1.困扰的是we.he是主动的,所以是was confusing.他说的话使we困扰,we是被动的.所以是was confused.
2.虽然我水平也有限,但是我强烈感觉在necessary前面应该少了个is.这句话最完整的应该是I thought (that) __it is_necessary __for_him to tell his father everything.从句,括号里的that可以直接省略掉.就算是选项里有that,也一定得有it在后面,对于从句来说,it才是主语.for sb,of doing sth.
3.look up查找,look for寻找,pick out去掉,pick up捡起
4.定语从句.前后两个都是that可以,都是which的话应该也没问题
5.team单数,所以是consists.
6.make up组成.girls,所以用make就可以
7、spread原型、过去式一样.有显示、展示的意思,主动语态
8.考词义.witness目击,证明.contribute增加,起促成作用.consist构成,包括.relate联系
9.make it a rule.记住就成.习惯说法,个人觉得没的解释
10.avoid doing.排除a和c.被惩罚,被动语态,be punished
11.turn to转向.
depend on依靠.
ask for请求.(如果用这个的话,应该是i'll ask for your help)
look after注视,照顾.
