4．Jane ____ to school because she is sick．（　　）

	A．	isn't able come		B．	doesn't able come
	C．	isn't able to come

分析简不能来上学，因为她病了．

解答答案：C．考查否定句．句意"简不能来上学，因为她病了．"．be able to能，后跟动词原形．否定形式直接在be动词后加not，这里是在is后加not，缩写为isn't．答案是C，其它不正确．

点评考查否定句．通常是在be动词，情态动词后加not．一般现在时态，主语不是第三人称单数用don't，主语是第三人称单数用doesn't．一般过去时态用didn't．还有其它用法需要牢记．
