高频易错点01
Nikki: A typhoon is coming tomorrow!
Yafei: Don’t worry. Just close the windows to keep out the strong wind.
译文:尼基:明天台风就要来了! 亚菲:别担心。关上窗户挡住大风就好。(P39)
be coming 表将来
易错点提示
💡 1. be coming 表将来
come/go/leave/arrive 这类位置移动动词,用现在进行时(be+doing)表达即将发生的事,译为 “就要、将要”。主语是单数名词时 be 动词用 is。 易错:A typhoon are coming tomorrow!
💡 2. to do 不定式表目的
句中 to keep out the strong wind,动词不定式 to do 放在句子末尾,用来表示做动作的目的(关窗户,目的是挡住大风)。 易错:Just close the windows keep out the strong wind.
💡 3. keep out 短语
keep out 是固定短语,含义:把…… 阻挡在外、不让…… 进入。不要误写为 keep off(远离)。
💡 4. 祈使句
Don’t worry. 和 Just close the windows... 都是祈使句。肯定祈使句以动词原形开头;否定祈使句用 Don’t + 动词原形。 易错:Don’t worrying. / Just closes the windows.

点拨
一、单项选择
1.A
解析:主语 a typhoon 是单数名词,be 动词用 is,be coming 表即将到来。
2. B
解析:to do 不定式表目的,关门的目的是阻挡冷空气,用 to。
3. A
解析:否定祈使句结构:Don’t + 动词原形,所以用 worry。
4. A
解析:固定短语 keep out 把…… 挡在外面。keep off 含义是远离,不符合本句语境。
5. B
解析:Don’t 后面要接动词原形 worry。
二、判断正 (T) 误 (F)
1.F
解析:主语 a typhoon 是单数,be 动词要用 is,不能用 are。
2.T
解析:祈使句动词原形开头,to do 表目的,句子语法正确。
3. F
解析:Don’t 后面需要加动词原形,应该是 Don’t worry。
三、连词成句
Close the windows to keep out the strong wind.
解析:祈使句以动词 close 开头,to keep out... 作目的状语。
高频易错点02
Nikki: Okay. Anything else I should do?
Yafei: You’ll also need to turn off the lights. Oh! Don’t forget to bring everything inside.
尼基:好的。还有别的我需要做的事吗?
亚菲:你还需要关掉灯。哦!别忘了把所有东西都拿到屋里来。(P39)
need to do sth 需要做某事
易错点提示
💡 1. need to do sth 需要做某事
need 在这里是实义动词,后面要接 to + 动词原形,结构:need to do sth。 易错:You’ll also need turn off the lights. / You’ll also need turning off the lights.
💡 2. turn off 固定短语
turn off 意为 “关掉(电器、灯、水龙头等)”;反义词组 turn on 打开。不要误写 turn of。
💡 3. forget to do sth 忘记要去做某事
forget to do 表示忘记要做(事情还没做);forget doing 是忘记做过某事(事情做完了,但忘了)。本句提醒对方别忘了要拿东西,用 forget to do。 易错:Don’t forget bring everything inside.
💡 4. anything else 还有别的东西 / 事情
else 放在不定代词 anything, something, nothing 后面,表 “别的、其他的”,不能放在代词前面。 易错:Anything else → else anything
💡 5. You’ll = You will
will 是情态动词,后面必须接动词原形。You’ll need… = You will need…

高频易错点03
If you happen to be outside, get to a safe place quickly. Stay away from trees! Watch your step and don’t run. Wear a colourful raincoat so others can see you. Remember, a raincoat is better than an umbrella.
如果你恰巧在户外,迅速到安全的地方。远离树木!小心脚下,不要奔跑。穿上颜色鲜艳的雨衣,这样别人能看见你。记住,雨衣比雨伞更好。(P40)
if 引导条件状语从句
易错点提示1
💡1. if 引导条件状语从句
if 意为 “如果”,引导条件状语从句。遵循主将从现;本句主句为祈使句(动词原形开头表劝告),从句用一般现在时。 易错:If you will happen to be outside…
💡2. happen to do sth 碰巧做某事
固定搭配 happen to + 动词原形,表示 “碰巧、恰巧发生”。 易错:happen to doing /happen do
💡3. stay away from 远离……
固定短语 stay away from,后接名词,意思是远离,不要写成 stay away for。
💡4. 祈使句(肯定 & 否定)
肯定祈使句:动词原形开头(Get to… / Stay away… / Watch… / Wear…) 否定祈使句:Don’t + 动词原形(don’t run) 易错:Don’t to run. / Not run.
💡5. better than 形容词比较级
better 是 good 的比较级,than 用于两者比较,表示 “比…… 更”;than 后面接对比对象。 易错:good than /better then
💡6. a /an 冠词辨析
an 用于元音音素开头单词前:an umbrella;a 用于辅音音素开头单词前:a raincoat。 易错:a umbrella /an raincoat
