【题目】阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

Our brains naturally start slowing down at the cruelly young age of 30.1 used to be thought that this couldn’t be helped,but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,”says Dr.Merzenich from University of California.2 (give) the right tools,we can train our acts as they did when we were young.All that 3(require) is the practice designed just for this purpose: a few exercises for 4mind.

Dr.Merzenich has developed a computer-based training method to speed up the process in5 the brain deals with information.Since much of the data we receive comes through speech,the Bain Fitness Program works with language and hearing to improve speed and accuracy.

Over the course of the training,the program starts asking you to distinguish sounds-between“dog” and “bog”,for example-6an increasingly faster speed.It’s a bit like a tennis instructor,says Dr.Merzenich,hitting balls at you faster and 7(fast) to keep you challenged.You may start out slow,but before long you’re pretty quick.

The biggest finding in brain research in the last decade is that the brain at any age is highly plastic.8 you ask your brain to learn,it will learn.And it may speed up in the process.

To keep your brain young and plastic,you can do one of a million new 9 (activity) that challenge and excite you: playing table tennis or bridge,doing crossword puzzles,learning a new language…“When it comes to10(prevent) aging,you really do‘use it or lose it’”,says Barbara Sahakian ,a professor at Cambridage University.

【解析】试题分析:本文主要讲述近些年来科学家们通过研究发现:虽然大脑思维能力和速度会随着年龄的增长而降低,但是通过锻炼,还是可以保持甚至提高的。

1考查代词。句意:人们过去认为这是不能避免的,然而最新研究表明,任何年龄的人都可通过一些训练来使头脑更灵活。it作形式主语,真正的主语是从句“that this couldn’t be helped”,置句首单词首字母大写。故填It。

2考查非谓语动词。句意:给予一些适当的工具,我们可以训练我们的大脑,使其能像过去我们年轻时一样工作。___2___ (give) the right tools”作状语,与主语we是被动关系,用过去分词作状语表示被动关系,置句首单词首字母大写。故填Given。

3考查动词。句意:我们所需要的只是为使大脑达到特定目标而设计的一些训练。“that ___3___(require)”是定语从句修饰all,引导词that在从句中作主语,故require与先行词all保持人称和数的一致,根据语境,all看作整体,视为单数,句子用一般现在时,故require用第三人称单数,require与主语all既可以看作主动关系也可以看作被动关系。故填is required/requires。

4考查冠词。句意:我们所需要的只是为使大脑达到特定目标而设计的一些训练。the mind此处指“大脑”。故填the。

5考查定语从句。句意:Merzenich博士开发了一种基于计算机的训练方式来提高大脑在处理信息过程的速度。___5___ the brain deals with information”是定语从句,修饰the process,从句中作介词宾语,指物,用关系代词which。故填which。

6考查介词。句意:在训练过程当中,程序会让你辨别声音比如,dogbog这两个单词的辨别而且以一种慢慢加快的速度。at an…speed“以一种……速度”是常用搭配。故填at。

7考查形容词比较级。句意: Merzenich博士说,这有点像网球教练,以越来越快的速度把球击向你,不断给你挑战。“比较级+and+比较级”表示“越来越……”是固定用法。故填faster。

8考查状语从句。句意:如果你让大脑不断学习,他就能不停汲取知识。根据语境,前一分句可以是后一分句的条件也可以用作时间状语从句,置句首单词首字母大写。故填If/When/Once。

9考查名词。句意:为了你的大脑保持年轻和可塑性方法有上百万种你只要从这些能给你挑战和刺激的方式中选取一个即可,比如:打乒乓,打桥牌,做填字游戏,学习一种新语言等。activity“活动”是可数名词,由a million修饰用复数。故填activities。

10考查非谓语动词。句意:当涉及到避免衰老的时候,要么好好利用,要么就会逝去而无法挽回了。when it comes to…“当涉及到……的时候”是固定短语,to是介词,后接动名词作宾语。故填preventing。

【题目】The Humane Society of Utah,a non-profit organization,is the largest shelter in the state because it takes every animal that can be lawfully accepted.The shelter employed photographer Guinevere Shuster,from New York,who came up with a creative way to find new homes for the dogs.She took lively photos for them.

