Can Training Your Working Memory Make You Smarter？ We would all like to increase our cognitive （認(rèn)知的） ability beyond the limits set by Mother Nature.So it's no wonder that brain-training programs — which focus on training our working memory — are a multibillion-dollar industry.But can this kind of training really make us smarter？
Cognitive training sees the brain as a kind of muscle （肌肉） that can be made stronger with the right kind of practice.Although people did much research，there has been no agreement about its effectiveness.Some think that cognitive training increases some cognitive abilities，while others less hopeful.
Yet we do know that some cognitive skills probably go together and are predictors of real-life skills such as work performance.Thus，training one cognitive skill might lead to an improvement in many other cognitive and non-cognitive skills.That is the key hypothesis （假設(shè)） on which working-memory training is based.
To test this hypothesis，we examined all the studies about working-memory training.The results were very clear.Working-memory training did not show any effect on children's fluid intelligence （流體智力），a person's ability to solve new problems and get used to new sjye.aiuations.It didn't influence their educational achievement or other cognitive abilities，eijye.air.The only dependable effect was that children got better at what they were trained to do.So performing working memory tasks does seem to make you better at doing them.However，the fact that participants （參與者） got better at such tasks does not necessarily mean that their working memory ability increased.They may just have learnt how to perform that type of task.
The results do show that the use of working-memory training programs as an educational tool is useless.Beyond working-memory training，other recent studies have shown the limitations of different types of cognitive training.
However，these negative （負(fù)面的） results must not discourage us from training our cognitive and non-cognitive skills.We just have to realize the actual limitations of such practice in areas outside what we are actually training.But that doesn't mean we shouldn't do it — the most efficient way to develop a skill is，after all，to train that skill.

1．Whales are the largest living organisms （生物）living on the surface of the earth.An adult blue whale weighs up to 173 tonnes with 30 meters in length.When a whale dies in the ocean，its body usually falls to the sea floor and a special deep-sea ecosystem will be formed in a long time.Scientists give a name to this：the whale fall.
Recently，some scientists on a Chinese research ship called Tansuo-1 found a whale fall at the depth of 1，600 meters in the South China Sea.Whale falls are seldom found by humans.This is the first time China has found this type of ecosystem.So far，less than 50 modern natural whale falls have been found by humans around the world.
The whale fall is really important to deep-sea animals，as it provides food for them.Usually，the whale fall goes through three stages.The first stage comes just after the whale dies.The body attracts lots of big sea animals such as shark and they come to eat the body.This stage lasts from months to years.At the second stage，smaller animals come for the whale's bones and leftovers.This stage can last one or two years.Bacteria （細菌）play a role at the third stage.They break down what has been left.This stage can last as long as 100 years.
The whale fall found in the South China Sea is 3 meters long.It is still at the first stage.The scientists said it would take them a long time to study the whale fall because they knew it would help them understand the deep-sea ecosystem better.
（1）When whales die in the ocean，most of their bodies usually.
A．a(chǎn)re saved by scientists
B．a(chǎn)re found on the beach
C．float on the ocean surface
D．sink to the bottom of the ocean
（2）The Chinese meaning of the underlined word "ecosystem" is.
A．經(jīng)濟學(xué)
B．生態(tài)系統(tǒng)
C．電子信息
D．環(huán)保體系
（3）The whale fall goes through the following stages，and the correct order is.
①Bacteria break down the rest of the whale.②Smaller animals eat the whale's bones.
③The whale dies in the ocean.④Big sea animals eat the whale's body.
A． ③④①②
B． ④③①②
C． ③④②①
D． ④③②①
（4）According to the passage，we know that.
A．a(chǎn)n adult blue whale weighs up to 173 tons
B．some scientists found a whale fall in the South China Sea
C．a(chǎn)t the first stage，smaller animals come for the whale's bones
D．the whale fall found in the South China Sea is in the third stage
（5）The best title for this passage maybe "".
A．The Whale Fall
B．A Chinese Research
C．Whales in the Ocean
D．The Deep-sea Ecosystem發(fā)布：2024/12/27 17:30:2組卷：13引用：3難度：0.5 -
2．When John was growing up，other kids felt sorry for him．His parents always had him working in the garden，carrying out the garbage and delivering newspapers．But when John reached adulthood，he was better off than his childhood playmates．He had more job satisfaction，a better marriage and was healthier．Most of all，he was happier．Far happier．
These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston．The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not．"Boys who worked in the home or community were better at dealing with problems and felt more confident．They believed they could achieve very much．" said George Vaillant ，the psychologist（心理學(xué)家）who made the discovery．"And because they felt good about themselves，others felt good about them．"
In the study，Vaillant's team compared these men's achievements with their boyhood working experiences．They paid attention to lots of details．They found out the success as adults had a lot to do with the boyhood activities．Those who did the most boyhood activities were twice as likely （可能的）to have warm relations with a wide variety of people，five times as likely to be well paid and 16 times less likely to lose their jobs．The study also suggested that IQ and family background made no real difference in how the boys turned out．Working-at any age-is important．Childhood activities ，such as part-time jobs，housework，effort in school and the ability to solve the problems help a child develop his abilities，which are keys to a happy world．They also help him understand that people must cooperate and work toward common goals．The most competent adults are those who know how to do this．Yet work isn't everything．As Tolstoy once said，"One can live magnificently in this world if one knows how to work and how to love，to work for the person one loves and to love one's work．"
（1）The passage mainly tells us．
A．John did a lot of housework when he was young

A．childhood activities help people get on well with others
B．those who had worked as boys could find a job easily
C．hard-working boys got paid more when they grew up
D．those who had kinds of childhood activities are less likely to lose jobs．

C．work together
D．care for
（5）The best title for passage is ""．
A．Learn to work from a young age

3．①Recently，I have finished four space tasks.I stayed in space for more than 43 days，and complete six spacewalks for 43 hours and 13 minutes，so I have a lot of experience there.Today，I want to share some information unusual：what it's like to eat in space.
②People often ask me if Tang- -a kind of orange drink mix--is still taken in space.Don't laugh，but we still drink it.Today's space foods look like foods we're used to eating every day.Foods，like nuts （堅果） or brownies （布朗尼蛋糕），can be taken on board as much as possible.But things like macaroni （通心面） or noodles would be specially prepared，then kept and packaged （打包） to stop them going everywhere .It's a difficult but necessary process.However，food on a space task can be quite rich and various，can't it？
③The microgravity （微重力） on the space station changes things in some ways.For one thing，there is no"up" or "down" in space.It also changes how things taste.On Earth，most of your blood is usually below your heart.In space，you're weightless，so the sharing of blood in your body changes.One result is lowering your sense of taste，at least at first.This happened to me on one task.When I took sugar candy，I wasn't able to taste it until the ninth day.
④Food can be a real happiness in space.For us，eating is more than just getting power and energy.Familiar foods and tastes can remind us of home and keep us feeling that we still keep in touch with Earth.
（1）What is the passage about？
A．Life in space.
B．Eating in space.
C．Exercise in space.
D．Sleeping in space.
（2）Who might the writer be？
