My little sister          me into buying this book.

wanted

advised

persuaded

told

考查动词词义辨析。句意：我的小妹妹说服我买了这本书。A. want想，想要；B.advised 建议；C. persuaded说服，劝服；D.told告诉。want  sb to do sth想要某人做某事；advise sb to do sth 建议某人做某事；persuade sb into doing sth 劝服某人做某事；tell sb to do sth告诉某人做某事。故选C项。

---Have you moved into        new office?

---No, the building is under          construction.

a; the

the; /

/; the

/; /

考查冠词。--你搬到新办公室了吗？--没有，大楼正在建设中。new office 谈话的双方都知道，所以是特指，需要用定冠词the,第二句under construction 指“正在建设中”，是固定搭配。故选B项。

When Huawei P20 came out,         people couldn't wait to buy one in our town.

thousand

thousands

thousand of

thousands of

考查数词的用法。句意：当华为P20上市时，成千上万的人迫不及待的想在我们镇上买一台。thousnad意思是“千”，其前有具体数词修饰时，用其单数形式；当其前没有具体数词修饰时，用其复数形式，且与of 连用，thousands of“成千上万的”，这里没有具体数词修饰。故选D项。

---Miss Yuan，you promised！

---Well，______.But it was you broke your word first.

so was I

so did I

so I was

so I did

考查强调句。句意：袁女士，你承诺过的！噢，我确实如此。但是是你先失言的。A和B是一类回答，C和D是一类回答。当别人说他自己怎么样，而你有跟他同样的情况时，用AB这样的形式回答。当别人说你怎么样，而你自己也确实是他说的那样时，用CD回答。至于用be动词还是do要根据具体语句定，谓语是be时就用be的相应形式，谓语是实意动词时就用do的相应形式。根据句意，故选D。

A study shows the students who are engaged in after-school  activities are happier than        who are not.

ones

those

these

them

考查代词。句意：一项研究表明，参加课外活动的学生比不参加课外活动的学生更开心。空格处代词与the students是对应关系，可以用the ones 或者those替代。“them”指代前面提到的复数名词，不能与the students形成对应关系，“these”一般不用定语从句修饰。故选B项。
