As millions of playthings are recalled, doctors are reminded that the risks of lead exposure continue for young patients.
Lead is such a well-known health(危害)- perhaps even contributing to the fall of the Roman Empire- that it came as a shock to discover that toys played by children could contain lead. Doctors are now dealing with the aftershocks.
Just how dangerous is this exposure? That’s the question physicians are being asked by parents who find a lead-polluted Elmo, of Dora. Millions of others toys, lunch boxes and pieces of jewelry manufactured in China have been recalled because they contain lead either in the paint that coats them or as a component of the plastic used to make the item more flexible. The lead content in some of the toys recalled this summer was 180 times the amount allowed by law. Some pieces of jewelry were almost 100% lead.
Experts advise that the items do cause a risk and that doctors should urge parents to check the comprehensive lists of recalled products on the Consumer Product Safety Commission’s Web site and return any appearing on those lists to the manufacturers.
If exposure is suspected, a blood test is in order . Since there is no safe level of this universal (普遍存在的) element, the risk face by children for lead poisoning and its accompanying threat of learning disabilities and behavior problems is considerable.
Doctors who have toys in their waiting rooms also are advised to see if any of them have been recalled and to check for chipped, flaking paint-even on those that haven’t yet been recalled—since new announcements of toy risk continue.
1. Why does the author mention “the fall of the Roman Empire”?
A. To tell us a strange story.
B. To warn us to keep away from lead.
C. To explain why the Roman Empire fell.
D. To show how terrible lead poisoning is.
2.What is Dora according to the passage?
A. The name of a kind of metal.
B. The name of a girl.
C. The name of a toy.
D. The name of a toy company.
3.What should parents do if they are not sure whether their kids have ever touched such toys or not?
A. They should ask the experts for advice.
B. They should have a medical examination.
C. They should have their children blood-tested.
D. They should collect all the toys and check online first.
4. From the report we can infer that_____.
A. children who are exposed to lead have learning disabilities
B. the unsafe toys have all been listed on the website
C. lead is used mainly to make the products flexible
D. some toy and jewelry manufacturers will suffer heavy losses

It was in the Victorian Era(维多利亚时期) that the novel became the leading form of literature in English. Most writers were more concerned to meet the tastes of the middle class. The best known works of the period included the works of Charles Dickens and the Bronté sisters and others.
Charles Dickens came on the literary scene in the 1830s. Dickens wrote vividly about London life and the struggles of the poor. Most of his works were written in a very humorous style, which was popular with readers of all classes.
The Bronté sisters were English writers of the 1840s and 1850s. They began to write from early childhood. In 1846 they published the first book at their own expense as poets; however, their book attracted little attention, selling only two copies. Then the sisters turned to writing novels, each producing a novel in the following year.
An interest in rural matters and the changing social and economic situation of the countryside may be seen in the novels of Thomas Hardy and a number of others.
Literature for children developed as a single style. Some works became well-known, such as those of Lewis Carroll and Edward Lear. Adventure novels were written for adults but are now generally grouped in the list for children. Helen Beatrix Potter was an English author at the end of the Victorian Era, best known for her children's books, which featured animal characters. In her thirties, Potter published the highly successful children's book The Tale of Peter Rabbit in 1902.
1.What can we know about Charles Dickens from the text?
A. He described the struggles of the poor in London.
B. He showed an interest in rural matters in his writing.
C. He focused on changing social and economic situation of the countryside.
D. He published the highly successful children's book.
2.Which is TRUE about the Bronté sisters?
A. They were English writers of the 1830s.
B. They paid to have their first book published.
C. They began their writing from adulthood.
D. Their first book was successful.
3.The author states in the last paragraph that ________．
A. society changed rapidly in the Victorian Era
B. Thomas Hardy was not as famous as Lewis Carroll
C. Edward Lear was famous for writing about animals
D. adventure novels were not written for children at first
4.This text is mainly about ________.
A. literature in the Victorian Era
B. writing styles in the Victorian Era
C. famous works in the Victorian Era
D. the importance of literature in the Victorian Era

Hunter Bliss, like more and more American students, left the United States to go to college. In the 2011-2012 school year, 46,571 U.S. students registered for degree programs in 14 countries. The top destination countries were the U.K. and Canada, followed by France, Germany, Italy and some other European countries. Germany, in particular, has attracted many more American students in recent years, like Hunter Bliss.
In 2012, there were more than 4,000 American students completing bachelor's, master's and doctor's degrees in Germany. The Institute of International Education (IIE) says that the number of U.S. students completing college degrees in Western Europe increased by about 5 percent from 2010 to 2012. American students choose to study in another country for two main reasons. First, international experience is becoming more important in the modern job market. Second, the cost of higher education has continued to rise in the United States. Rising tuition (学费) costs make education abroad—particularly in countries that charge no tuition-attractive to American students, says the IIE.
Many American students choose Germany because of the low cost of education there. German public universities do not charge tuition fees. And many universities in Germany offer courses in English, too. College education in the US is seen as a privilege and expected to cost money but in Germany it is seen as an extension of a free high school education where one expects it to be provided.
The German government has been eager to encourage students to come to Germany for another reason. Like many countries in Western Europe, German's population is becoming older, and fewer young people are entering college and the job market. The German government hopes to attract skilled foreign students who will stay in Germany.
1.Which country attracted American students most in the 2011-2012 school year?
A. Germany. B. France. C. Britain. D. Italy.
2.The main reason why US students choose to study in Germany is that ________.
A. many universities there offer courses in English
B. the cost of education is relatively low there
C. studying abroad matters in their job hunting
D. it is much easier to find a job than in the USA
3.What does the underlined word “it” in Paragraph 3 refer to?
A. Overseas education. B. High school education.
C. College education. D. Public education.
4.What does the text mainly talk about?
A. More and more US students choose colleges overseas.
B. Reasons why more students study in foreign countries.
C. Western Europe manages to attract foreign students.
D. Advantages and disadvantages of German education.
