與that 在引導(dǎo)主語(yǔ)從句時(shí)的區(qū)別What 引導(dǎo)主語(yǔ)從句時(shí)在從句中充當(dāng)句子成分，如主語(yǔ)．賓語(yǔ)．表語(yǔ)，而that 則不然。例如： What you said yesterday is 、賓語(yǔ)從句名詞句用作賓語(yǔ)的從句叫賓語(yǔ)從句。引導(dǎo)賓語(yǔ)從句的關(guān)聯(lián)詞與引導(dǎo)主語(yǔ)從句表語(yǔ)從句的關(guān)聯(lián)詞大致一樣，在句中可以作謂語(yǔ)動(dòng)詞或介詞及非謂語(yǔ)動(dòng)詞的賓語(yǔ)。由連接詞that引導(dǎo)賓語(yǔ)從句時(shí)，that在句中不擔(dān)任任何成分，在口語(yǔ)或非正式的文體中常被省去，但如從句是并列句時(shí),第二個(gè)分句前的that不可省。例如：He has told me that he will go to Shanghai 。We must never think(that)we are good in everything while others are good in ，別人什么都不好。注意：在demand、order、suggest、decide、insist, desire, request, mand等表示要求、命令、建議、決定等意義的動(dòng)詞后，賓語(yǔ)從句常用“（should）+ 動(dòng)詞原形”。例如： I insist that she(should)do her work 。The mander ordered that troops(should)set off at 。，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等關(guān)聯(lián)詞引導(dǎo)的賓語(yǔ)從句相當(dāng)于特殊疑問(wèn)句，應(yīng)注意句子語(yǔ)序要用陳述語(yǔ)序。例如：I want to know what he has told 。She always thinks of how she can work 。She will give whoever needs help a warm ，她都會(huì)給予熱情的支持。，其主語(yǔ)和謂語(yǔ)的順序也不能顛倒，仍保持陳述句語(yǔ)序。此外，whether與if 在作“是否”的意思講時(shí)在下列情況下一般只能用whether，不用if： ；；；“or not”時(shí)；。例如：Whether there is life on the moon is an interesting 。The question is whether she should have a low opinion of the test?現(xiàn)在的問(wèn)題是她是否應(yīng)該有一個(gè)低意見(jiàn)的測(cè)試？Everything depends on whether we have enough 。I wonder whether he will e or 。Can you tell me whether to go or to stay? 你能否告訴我是去還是留？，當(dāng)主句動(dòng)詞是現(xiàn)在時(shí)，從句根據(jù)自身的句子情況，而使用不同時(shí)態(tài)。例如：he studies English every day.（從句用一般現(xiàn)在時(shí)）he studied English last term.（從句用一般過(guò)去時(shí)）I know(that)he will study English next year.（從句用一般將來(lái)時(shí)）he has studied English since 1998.（從句用現(xiàn)在完成時(shí)）當(dāng)主句動(dòng)詞是過(guò)去時(shí)態(tài)（could, would除外），從句則要用相應(yīng)的過(guò)去時(shí)態(tài)，如一般過(guò)去時(shí)，過(guò)去進(jìn)行時(shí)，過(guò)去將來(lái)時(shí)等；當(dāng)從句表示的是客觀真理，科學(xué)原理，自然現(xiàn)象，則從句仍用現(xiàn)在時(shí)態(tài)。例如：The teacher told us that Tom had left us for America．, believe, imagine, suppose等等動(dòng)詞引起的否定性賓語(yǔ)從句中，要把上述主句中的動(dòng)詞變?yōu)榉穸ㄊ?。即將從句中的否定形式移到主句中。例如?We don’t think you are 。I don’t believe he will do 。：，從句可用任意時(shí)態(tài)。，從句用過(guò)去某個(gè)時(shí)態(tài)。，從句是客觀真理時(shí)，只用一般現(xiàn)在時(shí)。從屬連詞：連接賓語(yǔ)從句的從屬連詞主要有that,if,而if和whether引導(dǎo)表示“是否” told me that he would go to the college the next don’t know if there will be a bus any knew whether he could pass the ：連接代
