Ⅰ.阅读理解

A

Welcome to your future life!

You get up in the morning and look into the mirror.Your face is young-looking.In 2035，medical technology is better than ever.Many people could live to be 150，so at 40，you're not old at all.And your parents could have an anti-aging treatment.Now，all three of you look the same age!

You say to your shirt，“Turn red.”It changes from blue to red.In 2035，“smart clothes”contain

particles(粒子)much smaller than the cells in your body.The particles can be programmed to change your clothes' color or pattern.

You walk into the kitchen.You pick up the milk，but a voice says，“You shouldn't drink that！”Your fridge has read the chip(芯片)that contains information about the milk and it knows the milk is bad.In 2035，every kind of food in the grocery store has such a chip.

It's time to go to work.In 2035，cars drive themselves.Just tell your “smart car” where to go.On the way，you can call a friend using your jacket sleeve.Such “smart technology” is all around you.

So will all these things come true？“For new technology to succeed，”says a scientist called Andrew Zolli，“it has to be so much better that it replaces what we already have.”The Internet is one example—what will be the next?

【语篇解读】 本文主要对未来技术在我们的日常生活中的运用进行了展望。描绘了几种未来技术将如何影响我们的日常生活的画面。

2．What can be inferred from Paragraph 3? A．Milk will be harmful to health. B．More drinks will be available for sale.

C．Milk in the grocery store will stay fresh much longer. D．Food in the grocery store will carry electronic information.

D [推理判断题。根据第三段中的“In 2035，every kind of food in the grocery store has such a chip.”可知，未来的食品杂货店内的每一种食物都含有一个芯片，这种芯片含有关于这种食物的信息。]

3．Which of the following is mentioned in the text? A．Nothing can replace the Internet. B．Fridges will know what people need. C．Jacket sleeves can be used as a guide. D．Cars will be able to drive automatically.

A [主旨大意题。本文通过介绍未来的一些智能技术，例如智能服装、冰箱和汽车等，反映了未来技术在我们日常生活中的应用。]

B

What will people die of 100 years from now？If you think that is a simple question，you have not been paying attention to the revolution that is taking place in biotechnology (生物科技)．With the help of new medicine，the human body will last a very long time．Death will come mainly from accidents，murder and war.Today's leading killers，such as heart disease，cancer，and aging itself，will become distant memories.

In discussion of technological changes，the Internet gets most of attention these days.But the change in medicine can be the real technological event of our times.How long can humans live？Human brains were known to decide the final death.Cells are the basic units of all living things，and until recently，scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells，such as those of brain cells，would not last forever.But the upper limits will be broken by new medicine.Sometime between 2050 and 2100，medicine will have advanced to the point at which every 10 years or so，people will be able to take medicine to repair their organs.The medicine，made up of the basic building materials of life，will build new brain cells，heart cells and so on，in much the same way our bodies make new skin cells to take the place of old ones.

It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence，but many technical problems still must be cleared up on the way to this wonderful future.

【语篇解读】 在未来的100年，人类的生命由于生物科技的发展可以无限期延长的愿望有可能成为现实。

A [细节理解题。第二段前两句的意思是“在讨论技术变化时，人们往往注意到的是网络。然而药学方面的变化可能是当今技术方面的真正大事件”，故选A。]

7．Humans may live longer in the future because ． A．heart disease will be far away from us B．human brains can decide the final death C．the basic materials of cells will last forever D．human organs can be repaired by new medicine

D [推理判断题。 由第二段的后半部分可知，在2050 and 2100年间，每隔10年左右，人们可以通过服药来修复生病或衰老的器官，这是未来生命延长的原因。]

We are currently living in a world 1. rapid advances in medicine and technology influence our lives on 2. regular basis.One technology，which in recent years 3. (develop)very quickly，is cloning.

Clones refer to animals or plants that are produced to be exact 4. (copy)of one another.Clones of different kinds are produced in various ways，and they have become 5. (value) in many medical applications and biological experiments.Most are produced in the laboratory，with some of them 6. (occur) in several species in a natural way. A report in 2018 had pictures of Macaque monkeys that had been cloned successfully.Since they are primates(灵长目动物) like us，it gets us to come even 7. (close) to find the right procedures of the cloning of humans.

This comes to the question why we would need or want to do this.Would it be 8. the best interest of humankind to develop this technology？Besides，the moral questions that will be raised 9. (be)unbelievable，and would it be an accomplishment that could benefit humankind enough 10. (balance)the ill effects that it might produce? 【语篇解读】 本文是一篇说明文，主要介绍飞速发展的医学和技术常常影响着我们的生活，其中一种技术就是克隆，本文介绍了克隆的概念、现状以及存在的一些问题。

1．where [考查定语从句。分析句子结构可以发现，空前是主句，空处引导定语从句，修饰先行词world，空处在从句中作地点状语，故用where]。

2．a [考查冠词。飞速发展的医学和技术常常影响我们的生活。on a regular basis“定期地，经常地”，故填不定冠词a。]

3．has developed/has been developing [考查动词时态。根据时间状语“in recent years”可知，develop的动作从过去开始持续到现在，并有可能持续下去，故应用现在完成时或现在完成进行时，故用has developed或has been developing。]

4．copies [考查名词复数。copy在此表示“复制品”，是可数名词。根据后面的one another“彼此，互相”可知，此处copy不止一个，故用copy的复数形式。]

5．valuable [考查形容词。克隆在很多医疗应用和生物实验中变得很重要。根据语境和系动词后跟形容词的用法可知，此处用value的形容词形式valuable“珍贵的，很重要的，有用的。”]

6．occurring [考查非谓语动词。大多数克隆是在实验室中进行的，还有一些在一些物种身上自然发生。逗号前是完整的一个句子，逗号后是“with＋宾语＋宾补”的复合结构，因为occur是不及物动词，且occur与其主语在逻辑上是主谓关系，故用现在分词作宾补。注意：occur的现在分词形式是先双写r再加-ing。]

7．closer [考查副词的比较级。根据句意和空前的even可知，空处应用副词的比较级closer。]

8．in [考查介词。in the best interest of...意思是“对……最有利”，是固定搭配。] 9．are [考查时态和主谓一致。此处描述客观事实，故用一般现在时；由句子主语moral questions为复数可知，谓语动词应用are。]

10．to balance [考查非谓语动词。它会是一个可以让人类所获益处足以抵消它带来的负面影响的成就吗？enough to do sth.“足够做某事”。]
