    1. Unless you have a map, you will get lost easily.


    (1) unless 除非

    He’ll go there unless it rains.


    He is sure to come unless he has some urgent work to do at home.


    (2) get lost迷路

    I gave you a map so you wouldn’t get lost.


    The little child got lost while his parents doing shopping.


    2. The emperors of the Ming and Qing dynasties used to live here.


    “主语+used to+动词原形+其它”这个句型结构表示过去的习惯,暗示现在已无此习惯。


    其否定形式是主语+didn’t use to+动原

    问句形式为:Did+主语+use to+…?

    反意疑问句:主语+used to+…,did+主语?

    和used to 相关的其它句型:

    get / be used to doing 习惯于做……

    be used for doing被用来

    I used to be afraid of the dark.


    Mary used to be short.


    You used to have long hair, didn’t you?


    I used to live in Shanghai.


    3.You will be attracted by the beautiful design of the buildings, and the clothes and furniture that the emperors used in the past.

    (1) attract 吸引

    We were attracted by the display of lights.


    The fire attracted significant coverage from the media.

    English was spoken here in the past.

    be filled with 充满了……,我们也常用fill(in)…with…。例如:

    Please fill in the blanks with right verb forms.


    The cup is filled with water.


    另外,be full of 也是“充满”的意思。例如:

    The bag is filled with apples. = The bag is full of apples.


    5. Every day many tourists gather here early in the morning so that they can watch the raising of the national flag.


    (1) so that“以便于……,为了……”。引导目的状语从句,意为“以便,使能够”,从句中的谓语动词常由can, could, may或might+实意动词构成。例如:

    We will get up early tomorrow so that we can catch the early bus.


    We bought another TV set so that each of us could have his own.


    I’ll speak slowly so that you can understand me.


    注意:so that 和so…that 的区别

    so that作 “以致于” 讲时, 相当于so…that…句型中that的含义。作“为了……”讲就与so…that…不同了。例如:

    I got up very early yesterday so that I could get to school first.

    昨天我起的很早, 为了第一个到校。

    It is raining heavily so that we are late for school. = It is raining so heavily that we are late for school.

    English is spoken in many countries all over the world.


    7. You can experience its beauty and greatness although it is very tiring to climb it step by step.

    He has not enough experience for the position.


    A man of your experience ought to do well.



    He experienced all sorts of difficulties and hardships.


    He is much experienced in teaching.


    8. You cannot imagine how amazing they are unless you see them with your own eyes.


    imagine + n. / doing

    Integrated Skills

    1. arrive in Tokyo



    It is said that he will arrive tomorrow.


    He was among the first to arrive.


    arrive一般和介词in, at搭配。at后一般跟小地点, in后跟大地点。例如:

    where 在此句中引导地点状语从句


    I’ll go where work conditions are difficult.


    I found the key where I had left it.


    Where there is a will, there is a way.


    Wherever you are, you should work for the people heart and soul.


    4. There are hundreds of shops in Myeongdong Shopping District.

    hundreds of 表示“数以百计的”。它与thousands of, millions of 等一样,主要用来强调“多”,它们只能表示“大约多至”,“数以……计”,不可表示明确的数目,前面切不可加表示具体概念的数词。但是,这类词组前可以加一些表示不确定数目的修饰语。例如:

    These things were all invented hundreds years ago.


    Thousands of people went to watch the football match.


    Many hundreds of buildings are being built.


    Several millions of trees are planted in our country every year.


    注意:hundred, thousand, million 等在表示具体概念的数字时,后面都不可再加“-s”,前面需加表具体数量的词。例如:

    There are more than eight hundred students in our school.


    At the beginning of the twentieth century, the world’s population was about 1,700 million.

    spend money on sth.

    spend sth. on sth. / in doing sth.

    They always spend a lot of time in explaining a plan.



    ①spend 的主语必须是人,宾语可以是钱、精力、时间等,用法如下:

    spend…on (for)+名词

    He spends much money on books.


    spend …(in) doing sth.

    Every morning he spends half an hour in reading English.



    The book costs him one dollar.


    Making experiments like this costs much time and labor.



    常用 “It takes(took) sb. some time to do sth.” 结构。

    It took me ten minutes to go to the post office.


    Painting the picture took me all week.


    ④pay 意思是“支付”,作为及物动词,宾语可以是人、钱。例如:

    He paid the taxi and hurried to the station.


    They had to pay two hundred francs.


    pay for 的宾语为物、事。for 表示支付的原因。

    You’ll have to pay me ten dollars a week for your meals.



    1. I wish people could walk or ride bicycles instead of driving cars unless it is really necessary.

    (1) wish意为“想要,需要,渴望,希望,但愿”,后接名词性从句,从句中的动词用虚拟语气形式。

    I wish I could fly like a bird.


    I really wish I could read some funny stories.


    I wish to come tomorrow.



    I send you my best wishes.




    ①hope与wish后都可接动词不定式,但wish后还可接“sb. + to do sth. ”的结构,而hope则不可以。如果用hope表达主语希望别人做某事时,后面要接宾语从句。例如:

    Jim hopes to get a baby horse for his birthday.


    I hope to have a look at your new car.


    The little girl hopes her mother will come home from work earlier today.


    My aunt wishes to find her lost watch somewhere.


    The little girl wishes her mother to come home from work earlier every day.



    We hope to visit this place again.


    We hoped to save more money.


    I’m hoping that you will accept my offer.


    He wishes to go to the moon now.


    I wish I could make no mistakes in the exams without any difficulty.


    (2) instead of“代替,而不是”

    instead of 是介词短语,其后跟名词、代词、动名词或介词短语作其宾语,例如:

    He went there to gain money instead of to spend money.


    He likes playing football instead of basketball.


    My father watched TV last night instead of seeing a movie.


    You should join a queue instead of jumping the queue.


    辨析:instead of与instead

    ①instead of后面的事物往往是不做的,没有的。后面接名词,代词或动词-ing形式。

    I stayed at home all day instead of going to work.


    Let’s play cards instead of watching TV.



    I didn’t go to work. Instead, I stayed at home all day.


    Our car has something wrong. Shall we go there by bus instead?


    We’ve no coffee. Would you like tea instead?


    2. Unless I learn to cook, I will not be able to enjoy the tasty Chinese food when I go back to the USA.

    be able to “能,可以”

    It is hoped that you’ll be able to attend the concert.


    辨析:can与be able to

    ①can和be able to都可表示“能,可以”,意思上相同。但can只有现在式和过去式(could)两种形式。如需用其它时态,则用be able to代替,例如:

    He can still be alive.


    He can’t be poor.


    He has not been able to finish the work in time.


    I’ll be able to see you tomorrow.


    ②如果我们要表示一个动作成功地完成了,那么必须用was able to,而不能用could。例如:

    He was able to leave Europe before the war began.


    He was able to go to Paris yesterday and enjoyed himself very much.


    ③在否定句中could与be able to两者意思一样。例如:

    I could not / was not able to swim to the other side of the river.


    ④can / could不应与be able to同时使用。
