Her job is to find families for French teenagers who expect to live with American families in the summer . Its 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 , family life was more accommodating . 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 annually come from abroad to spend and academic year in the United States , as well as the thousands more who participate 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. In searching for host families , who usually receive no pay , exchange programmes are increasingly broadening heir appeals to include everyone from young couples to retirees . “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 teen-agers on academic year exchange programmes worldwide .

The Guinness Book of Records says that mosquitoes have caused over 50 per cent of all human deaths since the Stone Age , excluding deaths from war and accidents ! Mosquitoes are found all over the world . Female mosquitoes usually feed on the blood of humans and animals . Mosquitoes often carry dangerous disease called malaria , which usually occurs during hot , rainy season . If a mosquito feed on the blood of a person with malaria , it becomes a carrier of the disease . It injects the disease into the next person it bites . So , for example , a tourist could be infected with malaria during a visit to Indonesia . The same tourist might then visit Thailand where another mosquito may bite him . This mosquito could then bite another person and spread the disease . People have used insecticides to kill mosquitoes and their eggs for a long time , but many in