【题目】任务型阅读
Thomas Edison was one of the most successful inventors the world has ever seen.
But people found that although Edison was good at inventing new things, he was a poor fisherman. He used to spend an hour almost every day sitting at the side of a river and fish. He always fished all alone by himself.
People asked Edison, “Why are you so crazy about fishing when you are so bad at it?” His answer was, “I really never caught ant fish because I have never used any bait (诱饵).” Another question followed, “Why would you fish without bait?” Edison answered, “Because when you fish without bait, people don't disturb you and neither do the fish
Sometimes the world's best inventor was the world's worst fisherman. In fact, because Edison was the world's worst fisherman, he could become the world's greatest inventor.
Are you setting aside some time for yourself to think? Here are some ideas for you:
Slowing down and taking long showers is a good idea.

Long walks are good too.
Afternoon naps have been proved to improve creativity.
A. But he never caught any fish.

C. So is listening to some soft classical music.
D. In all, Edison has thousands of inventions.

【题目】The Today I learned–The New York Times’ fun column always highlights some surprising and interesting facts. In that spirit,The New York Times lists some of the most eye-catching things out of the column and edits them into What I Learned This Year.Following are some facts out of What I Learned in 2016.

The world’s most-used natural resource (apart from water,listed at the second place and air,as the champion) is sand,which consists of extremely small pieces of stone-and it’s disappearing.

A team’s success (at work) is often driven by 3 factors (with the importance from high to low) —its culture,the interpersonal relationship and the IQ or talent of its individuals.

Giraffes have been keeping a secret from most of us for a long time: They’ really four different species,not one. The Greenland Shark lives at least 272 years and it could live as long as 512 years,which makes it the oldest living thing with a backbone(脊椎)on Earth.

More that 70 percent of Americans think Granola Bars (格拉诺拉燕麦棒)are healthy.Interesting,less than 30 percent of nutritionists(营养学家)agree.

Nearly 80 percent of teenagers say they don’t like to eat cereal porridge(燕麦粥)for breakfast,because they have to clean up the bowls after eating it.

It’s myth that closing unused apps on your smartphone will prolong battery life.And turning off Wi-Fi doesn’t help,either.

Annual percentage of highway death had been going down for the last four decades till it last year recorded the largest increase in 50 years.Blame Snapchat and other smarphone apps.

Death from gun-shooting is as enough as from car accidents in the United Stated and as scarce as from lightning strikes in Japan,which owns the reputation of one of the safest countries.

1According to the passage,the world’s most-used natural resource is______.

A. water B. air C. sand D. stone

2According to the passage,the most important factor of a team’s success is_____.

A. a team’s culture B. the interpersonal relationship C. individual IQ D. individual talent

3Which of the following descriptions is TRUE according to the passage?

A. Most people still don’t know that giraffes have four species.

B. The Greenland Shark is the oldest living life on Earth.

C. Cereal porridge is as unhealthy as Granola Bars for teenagers.

D. Closing unused apps on smart phones will prolong battery life.

4The underlined word “scarce” in the last paragraph is closest in meaning to ____.

A. enough B. safe C. familiar D. rare

During last summer holiday, I found part-time job, worked in a toothbrush factory at night. Not until I experienced it did I realized that it was no easy job. I went to work when my parents were going to bed. On the morning, when my parents were going to work, I came to home to sleep.
This backward schedule was very tough for me that I often felt tiring. But I am glad that I had this forgettable experience. Not only is it kind of fun to “rise and shine” along with the moon or stars, but also I learn to appreciate the hard work of those which are working while the rest of us are sleeping.
