2、ys and legal holidays as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.RizlaredOnline games are addictive, but if children are taug

3、ht how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.AndrewGood policy. By limiting time spent on online games, kids

4、 can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time

5、 limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.PinkExcessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gami

6、ng industry should not put profit- flaking interests as its priority ( 优先事项) . They should act in a socially responsible way to provide an environment for children to ensure their well-being and development.LaurenThere would be a loophole(漏洞). Children could use their parents or other adults IDs to

7、avoid real-name registration, thus making it impossible to put this policy in effect.

10、ts have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles ar

11、e, for better and worse, representative of those of most of us. They tested the mens fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.Then, on two separate morning visits to the scientists lab, each man walked for an hour at an average speed that, in th

12、eory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started wal

13、king.Just before and an hour after each workout, the scientists took additional samples of the mens blood and fat tissue.Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skippe

14、d breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.But it was the effects deep within t

15、he fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the bo

16、dy and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.4. The un

Lifestyle is not as important as morning exercise.D. Physical exercise before breakfast is better for health.C Last nights meteor(流星) shower left

20、 many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valleys mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so

21、brightened by the citys lights that it darkened the light of the meteors passing overhead. “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointments.” Astronomers-scientists who study star

22、s and planets-have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it. There is yet a population besides

23、professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100 million birds a year througho

24、ut North America die in crashes with lighted buildings and towers.” Countless more animals casualties(伤亡）result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to

25、 light while sleeping can increase persons chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Obse

26、rvatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.8.It happened last night that A. the citys lights affected the meteor watching B. the meteors flew past before being n

27、oticed C. the city light show attracted many people D. the meteor watching ended up a social outing9.What do the astronomers complain about?A. Meteor showers occur less often than before B.

Lessen the chance of getting cancer B. create an ideal observation condition C. ensure citizens a good sleep at night D. enable all creatures to live in harmonyDIf you have a chance to take a walk in a park, look carefully at the people

30、walking their dogs. Youll probably find friendly-looking people with friendly dogs; quiet people with quiet dogs; large men with oversized dogs and long-haired women with long-eared dogs. As youve probably noticed, dogs and their owners look alike. Have you ever wondered why?These similarities are s

31、o common that researchers have tried to explain them. There are two theories (理论): the convergence (趋同) theory and the selection theory. The convergence theory says that as the owner and the dog spend more time together, they influence each other to the point where they grow similar. In other words,

32、 they “converge.” The selection theory, on the other hand, says that owners are interested in dogs that look like them, so they choose those dogs as pets.Recently, researchers at the University of California decided to test the two theories by taking pictures of 45 dogs separately from their owners.

33、 Then they asked some students to match the dogs photos with their owners. The students were quite successful with purebred (纯种的) dogs: they correctly matched 16 out of 25 with their owners. However, they had almost no success connecting mixed-breed (杂交的) dogs with their owners. When owners select a

34、 purebred dog, they can easily predict (预测) what it will look like later. But that is not true with mixed-breed dogs because its hard to predict what a mixed-breed dog will look like when it grows up. And since it was the purebreds not the mixed-breeds that looked like their owners, the research see

35、ms to prove the “selection theory”.But one bit of warning. Although many people look like their dogs, not all dog owners enjoy having the similarity pointed out to them. So, even if the similarity is amazing, dont go up to a stranger and say, “Wow, you look just like your dog!”12. According to the c

36、onvergence theory, dogs look like their owners because _.A. their owners choose themB. their owners love themC. the dogs are purebred and grow up as expected D. dogs and owners spend more time together13. According to the selection theory, why do dogs look like their owners?A. They influence each ot

37、her.B. They often do the same thing.C. Owners pick dogs that look like them.D. Dogs usually follow what their owners do.14. The writer write the passage to_.A. show the importance of having a dogB. introduce two theories about dogs and ownersC. prove the selection theory is correctD. show the differ

Purebred dogs have predictable appearance.D. Most owners prefer to have purebred dogs.参考答案：1-3DCB 4-7BABD 8-11 ACDB 12-15DCBC6学科网（北京）股份有限公司
