蚂蚁和蚜虫的关系简直可以说是亲密无间的，有时候，你会看到一群蚂蚁背着蚜虫川流不息地跑来跑去，那是蚂蚁在给蚜虫搬家。当蚜虫在一片植物上大肆蚕食，只剩下残茎败叶之后，蚂蚁就把这群祸害转移到另一处食物充足的地方去，使蚜虫能够饱食终日，好排泄出更多的蚜蜜来。在蚂蚁搬家的时候，也不会丢下为它提供美餐的好朋友不管。确定了新居之后，小蚂蚁就会把蚜虫一个一个搬到附近的植物上去。蚂蚁不仅是蚜虫的“卫士”，还是蚜虫的“保姆”。冬天临近了，雌蚜排出了一个个越冬卵。蚂蚁很担心这些卵会被冻坏，便不辞劳苦地把它一个个搬到外面晾晒，晒完后再搬回巢去。到了次年早春，蚜卵孵化了，这下又忙坏了小蚂蚁，它又主动承担了喂养小蚜虫的任务。直到春暖花开，蚂蚁又把小蚜虫一个个搬出洞来，放到植物上，让它去啃食鲜嫩的茎叶，以便自己从它的屁股后面捞取一点蚜蜜。（选自《中学生必读文库》）

The Guidance Department （教导处）at Berryville High School has a staff of eleven teachers. Most of their work is done with the students. But the staff sees a lot of parents, too.
“Parents meetings make clear monthly diagram（图表）.”says Mildred Freman, head of the Guidance. “This diagram stays much the same from year to year. The busy months are October, March and May. ”
September, the beginning of a new school year, starts rather slowly. Few parents come in. Most of these want to talk about the schedules. October brings many problems caused by some students. Some parents are called in. Others come by themselves. Things quiet down in November. December is a quiet month. “It’s the holiday. ”Ms Foreman says, “People want to come in, I know, but they decide to wait until after New Year’s Day.”
Report cards go home just before Christmas holidays. Bad marks bring parents in as school opens again. This happens again in March, another report card month. May is always the year’s busiest month. That’s when parents begin to think that their children may be asked to stay in the same grade again. They come in to see if anything can be done before things are decided in June.
