27.I was about to tell him the secret　　　　someone patted me on the shoulder.

A.as B.until

C.while D.when

解析：选D。考查be about to do...when...结构。句意为：我就要告诉他这个秘密，这时有人拍了一下我的肩。be about to do...when...表示“就要做某事，这时……”，为一习惯搭配，故选D项。

28.Lily got up at 6 o’clock　　　　，but she realized it was Sunday as soon as she prepared her school bag.

A.as possible B.as usual

C.at present D.at last

解析：选B。as possible“尽可能地……”;as usual“照常，跟往常一样”;at present“现在”;at last“最终”。根据句意“Lily跟往常一样6点起床，但是当她准备书包的时候她才意识到是星期天。”可知，应选B项。

29.—When was it that he　　　　to lend you some money?

—After he talked with his father，he told me that he could lend me money.

A.gave up B.made up his mind

C.took his mind D.changed his mind

解析：选D。由答语可知，他通过跟父亲谈话之后，才改变主意，答应借钱给“我”，故change one’s mind “某人改变主意”符合语境。give up“放弃”;make up one’s mind“下定决心”;无take one’s mind结构。

30.He is so kind a person that he takes a friendly attitude　　　　us.

A.of B.about

C.to D.on

解析：选C。take a friendly attitude to/toward sb.对某人采取友好的态度。

31.—Have you　　　　him to give up the job?

—Yes，I have.But he doesn’t listen to me.

A.persuaded B.suggested

C.agreed D.advised

解析：选D。由答语But he doesn’t listen to me推知，没有说服他放弃那份工作，故排除B项;suggest和agree后不能接不定式的复合结构。

32.They knew her very well.They had seen her　　　　up from childhood.

A.grow B.grew

C.growing D.to grow

解析：选A。句意为：他们对她非常了解。他们看着她从儿童时代长大。在see sb.do sth.句型中，省略to的动词不定式表示整个过程。
