定語(yǔ)從句講解：先行詞和關(guān)系詞的區(qū)別

　　定語(yǔ)從句講解：先行詞和關(guān)系詞的區(qū)別：

　　1)Whoever spits in public will be punished here.(“Whoever”可以用“anyone who”代替)

　　2)The parents will use what they have to send their son to technical school. (“what”可以用“all that”代替)

　　但這兩句句子已經(jīng)不是定語(yǔ)從句了，是名詞性從句。因?yàn)槎ㄕZ(yǔ)從句一定要有先行詞，而名詞性從句沒(méi)有。將“Whoever”、“what”分別用“Anyone who”、“all that”代替后，才是定語(yǔ)從句，先行詞分別是“Anyone”、“all”。

　　An invitation from her boss, ___came as a surprise.

　　A. it　B. that　C. which　D. he

　　答案C。

　　a選項(xiàng)it，使前后成為兩個(gè)句子，中間無(wú)連詞連接，語(yǔ)法錯(cuò)誤;b項(xiàng)that，此為非限定性從句，不能用“that”修飾;c選項(xiàng)which，which在從句中做主語(yǔ)，用來(lái)代指前面的這件事;d選項(xiàng)he;前半句中是her boss，所以不正確。

　　2)The weather turned out to be very good, ___ was more than we could expect.

　　A. what　B. which　C. that　D. it

　　答案B

　　A選項(xiàng)不能用來(lái)引導(dǎo)定語(yǔ)從句，C選項(xiàng)只能引導(dǎo)限定性定語(yǔ)從句，而D選項(xiàng)習(xí)慣上并不適用。

　　3)It rained hard yesterday, ____ prevented me from going to the park.[2]

　　A. that　B. which　C. as　D. it

　　答案B
