As we know, Human beings each have unique brains. The brain is of the greatest importance to the body. It is the boss of the body．Your eyes，ears，nose，and skin tell your brain what is going on around you．Other parts of your body tell your brain what is going on inside of you．Your brain takes in the signals．It tells your body what to do with them．When you touch fire，your skin tells your brain that your finger is too hot．Your brain tells you to move your finger．All these happen very fast．Your brain also controls your breathing，blinking，and heartbeat．It controls your feelings and thoughts too．

　Humans have the most developed brain of all animals．Yet it is not the largest brain．The human brain weighs three pounds．The brain of an elephant weighs 11 pounds．So the largest brain is not always the best brain．In people，a larger brain does not mean a clever person．

1.What is the main idea of this passage?

2.What happens after the brain takes in the signals from the body?

3.What does “the boss of the body” mean?

4.Which brain is the most developed?

The human brain remembers negative experiences more easily than positive ones.Our brains have developed in this way because threats,like dangerous animals,have a more immediate effect on people's survival compared to positive things like food or shelter.As a result,you clearly know what makes you unhappy,but do you know what makes you happy?

Research suggests that our level of happiness is partly shaped by the choices we make.If you've been chasing wealth,fame,power and some material things,you may be looking for happiness in the wrong places.Psychologists suggest that the following habits can make people happier.

People who own close relationships tend to be happier than those who do not.The number of our friends is not important.What matters is the quality of our relationships.Relationships that bring happiness usually consist of the sharing of feelings,acceptance,mutual respect and trust.

People who exercise on a regular basis can improve both their physical and mental well-being.Some research has shown that exercise can be as effective as some medicine in treating depression.

If we are so interested in an activity,we may lose track of time,and we can be in a state of flow.The activity could be playing the piano,surfing the Internet or playing a game...People who experience flow in their work or life tend to be happier.

People are more likely to be happy if they know what their strengths are and can use them regularly.People are especially happy when they can set goals and use their strengths to achieve them.

People,who think positively by being grateful,mindful and optimistic,are more likely to be happy.Being grateful means being thankful.Being mindful means considering,focusing on,and enjoying the experiences of the present moment.Being optimistic means being hopeful about the future.

Recently, scientists are reported to have grown a living human “brain”. The team at Aston University in UK created tiny bunch of cells which act like a mini nervous system.

They believe it could help find a cure for worse mental conditions like Parkinson’s disease. Professor Michael Coleman is leading the research program. He explained, “We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works.” The experiment involves changing cells from a cancer tumor (肿瘤）and making them behave like brain cells.

Although far from finished, researchers hope the false brain cells will give them a greater understanding of how real brains work. This, in turn, could significantly further research into conditions which affect the brain. Neil Hunt, chief leader of the research group, said, “It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (痴呆).”

The technique could also provide a way to carry on animal test and is being supported by the Humane Research Trust (HRT). The scientists predict that over the next ten years a million people will develop dementia. Professor Coleman believes their findings could change this. He said, “We hope our research will provide scientists with a new and highly relational human experimental model to help them understand the brain better and develop new drugs to control the related disease. However, the biggest challenge at present is that we are greatly short of fund, which will slow our research.”

The hand, the eyes, and the brain work together to make human beings different from other animals. No other animals have all three parts to work together. No animals can do what human beings can do. Humans can do many things and feel many things with the hand. The hand can hold onto things and make things because the thumb(大拇指) works with the fingers. This fifth finger is strong. Most animals don’t have thumbs. The thumb can press against the other fingers. Without a thumb to press against the fingers, it is difficult to hold onto anything. The thumb and fingers can also fit the flat surface of a box and the curved (不平的) surface of a pencil. We can feel that something is hot or cold, soft or hard, smooth or rough. The hand, with thumb and fingers, is one of the best tools we have. Most animals see a flat picture. Their eyes can only see how high and how wide something is. Some animals see a different picture with each eye. Some don’t see in colour. Humans see one picture with both eyes working together. We can see how high and how wide something is. We can also see how far in front of or in back of something a thing is. The brain tells other parts of the body how to work. Some of the things the body does are automatic; that is, we don’t have to think about them. For example, we don’t have to think to make our heart beat or our stomach work. The brain tells the eyes and hands how to make useful and beautiful things. That is how human beings become tool makers and artists. That is how human can have richer and better lives than other animals.

We all know what a brain is. A doctor will tell you that the brain is the organ of the body in the head. It controls our body’s functions, movements, emotions and thoughts. But a brain can mean so much more.

A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If a family has many children but one of them is super smart, you could say, “He’s the brains in the family.” And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.

Brain trust is a group of experts who give advice. Word experts say the phrase “brain trust” became popular when Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues(问题)facing the U.S. These professors were called his “brain trust”.

