★Text

One man in a boat
Fishing is my favourite sport.I often fish for hours without catching anything.But this does not worry me.Some fisherman are unlucky.Instead of catching fish,they catch old boots and rubbish.I am even less lucky.I never catch anything-not even old boots.After having spent whole morning on the river,I always go home with an empty bay.'You must give up fishing!'my friends say.'It's a waste of time.'But they don't realize one important thing.I'm not really interested in fishing.I am only interested in sitting in a boat and doing nothing at all!

●本课的重点是-ing形式

☆fish n.鱼：一般情况下作为不可数名词用
eg:I have bought some fish.
在表示种类时为可数名词
eg:There are a lot of fishes in the sea.

v.钓鱼-->n.fishing
主语通常由名词和代词充当。动词+ing就变成名词词性
如:eat->eating;read->reading

☆...without catching anything.
without(prep),介词后面一定要加宾语
同样，动词+ing变为名词做宾语

without doing作为状语而出现，表示结果状语
eg:He went out without saying any words.
Without asking for money,the boy went to school.
without后面的动作由主语来做

☆instead of后面的词一定是没有做的，可以放在主句后面
与without比较：
without强调没有做某事
instead of强调这件事没做成而做成了另外一件事（有“代替”的含义）
翻译成：我原准备做……但是后来做了……
eg:I go to school instead of staying at home.
I bought books instead of buying dresses.

☆v.worry sb:宾语为主语而感到担心
adj.be worried about:主语为宾语而感到担心

☆less+原级
A is less...than B.“不如”

☆after
after+从句（连词）从句的主语必须是主句的主语才能换成下面一种形式
after+名词/动词ing形式
eg:After I go to school,I learned a lot of knowledge.
=After going to school,I learned a lot of knowledge.(主语都是I)

☆give up doing=stop doing:放弃做某事
give up smoking:戒烟

☆be keen on,be fond of,be interested in,enjoy+doing:喜欢

☆be up to,be capable of:胜任
