Lakeland, Flo. April 29--Two cars fell to the bottom of a 30-foot sinkhole（灰岩坑）that appeared so suddenly that the drivers could not avoid it.

　　No one was hurt, but the incident was the fifteenth of its kind reported in this area so far this year.

　　At a town 13 miles from Lakeland, two bedrooms of one house dropped into a hole 60 feet across and 35 feet deep. Part of the next house was dangerous over the hole. The people in both houses had to be taken to safety.

　　Sinkholes have been happening without warning in this part of Florida for years. So far there is no way to predict（预言）when or where one will appear. But when one does, others usually follow in the same area, usually along a straight line.

　　The worst sinkhole appeared in 1965. It was 70 feet across and 150 feet deep. It destroyed one house and damaged several others.

　　One hole, 15 feet deep, opened up this year in the middle of a highway 19 seconds after a car had driven by. Others in the same area happened at night, damaging houses, swallowing up trees and parts of streets and causing 23 frightened people to run away from their homes in nightclothes.

　　Sinkholes happen when the weather is very dry. The earth at the surface begins to drop into holes underneath. This is how a sinkhole is formed.

（1）Sinkholes do not happen

[　　]

A. after a rainstorm

B. in a straight line

C. when it is very dry

D. at night

（2）When one sinkhole appears, others usually follow _______.

[　　]

A. everywhere

B. on straight highways only

C. in the neighborhood

D. immediately

（3）Sinkholes take place because _______.

[　　]

A. there are large holes under houses

B. Lakeland has an underground lake

C. wet earth sucks in heavy things such as cars and houses

D. dry earth changes position and fills underground holes

（4）The main idea of this passage is that _______.

[　　]

A. sinkholes have caused damage in the Lakeland area

B. sinkholes always happen

C. drivers can not avoid sinkholes

D. sinkholes are of very large size
