2018-2019年人教版八年级英语上册Unit3SectionB词汇点睛
八年级上册英语期末高频考点专题突破(人教版)Unit3 SectionB
Unit3 SectionB知识讲解1. is talented in music.be talented in指＂在……方面有天赋＂，后接名词或动名词。
2. likes to do the same things as me＂the same +名词+ as＂意为＂……和……一样＂。
3. makes me laughmake sb. do sth.使某人做某事。
使役动词make和感官动词see, hear, listen to, look at, watch, notice 等都接不带to的不定式作宾补。
help后的不定式可带to，也可不带to。
4. I’m so shy so it’s not easy for me to make friends.(1)It is+形容词/名词+(for sb. +) to do sth.，it是形式主语，动词不定式to do sth.是真正的主语。
sb.为宾格代词或名词，因为主语太长，为了使句子保持平衡，习惯上把真正的主语放在后面，这样就避免了句子头重脚轻。
(2)＂It is+形容词+ (for sb. +) to do sth.＂相当于＂It’s+形容词+that 从句＂。
5. But I think friends are like books —you don’t need a lot of them as long as they’re good. as long as＂只要；既然＂，表示条件，意思是＂只要＂，引导条件状语从句。
6. My best friend is similar to Larry because she’s less hard-working than me.be similar to与……相像的/类似的，相当于be like。
7. serious adj.严肃的；稳重的serious用作形容词，用来指人的表情严肃或事情严重，常用短语：be serious about＂对……认真＂。
