(2)as和which的选择 as和which都可用来引导非限制性定语从句，用来指代整个主句的内容。非限制性定语从句位于句末且as或which在从句中作主语宾语或表语时，两者常可互换。（但作主语时，最好是用which。） He failed in the exam, which/as was natural. He is an honest boy, which/as anybody can see. The man seemed a German, which/as in fact he was. 但要注意以下区别: 如果非限制性定语从句位于主句之前或位于主句之中时，只能用as。 As we have seen，oceans cover more than 70 percent of the earth. as在从句中作主语，后面常接行为动词的被动式;which在从句中作主语，后常接行为动词的主动式。 She has been late again，as was expected. 当从句和主句语意一致时用as，意为“正如”;反之用which。 The thief came again，as was expected. 小偷又来了，这是预料之中的。(语意一致) The elephant is like a snake，which is not right. 大象像一条蛇， 这是不对的。(语意不一致) as常用在 as often happens， as was pointed out， as was said above， as I remember， as I understand等结构中。【实战训练】Let the Ss use the knowledge of the grammar to finish the following exercises.1. _is known to everybody, the moon travels round the earth once every month.A.

Which答案：B解题思路： 与上一小题相比，句中多了is that，所以这是一个主语从句，只能选择连接代词作句子的主语。所以B项正确。3. Look out! Dont get too close to the house_ roof is under repair. A. whose B. which C. of which D. what答案：A解题思路： house与roof之间存在所属关系，所以应用whose。4. Look out! Dont get too close to the house_ the roof is under repair.
