Science Affects UsPPT，第三部分內(nèi)容：教材解讀
1.What would life be like without computers or mobile phones?
be like意為“像”,多指品質(zhì)、性格等內(nèi)在方面的相似。
【拓展】(1)look like偏于外貌上的形似。
(2)take after意為“(外貌或行為)像(父母)”。
2.Everyone here is fine.
everyone為不定代詞,意為“每個人,人人”。不定代詞作主語時,謂語動詞應(yīng)用單數(shù)形式;不定代詞被形容詞修飾時,形容詞應(yīng)后置;含有不定代詞的句子在進(jìn)行肯定和否定轉(zhuǎn)化時,可將不定代詞進(jìn)行變化;“不定代詞+else”意為“別的……”;不定代詞的所有格直接在詞尾加“’s”,“不定代詞+else”的所有格需在else后加“’s”。
3.I suggest you try it,too!
suggest為動詞,意為“提議,提出”,后可接名詞/v.-ing,或接that引導(dǎo)的賓語從句,that從句用“should+動詞原形”,should可以省略。
【拓展】suggestion作可數(shù)名詞,意為“建議,意見”。
4.First,get a jar full of water and a piece of cardboard.
本句中的短語full of water用在名詞jar之后作定語,不定式、介詞短語和定語從句等都可用在名詞后作定語。
5.Cover the jar with the cardboard and turn the jar over.
turn…over意為“將……翻過來。”
【拓展】 turn over還意為“移交,仔細(xì)考慮”。
6.The air pressure pushing up on the cardboard is higher than that of the water pushing down from inside the jar.
◆push up意為“向上推,提高”。
◆push down意為“向下按,推倒,壓倒”。
◆that用來替代“the+前述名詞”,以避免重復(fù)。
