常考题型及答题技巧
(一)时态与句型结构
1. 一般将来时(will/shall + 动词原形)
教材重点:Unit 1 “Be going to” 与 “will” 的用法对比
句型:
肯定句:We will visit the farm next week.
疑问句:Will you study science tomorrow?(Yes, I will./No, I won’t.)
考点:will 后接动词原形,否定式为 “will not/won’t”。
(二)固定句型与功能句
1.提建议句型
Why not do sth.? / Why don’t you do sth.?(为什么不……?)
You’d better do sth.(你最好……)
Let’s do sth.(让我们……)
示例:Why not p a tree this weekend?(plant)
2.感叹句
What + (a/an) + 形容词 + 名词 + 主语 + 谓语!
How + 形容词 / 副词 + 主语 + 谓语!
示例:W a nice day it is!(What) / H happy they are!(How)
3.There be 句型
There is/are + 名词 + 地点状语
考点:就近原则(be 动词与最近的名词单复数一致)
示例:There a some water in the bottle.(is) / There a two books on the desk.(are)
二、答题技巧分步攻略
(一)句型题解题三步法
1.识别句型类型,定位考点
看到 “tomorrow”→将来时(will + 动词原形);
2.分析句子成分,补全结构
缺主语:补名词 / 代词(如:S is my best friend.→She);
缺谓语:根据时态补动词(如:They p football yesterday.→played);
缺表语:补形容词(如:The food tastes d.→delicious)。
3.语法校验,确保形式正确
时态:过去时→动词加 - ed(规则)或不规则变化;
单复数:There is + 单数 / 不可数,There are + 复数;
(二)高频句型突破技巧
1.利用标志词快速判断
将来时标志:tomorrow, next week, in the future;
例:He will go to the park n Sunday.(next)
2.句型转换公式记忆
否定句:be 动词 / 情态动词后加 not;实义动词前加 don’t/doesn’t/didn’t
(例:He is happy.→He isn’t happy. / He likes reading.→He doesn’t like reading.)
一般疑问句:be 动词 / 情态动词提前;实义动词前加 Do/Does/Did
(例:They play football.→Do they play football?)
对划线部分提问:特殊疑问词(what, where, when, how)+ 一般疑问句
(例:She eats apples.→What does she eat?)
3.固定句型搭配速记
It’s time to do sth.(该做某事)→It’s time to g to school.(go)
be good at doing sth.(擅长做某事)→He is good at s.(swimming)
spend...(in) doing sth.(花费…… 做某事)→She spends two hours r books.(reading)
(三)易错点避坑指南
There be 句型单复数错误:
错误:There are a book on the desk.(a book 单数→is)
