05 名词性从句 [考点一] 连接词 当名词性从句主干齐全，又不缺少状语时，用连接词引导。连接词有that,whether和if。 1.that引导的名词性从句that连接名词性从句，只起连接作用，不在从句中作成分。引导宾语从句时有时可以省略，引导主语从句，表语从句和同位语从句时不能省略。 The teacher informed us(that)we would have a test the next day. 老师告知我们第二天进行测试。 His plan is that he is going to buy a new car next year. 他的计划是明年买辆新车。 2.whether与if引导的名词性从句 (1)whether引导的主语从句既可放在句首也可放在句末，但if引导的主语从句只能放在句末，且前面需用it作形式主语。 Whether it is true remains a question.这是否是真的依然是个问题。 It is unknown if he will attend the meeting.他是否会来参加会议还不清楚。 (2)whether与if引导宾语从句时，大多数情况下可以互换，后面直接跟or not时用whether,用于介词后引导宾语从句时也用whether。 We don't know whether or not she was ready.我们不知道她是否准备好了。 (3)whether可引导表语从句和同位语从句，而if则不可以。 The question is whether it is worth doing.问题是它是否值得做。 The question whether the work was worth doing had not been decided. 这项工作是否值得做的问题还没有确定。 对点演练 单句语法填空 1.(2022·全国甲卷)We can't seem to make up our minds__________we want a modern city or a traditional one. 2.(2020·全国卷Ⅲ)We were so amazed_________they could stay underwater much longer than us local islanders, 3.(2020·全国卷Ⅲ)Housewarming parties get their name from the fact_________a long time ago people would actually bring firewood to anew home as a gift. 4.(江苏卷，25改编)Scientists have obtained more evidence_________plastic is finding its way into the human body. 5.(全国卷I)It clearly showed_________while likability can lead to healthy adjustment,high status has just the opposite effect on us. 6.(新课标I)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. 7.It's clear_________a solution is needed so a celestial(天体的)deep clean can take place. 8.But there is some debate over_________it was NOLA or Mobile,Alabama that had the first Mardi Gras back in the 1700s. 9.What is even more important is _________the earth cooled down,and water began to appear on its surface. 10.He has made it clear_________the meeting will not be postponed.
