About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
The passage is mainly about _____________.

A.color and its surprising effects.
B.women being luckier than men
C.danger caused by color blindness
D.some information on color blindness

According to the passage, with the help of the “cones”, we can ___________.

A.tell different shapes B.see in a weak light
C.kill mosquitoes D.tell orange from yellow

Why do some people say it is safer to be driven by women?

A.Women are more careful.
B.There are fewer color-blind women
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.

Which of the statements about the color- blind is true?

A.Neither men nor women can see deep red.
B.All of them see everything in shades of green.
C.None of them can tell the difference between blue and green.
D.Not all of them have the same problem in recognizing color.

As the new term starts, freshmen around the world are asking the same question: how can I make the best of four years at college? The New York Times received suggestions recently from PhD students and seniors at some of the top universities . Here is their advice.
“Many young people today are raised in a protective cocoon(茧)”, wrote Tim Novikoff, a PhD student at Comell. “College is a time to explore the world beyond and a chance to learn new things about yourself. Take classes in different subjects. Try lots of different clubs and activities.”
Remember also to take some time away from campus, suggested Willie Lin, a student at Washington University. “If you spend all of your time in school, then it becomes too easy to let criticism from an unkind professor or a conflict with a roommate take up large proportions.
Try to find work assisting a researcher or a professor---this is the advice from Aman Singh Gill, a PhD student at Stony Brook University. And he also said, “With a window into the world of research, you will find yourself thinking more critically, accepting fewer states at face value and perhaps developing a brave sense of what you can accomplish.”
Many young people can’t imagine even a single day without devices such as computers and cell phones. But try to keep yourself off them, cautioned Christine Smallwood, a PhD student at Columbia University.
Start by scheduling a few Internet-free hours each day, with your phone turned off. It’s the only way you’ll be able to read anything serious. “This will also have the benefit of making you harder to reach, and thus more mysterious and fascinating to new friends and acquaintances(熟人),” she suggested.
The underlined sentence in Paragraph 3 means we should _________.

A.spend more time at school B.take some time out of school
C.listen to criticism more D.not argue with roommates

Who thinks it is important to consider something critically?

A.Aman Singh Gill B.Christine Smallwood
C.Tim Novikoff D.Willlie Lin

Talking behind someone’s back is considered to be rude and mean. Such a conversation can cover all kinds of criticism, from their looks to their work and personality.
The other day at lunch I was with a group of colleagues, and we were talking about our boss. She is the new headmaster of our middle school.
We talked about how kind she is to us. She handwrites notes to wish us happy holidays or to thank us for jobs well done. She checks on us when she knows we’re facing difficulties outside school with our health or with our families. We talked about the good role model that she is for the young women in our school and the fair but firm way she treats students and parents.
I thought about this after lunch. Sometimes we have the good fortune to be part of another kind of “talking behind someone’s back”. And too often when we say something good about someone behind their backs, they never know about it! That night, I sent her an email to report the conversation. She replied by saying how much she appreciated hearing about this, and how it made a bright spot in a tough week of testing.
Watch for your next opportunity to be the reporter! Make sure you tell them about the nice things said behind their backs! Because how will they know unless we tell them?

This year, the World Mental Health Day on Oct 10 was marked by the theme: “Depression: A Global Crisis”. According to the World Federation for Mental Health and the WHO, depression has moved beyond the medical domain(领域) to become a social problem. Statistics from the Beijing Suicide Research and Prevention Center show that of the 287,000 people who commit suicide in China every year, 70 percent are victims of depression.
“This equates to one depression victim taking their life every three minutes,” cited CCTV recently. According to the Beijing-based Capital Medical University, the number of depression patients has been on the rise in the past years and now accounts for 5 to 10 percent of the population, more than the global average of 5 percent.
Wang Shaoli, vice-president of Beijing Huilongguan Hospital, a medical center specializing in mental health, said that what makes depression so widespread is that everybody can get it.
“No one is immune to depression,” said Wang. “It has become a social problem because depression kills one’s social capabilities, such as communication, and leads to a negative social mentality.”
According to Wang, depression can be treated with medicine and early psychological consultation. The real problem is the lack of awareness surrounding the issue.
“People with mental health illnesses are discriminated against,” said Wang. “So they are reluctant to go to hospital and often keep the pain to themselves, which only makes matters worse.” Only one in 10 depression victims are properly treated in China, according to the Beijing Suicide Research and Prevention Center.
“When people get depressed, it becomes part of their thoughts, making them negative, even desperate,” said Wang. “And the ideas are difficult to change.” That’s why Wang suggests early intervention.
“Normally it takes about nine months to treat depression,” said Wang. “But in most cases, patients drop treatment half way when they feel some progress.”
How is Para1& 2 mainly supported when it tells that depression has become a social problem?

A.By giving data B.By making definition
C.By analyzing causes D.By making comparisons

A.people with depression are more likely to commit suicide.

If you live in America in the 21st century you'll probably have to listen to a lot of people tell you how busy they are. It's become the default response when you ask anyone how they are doing:"Busy!""Crazy busy!".It is,pretty obviously,a boast disguised as a complaint. And the common response is a kind of congratulation:"That's a good problem to have,"or"Better than the opposite."
Notice it isn't generally people pulling back-to-back shifts in the ICU or commuting by bus to three minimum-wage jobs who tell you how busy they are.What those people are is not busy but tired.Exhausted!Dead on their feet.It's almost always people whose busyness is purely self-imposed:work and obligations they've taken on voluntarily,classes and activities they've "encouraged" their kids to participate in.They're busy because of their own ambition or drive or anxiety,because they're addicted to busyness and dread that they might have to face in its absence.
Almost everyone I know is busy. They feel anxious and guilty when they aren't either working or doing something to promote their work.It's something they have chosen.Busyness serves as a kind of existential reassurance(令人安心的保证),a measure against emptiness,obviously your life cannot possibly be silly or tiny or meaningless if you are so busy,completely booked,in demand every hour of the day.
Idleness is not just a vacation.It is as necessary to the brain as vitamin D is to the body,and deprived of it we suffer a mental affliction as ugly as rickets.The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole,for making unexpected connections and waiting for the wild summer lightning strikes of inspiration."Idle dreaming is often the essence of what we do,"wrote Thomas Pynchon.Archimedes' "Eureka"in the bath, Newton's apple :history is full of stories of inspirations that come in idle moments.

A.they are really tired of their present situation
B.they are really proud of their present life
C.they are complaining about their current work
D.their life are full of all kinds of problems

The writer mentions Archimedes' "Eureka"and Newton's apple to show that________.

A.history is full of interesting stories

A.ambition B.anxiety C.busyness D.dread

From the article,we can infer that ___________________________________.

A.generally people pulling back-to-back shifts in the ICU tell you they are busy

C.all the kids are self-imposed due to the drive and motivation
