It is generally believed that humans can’t live without sleep. As any person suffering from lack of sleep knows, dark circles under the eyes usually stand out after a bad night’s sleep.
But why do people get these dark eye bags? The answer is both genetic (that is, relating to your DNA) and environmental (a result of your everyday living, such as rubbing your eyes or getting too little sleep), said Dr. Carol Clinton, a skin-care researcher in Dublin, Ohio.
But “the biggest reason is genes,” Clinton told Live Science. Eye bags are generally more noticeable in people who, because of genes, have thin or pale skin. When people are tired or very nervous, blood circulation in the eye area becomes slow, allowing blood to pool there, Clinton said. Capillaries（毛细血管）stand out, leading to dark eye circles, she said.
Besides, eye bags result from eyes’ fat moving forward. An age-connected increase in fat beneath the eyeballs leads to eye bags. “Anyway, when your eyes’ fat is moving forward, you may think about having an operation in that area,” Clinton said, “A person can get 9 hours of sleep a night, but still have eye bags because of a genetic development.”
In other cases, environmental problems cause eye bags. For example, allergies（过敏）—especially seasonal allergies—can cause capillaries to stand out. Getting too much sun can also damage and thin the skin, making dark circles under the eyes easy to see. Besides, eating salty foods can cause the body to hold more water, which makes eye bags worse, according to the Mayo Clinic.
1.In Clinton’s opinion, what is the main cause of the formation of dark eye bags?
A. Genes. B. Habits.
C. Age. D. The environment.
2.What can remove your eye bags according to the text?
A. Getting much sun.
B. Drinking plenty of water.
C. Having an operation on the fat in the eye area.
D. Slowing your blood circulation in the eye area.
3.What can we learn from the text?
A. It’s possible to change genes.
B. Rubbing your eyes might cause dark eye bags.
C. People with thick skin don’t get dark eye bags.
D. You can’t get dark eye bags if you get enough sleep.
4.What’s the best title for the text?
A. What Can You Do to Protect Your Eyes?
B. The Importance of Sleep to People’s Health
C. Several Measures to Remove Your Eye Bags
D. Why Do People Get “Bags” Under Their Eyes?

It seems that no one can live a happy life without friendship. While a great number of people expect others to be their friends, they don’t give friendship back. That is why some friendships don’t last long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.
Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest, you may lose your friend’s trust. Good friends always depend on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.
Sooner or later everyone needs understanding and help with each other. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so that you can understand the problem better.
No two friendships are exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.
1.Some friendships don’t last long because ________.
A. there are too many people who want to make friends
B. those who give others friendship receive friendship from others
C. some people receive friendship but don’t give friendship back

2.According to the passage, honesty is ________.
A. a necessary part of friendship B. more important than anything else
C. as important as money D. something impossible
3.Which of the following isn’t talked about in the passage?

C. Discussing your problems with your friends often helps to solve the problem.
