Question

7．too many，all over the worldToo many trees have been cut down all over the world．

Answer 1

分析 全世界有太多的樹被砍．

解答 答案：Too many trees have been cut down all over the world．圖片上是樹被砍cut down，too many 太多，all over the world全世界，故造句全世界有太多的樹被砍．動(dòng)作發(fā)生在過去，對(duì)現(xiàn)在造成一定的影響，故用現(xiàn)在完成時(shí)have/has+過去分詞，主語too many trees復(fù)數(shù)，故have，主語是cut down的承受者，故用現(xiàn)在完成時(shí)的被動(dòng)語態(tài)have+been+過去分詞，cut的過去分詞是cut，后加地點(diǎn)狀語all over the world．故答案是Too many trees have been cut down all over the world．

點(diǎn)評(píng) 主動(dòng)語態(tài)表示主語為動(dòng)作的執(zhí)行者；被動(dòng)語態(tài)表示主語為動(dòng)作的承受者．現(xiàn)在完成時(shí)的被動(dòng)語態(tài)強(qiáng)調(diào)過去的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果，但主語為動(dòng)作的承受者，表示"…已經(jīng)被…"．如：
The new school has been set up．新學(xué)校已經(jīng)建成了．
