四、重难点突破
help sb. (do) sth. 帮助某人做某事
help后面接某人,再接动词原形(do),表示「帮助某人做某事」。注意动词用原形,不需要加to,也不需要加-ing。这是英语中一个常见的句型结构。教材Find the rule板块中的例句都体现了这一结构:helps teachers clean、helps other students learn、helps his little brother clean。
Xiaopu always helps teachers clean the blackboard.(Xiaopu总是帮老师擦黑板。)
James often helps other students learn English.(James经常帮助其他同学学英语。)
Wenwen always helps his little brother clean the room.(Wenwen总是帮他弟弟打扫房间。)
【进阶训练】选择正确的选项:Yaoyao often helps me _____ my homework.
A. do B. does C. doing D. to doing
答案:A help sb. (do) sth. 中动词用原形,所以选 A. do。
often 与 always 频度副词的区别
often 意为「时常;经常」,表示动作发生的频率较高,但不是每次都发生;always 意为「总是」,表示动作每次都发生,频率比 often 更高。频度副词放在 be 动词之后,实义动词之前。这两个词在教材Chant time板块中分别出现了:They often share work... 和 We always cheer their goals.
They often share work with each other.(他们经常互相分享工作。)
We always cheer their goals.(我们总是为他们的进球欢呼。)
She always says "please".(她总是说“请”。)
【进阶训练】选择正确的选项:He _____ gets up at 6:00. He never gets up late.
A. often B. always C. sometimes D. never
答案:B never gets up late 说明他从不迟到,表示频率最高,用 always,所以选 B。
be good at 擅长
be good at 意为「擅长……」,后接名词或动词-ing形式。be动词根据主语变化:I am / You are / He is / She is / We are / They are good at...。教材Chant time板块中出现了:Minmin is good at football. Xiaopu is good at basketball.
Minmin is good at football.(Minmin擅长踢足球。)
Xiaopu is good at basketball.(Xiaopu擅长打篮球。)
She is good at painting pictures.(她擅长画画。)
【进阶训练】选择正确的选项:Shenshen _____ good at telling stories.
A. am B. is C. are D. be
答案:B Shenshen 是第三人称单数,be 动词用 is,所以选 B。
