According to a review of evidence in a medical journal， runners live three years   (1)  （long） than non﹣runners． You don't have to run fast or for long   (2)  （see） the benefit． You may drink， smoke， be overweight and still reduce your risk of   (3)  （die） early by running．

    While running regularly can't make you live forever ，the review says it   (4)  （be） more effective at lengthening life   (5)  walking， cycling or swimming． Two of the authors of the review also made a study published in 2014  (6)  showed a mere five to 10 minutes a day of running reduced the risk of heart disease and early deaths from all  (7)  （cause）．

    The best exercise is one that you enjoy and will do． But otherwise …it's probably running． To avoid knee pain， you can run on soft surfaces， do exercises to   (8)  （strength） your leg muscles （肌肉）， avoid hills and get good running shoes． Running is cheap， easy and it's always   (9)  （energy）． If you are time poor， you need run for only half the time to get the same benefits as other sports， so perhaps we should all give   (10)  a try．

Few people I know seem to have much desire or time to cook. Making Chinese   (1)  (dish) is seen as especially troublesome. Many westerners  (2)   come to China cook much less than in their own countries once they realize how cheap   (3)  can be to eat out. I still remember  (4)  (visit) a friend who’d lived here for five years and I  (5)  (shock) when I learnt she hadn’t cooked once in all that time.

  While regularly eating out seems to  (6)  (become) common for many young people in recent years, it’s not without a cost. The obvious one is money; eating out once or twice a week may be  (7)  (afford) but doing this most days adds up. There could be an even   (8)   (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in   (9)  (weigh) problems.

If you are not going to suffer this problem, then I suggest that the next time you go to your mum’s home   (10)   dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.

Diets have changed in China—and so too has its top crop. Since 2011,the country   (1)  （grow）more corn than rice. Corn production has jumped nearly 125 percent over  (2)  past 25 years, while rice has increased only 7 percent.

A taste for meat is  (3)  (actual) behind the change:An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn’s rise: The government encourages farmers to grow corn instead of rice

  (4)  (improve) water quality. Corn uses less water  (5)  rice and creates less fertilizer(化肥) runoff. This switch has decreased  (6)  (pollute) in the country’s major lakes and reservoirs and made drinking water safer for people.zxxk

According to the World Bank, China accounts for about 30 percent of total  (7)  (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government  (8)  (start) a soil-testing program  (9)  gives specific fertilizer recommendations to farmers — and 2011, fertilizer use dropped by 7.7 million tons.That prevented the emission(排放) of 51.8 million tons of carbon dioxide.China’s approach to protecting its environment while  (10)  (feed) its citizens ＂offers useful lessons for agriculture and food policymakers worldwide.＂ says the bank’s Juergen Voegele.

I'm not sure  (1)  is more frightened， me or the female gorilla（大猩猩）that suddenly appears out of nowhere． I' m walking on a path in the forest in the Central African Republic． Unexpectedly， I'm face﹣to﹣face with the gorilla， who begins screaming at  (2)  top of her lungs． That makes her baby scream， and then a 400﹣pound male appears．He screams the   (3)  （loud ）of all． The noise shakes the trees as the male beats his chest and charges toward me． I quickly lower myself， ducking my head to avoid   (4)  （look）directly into his eyes so he doesn′t feel   (5)  （challenge）．

    My name is Mireya Mayor． I'm a   (6)  （science）who studies animals such as apes and monkeys． I was searching  (7)  these three western lowland gorillas I'd been observing． No one had seen them for hours， and my colleagues and I were worried．

    When the gorillas and I frightened each other， I was just glad to find   (8)  （they）alive．True to gorilla′s unaggressive nature， the huge animal  (9)  （mean）no real harm．He was just saying： " I'm king of this forest， and here is your reminder! "Once his message was delivered， he allowed me   (10)  （stay）and watch．

Stress used to be an almost unknown word，but now that we are used to talking about it，I have found that people are beginning to get stressed about being stressed．

In recent years，stress(1)（regard）as a cause of a whole range of medical problems，from high blood pressure to mental illness．But like so many other things，it is only too much stress(2)does you harm．It is time you considered that if there were no stress in your life，you would achieve a little．If you are stuck at home with no stress，then your level of performance will be low．Up to a certain point，the more stress you are under，the (3)（good）your performance will be．Beyond a certain point，though，further stress will only lead to exhaustion，illness and finally a breakdown．You can tell when you are over the top and on the downward slope，by asking yourself (4)number of questions．Do you，for instance，feel that too much is being expected of (5)，and yet find it impossible to say no？Do you find yourself getting impatient of (6)（annoy）with people over unimportant things？…If the answer to all those questions is yes，you had better (7)（control）your stress，as you probably are under more stress than is good for you．

To some extent you can control the amount of stress in your life．Doctors have worked out a chart showing how much stress is involved in various events．Getting married is 50，pregnancy 40，moving house 20，Christmas 12，etc．If the total stress in your life is over 150，you are twice as likely (8)（get）ill．
