarusms.A survey released last year by the NPD Group,a market research firm,found that 57%ofAmericans were concemed that genetically modified foods posed a health hazard.The food industry has taken notice.In 2015,Progressive Grocer,a trade publication,reported that total U.S.sales of food and beverage products labeled"non-GMO"reached$10 billion during 2014.The National Academies report will likely not sway these consumers,said Phil Lempert,a Los Angeles-based food industry analyst."It's an emotional issue,it's not a science issue,"he said.33.The word"marginalized"（Para.6）is closest in meaning toA.condemned.B.abandoned.C.neglected.D.evaluated

In spite of all stories of prosperity in the Unites States, not only does poverty exist there, but crimes of various types have been increasing at an alarming rate. Most acts of violence were committed by young people.57% of the criminals arrested in 1979 were youths below 25 of age. Everyone agrees that crime is partly a result of bad material conditions: poverty, lack of education, living within a settled home, being parent less, sufferings from other kinds of misfortune, etc. There are also other factors than material conditions which are responsible for the sharp increase of crime rate. In the first place, some state laws provide a death penalty but some not. Secondly, the Constitution allows every citizen to carry weapons for his own protection. It is therefore possible and easy for anyone in the country to get a gun. Finally, there has been too much shown on TV and too much reported in newspaper of all kinds of crime, the details of which are so accurately described that even children know how to duplicate what they have seen or read. All these have resulted in a high frequency of crimes committed both by professional criminals and by nonprofessional ones in murder, drug smuggling, robbery, etc. The author intends to tell the readers that_________.A. the United States is a wealthy country although poverty and crime exist thereB. crime has become a serious problem in the United States, although it is said to be a prosperous oneC. despite the fact that crimes have been increasing rapidly in the United States, it is a country of prosperityD. in spite of stories about poverty and crime in the United States, it is prospering at an increasing r

单选题Questions 21 to 25 are based on the following passage. Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly. A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining. In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States. In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period. The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected. Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.The authors of the Ambio study have found that（）Aforests get rid of lead pollution faster than expectedBlead accumulations in forests are more difficult to deal withClead deposits are widely distributed in the forests of the USDthe upper layers of soil in forests are easily polluted by lead emissions
