英语 必修·第一册 作业与测评 Period 4　Developing ideas 课时作业(四) Ⅰ　阅读 Australia is the only major honey­producing country that has so far managed to control the spread of a mite (螨) which is harmful to bees. The first step is pouring gas into the beehive. Then it's time to wait. The job is finished when the hive is burned the next day. This cycle has been on repeat near a port in eastern Australia, part of a government effort to protect the country's multimillion dollar honey industry. Millions of bees have been destroyed to help control the spread of the deadly mite, which reappeared in the country near the Port of Newcastle. If the mite became established in Australia, it could cost the nation's honey industry more than $70 million a year, in addition to its effect on the crops that rely on bee pollination (授粉)． The mites, which are reddish­brown and about the size of a sesame (芝麻) seed, can spread from bee to bee and through beekeeping equipment. If left untreated, the mites could kill an entire colony of honey bees, the government has said. It's not easy to control the mite. One of the biggest challenges in the current control effort is figuring out the location of infected hives and mapping their spread in a vast region, according to Danny Le Feuvre, the acting head of the Australian Honey Bee Industrial Council. It's necessary to control the Port of Newcastle and the hives within a 31­mile radius (半径) of it. The port is a major shipping destination and one of the world's busiest export centres for coal. So far at least 600 hives have been destroyed in the area. “The beekeepers are very nervous at the moment，” Mr Feuvre said. He said he was confident the country would be able to control the spread, given its history of previous eradication efforts of honey bee mites and strict controls at all airports stopping passengers from bringing live plants, soil, fruits and vegetables into Australia. 篇章导读：本文是一篇新闻报道。为了挽救蜂蜜产业，澳大利亚杀死数以百万计的蜜蜂以控制一种有害螨虫的传播。 1．Why do people pour gas into
