情景导入
Collocations“搭配语”
阅读下面短文,体会句中黑体部分的用法。
I just hate getting to work in the morning.It ①takes such a long time to get to my office from my home because of the ②heavy traffic.Often I ③get stuck in a traffic jam and I really ④feel stressed out.Last year,I tried to ⑤share a car with my colleagues who live near me but it still took so long.Now I go to work by train.To be honest,I really ⑥worry about high levels of pollution.It seems every year it is getting worse.I can’t understand why people always drive cars,even for a short journey when they could walk.Even though in
recent years,the price of petrol goes up,people still ⑦make excuses to use their cars.If your journey is less than 30 minutes,I really think the obvious solution is to walk.It will help you ⑧keep fit and be good to the environment.
【语法感悟】
英语中的搭配语指的是某些单词可以和某些特定的单词组合在一起,而其他单词则不能与之搭配。常见的搭配形式有动词+名词,如短文中的　　　　　　　　;形容词+名词,如短文中的　　　　　。
①③④⑤⑥⑦⑧
②
语法精讲
Collocations“搭配语”指的是一种语言中,母语人士惯用的字和字的组合,听起来自然地道,也能快速、精确地传达意思。
1.日常生活
动词+名词
heat the soup把汤加热
do the laundry洗衣服
stain my shirt弄脏我的衬衫
water the flowers浇花
put on/apply lipstick擦口红(的动作)
2.生病就医
形容词+名词
就医时描述症状的用语通常都有固定搭配:
a runny nose流鼻涕
a phlegmy cough带痰的咳嗽
a scratchy throat喉咙痒
a mild fever轻微发烧
3.量词的搭配
a flock of birds/geese/sheep一群鸟/鹅/羊
a herd of elephants一群象
a swarm of bugs/insects一群昆虫
a grain of rice/salt一粒米/一粒盐
a cube of sugar一颗方糖
a bar of candy一块糖果
a head of cattle一头牛
注意:
(1)把搭配语看作单一的字块,而不是两三个单字;
例如,直接想“scratchy throat”,而不分开记“scratchy痒”和“throat喉咙”。
(2)比起分开记两个字,一次记住搭配语,学得更快。
例如,一次学会“behave properly”(表现得体),就学会了动词“behave”和副词“properly”。
