(3)except后接名词、代词、动名词和动词原形，这时except=but；但except后跟副词、介词短语时，不能用but代替。如：The window is never open except in summer.
这扇窗户从来不开，除夏季外。He did nothing except/ but clean the house.
他只是打扫了房子。 2. Besides, not everything we read on the Internet is true or good for us.另外，我们在网上看到的东西并不都是真实的、有益的。 1b 2. Complete the following diagram. computers usageproblemwork daily life____________________________ of a spaceship.
