A new study shows women need 60 minutes to exercise a day to stop weight increasing if they have a normal diet.

   The findings suggest women need more exercise than the current federal guidelines (聯(lián)邦指南) of 150 minutes a week,or 30 minutes five days a week.

   The study is being published in the March 24/31 edition of the Journal of the American Medical Association.

   “I don't want people to throw up their hands and say,I can't do it ,” said Dr Min Lee,the study's lead researcher.

   Women at a normal weight who have a normal diet can beat middle-age weight gain by working out intensely (高強(qiáng)度) for 30 minutes a day,whether by running,cycling,swimming laps or working out at a gym. Weight gain can also be prevented with 60 minutes of moderate activity,such as walking,a leisurely bike ride or playing catch.

   Overall,women gained an average of 5. 7 pounds in the study. However,those who were of normal weight,kept their weight if they exercised for 60 minutes a day. Women who exercised less generally gained weight. Dr Lee said for overweight women,60 minutes of exercise a day wasn’t enough to keep weight,suggesting cutting the calories (熱量) .

   A. Yes,it is. B. No,it isn’t.

閱讀提示：本文介紹一項(xiàng)新的研究結(jié)果：隨著女性年齡的增長，在正常飲食的情況下，她們需要每天進(jìn)行60分鐘中等強(qiáng)度的運(yùn)動(dòng)，才能避免體重增加。因此對(duì)于婦女來說，要想保持一個(gè)良好的體型，必須進(jìn)行足夠的運(yùn)動(dòng)。

   Some of the factors which make our lifestyle unhealthy are as follows：

   Too much junk food is being put into our hands especially in children's hands. Junk food which is full of fat increases blood cholesterol(膽固醇) levels and increases the risk of heart disease and some cancers.

   Life is full of stress. Modern life is full of trouble,deadlines. Work can be stressful,whether in an office,a factory,or a school. For many people,stress is everywhere and it has become a way of life.

   Western culture is generally dependent on medical drugs and people don't know that medical drugs’ side effects are dangerous to their health. In the world today,many people seem to think that they just want medicines and drugs to solve their health problems;they believe they can always ask medicine for help. But what they do not know is that these medications may have potential adverse reactions (潛在的不良反應(yīng)) . Some drugs are harmful to your liver and do crazy things to your health;perhaps you have those little poisons without considering what they are doing to your body.

   Exposure to pollution and toxic wastes such as poisonous agents from the household items does harm to your health. Our bodies are absorbing (吸收) the harmful chemicals surrounding the environment today. It is thus imperative that we clean up our living environment as much as possible. Those regular detergents,soaps,shampoos,toothpastes and perfumes that we use today contain many chemicals which are toxic to our bodies,some even carcinogenic.

   Less exercise. Exercise always improves our health level. There is no doubt about it. But we don’t exercise enough. We are too busy.

1. In the world today,many people depend on medical drugs,why?

2. What's the Chinese meaning of the underlined word household in the fifth passage?

3. How many factors make our lifestyle unhealthy?

4. What is the article about?

   Beijing is an old capital city developing at a fast pace. The Forbidden City is the ideal place for you to begin your exploration of Beijing by opening its mysterious (神奇的) face. With over 9 ,000 rooms and over 250 acres (英畝) ，this large palace building was built between 1406 and 1420.

If you are a non-group tourist,I suggest you rent a multilingual guide recorder either at Meridian Gate (southern gate of Forbidden City) or the Gate of Divine Prowess (Northern gate of Forbidden City) and return it when you finish your Forbidden City Tour.

   There is a fish called the black spot angelfish,which can change from female (雌性) to male (雄性) . No,it cannot do it by simply wishing to become male. The change happens for a specific reason.

   The angelfish live in groups. And each group has one male fish,which is blue in color,and four female fish,which are yellow in color.

   The male angelfish is the strongest and largest member of the group. He is the one who protects and looks after the females and acts like their “safety guard”. When the male dies,the group needs a “safety guard”. This is when the largest female fish in the group begins to change its appearance.

   She begins to grow larger in size. After a week,she starts changing color,from yellow to blue. Slowly? the changes take place. She begins behaving like a male. Two weeks later,black spots appear on her body. This shows that the change is complete. She is now completely male!
