12、nstead是副词,在句中充当状语,常用于句首,起连接上下句的作用,通常是上句含有否定的意义,然后是用 instead引出下句,提出相反的情况,意为“反而” 。【例句】He didnt answer my question. Instead, he asked me another question. 他没有回答我的问题,反而问了我另一个问题。Tom doesnt study hard. Instead, he plays football all day. 汤姆学习不努力,反而整天踢足球。instead也可用在句末,意为“顶替、代替” 。【例句】Ann is tired. Let me do
13、 that instead.安累了,就让我来做那件事吧。Han Mei cant help us. Lets ask Lin Tao instead. 韩梅帮不了我们,咱们请林涛代替吧。【温馨提示】instead of和 instead在一定情况下可相互转换。6She went swimming tomorrow instead of playing basketball. =She didnt play basketball. She went to swimming instead. 她去游泳了,而没有打篮球。【课堂变式】Weve got no coffee. Lets have tea
14、_.A. either B. however C. yet D. instead【解析】either 意为“也(不) ”,通常用于否定句,位于句末;however“然而” ,通常位于句首或句中。yet“还,仍然,可是” ;instead 意为“代替,替代” ,只能位于句末,强调不做前面的事情,而做后面的事。根据句意为“我们没有咖啡了,喝茶吧”确定选 D。b. 句式包:1.Sixteen-year-olds should be allowed to get their ears pierced. 十六岁的青少年应该被允许扎耳洞。(1)should be allowed 是情态动词的被动结构,它是
15、由 “情态动词+be+及物动词的过去分词”构成。【备课例句】Many trees should be planted on the mountains. 应该在树上植许多树。Students should be allowed to go to school by bike.应该允许学生们骑自行车上学。把含情态动词的主动句变成被动句,即把“情态动词+动词原形”改为“情态动词+be+过去分词” ,此时,作主语的要用动词承受者。【备课例句】We should clean the classroom every day. The classroom should be cleaned every d
16、ay. 【横向辐射】该结构的句式转换1.否定句:在情态动词后加 not就行。【例句】These books cant be read for children. 这些书孩子们不能读。2.一般疑问句:直接将被动语态的陈述句的情态动词提到的句首。7【例句】Should Ann be allowed to wear her own clothes? 应该允许安选择自己的衣服吗?3.特殊疑问句:由疑问词加上含有情态动词的被动语态的一般疑问句构成。【例句】When must my homework be handed in? 我的作业必须何时交?4.对含有情态动词的被动语态的一般疑问句的回答, 一般应保

18、he instruction. A. should be carried B. must be put C. should be placed D. must be kept【解析】根据句意,主语 food是动作的承受者,用被动语态,而空格后的 cool是形容词,而“keep+某物+形容词”意为“使保持状态” ,故选 D。(2) “get+宾语+过去分词”结构意为“让被” ,其中过去分词和宾语之间这被动关系,该动作由他人(非主语本身)来完成,含有“被动意义且强调动作已经完成”的意思。get 可用 have替换。【备课例句】The driver got/had his car washed on
19、ce a week. 那位司机每周叫人洗一次车。Youd better get/have that bad tooth pulled out. 你最好把那颗坏牙拔掉。【课堂变式】get sb to do sthget sb to do sth 意为“让某人做某事” ,相当于 have sb do sth,前者不定式须带 to,后者不定式不带 to。不定式作宾语补足语,与宾语具有主动关系,表示宾语要做的事。8【例句】The soldiers got the boy to stand with his back to his father. (=The soldiers had the boy s
20、tand with his back to his father. 士兵让这男孩背对父亲站着。 【课堂变式】Did you have anyone _ the trees?Yes, I had the trees _.

21、示被动意义,正确答案为 D。2.He should stop wearing that silly earring.他应该不戴那个愚蠢的耳环。stop doing sth. 表示的是“停止做(正在做的)某事” ,这里的 doing sth.为动名词短语,所表示的行为发生在 stop 之前,作 stop 的宾语。【备课例句】She stopped crying and listened to the music. 她停止哭泣,听起音乐来。Class begins. Stop playing basketball, please. 开始上课了,请停止打篮球。【横向辐射】stop to do sth
22、 stop to do sth. 表示的是“停下来(原来做的事)去做(另外的)某事” ,这里的to do sth.是不定式短语,所表示的行为发生在 stop 之后,作 stop 的目的状语。【例句】They walked for a while and stopped to have a rest. 他们走了一会儿,便停下来休息一下。When she came in, we stopped to talk with her. 她进来时,我们停下来和她交谈。【课堂变式】Dad, why should I stop _ computer games?For your health, my boy, Im afraid you _. A. to play; must B. playing; have to C. to play; can D. playing; may 9【解析】句意为“爸爸,为什么我应该停止玩电脑游戏?” “为了你的健康,我的孩子,恐怕你必须这样做。 ”由 For your health可知是要停止玩游戏,这也是客观原因必须这样做,故选 B。
