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】試題分析:本文主要講述近些年來科學家們通過研究發(fā)現(xiàn):雖然大腦思維能力和速度會隨著年齡的增長而降低,但是通過鍛煉,還是可以保持甚至提高的。

1考查代詞。句意:人們過去認為這是不能避免的,然而最新研究表明,任何年齡的人都可通過一些訓練來使頭腦更靈活。it作形式主語,真正的主語是從句“that this couldn’t be helped”,置句首單詞首字母大寫。故填It。

2考查非謂語動詞。句意:給予一些適當?shù)墓ぞ,我們可以訓練我們的大腦,使其能像過去我們年輕時一樣工作。___2___ (give) the right tools”作狀語,與主語we是被動關系,用過去分詞作狀語表示被動關系,置句首單詞首字母大寫。故填Given。

3考查動詞。句意:我們所需要的只是為使大腦達到特定目標而設計的一些訓練。“that ___3___(require)”是定語從句修飾all,引導詞that在從句中作主語,故require與先行詞all保持人稱和數(shù)的一致,根據(jù)語境,all看作整體,視為單數(shù),句子用一般現(xiàn)在時,故require用第三人稱單數(shù),require與主語all既可以看作主動關系也可以看作被動關系。故填is required/requires。

4考查冠詞。句意:我們所需要的只是為使大腦達到特定目標而設計的一些訓練。the mind此處指“大腦”。故填the。

5考查定語從句。句意:Merzenich博士開發(fā)了一種基于計算機的訓練方式來提高大腦在處理信息過程的速度。___5___ the brain deals with information”是定語從句,修飾the process,從句中作介詞賓語,指物,用關系代詞which。故填which。

6考查介詞。句意:在訓練過程當中,程序會讓你辨別聲音,比如,dogbog這兩個單詞的辨別,而且以一種慢慢加快的速度。at an…speed“以一種……速度”是常用搭配。故填at。

7考查形容詞比較級。句意: Merzenich博士說,這有點像網(wǎng)球教練,以越來越快的速度把球擊向你,不斷給你挑戰(zhàn)。“比較級+and+比較級”表示“越來越……”是固定用法。故填faster。

8考查狀語從句。句意:如果你讓大腦不斷學習,他就能不停汲取知識。根據(jù)語境,前一分句可以是后一分句的條件也可以用作時間狀語從句,置句首單詞首字母大寫。故填If/When/Once。

9考查名詞。句意:為了你的大腦保持年輕和可塑性,方法有上百萬種,你只要從這些能給你挑戰(zhàn)和刺激的方式中選取一個即可,比如:打乒乓,打橋牌,做填字游戲,學習一種新語言等。activity“活動”是可數(shù)名詞,由a million修飾用復數(shù)。故填activities。

10考查非謂語動詞。句意:當涉及到避免衰老的時候,要么好好利用,要么就會逝去而無法挽回了。when it comes to…“當涉及到……的時候”是固定短語,to是介詞,后接動名詞作賓語。故填preventing。

【題目】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.

【題目】任務型閱讀
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 (誘餌).” 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.
B. It provides me my best time to think.
C. So is listening to some soft classical music.
D. In all, Edison has thousands of inventions.
E. He was asked the reason behind him being a fisherman.
F. To make your brain work better, you need to take a rest.
G. Set aside 15-20 minutes per day so that you can do nothing.

【題目】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 (格拉諾拉燕麥棒)are healthy.Interesting,less than 30 percent of nutritionists(營養(yǎng)學家)agree.

Nearly 80 percent of teenagers say they don’t like to eat cereal porridge(燕麥粥)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.
