教学目标:学会运用used to句型谈论自己与他人的过去习惯、爱好及经常做的事情。
主要知识点:
1. use v.& n. 使用;用途 →adj useful 有用的useless 无用的。
use sth. to do sth . 用某物做某事
farmers use horses to do the farm work . 农民用马干农活。
used to do sth . 过去常常;过去曾经
i used to sleep in class → i didn’t use to sleep in class .
i usedn’t to sleep in class .
be used to(介词)+ n. /pron. /doing 习惯于
i am used to getting up early .
be used to do sth / be used for doing sth 被用来做…
the knife is used to cut apples .
the knife is used for cutting apples .
be used as 被用作… ‘介词as表示“作为…”;后常接名词。
english is used as a foreign language in china .
be used by 被…使用 ;介词by后面常接动作的执行者
the car is used by my uncle .
例 --how does jack usually go to school ?
---he __ride a bike ;but now he __there to lose weight .
a .used to ; is used to walk b .was used to ; is used to walking
c .was used to ;is used to walk d .used to ;is used to walking
解析:根据题意可知;此题考查used to do(过去常常做某事);be used to doing(习惯做某事);故此题选d. 而be used to do 意为“被用来做…”
2. 反意疑问句。
①肯定陈述句+否定提问如:lily is a student; isn’t she?
lily will go to china; won’t she?
②否定陈述句+肯定提问如:
she doesn’ from china; does she?
you h**en’t finished homework; h**e you?
③提问部分用代词而不用名词 lily is a student; isn’t she?
④陈述句中含有否定意义的词;如:little; few; never; nothing; hardly等。其反意疑问句用肯定式。 如:
he knows little english; does he? 他一点也不懂英语;不是吗?
they hardly understood it; did they?他们几乎不明白;不是吗?
注:反意疑问句的答语。
如果反意疑问句中的陈述部分为肯定句时;用“yes+肯定结构”作为肯定回答;用“no+否定结构”作为否定回答。
---he enjoys singing ; doesn’t he? 他喜欢唱歌;是吗?
---yes; he does. /no; he doesn’t. 是的;他喜欢。/不;他不喜欢。
如果反意疑问句中的陈述部分为否定句时;yes译为“不”;no译为“是”
---you didn’t go to school ;did you ? 你没有去上学;是吗?
---yes; i did . no; i didn’t不;我去了。/ 是的;我没去。
例:--jim had nothing for breakfast this morning; _
he got up too late .
a .had he; yes b .hadn’t he; yes c .did he; no d .didn’t he; no
解析:由nothing可知陈述部分为否定句;故附加疑问部分应用肯定形式;故排除b、d;本句时态为一般过去时;应用助动词did .故选c
3. help v.& n. 帮助 → adj. helpful 有帮助的。
相关短语及句型:
help sb. with sth. 在……方面帮助……
help oneself to 随便吃……
help sb. out 帮助某人解决困难。
help sb. (to ) do sth .帮助某人做某事。
with the help of sb = with sb’s help 在……的帮助下。
4. what’s sb like ? 意为“……是什么样的人?” 多用于提问人的性格、品质等;也可用于提问人的相貌。
what’s alice like ?
she is quiet and a little shy .
注:what does sb look like?用来提问人的长相、外貌;意为“….长得什么样?”
what does tom look like ?
he has short hair .
5. enough副词;意为“足够的;充分的”;用来修饰形容词或副词;一般置于被修饰词之后。
he runs quickly enough .
形容词;意为“足够的;充分的”;在句中作定语修饰名词;名词既可放前也可放后。
we h**e enough time to do our homework .
adj /adv +enough to do sth 意为“足够…可以做某事”
the boy is old enough to go to school .
6. it has been + 一段时间 +since + 过去式的陈述句 “自从……已经多长时间了”;还可表示为“it is +一段时间+since+从句”
it has been four years since i worked in the school .
注:since此处用作连词;意为“自从;自从…以来”。主句常用完成时;且动词需用延续性动词。since后接从句;该从句用一般过去时态。
she has taught english since i came to this school .
since 还可用作介词;意为“自从…以来”;后接表示时间点的词。
he has worked there since 10 years ago .
例:my uncle has been taught in this school __he was twenty years old .
a .since b .for c .until d .after
解析:since 引导的从句是现在完成时的标志之一。句意为“自从他20岁起;我叔叔就一直在这所学校里教学。”
7. from time to time =sometimes 有时;时常一般现在时的标志。
8.turn 变成多用于在颜色或性质等方面的变化;强调变化的结果。
变得;成为通常指身份、职位的变化;强调变化的过程已完成。
get 变得多用于口语;表示一种变化过程;强调“渐渐变得”;其后常接形容词比较级。
the man turned blue with fear . 那个人吓得脸色发青。
she became an english teacher .
in winter ; the days get shorter .
9. see sb. do sth . 看见某人做了某事指整个过程即:指动作经常发生或刚刚完成。
see sb. doing sth .看见某人正在做某事。 指当时正在进行的动作。
i saw him playing football on the playground .
i saw her run into the room .
例:when i came into the school ; i saw some boys basketball on the playground .
a play b . playing c plays d to play
解析:此题考查see sb do sth 和see sb doing sth 的区别;句意为“当我进学校时;我看见一些男孩正在踢足球”;故选b
类似用法的单词还有:
hear sb. do sth. /hear sb. doing sth .
watch sb. do sth . watch sb doing sth .
10. 19-year-old 十九岁的;这是由“数词--名词--形容词”构成的复合形容词;其中间用连字符连接;其中的名词必须用单数。
