1.Can people prevent certain accidents?
prevent为及物动词,意为“阻止,预防”,常用结构prevent sb. from doing sth.意为“阻止某人做某事”,与stop sb. from doing sth.用法相同。
2.So be careful!
careful为形容词,意为“小心的,仔细的”,其副词形式为carefully,意为“小心地,仔细地”;名词形式为carefulness,意为“小心,仔细,认真”。3.Many people hurt themselves by falling off chairs.
◆hurt oneself意为“伤着自己”。hurt themselves表示“伤到他们自己”,其中themselves是反身代词。
◆fall off意为“掉下来”,强调“从什么地方掉下来”,相当于drop/fall down from,后面接名词作宾语。
4.Don’t use water to put out kitchen fires.
◆这是一个否定形式的祈使句。以动词原形开头的祈使句变为否定形式时,多在动词原形前加don’t。
◆use sth. to do sth.意为“用某物做……”,to do不定式表目的。
◆put out意为“扑灭,熄灭”,是由“动词+副词”构成的动词短语,后接代词作宾语时,代词要放在put与out中间。
◆和fire相关的短语:catch fire(着火),make a fire(生火),discover a fire(发现火情),light/start a fire(点火),put out the fire(灭火),set fire to sth.=set sth. on fire(放火烧……),be on fire(失火,在着火)。5.Use baking soda or salt instead.
instead为副词,意为“代替,反而,却”,instead of也表示“代替”。
【辨析】 instead,instead of
instead常位于句末,译作“而是”,instead of常位于句中,译作“而不是”。
6.Be careful with scissors and knives!
be careful with意为“小心,谨慎……”。7.You don’t want to burn yourself.
burn在本句中为动词,意为“燃烧,烧毁,烧坏,烧伤”,其过去式、过去分词有两种形式,即burnt,burnt或burned,burned。
8.It’s easy to slip and fall on a wet floor.
不定式作主语时,往往用it作形式主语,而将不定式放在后面。这句话中的主语是to slip and fall on a wet floor,It是形式主语,is是系动词,easy是表语。9.Be sure to keep the bathroom floor dry after you have a shower or bath.
◆be sure to do sth.意为“务必/切记去做某事”,常用于祈使句中,表示说话人向对方提出要求。
【拓展】 be sure about/of意为“对……有把握,一定会”。
◆“keep+sth./sb.+形容词”意为“使……处于某种状态”,形容词作宾语补足语。
【拓展】 keep doing sth.一直做某事;keep sb. doing sth.让某人一直做某事。10.Never leave small children alone in a bathtub.
leave sb./sth. alone.意为“让某人/某物独自留下”。
【辨析】 alone,lonely
(1)alone作副词,用于陈述客观事实,强调独自一人,没有别的同伴;作形容词,在句中作表语或后置定语,强调别无其他,处境安全孤立。
(2)lonely作形容词,意为“孤独的,寂寞的”,具有感彩,在句中作表语或前置定语,修饰某地时,意为“荒凉的,偏僻的”。Make posters Today we talked a lot about how to keep safe at home.

the words in the box.☆教材解读☆
1.So do knives and scissors.
“so+助动词/情态动词/be动词+主语”是由so引导的倒装句,表示“一种情况也适应于另一人/物”。其中助动词、情态动词、be动词要与上句的助动词、情态动词或be动词和本句的主语一致,表示“某人/物也是”。
【拓展】 “so+主语+助动词/情态动词/be动词”表示对上句所描述的情况作进一步的肯定,表示“某人的确是”。上、下两句的主语为同一人。
2.These things should be kept away from children.
