★New words and expressions
☆catch(caught,caught) v.抓到
catch fish：抓鱼;catch thief:抓小偷
记住几个短语：
catch a cold:感冒;catch a bus:赶上车;catch one's breath:屏住呼吸;catch sight of=see;catch fire:着火;catch one's eyes:吸引某人注意力
☆fisherman n.钓鱼人，渔民

☆boot n.靴子
a pair of boots
☆waste n.浪费
v.You are wasting time.
n.a waste of
It is a waste of time/money/food.
☆realize v.意识到
eg:I realized that I was wrong.
实现：realize one's dream
●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
