题目内容

One-third of the country____covered with trees and the majority of the citizens_______black people.

A is；are????? B is；is??? C.are；are??? D.are；is

【答案】

【解析】A解析：考查主谓一致。第一个空前的主语为“这个国家的三分之一”，作为整体，故谓语动词用单数；第二个空前的? 主语为“大多数市民”，为可数名词复数，故谓语动词用复? 数，即A项正确。

【规律总结】当百分数.分数后面加名词或代词时，要根据这个名词或代词来决定其谓语动词的单复数形式。如果是复数名词或代词，谓语动词用复数；如果是单数名词(或不可数名词)或代词，谓语动词用单数。如：①Fifty percent ofthe students in our school are girls.我们学校百分之五十的学生是女生。②Three—fourths of the surface of the earth issea,.地球表面的四分之三是海洋。

ple — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可树)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Eu??rope, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish peo??ple starved when the crop failed during the "Potato Famine (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.
