1.是答案错了.
2. this book is different （）that one and they’ren different （）colours
a.to,to b.from,on c.from,in d.from from
选c,be different from与.不同,be different in在.方面不同
3.现在完成时有2种用法,一,用在瞬间动词,表示对现在造成后果,如i have left my keys at home.造成后果是现在无法开门了.要注意如果有表示过去的时间状语时就要用一般过去式,如：i left my keys at home yesterday.
二,用于延续性动词表示动作或状态持续到现在.一般有时间状语since..., for..., recently, lately, in the recent years, over the past ten days, lately, these days, 等等.
4.he lived here （since two years ago）对括号里的提问.
原句就有问题,因为有since做时间状语应该用现在完成时的.ago是对的.He has lived here since two years ago.改成How long has he lived here?
5.reading brings us( pleasure) 解释括号里的意思和词性.
名词,乐趣.
6.how long has jack （）mary ?
sorry i don't knowthey have（）
a. married to,got married b.married ,married c.been married to ,got married d.been married with,got married
选c.marry的用法：marrry sb和某人结婚,瞬间动词；be married to和某人结婚,延续性动词,表状态；get married/ be married结婚了,延续性动词,表状态.
第一个空格问how long,所以要用延续性动词；第二个空格“他们已经结婚”,也表示状态,“处于婚姻的状态中”,所以是get married 或者be married
6.i have （）interested in swimming since i was five years old.
a.have been b.have become
同上,be表示延续性,状态,become是瞬间动词,由于有since i was five years old,持续一段时间的,所以要用延续性动词
7.to my （surprise）
“令我惊讶的是.” surprise是名词,类似的还有to my disappointment令我失望的是,to my great joy令我开心的是,to my amazement令我惊叹的是
