（1）Can people prevent certain accidents？人们能阻止事故吗？

[来源学科网ZXXK]

T：Yes.Do you think your home is a safe place?

prevent动词，“防止；阻止”。常用句式：prevent sb. from doing sth.阻止某人做某事。[来源:Zxxk.Com][来源学&科&网Z&X&X&K]

（2）Many people hurt themselves by falling off chairs.很多人从椅子上掉下来而伤着自己。

themselves反身代词，“他们自己”，在句中作hurt的宾语。fall off...从……跌落。by＋doing sth.意为“通过……的方式”。

（3）Don’t use water to put out kitchen fires.不要用水去扑灭厨房的火。

本句为祈使句的否定形式。其构成为：Don’t＋动词原形。意为“不要……”。use sth. to do sth.用某物做某事。to do不定式表目的。put out熄灭。

（4）Use baking soda or salt instead.用小苏打或者盐代替。

本句为祈使句的肯定形式。其构成为：动词原形＋其他。salt名词，“盐”。其形容词为salty，“咸的”。

设计意图：培养学生综合阅读的能力，以及语言的实际运用能力。
