句型详解

1.    A great way to help you remember something is to imagine a picture of it in your mind.

在这个句子中，有两处使用了动词不定式。第一个动词不定式作way的后置定语，修饰way，其作用相当于一个形容词；第二个动词不定式位于be动词之后，是句子的表语。

This is an exciting game to remember.  (to remember作game的定语)

My dream is to be an engineer．      (to be an engineer是表语)

 

  way 相关用法总结

1）way to do sth=,way of doing sth =,做某事的方式

2）do sth in this/that way, 以这种或者那种方式做某事

3）on the way to  在去什么的路上（当地点为home, here there时介词to省略）

4）in the way 挡路/by the way 顺便说一下

    

Imagine: 想象

名词形式为imagination 想象力；imagine+doing sth；想象做某事

 

2. A picture is worth a thousand words.一幅图片胜过千言万语。

   Be busy with sth/ be busy doing sth;  忙于某事、忙于做某事

   be worth doing sth  值得......

   The movie is worth watching

worth   adj.值得；有价值

①worth在句中一般作表语。当worth用作表语时，不能单独使用，其后通常接名词、Ving形式等，但不能接动词不定式。

②有时也可用作后置定语，如：

a place worth seeing（值得一看的地方）等。

常用的句式有：

a)       “主语+ be +worth+名词”。

This country is worth a visit.  这个国家值得游览。

His words are worth notice.   他的话值得引起注意。

I know you are busy,but it worth the time

 

b)       “主语+ be+ worth + Ving形式”。此时，句子的主语就是worth之后Ving形式的逻辑宾语。

This book is worth reading.     这本书值得一读。

He isn't worth getting angry with．(注意：Ving形式之后的介词不可省去。)

c)        “It(形式主语)+be十worth +Ving形式”。

 It isn't worth repairing the bike．

 Is it worth visiting the city? 

      一般来说，worth前面可用well，really，very much等词修饰，但不用very修饰。

    This is really worth trying．这确实值得一试。

    This film is well worth watching．这部电影很值得一看。

    请比较：

    (√)  This book is worth reading.

    (√)  It is worth reading this book.

    (√)  This book is well worth reading.

    (×)  Reading this book is worth.

    (×)  This book is worth being read.

    (×)  This book is very worth reading.

此外，worth还有如下用法：

      表示 “值（多少钱）” 的意思。其后主要接 数字类的词语。如：

    This wallet is worth 100yuan．

    This painting is worth a fortune．这幅画价值连城。

      表示“拥有……价值的财产”的意思。（了解即可）

    He is worth a million dollars．他拥有百万家产。

 

 

 

 

3.    For example, to remember the word ‘‘smiles”, we can imagine there is a ‘‘mile” between the first letter and the last letter.

本句中也使用了动词不定式to remember the word “smiles”，意为“为了记住‘smiles’这个单词”，作句子的目的状语。

To make a chocolate cake，we need some flour，eggs，butter and chocolate powder.

(to make a Chocolate cake解释了需要这些材料的目的，因此是目的状语。)

between…and…   ‘‘在……和……之间”。

    Li Ping sits between Wei Fang and Wang Hai. 

    Between the bookshop and the hospital is our school．

    You can come here between 8:00 and 9:00.   

4.    This makes it the longest word in the world.

 “make+宾语+名词” 的结构常用于表示“使……成为……”的意思。

    We made him captain of the football team. 我们推选他为足球队队长。

    I want to make teaching my future career.  我想把教书作为我的未来职业。

 

5.    A good method for remembering the spelling of a word is to make a short sentence with each letter of the word.

for remembering the spelling of a word是介词短语作后置定语的用法，用来修饰method，可以改写为动词不定式的形式，即a good method to remember the spelling of a word。又如：

The boy in blue is my younger brother．

(in blue修饰the boy，作后置定语。)

The book by my father is my favourite．我父亲写的这本书是我的最爱。

(by my father修饰the book，作后置定语。)

 

6. For example you may have trouble remembering the lists of steps in the water cycle..

 trouble  [c]．困难  近义词difficulty   n. 困难

Mary had trouble solving this difficult Maths problem．

trouble常用于以下结构或句型中：

a)       have trouble (in) doing sth    “做某事有困难”

We had no trouble finding his office.

b)      have trouble with   “有……问题”

He is having trouble with his teeth. 他正牙疼。

The man often has trouble with his wife. 

 

  Get sb into trouble  使某人陷入麻烦之中

  Be in trouble: 处于困境中

 

 

7.    However, it is easier to remember these steps if you understand how the water cycle works.

但是，如果你知道水循环是如何进行的，那你就能更容易地记住这些步骤。

句型： It is easy to do sth  “做某事是...的”   其中，it为形式主语， to do sth为真正主语。

e.g.: It is polite to remember others’ name.                   

【句型拓展】

It is adj. for sb, to do sth   该句型不含有“sb. is adj”的意思。

e.g.: It isn’t difficult for you to learn English if you spend time on it.

It is +adj. of sb. to do sth.  该句型含有“sb. is adj”的意思。本句型的形容词有：right, wrong, wise, kind, good, foolish, clever, nice...

e.g.: It is of you to speak to your parents like that.

本句中的work是动词，意为“运转；运行”。

    The phone is not working. 这部电话机坏了。

    How does the brain work? 大脑是如何运转的？

 

 

8.    Unless you get enough sleep every night, you will not remember things well.

     连词unless意为“除非...如果不...”，“除了....”，多引导一个否定意义的真实  条件句，有时也可引导非真实条件旬。unless引导条件句时.

  1）enough用作副同，充当形容词或副词修饰语，但必须后置。又如：  

  ①He walks slowly enough.

   enough用作形容词作定语时，可修饰可数名词或不可数名词，可放在被修饰的  名词前或后。如：  

  ①There are enough seats（seats enough）for them all. 

 

 

9. If you wish to get a good job, there are many important steps you should take.

  hope；wish  

两个词用作动词，均有“希望”的意思，都可接不定式作宾语，不接动词-ing形式，两个动词都可接宾语从句。  

  hope与wish都表示“希望”，两者不同之处在于：hope表示实现可能性大的希望，而wish只表示主观愿望，不考虑能否实现，常用于不能实现的场合，从句的谓语动词要用过去式（be用were）来表达现在或将来与事实相反的愿望。试比较：  

  I hope they can help us．我希望他们能来帮助我们。  

  I wish they could help us．我真希望他们能来帮助我们。  

wish后还可接形容词、不定式作宾语补足语，以及后接双宾语表示祝愿，而hope不能这样用。如：  

  I wish you to come here soon．我希望你尽快来这里。  

 

 

10. If you take a fish out of water, it dies

if 引导的条件状语从句，表示假设，其结果一定会发生，从句和主句时态都用一般现在时：

eg: If you heat ice, it turns into water.

 以下四个词均与“死”有关。

die是终止性动词，意为“死亡”，指生命的结束，强调动作。例如：  

His grandmother died two years  ago． 

dead意为“死的”、“无生命的”，常与be动词连用，表示死的状态。例如：  

He has been dead for two years． 

dying是die的现在分词，通常作形容词使用，表示“垂危”、“濒临死亡”之意。例如：   He is dying． 

death是die的名词，意为“死”、“死亡”。例如：  

It makes me very sad when I think of my little dog's death 

 

11.   Can you give me an example

    Give sb sth 给某人某物；也可改成give sth to sb

   give sb. a call  给……打电话    give back  归还，送回

   give out  分发，散发，用光，耗尽

   give away  泄密     give off  发出（光，烟，气）  give a hand  伸出援手
