1.考得是情态动词,cant表示有把握的否定.翻译为不可能.mustn't表示禁止,may not没把握的否定,needn't表示不需要
2.考宾语从句,缺什么补什么,所以是what to do
3,考短语意思,应该是远离草地,所以是a喽,这就要自己积累了
4这是固定用法,俗称小模糊句型.因为宾语或主语太长了,就用it代替,真正的是to后面的
5.这题考代词,another后面只能跟单数,被指代的是trousers所以是c
6,matter可作可数名词也可作动词,it是第三人称,故排除a,它作为名词可数故d错,在你的学习范围里没有b这种用法,所以c对
7,考感叹句的句型用法,sunshine是不可数的,所以没有a,what+形容词+主语+谓语,固定句型
8quite是副词修饰nice,a是修饰horse的数量词,所以是c
9,这就是考你对句子的理解了,把答案带进去翻译的通就是对的了
10,这是固定用法,A.so dose gina.jina也是.so am i我也是
这是我的理解,不知道能不能帮到你啊,

不知道
我回头再给你查吧
