Why do we dream?It's a question researchers have been studying for years. Now new research suggests that some dreams may result from the brain's effort to keep learning, even as we sleep.
In a study in Boston, 100 volunteers were trained for an hour on a maze (迷宫).They tried to find their way through the difficult puzzle as quickly as possible. Then half of the volunteers were allowed to sleep for 90 minutes. The other half stayed awake, reading or relaxing. The ones who slept were asked to describe their dreams when they woke up.
After the rest, the volunteers were asked again to solve the maze. Those who hadn't slept showed no improvement or did even worse after the break. Sleepers who didn't report any maze related dreams did better but showed only a little improvement. However, four nap-takers who reported dreaming about the maze showed a surprising improvement. They scored 10 times higher after sleeping and dreaming about the maze.
Even though the number of dreamers was small, the researchers noted that the gap in learning between the dreamers and non-dreamers was so wide that the finding was significant (有意义的).
The dreamers had all performed poorly on the test before dreaming about it. That suggests that struggling with a task might be the trigger that leads the sleeping brain to focus on it and work on how to deal with it.
“It's almost as if your brain is going through everything that happened today,”Dr Stickgold,a scientist at Harvard Medical School, said. “The things you're obsessed (迷住) with are the ones that your brain forces you to continue to do with.”
1.What's the best title for this passage?

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.
“Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status,” said Professor Ryan.
Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.
But in a former experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship.
Professor Ryan’s recent experiment used 62 men and women aged 20 to 37.
Half of the participants(参与者)received oxytocin. The other half received placebo (安慰剂).
After a week, the two groups switched with participants. They went through the same procedure with the other material.
Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.
The results indicated that, after treatment with oxytocin, men’s ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.
Professor Ryan thus concluded: “Our experiment proves that the hormone oxytocin can raise people’s abilities to better distinguish many kinds of social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal.”
1.What causes men and women to behave differently according to the text?
A. Placebo. B. Oxytocin.
C. The gesture. D. The social status.
2.What can we learn from Professor Ryan's former experiment?
A. Oxytocin affects our behavior in a different way.
B. Our body lets out oxytocin when we are deep in love.
C. Our body produces oxytocin when we feel unhappy about others’ success.
D. Oxytocin improves our abilities to understand people's behavior differences.
3.Why did Professor Ryan conduct the recent experiment?
A. To test the effect of oxytocin on the ability to recognize social interactions.
B. To know the differences between friendship and competition.
C. To know people’s different abilities to answer questions.
D. To test people’s understanding of body language.
4.The underlined word “distinguish” has the closest meaning to ______.
A.accept B.discover C.differ D.explore
5.The author develops the text by______.
A. explaining people’s behaviors
B. describing his own experiences
C. distinguishing sexual differences
D. discussing research experiments

Why do people work? Of course, you may have asked yourself the same question as why you have to work. “Self-interest” in its broadest sense, including the interests of family and friends, is a basic motivation(动力)for work in all societies. But self-interest includes more than providing for living or getting wealth that people usually think. For example, a sense of duty, a feeling of competing, and a pleasure in working are other reasons for working. Studies show that most of Americans would continue to work even if they have had enough money to live comfortably.
When people work, they gain a contributing place in society. The fact that what they receive pay for their work means that what they do is needed by other people and what they are doing is necessary to society. Work can also place people in the larger class of society and provide all kinds of identities (身份) for them. In the United States, it is a cruel public fact that to do nothing is to be nothing and to do little is to be little. Work is commonly seen as the measure of an individual (个人).
Some scientists have shown some of the ways that work has effect on our lives. Generally, people who always do their favorite work are more open to new ideas and easier to get along with others, and as parents they pass these characteristics on to their children. Our work then is an important social thing that makes us know who and what we are.
64. Generally, people work for _____.
A. self-interest B. family C. earning a living D. the country
65. In the passage, “what they receive pay for their work” means _____.
A. that the work of the worker is recognized by society
B. what they do is needed by other people

66. In the last paragraph, we can conclude that the author thinks ____.
A. that work can make the worker rich
B. that work can affect their lives
C. that work can make the worker tired
D. that work can make the worker know the world well
67. The title of the passage is “______”.

If you have a dream
What do you dream about? There have been so many times when I’ve come back to Thomas Edison’s wise words: “When you have exhausted all possibilities, remember this – you haven’t.”
If there is a dream in your heart, you should dig it and shine a little light on the vision(视野). This time, instead of looking at it as impossible, start thinking freely: 1.?
If you have a dream…
2.. Seeing it on paper will help you see the possibility. It will be a daily reminder to work on your dream.
Tell someone. 3.. Later on, you’ll need someone to poke holes(指出漏洞)in your dream and help you make it into something that makes sense in the real world. But right now, you just need someone who will give you a big hug and tell you not to stop believing.
Do one thin g that will bring you closer to your dream. Read a book about the subject of your dream. Email someone who is living your dream and ask him or her what’s the one thing someone just starting out can do to move forward. 4.
Your dream might sound crazy or impossible, and that’s OK. 5.. 5 or 10 years may sound like forever, but if you were directing some of your resources(资源)towards your dream each day, wouldn’t those years be more enjoyable?
A. Ask for help
B. Write it down
C. Start now by doing one thing
D. Can you work hard to make your dream come true
E. The right someone is a loving, kind person you trust
F. It may take some time to make your dream come true
G. What changes could you make in your life to give your dream a chance
