　�、�. 單句改錯

　　1．I didn't know what one to buy because these books were all useful to me.

　　答案與解析：what→which　此處表示“不知道該買哪一個”意義，故“疑問詞＋不定式”結構中的疑問詞應用which。

　　2．You want to know that everthing is going in our school.

　　答案與解析：that→how　賓語從句的引導詞在從句中作狀語，表示go的程度，表示“我們學校的情況如何”，故用how。

　　3．The problem is what the “Play” doesn't work at all.

　　答案與解析：what→that　表語從句的引導詞在從句中不作成分，而且不表示意義，故用that。what在名詞性從句中需要作主語、賓語等。

　　4．There is no doubt whether I will achieve great progress in English learning with your assistance.

　　答案與解析：whether→that　否定句或疑問句中doubt后的從句用that引導，肯定句doubt后的從句用whether/if引導。There is no doubt that...“毫無疑問……”。

　　5．At that time， I just wondered that my mother was so delighted.

　　答案與解析：that→why　根據(jù)wonder判斷，引導詞表示“為什么”意義，故用why。句子表示“我不明白為什么媽媽那么高興”。

　　6．Which is worse， they spat and even threw rubbish into the lake.

　　答案與解析：Which→What　What is worse是固定用法，意為“更糟糕的是”。

　　7．I went up and asked what I could help them.

　　答案與解析：what→if/whether　 賓語從句的引導詞不需要在從句中作成分，再根據(jù)ask判斷句子的引導詞表示疑問意義，故應為if/whether。

　　8．As is known to all that millions of graduates crowded into the job market each year.

　　答案與解析：As→It　本句是一個it作形式主語，that引導的從句作真正主語的句子，故改為it。如果用as，則為As is known to all， millions of graduates...。

　　9．That you should learn is how to write down the most important words， not the whole sentence.

　　答案與解析：That→What　主語從句的引導詞需要在從句中作learn的賓語，故用what。

　　10．The main reason for this was because my mother didn't know how to cook anything when she got married.

　　答案與解析：because→that　was后是表語從句且從句中不缺少成分，故用that引導。
