高考语法填空抢分热点之名词性从句

一、考点精讲

名词性从句的引导词：

1.that 无词义，只起引导作用，可以省略，但两个或两个以上that引导的宾语从句并列时，从第二个开始that不能省略。

2.what引导名词性从句，既起引导作用，又在从句中作一个成分，起双重作用，不能省略。

3.连词whether“是否”，可以引导主语从句、表语从句、介词之后的宾语从句以及同位语从句，而if“是否”只能引导动词后面的宾语从句。

4.引导名词性从句的连接副词有when、where、how、why，在判断名词性从句引导词的使用时，如果句子缺成分，缺什么，补什么。

二、高考题经典解读

1.______(56) is so breathtaking about the experience is the out-of-this-world scenes.

【答案】What

【解析】考查主语从句。句意：这段经历最让人激动的是那些脱离世界的场景。设空处无提示词，应考虑填冠词、介词、连接词，又因为空格在句首，后面是谓语动词is，这里应该填一个连接词，引导主语从句，从句缺少引导词和主语，且指物，所以连接代词What符合语境，其双重作用。位于句首，首字母用大写。故答为What。

2.While they are rare north of 88℃，there is evidence ______ they range all the way across the Arctic，and as far south as James Bay in Canada.

【答案】that

【解析】考查同位语从句。句意：虽然它们在88℃以北很少见，但有证据表明，它们一直分布在北极，南至加拿大的詹姆斯湾。该句是含让步状语从句的复合句，主句部分是there be句型，设空处填that，引导同位语从句，说明evidence的具体内容。故答案为that。

3.Research suggests an increase in voice is a signal ________ someone is lying.

【答案】that

【解析】考查同位语从句。句意：研究表明声音的提高是一个人在撒谎的标志。分析句子结构可知，空格后的句子意思完整，不缺少任何成分，所以用that引导同位语从句，用于解释说明signal的具体内容。故答案为that。

4.It is no use doing ________ you like; you have got to like ________ you do.

【答案】what; what

【解析】考查名词性从句。句意：干你喜欢的事是没有用的;你得喜欢你所干的事。第一空引导宾语从句且在从句中作like的宾语，表示“……的事情”，第一空填what;第二空引导宾语从句且在从句中作do的宾语，表示“……的事情”，第二空也用what。故答案为what; what。

三、实战演练

1.It is our responsibility, so ________ I don't want now is to push it to the students.

【答案】what

【解析】考查主语从句。句意：这是我们的责任，所以我现在不想把它强加给学生。设空处引导主语从句，因为引导词在从句中作want的宾语，表示“……的事情”，所以用what引导该从句。注意：that引导主语从句时不充当句子成分。故答案为what。

2.If you take a look around your kitchen or office, chances are ___1___ you’ll notice that you are surrounded by plastic water bottles,take-out cups, plastic grocery bags and food packages.

【答案】that

【解析】考查名词性从句。句意：如果你看看你的厨房或办公室，很有可能你会注意到你周围都是塑料水瓶、外卖杯、塑料购物袋和食品包装袋。固定句型：chances are that…，意为“很可能”，其中that引导表语从句。故答案为that。

3.Well-made, long-lasting clothing is_____1_____ we should buy and wear.

【答案】what

【解析】考查表语从句。句意：我们应该购买和穿质量好，耐穿的衣物。分析句子可知，be 动词后面是表语从句，从句中的buy 和wear缺少宾语，设空处所填引导词要起双重作用，所以用连接代词what。故答案为what。

4.What students do at college seems to matter much more than ___8___ they go.

【答案】where

【解析】考查宾语从句。句意：学生在大学里做什么似乎比去哪里（哪所大学）更重要。这里表达去“哪所大学”，表示地点，作状语。故答案为where。

1.discovery

2.stopping

3.placed

4.to

5.it

6.sent

7.stresses

8.louder

9.whether 10.naturally

【解析】

1.discovery 考查名词。句意：我们总是认为在度假期间让我们的植物无人照看是可以的，但最近的一项研究有了一个新发现。句中lead to“引起，导致”，其中to为介词，其后用名词作to的宾语，discover是动词，其名词是discovery。故答案为discovery。

2.stopping 考查动名词。句意：一些科学家通过切断烟草植物和番茄植物的茎并停止浇水来测试它们。介词by后跟动名词作宾语，cutting 和stop由并列连词and连接，所以设空处用stop 的动名词stopping。故答案为stopping。
