1.A “被忘在桌上”用被動！2, A clean在這里做形容詞，“干凈的”！make sth clean“使....干凈”如果選B,all the time就講不通了3，C do....with.....處理，應付！what做do的賓語

熱心網友

The key (was left) on the desk when I left.方法一：when后世過去時，所以排除BCD選項。方法二：key是物品所以用被動，選B。Our class room must be made (clean).make sth. adj.adj作賓補，所以用形容詞性的clean(be made adj/to do句型）。She didn't know （what) to do with the car which broke down halfway.What ...do with是“與...有關”的意思，故用what.

1.The key( A)on the desk when I go out.A.was left B.will be C.leaves D.has left鑰匙只能被忘記，所以用被動2.Our classroom must be made( A)all the time.A.clean B.to clean C.cleaning D.cleansclassroom是名詞，clean是形容詞，形容詞修飾名詞所以選第一個3.She didn't know( B)to do with the car which broke down halfway.A.when B.how C.what D.where首先要明白句子的大致意思，意思是在車子開到半路壞掉是該怎么做，所以選第二個

熱心網友

1.鑰匙是過去放在桌子上的,是人為動作,故本題應用一般過去時被動語態,選A.2。看句子“We must make our classroom clean all the time.＂想必應得到答案Ａ．此處clean作賓語補足語．３．"do with"為固定短語，后有賓語"the car",此句應為ＨＯＷ引導的方式狀語在句中做賓語從句，故選Ｂ．

熱心網友

同意以上的說法

熱心網友

1.The key(was left )on the desk when I go out.（被動語態）2.Our classroom must be made( clean )all the time.（使役結構）3.She didn't know( what)to do with the car which broke down halfway.do with 是處理的意思，在疑問句中用what 。

1.B when I go out 是現在時表將來，主句應用將來時2.A clean是adj3.C how to deal with what to do with

熱心網友

1.B A錯在時態不一致；B翻譯為“當我走時，會把鑰匙放在桌子上。”2.A 原因別人說了3.C what作賓語

熱心網友

答案是A A C,因為：１．應用被動語態，鑰匙被忘２．clean表示狀態３．what作do的賓語

熱心網友

應該是AAB AAB 啊

熱心網友

1.A 用被動 leave sth in/on 把某物留在在某處（鑰匙被留在/放在/忘在桌子上）這個動作先發生，然后才go out.2.A 用形容詞3.B I don't know how to do sth. 我不知道該怎么做.(是一個固定句式)這句的意思; 她不知道該怎么樣處理........
