五、补充易错点说明
1.过去式变形:本单元短语多为过去时语境,重点标注了不规则动词过去式,如:
sweep→swept;blow→blew;beat→beat;hide→hid;bring→brought;run→ran;wake→woke
2.介词搭配:
· warn sb. of/about sth.(√);warn sb. of doing sth.(×,应为 warn sb. about doing sth.)
· pay attention to(√,to 为介词,后接动名词)
· safeguard…from…(√,表 “保护免受伤害”)
3.易混短语辨析:
go out vs. put out(核心区别:动作对象+含义侧重,结合单元灾害场景详解)
1. go out:不及物动词短语,无被动语态,侧重“自然熄灭、停止运行”,无需人为干预,单元中主要用于“停电、闹钟停响、火焰自然熄灭”。
-单元语境例句:
The power went out suddenly when the typhoon hit.(台风袭击时,突然停电了。)
My alarm clock went out last night, so I woke up late.(我的闹钟昨晚没响,所以我醒晚了。)
The small fire went out by itself after the rain.(雨后,小火苗自己熄灭了。)
2. put out:及物动词短语,可用于被动语态,侧重“人为主动熄灭、扑灭”,动作发出者是人(如消防员、普通人),单元中主要用于“灭火”。
单元语境例句:
The firefighters worked hard to put out the wildfire.(消防员奋力扑灭了野火。)
We used water to put out the small fire in the kitchen.(我们用水扑灭了厨房里的小火。)
易错提醒:不可说“The fire was gone out.”(错误,go out无被动),正确表达:The fire went out. 或 The fire was put out.
slow down vs. calm down(核心区别:修饰对象+含义侧重,结合单元场景区分)
1. slow down:侧重“速度、节奏减缓”,修饰的对象是“可移动、可变化的事物”(如风、雨、车辆、动作等),单元中主要用于“风力、雨势减弱”。
单元语境例句:
The wind slowed down after midnight, so we felt a little safer.(午夜后风变小了,我们感觉安全了一些。)
The rain slowed down gradually, and the sun came out.(雨渐渐小了,太阳出来了。)
The car slowed down when it passed the flooded road.(汽车经过被淹的道路时放慢了速度。)
2. calm down:侧重“情绪、气氛平静下来”,修饰的对象是“人、情绪、场面”,单元中可用于描述灾害中人们的情绪变化。
单元语境例句:Please calm down. The typhoon will pass soon.(请冷静下来,台风很快就会过去。)
After the storm, people gradually calmed down and started to clean up the neighbourhood.(暴风雨过后,人们逐渐平静下来,开始清理街区。)
易错提醒:描述“风变小”不可用calm down,描述“情绪平复”不可用slow down,避免搭配混淆。
happen vs. take place(核心区别:发生的“偶然性/计划性”,结合单元灾害场景详解)
1. happen:不及物动词,侧重“偶然、意外发生”,无计划、无预兆,单元中所有自然灾害(地震、台风、海啸等)均属于“偶然发生”,常用此词。
单元语境例句:An earthquake happened in Indonesia before the tsunami.(海啸发生前,印度尼西亚发生了一场地震。)
A terrible wildfire happened in Chongqing in 2022.(2022年重庆发生了一场严重的野火。)
补充搭配:happen to do sth.(偶然做某事),如:I happened to see the lightning when I went out.(我出去的时候,碰巧看到了闪电。)
2. take place:不及物动词短语,侧重“有计划、有预兆地发生”,多用来描述“活动、事件、仪式”等,单元中几乎不用于描述自然灾害(除非指灾害“有预兆地发生”,但极少用)。
语境例句:The school meeting will take place tomorrow morning.(学校会议将于明天上午举行。)
The concert took place as planned despite the bad weather.(尽管天气不好,音乐会还是按计划举行了。)
易错提醒:自然灾害(地震、台风等)优先用happen,不用take place;take place无被动语态,不可说“Something was taken place.”,正确表达:Something took place.
