1.C FOR OUR..那么后面应该是我们的什么,所以是个名词.STUDY本身就有名词的意思,所以不会是STUDYING.STUDIED过去分词也不可能.所以studies复数形式
2.D lily has not visited完成时,没有去过很多地方.neither是在表示否的的'也'里面用的.如果是肯定,那么so.'s省略的是HAS,如果要是IS的话,又有VISIT,一句话里面就有两个动词了,英语语法大忌
3.B 倒装固定句式.ONLY提前的强调句,主句谓语倒装
4.WORRIED.变得慌张了.WORRIED形容词.GET+ADJ.系表结构.东西变凉了.GET COLD.后面加形容词.
5.C.which引导一句话.主系表结构,又有ABOUT,那么BE动词后面应该是个形容词而不是名词,大概那么长.She is a 6-year-old girl一样,六岁的做形容词起修饰作用.连字符连起来的都用单数
6.D.同3题.你被允许进入,被动句.
7.be required被要求
8.is grown被动句
