8.Itcouldnothavebeena comfortable journey.
那不可能是一個(gè)舒適的旅行.

分析 那不可能是一個(gè)舒適的旅行.

解答 答案:could not have been.考查情態(tài)動(dòng)詞的have done的形式.could not have been表示"不可能是",是對(duì)過(guò)去的猜測(cè).

點(diǎn)評(píng) 考查漢譯英.
情態(tài)動(dòng)詞的have done的形式表示猜測(cè)的用法:
1.must have done
表示對(duì)過(guò)去某事的肯定猜測(cè),譯為:過(guò)去肯定做了某事.不存在 mustn't have done 的形式.其否定或疑問(wèn)形式須用 can(could) 來(lái)表示.例如:
Since the road is wet,it must have rained last night.既然路是濕的,那昨天晚上肯定下雨了.
2.may/might have done
may/might have done 表示"過(guò)去可能做了某事".may 比 might 表示的可能性在說(shuō)話人看來(lái)稍大些.may/might not have done表示"過(guò)去可能沒(méi)有做某事."例如:
I can't find my keys.I may/might have left them at the school yesterday.我找不到我的鑰匙了.我可能昨天把他們落在學(xué)校了.
3.can/could have done 表推測(cè)一般用在否定句和疑問(wèn)句中,表示不相信或懷疑的態(tài)度.
Can/Could he have passed the exam?他可能通過(guò)了考試嗎?
I think that he couldn't/can't have gone abroad.I saw him just now.我認(rèn)為他不可能出國(guó)了.我剛才還看見(jiàn)他了.

Dear Ted,
I'm sorry to hear that you are having difficulties adapting to the new environment and making friends.Let me share a personal experience with you.When I was eleven,my family moved and I was sent to another school.At that time,I also had a hard time.However,I did my best to make friends with my new classmates,and I gradually became popular with most of them.
Making friends is not difficult.First,make an impressive self-introduction in front of the class,so your classmates can get to know you better.Then,find a classmate with the same interest and get close to him.Last,try to join in the conversations when your classmates are chatting.
If you follow all these tips,you will definitely make new friends soon.
Yours,
Li Hua.
