WASHINGTONLaura Straub is a very worried woman.  Her job is to find families for French 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 Paris based foreign exchange programme called LEC.

When exchange programmes started 50 years ago, more families were willing to help others. For one thing, more mothers stayed home.

But now, increasing numbers of women work outside the home. Exchange student programmes have struggled in recent years to sign up host families for the 30,000 teenagers who come from abroad every year to have some courses for one year in the United States. as well as the thousands more who take part in summer programmes.

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 programmes 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 programme that sends about 30,000 teenagers

on one-year exchange programmes worldwide.

For elderly people,exchange students “keep up young——they really do,” said Jean Foster,who is hosting 16-year-old Nina Porst from Denmark.

5.Foreign teenagers come to American families wilh the purpose of .

A.finding thier parents in America         B.finding good jobs in America

C.learning the culture of America          D.enjoying the life of America

6.In the past, Straub’s job was easy, because American families .

A.needed more money to live              B.had fewer children to support

C.had spare rooms to rent                 D.were not as busy as now

7.To deal with the problem in recent years, Straub and her workmates have to .

A.ask different kinds of families for help    B.limit the number of the exchange students

C.borrow much money to pay for the costs  D.force some families to accept students

8.From the last paragraph we can conclude that __________.

A.exchange students are welcome in America

B.exchange students must pay much money to the host families

C.American students don’t want to join the exchange programmes

D.old Americans can benefit from hosting exchange students

阅读《目送》（节选），完成问题。

　　①华安上小学第一天，我和他手牵着手，穿过好几条街，到维多利亚小学。九月初，家家户户院子里的苹果和梨树都缀满了拳头大小的果子，枝丫因为重而沉沉下垂，越出了树篱，勾到过路行人的头发。

　　②很多很多的孩子，在操场上等候上课的第一声铃响。小小的手，圈在爸爸的、妈妈的手心里，怯怯的眼神，打量着周遭。他们是幼稚园的毕业生，但是他们还不知道一个定律：一件事情的毕业，永远是另一件事情的开启。

　　③铃声一响，顿时人影错杂，奔往不同方向，但是在那么多穿梭纷乱的人群里，我无比清楚地看着自己孩子的背影——就好像在一百个婴儿同时哭声大作时，你仍旧能够准确听出自己那一个的位置。华安背着一个五颜六色的书包往前走，但是他不断地回头，好像穿越一条无边无际的时空长河，他的视线和我凝望的眼光隔空交会。

　　④我看着他瘦小的背影消失在门里。

　　⑤十六岁，他到美国作交换生一年。我送他到机场。告别时，照例拥抱，我的头只能贴到他的胸口，好像抱住了长颈鹿的脚。他很明显地在勉强忍受母亲的深情。

　　⑥他在长长的行列里，等候护照检验；我就站在外面，用眼睛跟着他的背影一寸一寸往前挪。终于轮到他，在海关窗口停留片刻，然后拿回护照，闪入一扇门，倏忽不见。

　　⑦我一直在等候，等候他消失前的回头一瞥。但是他没有，一次都没有。

　　⑧现在他二十一岁，上的大学，正好是我教课的大学。但即使是同路，他也不愿搭我的车。即使同车，他也戴上耳机——只有一个人能听的音乐，是一扇紧闭的门。有时他在对街等候公车，我从高楼的窗口往下看：一个高高瘦瘦的青年，眼睛望向灰色的海；我只能想象，他的内在世界和我的一样波涛深邃，但是，我进不去。一会儿公车来了，挡住了他的身影。车子开走，一条空荡荡的街，只立着一只邮筒。

　　⑨我慢慢地、慢慢地了解到，所谓父女母子一场，只不过意味着，你和他的缘分就是今生今世不断地在目送他的背影渐行渐远。你站立在小路的这一端，看着他逐渐消失在小路转弯的地方，而且，他用背影默默告诉你：不必追。
