The largest earthquake (magnitude里氏9.5 ) of the 20th century happened on May 22, 1960 off the coast of South Central Chile.
It generated (生成) one of the most destructive Pacific-wide tsunamis (海啸). Near the
generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isla Chiloe. The largest tsunami damage occurred at Isla Chiloe-the coastal area closest to the epicenter(震中). Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland.

People in different countries use different types of money: yuan in China, pesos in Mexico, pounds in the United Kingdom, (51) in the United States, Australia and New Zealand. They may use different currencies, but these countries, and probably all countries, still have one thing (52) : Germs on the banknotes.
Scientists have been studying the germs on money for well over 2, 100 years. (53) the turn of the 20th century, some researchers began to suspect that germs living on money could spread disease.
Most studies of germy money have looked at the germs on the currency within one country. In a new study, Frank Vriesekoop and other researchers compared the germ (54) found on bills of different countries.

I hear many parents complaining that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are clutching at (attempting to seize) one another’s hands for reassurance.
They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up crowded round listening to the same record. Their reason for thinking or acting in thus—and—such a way is that the crowd is doing it. They have come out of their cocoons(蚕茧) into a larger cocoon.

A. have much difficulty understanding each other
B. lack confidence
C. dare not cope with problems single-handed
D. are very much afraid of getting lost
