16.therebythereby解析：本句句意為“我們也正在污染海洋，殺死了魚(yú)類(lèi)，…剝奪了我們那無(wú)價(jià)的食物供應(yīng)?！憋@然，此空前后為因果關(guān)系，而且depriving前不能用so或其他表因果關(guān)系的連詞，而只能用介詞thereby。

17.whatwhat解析：顯然，此空后的句子應(yīng)為“obscure”的賓語(yǔ)從句，而“isbeingwritten”中缺主語(yǔ)，可做主句的賓語(yǔ)、從句的主語(yǔ)的只有what。

18.threatenthreaten解析：由33題解析可以知道此空一定為“威脅”之意。

19.whatwhat解析：這句話的意思是“這就是商家和賣(mài)者希望顧客們做的事情”，what引導(dǎo)的是一個(gè)表語(yǔ)從句，故答案為what。

20.dodo解析：解析見(jiàn)上題，為了避免與前面的know重復(fù)，這里可以換做do。故答案為do。

21.thatthat解析：此空后面的句子為suggesting的內(nèi)容，即應(yīng)為其賓語(yǔ)從句，所以此空處應(yīng)填引導(dǎo)賓語(yǔ)從句的詞，即that。

22.ofof解析：“對(duì)現(xiàn)實(shí)的了解”的英文表達(dá)是“theunderstandingofreality”，這里的介詞用of。故答案為of。

23.werewere解析：考查被動(dòng)語(yǔ)態(tài)的用法
