Question

The killer bees are coming! By the time you read this they will have reached Texas. They will also reach all the warmer areas of the United States. Scientists as well as farmers wait for them with a mixture of fear and wonder.

The killer bees should not be coming at all. Nature did not put them on this direct path for the United States; human beings did. The killer bees are from Africa. But in 1957 a scientist from Brazil got some of these killer bees for his experiments. The aim(目的)was to produce a better bee. However, an accident happened: a guest beekeeper let twenty-six of the queen bees escape by mistake. Before long, groups of killer bees took off for the woods.

Since that time, the wild killer bees have multiplied(繁殖)many times over. By 1998, their population was over 1015, They have spread all over South America, Central America, and most of Mexico. The United States is the next stop.

Are the killer bees really killers? Yes, they are. In their first thirty years in America, they have killed thousands of hens, pigs, and other animals. While no one knows the exact(确切的)number, it is believed that several hundred people have also been killed.

So be careful! Killer bees are on the way, Scientists have no idea what to do with them yet. There must be a way.

Answer 1

答案：A;A;C;C;B
提示：

1题由第二段“The aim was to produce a better bee”可知答案。 2题a guest beekeeper let twenty-six of the queen bees escape by mistake. Before long, groups of killer bees took off for the woods. 所以是A. 3题由第三段可知，the killer bees 先是在南美传播开来，后在中美，最后才来到美国，故应是自南向北发展。 4题由第二段中的“The killer bees should not be coming at all”,可知the killer bees本不应该在美洲繁殖并传播开来的，都是人惹的祸。
