Part1 I Warming Up &Reading

1、balanced diet 饮食不均衡

balance vt,平衡,权衡;n,天平,平衡

eg:Try to keep a balance between work and relaxation.

延伸:be out of balance 不平衡

Keep one' s balance 保持平衡

lose one' s balance 失去平衡

diet的用法:(1)n,日常饮食eg:Proper diet and exercise are both important for health.

be/go on a diet 照规定饮食,在节食

(2)v,节食eg:No sugar in my coffee,please. I'm dieting.

辨析diet,food

两者都可做“食物”讲,但diet指的是习惯的食物或规定的食物,特指维持健康的定量的或定制的食物,如病人的疗养饮食;food是一般的词语,凡是能吃能喝的东西都可以称为food。

2、feeling very frustrated 感到十分沮丧

feeling very frustrated 是现在分词短语作伴随状语。现在分词(短语)可以用作状语,修饰句子中由谓语表示的主要动作。这个状语可以表示动作发生的时间、原因、结果、条件、方式或表示主要动作发生的伴随情况,通常相当于一个状语从句或并列分句。一般说来,这种结构的逻辑主语就是句子的主语。伴随状语所表达的动作或状态是伴随着句子谓语动词的动作而发生的或存在的。如果现在分词的动作和谓语的动作同时发生,分词用一般式,有时其前可以加上连词while或when。

eg:He sat in the armchair,reading the newspaper.

Hearing the news,they all jumped with joy.

One day,while walking along the sands towards his boat,Crusoe saw in the sand the mark of a man' s foot. (有一天,克鲁索沿着沙滩走向他的船时,看见沙子上有一个人的脚印。)

练习:When we visited my old family home,memory came _______back.

A.flooding

B.to flood

C.flood

D.flooded

3、prepare vt,准备,筹备,常用结构如下:

To do

Prepare (sth)

for……eg:Please prepare the table for dinner. prepare oneself for……

for…He is preparing himself for the examination for Harvard. be/get prepared

to do…

4、ought(not)to do…(不)应该做……,表示一种道义上的责任,为情态动词的用法eg:You ought to respect your parents.

注意以下情态动词后接完成式的不同含义:

Ought to/should have done 本应该做……(却没做)

must have done 准是已经做过(推测)

can' t /couldn' t have done 不可能做过

may/might have done 或许已经做过

could have done 本来可以做(却未作)

would have done本来要做(却没能做)

needn' t have done 本来没必要做(却做了)

5、nothing ……better 为“否定词+比较级”结构,相当于最高级的用法

eg:I can' t agree more. (我非常同意)

There is nothing he likes more than a glass of beer .(他最喜欢喝啤酒。)

6、see his friend Li Chang hurrying.

这一句使用了see sb doing sth 的结构,其中doing 作宾语补足语,可接doing 作宾语补足语的动词有:五看(see、look at、watch、notice、observe),三使(have、make、get),二听(listen to、hear),一感觉(feel)。这些动词后也可接动词不定式(省略to)作宾语,区别是doing 强调动作正在进行或持续,do强调动作的全过程或结果。在主动语态中省略的to变被动语态要还原。

eg:I saw a chief stealing in' the store.

练习:Listen!Do you hear someone ________for help?

A.calling

B.call

C.to call

D.called

must have done是对过去发生的事情的肯定推测

eg:It must have rained last night.

as he always did 中as 作连词,引导方式状语从句

eg:Why didn' t you catch the last bus as I told you to?(你为什么不听我的话赶乘末班公共汽车呢?)

8、get/be/become tired of (doing)sth 意为“对(做)某事感到厌倦/厌烦

eg:If you get tired of working there,you can come to my company. (如果你不愿意在那儿工作了,你可以来我的公司工作。)

延伸:(1)tire vt 使疲倦tire out 使筋疲力尽
