Unit 2 How often do you exercise? Section B1.She says its good for my health.她说它(牛奶)对我的健康有好处。be good for意为“对有益”,反义词组:be bad for意为“对有害”。如:Eating vegetables is good for your health.吃蔬菜对你的健康有益。【辨析】be good for,be good at与be good with词组意义例句be good for对有益Drinking milk is good for our health.喝牛奶对我们的健康有好处。be good at善长于Mark is good at making friends with others,so hes good with everyone.马克擅长与人交友,所以他与所有人相处得不错。be good with与相处得不错health不可数名词,意为“健康”;其形容词形式为healthy,意为“健康的”。如:Fresh air and exercise are good for the health.新鲜空气和运动有益于健康。The old man is very healthy.那位老人非常健康。2.We found that only fifteen percent of our students exercise every day.我们发现仅有15%的学生每天锻炼。本句是“find+that从句”的用法。如:I found that the job was very interesting.我发现这份工作很有趣。【拓展】find作“发现;发觉”讲时,其后可接各种形式的复合结构:“find+宾语+名词”结构如:We have found him(to be) a good boy.我们发现他是一个好孩子。“find+宾语+形容词”结构如:He found the room dirty.他发现这个房间很脏。“find+宾语+现在分词”结构如:I found her standing at the door.我发现她正站在门口。百分数由percent表示,构成:基数词+percent。percent没有复数形式,作主语时,根据它所修饰的名词来判断谓语的单复数。如:Seventy percent of the boys like playing computer games.70%的男生喜欢玩电脑游戏。Thirty percent of time passes.30%的时间过去了。3.Although many students like to watch sports,game shows are the most popular.尽管很多学生喜欢看运动类节目,但游戏类节目是最受欢迎的。although连词意为“虽然;尽管”,用来引导让步状语从句。如:Although he is very rich,he is unhappy.尽管他非常富有,但他并不快乐。注意:although不能和连词but连用,但可以和副词yet或still连用。the most popular是popular的最高级形式,意为“最受欢迎的”。如:Who is the most popular TV star?谁是最受欢迎的电视明星?4.It is good to relax by using the Internet of watching game shows,but we think the best way to relax is through exercise.通过上网或看游戏类节目是很好的放松方式,但我们认为最好的放松方式是通过锻炼。本句使用固定句式It is/was+adj.+to do sth.,意为“(对某人来说)做某事是的”。it是形式主语,放在句首,动词不定式作真正的主语,放在句末。为了句子平衡,将真正主语放在后面。如:Its not good to complain too much.抱怨太多是不好的。through介词,意为“以;凭借;通过”。如:I got the news through my uncle.我通过叔叔得到了这个消息。【拓展】through作介词时,还可意为“从的一端到另一端(表示方向);经过”。如:The river flows through the city.这条河流经城市。5.And remember,“old habits die hard”.请记住:“积习难改”。die可作及物动词,也可作不及物动词,意为“死亡;消失”。如:He died three years ago.他3年前就死了。【拓展】dead形容词,意为“死的,死亡的”;death名词,意为“死亡”。6.However,she has some bad habits,too.然而她也有一些坏习惯。however在此为副词,意为“然而;无论如何;不过”,可以位于句首、句中和句末,位于句首时,要用逗号与句子其他部分隔开;位于句中时,其前后都要用逗号;位于句末时,其前用逗号分开。如:She was ill.However,she still went to work.她病了,然而她依然去上班。His brother,however,had other ideas.然而他的哥哥却有别的想法。【辨析】however与buthowever“然而;可是”,既可作副词,也可作连词不能直接连接两个分句,必须另起新句,用逗号隔开,表示的是一种补充关系but“可是”,一般作连词可连接前后两个分句,意义上表示的是一种转折关系It began to rain.However,we went out to look for the boy.天开始下雨了,不过我们还是出去寻找那个男孩了。It is a sunny morning,but very cold.这是一个晴朗的早晨,但是却很冷。7.She usually watches TV for more than two hours a day.她通常每天看两个多小时的电视more than相当于over,意为“超过;多于;不仅仅”。如:I lived in Chongqing for more than/over ten years.我在重庆住了10多年了。8.she never goes to the dentist for teeth cleaning.她从不为清洁牙齿去看牙医。go to the dentist意为“去看牙医”。如:How often do you go to the dentist?你多久去看一次牙医?9.Almost every day.几乎每天。almost副词,意为“几乎;差不多”。almost一般置于实义动词之前,连系动词、助词和情态动词之后;almost不能置于句末。如:I almost forget to write to him.我几乎忘记了给他写信。It was almost like a good dream.这几乎就像一场美梦。10.Less than six.不到6个小时。less than意为“不到;少于”;其反义词组为more than,意为“多于;超过”。如:We live here for less than two years.我们在这儿住了不到两年。We know each other for more than twenty years.我们互相认识了20多年了。例1(xx济南)Have you ever been to Disneyland?No,.I hope I can go there next year.A.always B.sometimes C.never D.often解析：考查副词。由句意“我希望我明年能去那。”可知“我”从未去过迪斯尼乐园。答案：C例2(xx重庆)Mr.Li asks the studentsin the river,because its too dangerous.A.swim B.to swim C.not to swim D.to not swim解析：考查固定用法及搭配。Ask sb. to do sth 意思为：让某人做某事。答案：B那些美丽的花儿The Nice FlowersAs the sun rose over the horizon, I went out to enjoy the beauty of the grassland scenery. On the way, I saw a pair of red flowers blooming. They had flat petals and were incredibly full of smiling beauty. Those independent flowers seemed very vibrant. Gazing at the flowers made me think of many things.当太阳升过地平线时，我走出屋外来欣赏草原的美景。在路上，我看见两朵红色的花在绽放。花瓣平展，花朵有着让人无法抵御的美丽。这些自由的花朵充满了活力。看见这些花儿让我想起许多事。Dew like pearls shone on the grass brightly. Rays of sun offered happiness. I stood and stared at the beautiful flowers for a long time, enjoying the bright, pleasant sunshine. Butterflies and little bees were flying about. Then some naughty children with sticks came. One child swung his stick when he saw the flowers. Many petals fell to the earth, and with them, my heart fell too.草上的露珠像晶莹剔透的珍珠在闪烁。阳光送来了幸福。我站在那儿，长久凝视着这些花儿，享受着明亮而又惬意的阳光。蝴蝶和蜜蜂在花丛中飞舞。这时，2个拿着棍子的淘气小男孩来到这里，有个男孩一看到这些花，马上就挥起了棍子。许多花瓣掉落到地上，我的心也随之跌入低谷。The next day, beside the road, the red flowers were brighter than the day before. The natural beauty made me gasp. It gave me an understanding of the energy of growing and youth and convinced me it couldnt be destroyed with a heartless stick. I wanted to be like the soul of a flower.第2天，路边的那2朵红花看起来比前一天更加娇艳。自然的美丽让我几乎窒息。它让我理解了成长和青春的力量，使我相信那是棍子所不能摧毁的，我也想拥有像花儿一样的灵魂。Then I saw an old woman and child coming along the road. When they reached the flowers the child quickly plucked one. I felt great horror and then heard the old woman say, What beautiful flowers.
