求答案及解析。求讨论

Answer 1

1.A
what引导主语从句,并在从句中作does的宾语.
is后是不定式作表语,由于前面的主从中有does,故作表语的不定式可以省略,
所以就选A了.
2.C
as well as连接两个名词作主语时,谓动与前一个名词相一致,
即与the teacher相一致,故用is不用are,排除AB.
be about to不能与时间状语连用,据此排除D. 所以答案选C.
3.D
twenty metres high 作表语. twenty-metre-high只能作定语, 不能作表语.

Answer 2

1. A    主语从句， does   是及物动词， 缺宾语用 what ，  dictionary  是可数名词， 表泛指前面用 a ,   help  作表语， 前面省略动词不定式符号 to  

2. C  . as well as  连接两个主语时， 谓语和第一个主语保持一致，be  about to  不和时间状语 tomorrow 连用， 故选C。

3. D 。  表示二十米高，  几个正确表达法是 twenty-metre high

                                                               twenty-metres  high

                                                                twenty metres  in height 
    

Answer 3

B 前面一段What dictionary does是主语从句吧，后面的help用to help表示目的。

A go是谓语动词，不需要再加be动词
A 有—符号的都不用变复数
