1.She was so surprised that her mother _was waiting_(等待)for her.
-wait for sb 等某人,that后從句要和主句時(shí)態(tài)符合,所以用過(guò)去（進(jìn)行）時(shí)
2.Chinese culture is not so easy _to understand_(understand)
-so + 形容詞 + to + 動(dòng)詞
-這句話：中國(guó)文化不是那么容易理解的.
3.sometimes it isn't easy _to be_ a good teacher at school.
-be + 形容詞 + to do sth,做某事是怎樣的.
4.there are three girls waiting_to cross_(cross)a busy street.
-wait to do sth ,cross 是動(dòng)詞,穿過(guò)
5.Usually it is difficult_to be_(be) a good leader there.
-同3
6.Can you tell me_B_with the mobile phone.
A.what's the matter
B.what the matter is
C.before he will come back
D.until he comes back
因?yàn)榭崭裉幍膬?nèi)容是tell的賓語(yǔ),所以從句要用陳述句的語(yǔ)序
-------------------------------------------------
我堅(jiān)持我的觀點(diǎn).
他給的答案僅僅是參考..而不能說(shuō)是"正確"答案..(我們老師說(shuō)的)
要敢于質(zhì)疑啊
如果題1用waiting,這個(gè)句子就不對(duì)了.因?yàn)榭崭裉幦钡氖侵^語(yǔ),waiting怎么能做謂語(yǔ)呢?如果是進(jìn)行時(shí),要有助動(dòng)詞be啊.
第3和5題,都是 it is adj.to do sth 這樣的一個(gè)句式,
我可以肯定,你也可以從書(shū)上找到類似的句式.
但是從沒(méi)見(jiàn)過(guò) it is adj.doing sth
還有第6題,空格處如果是tell的賓語(yǔ),賓語(yǔ)如果是句子,那這個(gè)句子就要用陳述的語(yǔ)序.A是疑問(wèn)的語(yǔ)序,倒裝過(guò)了;B是陳述的,所以選.
然而一開(kāi)始我也忘記考慮了...如果空格處是狀語(yǔ)...C和D都是狀語(yǔ),C錯(cuò)在will,應(yīng)該改成before he comes back;D也是錯(cuò)的,因?yàn)閠ell是瞬間的動(dòng)詞,一瞬間的事情是不能延續(xù)到he comes back的.(或說(shuō)until帶的時(shí)間狀語(yǔ)是一段時(shí)間的,而不是瞬間的)