These ways we use the word “brain” all make sense. But other ways we use the word are not so easy to understand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means to remove something by letting it flew away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a country’s most educated people leave their countries to live in another. The brains are, sort of, draining out of the country.

However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm is not an act of weather. It is a process of thinking creatively about a complex topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.

If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to make some accept new beliefs by using repeated pressure in a forceful or tricky way. Keep in mind that brainwash is never used in a positive way.

1.According to the text, if you’re the CEO of Bai Du you can be called 　　 .

A. the organ of Bai Du　　 B. the brains behind Bai Du

C. the brain drain of Bai Du　　 D. Bai Du’s brain trust

2.Roosevelt successfully won the election probably because 　　 .

A. he was the brains behind America　　 B. he got the help of word experts

C. he was smart at giving advice　　 D. he got his brain trust

3.From the passage, we can infer that 　　 .

A. brainy and brainwash are never used in a negative way

B. brainstorming is not a good choice for a political leader for lack of creativity

C. a country suffers a “brain drain” when educated people move to other countries

D. to drain a lake means to fill it with a lot of water

4.The author explains the “brain” expressions by 　　 .

A. using examples　　 B. making comparisons

C. making comments　　 D. analyzing origins

We all know the saying, “Nobody is perfect.” It has been planted in our brains since we were children, and of course, it is the truth. So if nobody is perfect, why do we have such a hard time admitting when we are in trouble or need help?

Like many other young people trying to get through their first year of college, I felt anxious, and it had its grips on me pretty tight. It began getting in the way（妨碍） of my life, and I had to sit down and tell myself that my behavior was not healthy and there was a solution. Finally, I decided to turn to therapy(精神疗法).

Therapy. It has such a negative stigma (污名), but why? Does going to therapy mean that you are failing as a person or that you cannot fix your problems on your own? No. Going to therapy means that you are strong enough to recognize that something inside your head is not working correctly, and you are brave enough to try to solve it.

After a couple of weeks, many parts of my life became so much clearer. I began to understand that I, myself, am my worst enemy, which was pretty frightening. But, although frightened, I knew that it was only I who could guide me towards feeling better, and that was extremely empowering.

I have been guided towards a healthier mindset, one that is positive and powerful. I have been able to understand that no matter what happens in my life. I will always be okay.

A lot of people do not understand that it is normal to have negative feelings and sometimes to feel like we have lost control over certain parts of our lives. Seeing a therapist can greatly change your way of thinking about something if you keep your mind open and I am so thankful that I decided to go and do something for myself.

So, if you are in need of help, you can go to therapy and then everything will be okay.

高一英语七选五中等难度题查看答案及解析

Human brains begin growing and developing at a very young age. They learn from the simplest experiences, which enable your children to be aware of the world. There’s no denying that outdoor play helps a lot!

Times when children have to wait for their turns on playground equipment and following the playground rules by sharing, all these form components of a healthy social-emotional development. Young children develop their social-emotional skills through practice and small steps over time.

As parents or caregivers, it is fairly simple to support your child’s social-emotional skills. Acts like holding him, touching him, and speaking to him and giving him loving care and attention are all helping factors. When you allow them freedom to play, it is important to follow their interests in helping build their social-emotional skills.

Difficulties in social-emotional skills can often lead to children having trouble when playing with other children. Becoming easily angry or not empathizing (理解) with other children are all signs that may point in this direction. This can in turn lead to them not empathizing with the needs of other children.

As for the development of cognitive (认知的) skills, these develop through practice and opportunity over time. And while some cognitive skills may be genetic, most are learned through real life situations. In other words, learning and thinking skills can be improved through experiences.

To enable them to learn, it is important that we are mindful of what our children are interested in. And this realization is only set in place once the child is given enough room and time to grow and explore.

Depriving children of such experiences can mean that they might struggle with higher- level thinking skills. And while it is normal to keep them safe, we forget that by rushing them and cutting down on play time, we’re actually causing more harm than good.

1.What can playing with other children greatly help children do?

A.Learn from other children.

B.Develop their social emotion.

C.Promote their personal hobbies.

D.Help them to control their emotion.

2.What usually brings trouble to a child while playing with other children?

A.Not understanding others.

B.Caring too much about others.

C.Lacking social emotional skills.

D.Being more selfish than selfless.

3.What does the underlined word “depriving” in the last paragraph mean?

A.Taking away.

B.Providing for.

C.Referring to.

D.Focusing on.

4.What is the main purpose of the text?

A.To call on us to promote children’s interest.

B.To show us the importance of social emotions.

C.To tell us how to improve children’s social emotions.

D.To persuade parents to allow their children to play outdoors.
