Almost everyone wants to get smarter. We struggle to improve our   (1)  , intelligence and attention. We drink cup after cup of coffee to help us   (2)   the day.

  (3)  , a new study published in Current Directions in Psychological Science warns that there are   (4)   to how smart humans can get.

Each of our body parts develops in a certain way for a reason.   (5)  , we are not 3 meters tall   (6)  most people’s hearts are not strong enough to send   (7)  up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of   (8)  , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more   (9)  during childbirth.

The study of Jews, who have an average IQ much   (10)  than other Europeans, showed they were more   (11)  to develop diseases of the   (12)   system. This might be because of their increased brainpower.

If intelligence cannot be improved, can we at least get better at   (13)  ? Not really, say scientists. They studied   (14)   like caffeine (咖啡因) that improve attention. They found the drugs only helped people with serious   (15)  problems. For those who did not have trouble paying attention, the drugs could have the   (16)   effect. Scientists say that this suggests there is a(n)   (17)   limit to how much people can or should concentrate.

   Our memory is also a “double-edged sword”. People with extremely good memories could   (18)  having a difficult life because they cannot   (19)   bad things that happen to them.

Thomas Hills, one of the authors of the paper, said that   (20)   all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.

Food is very important. Everyone needs to _（1）_ well if he or she wants to have a strong body. Our minds also need a kind of food. This kind of food is   (1)  _. We begin to get knowledge even   (2)   we are very young. Small children are   (3)  _ in everything around them. They learn _  (4)   while they are watching and listening. When they are getting older, they begin to  (5)  _ story books, science books…, anything they like. When they find something new, they love to ask questions and   (6)   to find out answers. What is the best   (7)   to get knowledge? If we learn by ourselves, we will get   (8)   knowledge. If we are   (9)   getting answers from others and do not ask why, we will never learn well. When we study in the right way, we will learn more and understand better.

Computer games are popular all around the world. Many people   (1)  these games on the Internet. Games look more and more

   (2)   as computer technology improves. Many people describe playing computer games as   (3)  a new world. Some games let people   (4)  their own cities. Some games take people on journeys. Other games allow people to take over the Internet.

Games can   (5)  many positive effects. It can make help people make friends, learn to solve problems and make decisions. It can   (6)  help improve eye and hand movement. However, gaming can become a   (7)  .

People addicted to (沉溺于) computer games will find   (8)  thinking about playing all the time. And this can   (9)  neglect (忽视). People with a gaming addiction often   (10)  their studies, work, sleep, relationships, food, and family. They are often unable to   (11)  the amount of time they play. And uncontrolled playing can lead to other problems like debt. Many gaming addicts spend all their   (12)  on gaming.

  (13)  , there have been far worse cases of gaming addiction. It was reported that a man died while playing an Internet computer game   (14)  he had been playing the same game for 50 hours with few   (15)  .

Today, many more governments and doctors are trying to solve the problem of gaming addiction. More people are learning about the problem. More people are getting   (16)  . And more people are changing their lives. Some people might blame the game   (17)  for creating the problem of gaming addiction. However, some people think   (18)  .

“It would be easy for me to blame the game,   (19)  I know that was not the problem. I ran away from my problems. I   (20)  in an Internet world instead of directly working to solve my problems ” a game addict said.

Scientists find that hard-working people live longer than average men and women. Career women are   (1)   than housewives. Evidence shows that the    (2)   are in poorer health than the job-holders. A study shows that    (3)     the unemployment rate(失业率)increases by 1%, the death rate increases correspondingly(相应地) by 2%. All this comes down to one point: Work is helpful to health.

    Why is work good for health? It is because work    (4)    people busy,    (5)    loneliness and solitude(独居). Researches show that people feel unhappy,    (6)      and lonely when they have nothing to do. Instead(相反), the happiest are those who are    (7)    . Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a    (8)    between man and reality. By work, people   (9)   with each other. By activity, they find friendship and warmth. This is helpful to health. The loss of work   (10)   the loss of everything. It affects(影响) man spiritually and   (11)   him easily affected by disease.

   (12)   , work gives one a sense of fulfillment and a sense of     (13)   . Work makes one feel his value and status in society. When a     (14)    finishes his writing or a doctor successfully   (15)   on a patient or a teacher sees his students    (16)   up, they are happy   (17)   words.

From the above we can    (18)    to the conclusion that the more you work, the   (19)    and healthier you will be. Let us work hard, study well and    (20)     a happy and healthy life.

Do you see the glass as half-full rather than half-empt？Suchclichés（陈词滥调）are  (1)   questions, as researchers examine with great care the power of positive thinking. Research is proving that optimism can  (2)   you to be happier, healthier and more successful. Pessimism leads,  (3)  , to hopelessness, sickness and failure, and is linked to  (4)  , loneliness and painful shyness. If we could teach people to think more positively, it would be like protecting them against these  (5)   illnesses.

Your abilities count but the belief that you can succeed  (6)   the result. When things go wrong the pessimist tends to  (7)   himself. “I’m not good at this,” he says. “I always fail.” But the optimist looks for other  (8)  . Negative or positive, you are what you think. If people feel hopeless they don’t  (9)   to acquire the skills they need to succeed.

