求英语高手帮我解答几道题.1.This problem is ____that one.A.so easy as B.as difficult as C.much difficult than D.less easier than 2.It’s fun ___a comedy movie. A,to watch B.watch C.watching D.for watching 3.there used ___
1.B
as...as可以用于肯定句/否定句,而so...as只能用在否定句中,排除A；
C错在much difficult不是比较级,more difficult才是；
Deasier已经是比较级,无须在其前加上less又表比较；
2.A
固定句型：It be + 形容词/名词 + to do sth.
其中,it是形式主语,to do sth是真正的主语
3.B
used to + 动词原形“过去曾经/常常”,排除AD；
there be句型要有be动词,排除C
4.B
同意对方肯定句的观点,用“so + 同一主语 + be/助动词/情态动词”,排除AC；
前句含有助动词has,排除D
5.A
定语从句,如果先行词（book）前面被the only所修饰时,则关系代词只能用that
6.A
第一句的could并不表示过去时,只是表示委婉语气,所以宾语从句无需用过去时,排除BD；
for five days要求句子谓语是延续性动词,而go是瞬间性动词,排除C
7.B
定语从句中指物的关系代词如果在定语从句中充当介词(on)的宾语,且两者一起提前至定语从句句首时,则只能用which,且不能省略.
即：on which we are living = on the land we are living = we are living on the land
8.C
throw短语作the food的后置定语,且两者之间是被动关系,所以用过去分词thrown；
固定的系表短语：go bad 变质
9.C
感叹句 What a lovely day!= How lovely the day is!
用Let's开头的祈使句的反意疑问句,用shall we提问
10.A
together with连接主语时,动词的数采用就远原则,即该题的主语是Jeany,为单数,所以谓语动词也用三单形式,排除BD；
for several days要求动词能延续,而come是瞬间性动词,排除C
11.C
此题为被动语态,即其谓语结构是：be + 过去分词；
而不定式做宾语补足语时所省略的to,在被动句中必须补上to
12.C
后面是疑问词how many pounds所引导的宾语从句,排除D（不定式不是句子）；
宾语从句必须采用陈述句序,排除B；
weigh作为“重达...”之意时,和主语it之间是主动关系,不是被动关系,排除A
