Children who spend more time outdoors may have a lower risk of becoming nearsighted, new research suggests.

In the study, researchers looked at about 1,900 schoolchildren. The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop nearsightedness during this time than those who had not been instructed to spend more time outdoors. Moreover, among the kids who did become nearsighted during the study, the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors.

The researchers selected six schools and required the children, whose average age was 7 at the start of the study, to attend one additional 60-minute class of outdoor activities during each school day for three years. The parents of these children were also encouraged to engage their children in outdoor activities after school, especially during weekends and holidays. The other half of the children, from another six schools, continued their usual activity patterns. After three years, 30.4 percent of the kids in the intervention(干预) group had become nearsighted, compared with 38.5 percent of the kids in the other group.

It is not clear exactly why spending more time outside would benefit children’s eyesight, the researchers said. However, some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine(多巴胺) of the eye. In turn, dopamine is known to restrain(抑制) the type of growth in the eye that is associated with nearsightedness.

Based on the new results, the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight. However, it’s important to protect kids’ skin and eyes from UV light, which can be damaging.

Camels are large animals living in dry areas. There are two species of camels; the Arabian camel with a single hump(驼背) from the dry desert areas of West Asia, and the Bactrian camel with two humps from Central and East Asia. Camels are over 7 feet tall and weigh over 1,600 pounds. They will live up to 40 to 50 years. Most camels are domesticated(驯化) and fed by people. Camels are plant-eaters.

Camels are very strong animals with wide, padded feet. They have thick leathery pads on their knees and chest. Camels have nostrils(鼻孔) that can open and close, protecting them from the desert environment. Bushy eyebrows and two rows of long eyelashes protect their eyes from sand. Their mouth is extremely tough, allowing camels to eat thorny(带刺的) desert plants. Their widened feet help them move without sinking into the sand. Their thick coats reflect sunlight, and also protect them from the intense heat from desert sand. Their long legs help by keeping them further from the hot ground.

Camels can go without food and water for 3 to 4 days. They do not store water in their humps as is commonly believed.The humps are actually a container of fat. Camels are incredibly well-adapted to their environment. When conditions heat up, camels can increase their own body temperature, which prevents sweating and therefore water loss. They may not sweat at all during the day.

Camels are sometimes called “ships of the desert” because people ride them around the hot, dry deserts of the world. However, the number of camels is becoming smaller for various reasons.

1.According to the passage, camels usually live in ________.

A. Asia B. Africa

C. America D. Australia

D. can manage without water

4.What will the author probably talk about following the last paragraph?

A. Ways to protect camels.

Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends.

My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him. He seemed unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard(警惕).

On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We talked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?

The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.

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.
