Early rising has many advantage. First, it helps us to keep health. We all need fresh air, and the air is freshest in the morning. Beside, we can improve our health by exercise regularly in the morning. Second, it can also benefits our study because in the morning we can lean more quickly. Third, it can make us to plan our work for the day. Only without a proper plan can we work well. Early rising can allow us enough time to get ready for your work. So we say that those who always gets up late should make an effort to get up early.
For more than six million American children, coming home after school means coming home to an empty house. All of them have something 1. common. They spend part of each day alone. They are called latchkey children, who look after 2. (them) while their parents work.
Lynette Smith was once the headmaster of a school. She said, “We had a school rule against 3. (wear) jewelry. A lot of kids had chains around their necks with keys fastened. I was 4. (constant) telling them to put them inside their shirts. There were so many keys. It never came to my mind 5. they meant.” Slowly, she learned they were house keys.
She and her husband began talking to the children. Fear is the 6. (big) problem faced by children at home alone. One in each three latchkey children were scared. Many had nightmares and were worried about their own 7. (safe).
The most common way latchkey children deal with their fears is by hiding. It might be in a shower still, under a bed, 8. in a closet. The second is TV. They’ll often play it at high volume. 9. Smiths learned it’s hard to get statistics on latchkey children. Most parents are unwilling 10. (admit) they leave their children alone.

Here’s how yo-yo dieting affects your body and your mind
Yo-yo dieting, also known as weight cycling, occurs when a person experiences periods of weight loss followed by weight gain followed by weight loss and so on and so on. The effects of this weight cycling are significant, even when the weight lost and gained is as little as 10 pounds. 1..
It can make you gain weight
While dieting may help you lose a few pounds at first, it only works temporarily. Your body responds to the lack of calories by turning to lean muscle mass for energy. Once you have returned to your normal eating habits, the weight comes back on –2..
3.
Yo-yo dieting may increase the risk for heart disease and sudden death in post-menopausal(绝经后期)women. Studies found that when normal-weight women experienced periods of weight cycling, they were 3.5 times more likely to have sudden death than women whose weight remained stable. In the same study, yo-yo dieting increased a woman’s risk of death by 66 percent.
It can be damaging to your skin
Dermatologist (a doctor who studies and treats skin diseases) Robin Evans weighed in on the effect that yo-yo dieting has on the skin. “The up and down weight losses and gains can have harmful effects on the skin especially on the face with stretching and contracting the skin,” said Evans. 4..
It plays games with your mind
Yo-yo dieting is hard on the body, 5.. Repeatedly gaining and losing weight can leave dieters feeling more depressed about their weight and losing self-belief as a result.
If you’re a yo-yo-dieter, talk to your health care provider about lifestyle changes that can help you maintain a stable and healthy weight for years to come.
A.It only works temporarily
B.It can damage your heart
C.but in the form of fat, not muscle
D.but it’s even harder on the mind
E.but with a smaller size, you will make yourself less friendly
F.The result ends up more wrinkles and an overall effect of aging the skin
G.We turned to the experts to find out how yo-yo dieting can affect your body and your mind
What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves – but man-made ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to copy this seemingly simple process.
The man-made leaf developed by Daniel Nocera and his partners at MIT can be seen as a special chip with catalysts (催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), which uses those two materials to produce electricity.
A man-made leaf is not a new idea. The first man-made leaf was invented in 1997 but was too expensive and changeable for practical use. The new leaf, on the contrary, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that a man-made leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera’s recent discovery of several powerful, new, inexpensive catalysts. These catalysts make the energy change inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the machine can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have enough pure water.
With the goal to “make each home its own power station” and “giving energy to the poor”, scientists believe that the new machine could be widely used in developing countries, especially in India and rural China.

Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer in ways that were never before possible.
Rishi Rawat teaches AI at the University of Southern California’s (USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast. Rawat provides information about cancer cells to a computer. He says this data helps the machine learn. “. . . You can put the data into computers and they will learn the patterns and the pattern recognition is important to making decisions.”
David Agus is another USC researcher. He says machines are not going to take the place of doctors. “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can’t recognize by itself. Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer.”
Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to better see the cells. That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns, or structures, and learn how the cells are organized.
The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes. “All of a sudden, we have the computing power to really do it in real time. . . We couldn’t have done this, we didn’t have the computing power to do this several years ago, but now it’s all changed.” Agus adds that the process could be done for almost no cost in the developing world. He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine.
The University of Southern California researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.
