请问名词性从句中expect that 与 expect when的用法区别

except that...也是"除去……一点外"的意思,但应注意恰当地使用引导词.若从句句意和结构完整,只需用引导词that.例如:
　　1.The suit fitted him well ________ the colour was a little brighter.
　　A.except for B.except that
　　C.except when D.besides
　　析:Key:B.本题题意为"除色彩艳了一点儿外,这套衣服很适合他",从句the colour was a little brighter句意和结构完整,只需用引导词that,故选except that.
　　2.-Can you tell me all about the earthquake?
　　-Sorry,I know nothing about it ________ I read in the newspaper.
　　A.except B.except for
　　C.except what D.except that
　　析:Key:C.因从句中read为及物动词,且其后无宾语,故选except what.
　　3.Mr Green usually goes to work by bus ________ it rains.
　　A.besides B.except when
　　C.except what D.beside
　　析:Key:B.由于it rains为从句,故排除A、D,且rains为不及物动词,不需要宾语,故排除C.except when 意为"除了当……的时候".
