考题分析
】
I need one more stamp
before my collection______.
A. has completed
B. completes C. has been completed D. is
completed
析:
complete
是及物动词,“邮集”是被人完成的,须
从表被动意的C、D中选择。又因
before
等引导的时间状语从句中谓语要用一般现在时表
将来,所以此题答案为D。

at

【
考题分析
】
——Do you
like the material?
——Yes, it______ very
soft.
A. is feeling B. felt C.
feels D. is felt
析:观察题干,空白线后无宾语,可知
feel<
br>是不及物动词,表“(某物)摸起来…”意思,是连
系动词,不能用于被动式,也不用进行时。根
据此题对话情景,是指某种材料的常规特性,要
用一般现在时,不能用过去时,故答案为C。feel作
“感觉”、“认为”、“摸”等意时是及物动词,
可带宾语,有时态,语态等变化。