A sense of control is the real test for  (10)  . The optimist feels in control of his own life. If things are going badly, he  (11)   quickly, looking for solutions, forming a new plan of action, and  (12)  for advice. The pessimist feels like a toy of fate and moves slowly. He doesn’t seek advice, since he  (13)   nothing can be done. Many studies suggest that the pessimist’s feeling of helplessness  (14)   the body’s immune system. The pessimist doesn’t take good care of himself. Feeling passive and unable to avoid life’s  (15)  , he expects ill health and other misfortunes, no matter what he does. He eats junk food, avoids exercise, and  (16)   the doctor.

Most people are a(n)  (17)   of optimism and pessimism, but are in favor of one direction or the other. It is a pattern of  (18)   learned at our mothers’ knees. It grows out of thousands of cautions or  (19)  , negative statements or positive ones. Pessimism is a hard habit to  (20)   but it can be done. So, if you are a pessimist, there are ways....

Sometimes, we want to know what our lives are going to look like. We may want to know what gifts and   (1)   are going to be presented to us in the coming years  (2)   if our goals will be realized. Perhaps we feel like we need help to make a   (3)   and we want to know which choice will work out best. We may   (4)  fortune-tellers, our dreams, and many other sources in the hopes of   (5)   out what the future holds.  (6)   we would probably be overwhelmed(感到不知所措) if we knew everything to happen to us.

   Just think of your life  (7)  you've lived it up to this point. You have probably done more and faced more than you could have ever   (8)  . If someone had told you all the jobs and relationships you would
  (9)  when you were a child, you would have become overwhelmed. With your head full of information about the   (10)   you would have had a very  (11)   time experiencing your life in the present moment, which is where everything  (12)   happens.

   In many ways, not knowing what the future has  (13)   brings out in us the qualities we need to grow. It would have been difficult to   (14)  yourself to certain people or projects if you knew they wouldn't eventually   (15)  Yet, it was through your commitment to see them that you experienced the  (16)  
you needed to grow.  (17)   your life, it would likely be hard to say that   (18)   in your past should not have happened. In fact, your most challenging experiences with their expected lessons may have eventually  (19)   you the greatest rewards.

   Not knowing the future  (20)   us just where we need to be ---- fully committed and in the present moment.

 It takes plenty of time for some adults to try to stop children playing. They are usually people who think of play as being the   (1)   of work and therefore a waste of time. For humans, work is a way of getting food to eat, and like humans,   (2)   must spend time doing the  (3)   things. Regardless of this, children   (4)   playing, and so do other young animals. It is quite   (5)   to keep both a small child and a young cat   (6)   for hours with a piece of paper.

    Hunting may be the most obvious skill   (7)   in play, but it is far from being the only one. Lambs and goat kids play   (8)  , although as adults they will never   (9)   anything other than some grass. But for these young animals too,   (10)   is an important part of learning. Sheep and goats are   (11)   hill and mountain animals. Running and skipping exercise young legs and develop a strong sense of   (12)   that will keep them safe on the steepest rocks.

  (13)   animals’ play, children’s play is not so different.   (14)   trees and catching flies are not the most obvious training for the adult world, but the flexibility   (15)   in these activities is similar to that required of a bus driver or businessman.

What we know about animals shows us that playing is a very good way of   (16)  , so maybe one of the best ways for   (17)   to learn is also by playing. Children find playing is fun, but   (18)   notice that they are also learning at the same time. Most people continue to play games long after they have become   (19)  , and perhaps that is because we rely so much on our   (20)   to learn.

“In university open days with my daughter, I promised not to ask any questions — in case I asked embarrassing ones,” says Mike Nicholson, director of admissions at the University of Bath. Nicholson says he has seen some helicopter      (1)  in action, but was careful to make sure his own teenage daughter was not     (2)  by any overbearing interference (干预). They were able to come to a(n)   (3)  : he could ask questions cautiously, one-on-one, but not   (4)   his hand in the middle of a talk. “Students have to make the change from living at home to living at university and open days are part of the   (5)   he says. “It’s about   (6)   students to ask the questions, rather than the parents saying everything.”

Parental      (7)  in education can be good for students: if anything goes     (8)  further down the line, parents may be more willing to   (9)   It’s also more practical. Karen Darlow, whose son Henry now studies French and classics at Oxford, saw her   (10)   at the university’s open day as driver, note-taker and purchaser of lunch. “I think he was also   (11)   that I was coming because he’s quite shy,” she says. “It was a little bit of   (12)   support.” Most applicants attend open days when they’re in year 12, and parents can bring a practical   (13)   to the day. Many universities have parent zones to address the   (14)   of parents and careers.

  (15)   not everyone thinks having parents with them is a   (16)   idea: University of East Anglia student Alys Earl left hers   (17)   at home. “We’re adults, not year sevens,” she says. Another tip, from Bath’s Nicholson, is to   (18)   There’s value in allowing the students to go off   (19)  it helps their independence and gives them a chance to   (20)   themselves at the university.
