WELCOME UNIT Unit 6 At one with nature Period 4 　Developing ideas 课时作业（四） 课时作业（五） 目录 CONTENTS 1 2 小精读 3 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. Ⅰ Ⅱ 课时作业（四） 目录 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.

If left untreated, the mites could kill an entire colony of honey bees, the government has said. Ⅰ Ⅱ 课时作业（四） 目录 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. Ⅰ Ⅱ 课时作业（四） 目录 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 a
