外研版英语中考英语名词性从句易错题集锦-名师教育含答案解析 一、初中英语名词性从句 1．They lost their way in the forest, and ___ made matters worse was that night began to fall. A. it B. which C. that D. what 【答案】 D 【解析】【分析】本题中含有一个主语从句what made matters worse，其中的what引导起这个主语从句，同时在主语从句中做主语。AC两项不能引导主语从句，which在引导名词性从句的时候总是含有疑问的语义，而本句中并没有疑问的语义。句意：他们在森林里迷路了，情况更糟糕的是天又黑了。故D正确。 2．_____ is known to us all is that China has launched Shenzhou VII spaceship, ____ made the country's first spacewalk successful. A. That; what B. What; which C. It; which D. As; that 【答案】 B 【解析】【分析】句意：众所周知，中国已经发射了神州7号宇宙飞船，这是中国首次成功的太空行走。第一空处为主语从句，从句缺少主语，需用what引导；第二空所在句子是个定语从句，先行词为整个主句的内容，从句中缺少主语，需用which引导。故选B。【点评】考查名词性从句和定语从句，本题涉及主语从句和非限制性定语从句的应用。 3．Exactly _________ the potato was introduced into Europe is uncertain, but it was probably around 1565. A. whether B. when C. why D. how 【答案】 B 【解析】【分析】句意：土豆被引进欧洲具体的事件不被确定，但是可能是在1565年左右。根据时间状语round 1565得知这里是指时间不确定。故选B。 【点评】考查名词性从句，本题涉及when引导的主语从句。 4．It matters little ______ a man dies, but _____ matters much is ______ he lives. A. how; what; how B. how; it; how C. why; it; why D. that; what; that 【答案】 A 【解析】【分析】句意：一个人如何死去并不重要，重要的是他如何生活。it为形式主语，how从句为真正的主语。What matters much （=the thing that matters much）。第一个how引导的是一个主语从句；it作形式主语；what引导的是主语从句；第二个how引导的是表语从句。故选A。

That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。因此选A。 【点评】考查名词性从句，本题涉及that引导的主语从句和what引导的宾语从句。 2． is clear to the members of the committee is that the President will not give in to their demands. A. Who B. It C. As D. What 【答案】 D 【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 3．Has it been announced ______? A. when are the planes to take off B. that are the planes to take off C. where are the planes to take off D. when the planes are to take off 【答案】 D 【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。 【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。 4．--- made her ashamed of herself? --- the lowest mark in her class. A. What; Because she got B. Was it what; Getting C. What was it that; That she got D. What was it that; Get 【答案】 C 【解析】【分析】句意：——是什么让她对她自己感到羞愧？——是她获得了她班上的最

So he is(√) [析] “so+be动词/助动词+主语”的倒装结构表示前面所述情况也适用于后者，意为“……也是这样”;“so+主语+be动词/助动词”的陈述结构表示对前述情况的肯定，意为“……确实如此”。 19. 例--- He didn’t go to school yesterday, did he?-- _______, though he didn’t feel very well.

A. 7 minutes walk B. 7 minute walk C. 7 minutes' walk D. 7 minute's walk 答案为C。本题考查名词所有格用法。当名词的复数以-s结尾时，则只需要加“'”即可，则“7分钟的距离”为“7 minutes' walk”。 21. You can not imagine how much I ______ on this dress. Is it beautiful? A. paid B. took C. cost D. spent [剖析] 答案为D。本题考察四个表“花费”的动词辨析。主语为人，且和介词on搭配的动词是spend。 22. ---- Do you know _____ university student who is talking with Joe?---- Yes， she，s my cousin, Kate.
