1.----Who is knocking at the door
1.----Who is knocking at the door ,mary?-----It ( )Susan A must be B may be 2.nothing serious.You caught ( )cold .A a bit B abit of C little 3.Though some of the suits in the shop are nice .But they ( ) too much A cost B pay 说明原因

1、A ,这是情态动词的猜测虚拟可能性的用法,就一般人猜测的话会说,一定是什么什么,所以用must be 2、B,catch a cold中的cold此处为名词,只有a bit of才可用于此词组中修饰名词,构成catch a bit of a cold,表示“得了轻微感冒”,可以当成固定词组记住,貌似你后面丢了一个a,要不我就不会了 3、A,这是几个花费动词的用法区别,cost 的主语必须是物,pay和spend的主语必须是人,该题的they指的是衣服,所以用cost
