She brught the rses in,and then just lked at them in shck.她将玫瑰拿进屋,吃惊地看着它们。The failure was a great shck t me.那次失败给我很大的打击。There was smething wrng with the switch and I gt a shck.开关有问题,电了我一下。The patient was taken t hspital suffering frm shck.病人因休克被送往医院。
shck表示“吃惊;震惊;令人震惊的事情”时是可数名词,表示“(身心受到的)打击;震惊”和“休克”时是不可数名词。
3.breathe vi.& vt.呼吸【课文原句】Slwly,the city began t breathe again.慢慢地,这座城市又恢复了生机。【词汇精讲】句中的breathe意为“呼吸”,是不及物动词。breathe也可做及物动词。The air is s dirty that it is difficult t breathe.空气太脏了,呼吸很困难。Peple are cncerned abut the quality f the air they breathe.人们关心他们呼吸的空气的质量。

【词汇精讲】effrt表示一般性的努力(即表泛指意义),通常是不可数名词。若强调一次一次具体的努力,通常是可数名词,尤其与all,these等修饰语连用时。The film industry shuld make greater effrts t attract mre viewers.电影业要尽更大的努力吸引更多的观众。Parents arrange everything fr their children and spare n effrt t pave the way fr their success.父母为孩子安排好一切,不遗余力地为他们的成功铺路。

1.Chickens and even pigs were t nervus t eat,and dgs refused t g inside buildings.鸡,甚至猪都紧张得不吃东西,狗也不肯进入大楼里面去。【句式剖析】本句是一个并列句。在第一个分句中,句子的主语是Chickens and even pigs,动词不定式短语t eat做结果状语。 d sth意为“太……以致不……”,t后接形容词或副词,t是动词不定式符号,后接动词原形,动词不定式表示否定意义。The rad was t narrw fr large trucks t get thrugh because f landslide.由于滑坡,路太窄了,大型卡车通不过。The man was t tired t g any farther.那个人太累了,走不动了。
【句式拓展】在以下几种情况中,结构可以表示肯定意义,而不是否定意义:(1)当不定式前有否定词修饰时。He is t flish t understand this.他太蠢,不会明白这一点。He is t clever nt t understand this.他太聪明,不会不明白这一点。(2)当副词t的前面有否定词修饰时。Never t ld t learn.活到老学到老。It’s never t late t stp smking.戒烟何时都不算晚。
(3)当副词t后面修饰的形容词是glad,ready,pleased等表示“积极”意义的词汇时。We are t ready t help yu.我们很乐意帮助你。I shall be nly t pleased t get hme.我要回到家里就非常高兴。
2.It seemed as if the wrld were cming t an end!仿佛世界末日即将来临!【句式剖析】本句是一个主从复合句,主句是It seemed,as if引导的是表语从句。It lks as if/thugh it is ging t rain.看起来要下雨了。Be quick!It lks as if/thugh the train is ging t mve.快点!看起来火车要开了。
【句式拓展】as if =as thugh既可以引导方式状语从句也可以引导表语从句。当说话者认为句子所述的是不真实的或极少有可能发生或存在的情况时,从句虚拟语气动词时态的形式如下:
The wman lves the children as if/thugh she were their mther.这位女士爱这些孩子,好像她就是他们的妈妈一样。The girl listened as if/thugh she had been turned int a stne.那女孩倾听着,像已经变成了石头似的。如果as if引导的从句中的主语和主句的主语相同,且含有be动词,可省略从句主语和be动词,这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。
