One day, around Christmas time, fishermen off the west coast of Peru started on their traditional fishing trip. Much to their surprise, there were no fish! They knew immediately what had happened. Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months!

El Nino is a warm current that comes and goes along the west coast of South America. It got its name from fishermen in Peru more than a century ago. Every few years, they noticed a sudden warming in the normally cool Pacific water where they fished. Because this warming often came about around Christmas, they called it El Nino, which is Spanish for the “Christ Child”. Generally, El Nino occurs every three to seven years and lasts only a few weeks to a month or more.

El Nino warms the water it flows through. Because the fish and sea birds need cold water to live, many of them die when El Nino comes through. El Nino also causes both floods and droughts. It is believed that El Nino may have caused the 1993 Mississippi and 1995 California floods. And at the same time, it may have caused droughts in South America, Africa and Australia.

El Nino has occurred thirteen times within the last fifty years, bringing natural disasters to many countries such as Indonesia and Peru. However, El Nino does not often trouble China. During this period China was badly hit by El Nino only once. In 1998, North China had a terrible drought, while South China was troubled by floods.

1.The underlined word "current" （in Paragraph 2）most probably refers to “______”.

A. water B. wind C. atmosphere D. climate

2.According to the passage, which of the following is TRUE about El Nino?

A. It happens in November and December.

B. It was named by some Spanish fishermen.

C. It only happens in South America.

D. It lasts a few weeks or more.

3.If El Nino happens, the following will take place EXCEPT ______.

A. rises in temperature of the sea water

B. diseases spreading around the world

C. floods and droughts

D. death of fish and sea birds

4.The purpose of this passage is ______.

A. to discuss the prevention of El Nino

B. to explain how El Nino trouble farmers

C. to let us know about El Nino

D. to tell us how to prepare for El Nino
