Science Affects UsPPT，第三部分内容：教材解读

1.What would life be like without computers or mobile phones? 

be like意为“像”,多指品质、性格等内在方面的相似。

【拓展】(1)look like偏于外貌上的形似。

(2)take after意为“(外貌或行为)像(父母)”。

2.Everyone here is fine. 

everyone为不定代词,意为“每个人,人人”。不定代词作主语时,谓语动词应用单数形式;不定代词被形容词修饰时,形容词应后置;含有不定代词的句子在进行肯定和否定转化时,可将不定代词进行变化;“不定代词+else”意为“别的……”;不定代词的所有格直接在词尾加“’s”,“不定代词+else”的所有格需在else后加“’s”。

3.I suggest you try it,too! 

suggest为动词,意为“提议,提出”,后可接名词/v.-ing,或接that引导的宾语从句,that从句用“should+动词原形”,should可以省略。

【拓展】suggestion作可数名词,意为“建议,意见”。

4.First,get a jar full of water and a piece of cardboard. 

本句中的短语full of water用在名词jar之后作定语,不定式、介词短语和定语从句等都可用在名词后作定语。

5.Cover the jar with the cardboard and turn the jar over. 

turn…over意为“将……翻过来。”

【拓展】　turn over还意为“移交,仔细考虑”。

6.The air pressure pushing up on the cardboard is higher than that of the water pushing down from inside the jar. 

◆push up意为“向上推,提高”。

◆push down意为“向下按,推倒,压倒”。

◆that用来替代“the+前述名词”,以避免重复。
