☆教材解读☆
1.Whatwouldlifebelikewithoutcomputersormobilephones?
belike意为“像”,多指品质、性格等内在方面的相似。
【拓展】
(1)looklike偏于外貌上的形似。
(2)takeafter意为“(外貌或行为)像(父母)”。
2.Everyonehereisfine.
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.Isuggestyoutryit,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,getajarfullofwaterandapieceofcardboard.
本句中的短语fullofwater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.Coverthejarwiththecardboardandturnthejarover.
turn…over意为“将……翻过来。
”
【拓展】turnover还意为“移交,仔细考虑”。
6.Theairpressurepushinguponthecardboardishigherthanthatofthewaterpushingdownfrominsidethejar.
◆pushup意为“向上推,提高”。
◆pushdown意为“向下按,推倒,压倒”。
◆that用来替代“the+前述名词”,以避免重复。
7.Thehigherairpressureoutsidethejarholdsthecardboardinplace.
inplace意为“原位,在恰当的位置”。
【拓展】
(1)inplaceofsb./sth.=insb.’s/sth’splace代替/顶替某人/物
(2)takeplace发生
(3)takesb.’s/sth.’splace=taketheplaceofsb./sth.代替/替换某人/物
8.Yes,scienceisinteresting,anditaffectsoureverydaylives.
affect为及物动词,意为“影响”,相当于influence,常构成短语:
beaffectedby被……影响。
【拓展】effect为名词,意为“结果,影响”。
haveaneffecton意为“对……有影响”。
9.Ourliveswouldsurelybeverydifferentwithoutscientificdevelopments.
development为名词,意为“发展,成长”,thedevelopmentof意为“……的发展”。
【拓展】develop为动词,意为“(使)成长,发展”,adevelopingcountry发展中国家,adevelopedcountry发达国家。
10.Ialwayswonderwhatlifewouldbelikewithoutcomputersormobilephones.
wonder为及物动词,意为“惊奇,想知道”,相当于wanttoknow,其后可接“疑问词+动词不定式”结构和宾语从句。
【拓展】
(1)wonder还可作不及物动词,意为“觉得奇怪,想知道”,可构成短语wonderabout/at。
(2)wonder还可作可数名词,意为“奇迹”。
(3)wonderful为形容词,意为“美妙的”。
11.Scientificdiscoveriesaremakingourlivesbetterandbetter.
betterandbetter意为“越来越好”。
形容词或副词的比较级重复使用,并用and连接,表示程度的增加,意为“越来越……”,这一结构是“比较级+and+比较级”。
如果是多音节的形容词或副词表达这一含义时应用“moreandmore+形容词或副词的原级”表示。
【拓展】“the+比较级,the+比较级”意为“越……越……”。
