Unit3 A visit to Garden City 语言点及练习（含答案）

2022学年牛津上海版英语七年级第二学期语言点及练习unit3
一、语言点整理
1. (1)She has been a teacher since 1997 自1997年以来，她一直是一名教师。
(2)She has been a teacher for quite a few years. 她当教师已经好些年了。
since 是现在完成时的一个标志词
请注意，since后接“一个时间点”，如：since last Monday/three o’clock等。Since 还可以引导时间状语从句，一般来说从句要使用过去时。如: He has been a teacher since he left the university.
for后则接“一段时间”，如：for two hours/months等，又如：Aunt Judy and Uncle Jack have lived in Los Angeles for six years.
现在完成时基本结构： have/ has done(动词的过去分词)。
在现在完成时的句子中如果有since/for 引导的时间状语，句子中的谓语就表示持续的动作涵义，必须使用持续性动词，而不可使用短暂性动词。
Eg: 1) I have been in the club for three years. √
2) I have joined the club for three years. X (join是短暂性动词)
对since/for引导的时间状语提问要使用How long
She has been a teacher for a quite a few years. 她当老师有好几年了？
How long has she been a teacher 她当老师多久了？
2. Aunt Betty works in a company in Beijing, doesn’t she 贝蒂姨妈在北京一家公司工作，对吗？
反义疑问句结构：陈述句，+助动词/be动词/情态动词(肯or否) +主语的人称代词
陈述部分为肯定，疑问部分为否定；陈述句部分为否定，那么疑问部分必须为肯定
在反义疑问句中陈述部分的动词和时态必须与疑问部分的动词和时态相匹配
疑问部分只能使用人称代词，如you, he,we, they等，不能使用名字或名词，如Tom, her aunt等都是不行的。
当陈述部分含有有否定词如never, no, few, little hardly seldom等时，陈述部分为否定句，这时疑问部分必须为肯定
当陈述部分含有由un-, im-, in-, dis-等否定意义的前缀构成的词语时，陈述部分还是肯定句，后面的疑问部分仍然要使用否定形式。Your father is unhappy, isn’t he
所有的祈使句，包括Let us…, 疑问部分用 will you
Let’s … 疑问部分用shall we
反义疑问句回答：根据实际情况作答；回答方式同一般疑问句；
3. A farmer grows vegetables in fields. 农民在田地里种蔬菜。
（1）句中的grow 做v. 意为：种植。
（2）曾在6B出现的grow bigger，grow意为“长大；
4. A watch is used for telling the time. 手表是用来了解时间的。
当一个物做主语时，常用be used for doing 可用于表示“（某物）被用来……”也可以是：be used to do
区别used to do 过去常常做某事；be used to doing 习惯于做某事
tell the time 报时
5. quite a few years = many years 许多年 quite表示相当，十分，和rather/very 意义比较接近
6. He catches thieves and help keep the city safe. 他抓小偷，保持城市的安全。
Keep sb./ sth. + adj: 使…保持某种状态
Help sb. (to) do/ help sb. With sth. 帮助某人做某事
