题目内容
The life of a professional tennis player is tough ________ you never seem completely free to do _______ you like --- even in the off-season.
A.when; what | B.because; that | C.as; whatever | D.when; whatever |
C
解析试题分析:考查连词辨析和宾语从句。本题第一空的as/because(因为)引导是原因状语从句;第二空的what引导的是一个宾语从句,whatever引导宾语从句并在句中作为动词like的宾语。句意:职业网球运动员的生活是很艰难的,因为你从来都不能自由地做你喜欢做的事情,即使在没有休赛的季节。故C正确。
考点:考查连词辨析和宾语从句
点评:宾语从句属于名词性从句一种,名词性从句分为主语、宾语、表语、同位语从句四种,除宾语从句外,同位语从句和定语从句的区别是高考常考点。宾语从句中的连接词that, whether, if在句中不充当任何成分,只起连接作用;连接代词who(ever), which(ever), whom(ever),whose(ever),what(ever)在句中做主语,宾语,表语和定语;连接副词when, why, where, how,在句中做状语。应从上下句的句法关系着手分析,切不可‘望句形生答案’总的来说,考生在解答此类题型时,可用排除法,造句法或者还原法,造句法就是仿造原句的语法功能仿造出一个易懂易理解的句子,帮助判断。
Researchers in over 80 nations are taking part in a project to conduct a decade-long census(统计) of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion.
In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish (海星) and other marine(海洋的)creatures.
Elsewhere in the world’s oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life.
“There are about 2,000 scientists worldwide involved,” said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. “Everywhere they’ve gone they’ve found new things,” he says. “The ocean basically is unexplored from the point of view of marine living things.”
Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration(迁移)routes and to discover places where sea life gathers.
According to Ron O’Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. “90% of all the information we have is from the top hundred meters of the ocean,” O’Dor states.
And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things.
Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census —which some say is only a small part of all the creatures living in the sea.
