自主研习
【例1】I feel ill.我生病了。(P26)
点拨:ill 形容词,作"不健康的;有病的"讲时,一般用作表语,不作定语。如:
She was badly ill.
她病得很厉害。
ill作"坏的;有害的"讲时,只能用于名词前作定语。如:
I think he is an ill man.
我认为他是一个坏人。
【例2】Since Friday.从周五开始。(P26)
点拨:since介词,意为"自……以来",其后接一个表示过去时间点的名词、代词或动词﹣ing形式,常用于现在完成时。如:
He has been seriously ill since last month.
他从上个月开始就病得很重。
We haven't seen each other since finishing school.
自从毕业后我们就一直未见过面。
辨析:since和for
since
作介词,后跟时间点,用来说明动作起始的时间。
for
作介词,后跟时间段,用来说明动作延续的时间长度。
Lingling has lived in Hainan since 10 years ago.=Lingling has lived in Hainan for 10 years.
玲玲在海南住了10年了。
拓展:since用作连词时,意为"自……以来",引导时间状语从句。从句中常用一般过去时,主句中常用现在完成时。如:
Betty has lived here since she became a teacher.贝蒂自从当了老师就住在这里。
注意:在英式英语中,可以用it is +时间+since...,而在美式英语中,通常用it has been+时间+since...如:
It is(英)/has been(美)four years since Mary moved here.
玛丽搬到这里四年了。
【例3】Have you caught a cold 你感冒了吗?(P26)
点拨: catch a cold 意为"感冒"。catch 也可以换成have,即 have a cold。其中 cold 为可数名词。如:That old man caught/had a bad cold.那位老人得了重感冒。
拓展:catch在此类短语中有"患上"的意思。表示患上某种"病症;症状",常用"catch + a(n) +名词",如:catch a fever发烧,catch a cough 咳嗽,catch a headache头痛。
辨析:catch a cold和have a cold
catch a cold
为非延续性动词短语,用于肯定句中,其后不能直接跟时间段。
have a cold
为延续性动词短语,其后能直接跟时间段。
I started to catch a cold yesterday.
我昨天开始感冒了。
I have had a cold since three days ago.我已经感冒三天了。
【例4】It can be very harmful to your health. 这对你的健康非常不好。(P26)
点拨:(1)be harmful to意为"对……有害",其同义短语有 be bad for 和 do harm to。如:
Eating too much fast food is harmful to our health.=Eating too much fast food is bad
