Question

阅读理解 　　WASHINGTON－Laura Straub is a very worried woman．Her job is to find families for foreign teenagers who expect to live with American families in the summer． 　　It’s not easy, even desperate． 　　“We have many children left to place：40 out of 75, ” said Straub, who works for a foreign exchange program called LEC． 　　When exchange programs started 50 years ago, more families were accommodating．For one thing, more mothers stayed home． 　　But now, increasing numbers of women work outside the home．Exchange-student programs have struggled in recent years to sign up host families for the 30 000 teenagers who come from abroad every year to spend an academic year in the United States, as well as the thousands more who take part in summer programs． 　　School systems in many parts of the US, unhappy about accepting non-taxpaying students, have also strictly limited the number of exchange students they accept．At the same time, the idea of hosting foreign students is becoming less exotic(异国情调的)． 　　In searching for host families, who usually receive no pay, exchange programs are increasingly broadening their requests to include everyone from young couples to the retired． 　　“We are open to many different types of families, ” said Vickie Weiner, eastern regional director for ASSE, a 25-year-old program that sends about 30 000 teenagers on academic-year exchange programs worldwide． 　　For elderly people, exchange students “keep us young－they really do, ” said Jean Foster, who is hosting 16-year-old Nina Porst from Denmark． (1) Why do foreign teenagers come to American families?

Answer 1

答案：1．C;2．D;3．A;4．B;
解析：

(1)	推理判断题。十几岁的孩子到美国家庭中是去体验生活，了解文化，而不是去享受生活。
(2)	细节理解题。由第四段可知“五十年前，很多家庭很乐于助人，其中的一个原因是很多家庭里的女主人是专职太太”，因此有条件接收foreign teenagers。
(3)	细节理解题。由倒数第三段中“…are increasingly broadening their requests to include everyone from young couples to the retired”一句可知交换机构一直在不断扩大寄宿家庭的范围，hosting family的范围扩大到从年轻夫妇到退休夫妇的各种家庭。
(4)	推理判断题。由“elderly people”及“keep us young…”可知老年人感到接收foreign teenagers可以使他们保持年轻的心态，从而使他们受益。
