【解析】

试题分析:本文是一篇说明文。睡眠对我们的身体健康非常重要,不同的年龄段需要的睡眠时间不同,对成年人来说,8小时的睡眠时间是最适合的。很多因素影响我们的睡眠质量,清新的空气,睡前洗一个热水澡,保持合适的体温都有助于我们拥有良好的睡眠。

【1】depends考查动词。分析句子成分,The amount of sleep needed为句子主语,depend的形式应与其保持一致,为第三人称单数,故答案为depends。

【2which考查关系副词。分析句子可知in后面的成分是修饰condition的定语从句,用where或in which,题目前以给出了in,故答案为which。

【3】the考查定冠词。The +adj.指代一类人,如The young“年轻人”,与之相对应,the old“老年人”,故答案为the。

【4but考察关联词。分析句意:有些人不用睡这么长时间,但其他人可能需要更多的睡眠时间。故答案为but“但是”。

【5It考查代词。还原句子: to satisfy his need is then a matter of good judgment.故it代指不定式短语作真正主语,形式主语只能用it。

【6】strength考查名词。分析句子,his后跟名词,题目已给参考词汇strong,变为名词形式strength,且符合题意。

【7】in考查介词。前句提到新鲜空气对保持良好睡眠很重要。分析句意:所以很多人理所当然地认为在户外睡觉是可行的。In the open air“在户外”,故答案为in。

【8】neither考查固定搭配。Neither...nor,“既不是...又不是...”,分析句意“睡前洗个澡,水温不要太热或太冷,适合体温就好...”,故答案为neither。

【9helpful考查固定搭配。Be helpful to “对...是有帮助的”;根据情景可知睡前一个热水澡对睡眠有帮助的作用,用题目所给参考单词help的形容词形式 helpful。

【10suggested考查动词语态。由by可知用动词的被动语态,分析句意:在医生建议前,不要用催眠药。

【题目】A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in a garden or a plant pot and wait for it to flower.

A biodegradable(生物所能分解的)mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle.

Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and is able to change shape. Over time it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms fertilizers. These feed the seed and help the flower grow.

Engineers have designed a small transparent(透明的)window to hold the seed. They have made sure it only grows when the phone is thrown away. “We’ve only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time,” said one scientist.

As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists.

“The seed comes out and the flower grows in the pot so you don’t have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.

【1】What is the purpose of this passage?

A. To tell the popularity of biodegradable cell phones.

B. To persuade the reader to buy the biodegradable cell phone.

C. To discuss the development of phone technology.

D. To introduce an environmental-friendly cell phone to readers.

【2】People throw away their cell phones most probably because .

A. there is something wrong with them

B. no sunflowers can grow out of them

C. they are out of fashion

D. they are becoming cheaper and cheaper

【3】It could be learned from the passage that .

A. developing the new type of phone is mainly to protect the environment

B. phone-makers will benefit much more from the new type of phone

C. the new type of phone will certainly be popular with users all over the world

D. the phones that can be recycled are available only in Britain now

【4】What might be the most suitable title for this passage?

A. Sunflower and Phone. B. Plant Your Phone.

C. Protect Our Environment. D. No Worry about Phone.

【题目】The 6yearold kid watched in silence as the man behind the desk,the headmaster of the school,shook his head more than once to his mother.

Minutes later,mother and son walked slowly out of the school,her right hand holding his little hand,her left holding an umbrella to shield(遮挡) both of them from the sun.“Where are we going now,mother?”asked the kid,looking up at her.“To another school,”was her gentle reply.For some reason,the little kid had not been accepted by the school,and she was taking him to another,to try to get him registered.That was more than 50 years ago.That woman was my mother;that little kid was me.

Fifty years later,the day after my mother had slipped into a coma(昏迷) from a stroke,I sat next to her,holding her hand,stroking it,watching her body heaved up and down as she breathed heavily,as if she was struggling with something.Her eyes were closed,her mouth opened.I whispered softly to her,“Mum,it’s okay.You have given us everything.You can let go now.No need to struggle anymore,Mum.”

A few days later,Mum died.At her bedside,I spent some time just looking at my mother,soaking in the finality of her death.There she was,my mother,motionless and lifeless.I took hold of her still warm but lifeless hand,holding it for the last time,recalling every piece of the precious moment we spent together.

I finally let go of her hand—lifeless,yet having given so much life to so many of us,and placed it next to her body.I found myself saying silently to her the only words that came to my mind,“Goodbye Mum,thank you for everything.”

Thank you,Mother,fornot giving up,so that I could go to school.Thank you for coaching me,for reading to me,for ironing my school uniforms,for combing my hair,for tying my shoe laces,for making sure I had a little handkerchief inside my pocket...

Rest in peace,Mother,you are still very much alive in us.Happy Mother’s Day.
