　　★　Which of these do you think is the mostuseful invention?

　　Which of these do you think is the most useful invention?你认为哪一种是最有用的发明。

　　Who do you think is over there?

　　你认为谁在那儿呢？

　　What do you think has happened?

　　你认为发生了什么事情了？

　　★　He was always trying out new ideas.

　　He was always trying out new ideas.他总是在试验一些新的想法。

　　Be always doing 表示总是在做着表达说话人的一种感情，如赞扬或者批评。例如：

　　My students are always studying hard.

　　我的学生总是在努力学习。

　　He is always making some mistakes.

　　他总是在犯一些错误。

　　★　His father saw him sitting on some eggs.

　　His father saw him sitting on some eggs.他父亲看到他正坐在一些鸡蛋上。

　　I heard someone singing in the classroom.

　　我听到有人在教室里唱歌。

　　★　The teacher could not answer all of them.

　　所有的学生没都来。

　　I didnt take all of them.

　　我没全拿走。

　　★　So he wanted to send Tom away from school.

　　So he wanted to send Tom away from school.所以他想让汤姆离开学校。

　　To send 是一动词不定式。作want 的宾语。动词不定式是原形动词前加一to.动词不定式在句中可作宾语或宾语补足语等。例如：

　　I want to buy some books.

　　我想买几本书。

　　He came here to help me.

　　他来帮助我。

　　I asked him to turn it down.

　　我让他把收音机关小。

　　★　She sent for a doctor.

　　Who sent you here?
