【推荐1】More than one-third of adults in the United States are obese(肥胖)．In fact，over obesity has reached such proportions that one big-city mayor has gone about banning large-sized，sugary soft drinks and the First Lady has been on a campaign to control the dietary offerings in public schools．
Even many adults who do not fit the clinic definition of obesity are still overweight，and a large percentage are looking for the best ways to lose weight．
Reducing pounds largely comes down to the two-sided factors of diet and exercise．Not carrying out the first one enough，and not getting enough of the second one，ends up giving the individual a recipe for being overweight．
Advising someone to eat less and exercise more might be the easiest advice possible，but it’s also，partially，an oversimplification．Dieting has more to do with the types of food you eat than how much you eat．Reduce the amount of red meat in your diet．If you don’t want to eliminate red meat altogether，choose cuts of meat with less fat content．Limit your intake of salt and starches．If you’ve got to have potato chips alongside your sandwich at lunch，choose the baked potato chips that contain less fat than the deep-fried chips．You might find you’re really not sacrificing that much in terms of taste．
A diet rich in fruits，vegetables，egg whites，fish and nonfat dairy products will certainly aid in the mission of losing weight．Drink more water and less sugary drinks．If you have to have a soda，a diet soda is a better option，but seltzer is an even better choice than that．
It’s important—if not always easy—to make sure you get at least some physical activity each and every day．If your feet won’t allow for a regular jogging regimen，then make sure you take lots of walks．Next time you need to mail a letter，walk to the mailbox instead of driving．Try to work in a daily walk in your neighborhood．

【推荐3】Drinking a daily glass of wine for health reasons may not be so healthy after all, a new study from Washington University School of Medicine suggests.

Analyzing data from more than 400,000 people between ages 18 to 85, the researchers found that consuming one to two drinks four or more times per week-an amount considered healthy by current guidelines-increases the risk of early death by 20 percent, compared with drinking three times a week or less. The increased risk of death was consistent across age groups.

＂It used to seem like having one or two drinks per day was no big deal, and there even have been some studies suggesting it can improve health,” said first author Sarah M. Hartz. “But now we know that even the lightest daily drinkers have an increased death risk. ”

Although some earlier studies have linked light drinking to improvements   in cardiovascular(心血管的）health, Hartz said the new study shows that those potential gains are outweighed by other risks. Her team evaluated heart disease risk and cancer risk and found that although in some cases, drinking alcohol may reduce risk of heart-related problems, daily drinking increased cancer risk and, as a result, mortality risk.

The new study reviewed data from more than 700 studies around the world and concluded that the safest level of drinking is none. The Washington University team analysis focused on light drinkers: those who consumed only one or two drinks a day. The study focused on two large groups of people in the United States: 340,668 participants, aged 18 to 85, in the National Health Interview Survey, and another 93,653 individuals, aged 40 to 60 who were treated as outpatients(门诊病人）at Veterans Administration clinics.

Hartz thought that some doctors could recommend that people with family histories of heart problems have a drink from time to time, but in families with a history of cancer, physicians had better recommend quitting drinking.

1. What's the new finding of the study on light drinking?

A．It benefits heart health.

B．It is potentially unhealthy.

C．It is the main cause of cancer.

D．It harms only certain age groups.

2. How did researchers carry out the new study?

A．By collecting, clinical data.

B．By analyzing questionnaires.

C．By visiting hospitals personally.

D．By making an analysis of other studies.

3. What can we infer from the text?

A．Earlier studies are proved totally wrong by Hartz.

B．Hartz thought doctors should avoid suggesting drinking.

C．Hartz thought doctors should offer personalized suggestions.

D．The Washington University team surveyed about 700 people.

4. What can be a suitable title for the text?

A．Daily drinking, however much, adds to risk of death

【推荐1】Since his students began using Quizlet, the English teacher Tristan Thorne has noticed an improvement in their ability to learn and use new words. Quizlet is a learning app, a computer program you use on your mobile phone. It can help users build and test their knowledge of English words. Quizlet has words set for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.

Thorne teachers at Columbia University in New York City. Thanks to learning apps, Jeff Strack, another English teachers, has also noticed the improvement in his students’ ability to remember information. He teachers at Hostos Community College, also in New York. He and Thorne are part of a growing number of language educators adding mobile apps to their classes.

Strack and Thorne seem to agree that the days when teachers would not permit(允许) the use of mobile phones are gone. When they use apps, language learner communicate more differently than in a traditional classroom. Users act on or respond to something, instead of just listening to new information.

Thorne believes that apps can help learners become more active in learning. For example, each week, his students are required to add vocabularies to Quizlet for others to use. He says some apps also make it easy for students to know their language strengths and weaknesses.

The biggest improvement Strack has seen in his students is that they are much more active in whole-class or small-group discussions. “Apps let all students take part in the activity, whether it’s a game, quiz or practice activity.” he says.

Many existing learning apps are designed for students of all ages and levels. Some are designed for group activities. Some support independent learning. Still some are good for homework. Thorne says he especially likes Quizlet and three other apps: QR Codes, Socrative and Evernote.

1. What do Strack and Thorne do to improve their teaching?

A．They design learning apps for their students

B．They allow their students to use apps to study

C．They don’t allow their students to use apps after class

D．They order their students not to use mobile phones in class.

2. According to the text, how do the apps help the language learners?

A．They help language learners save much time and money

B．The help language learners remember their weaknesses

C．The help language learners improve their weakness

D．They help language learners take an active part in Learning

3. What can we learn about the exiting learning apps?

A．They have three types in total	B．There are too few to choose from

【推荐3】The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognize each other and is important to the formation of complex societies. So is the face’s ability to send emotional signals, whether through an unconscious reddening of face or a false smile. People spend much of their waking lives, in the office and the courtroom as well as the bar and the bedroom, reading faces, for signs of attraction, trust and cheat. They also spend plenty of time trying to dissimulate.

Technology is rapidly catching up with the human ability to read faces. In America, facial recognition is used by churches to track prayers’ attendance; in Britain, by shopkeepers to spot past thieves. This year Welsh police used it to arrest a suspect outside a football game. In China, it verifies the identities of ride-hailing (网约车) drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple’s new iPhone is expected to use it to unlock the home screen.

Compared with human skills, such applications might expand steadily in scale. Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode them. Although faces are unique to individuals, they are also public, so technology does not, at first sight, intrude (侵扰) on something that is private. And yet the ability to record, store and analyze images of faces cheaply, quickly and on a vast scale promises one day to bring about major changes to our understanding of privacy, fairness and trust.

Start with privacy. One big difference between faces and other biometric (计量生物学的) data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. FindFace, an app in Russia, compares snaps of strangers with pictures on VKontakte, a social network, and can identify people with a 70% accuracy (精确程度) rate. Even if private firms are unable to join the dots between images and identity, the state often can. Photographs of half of America’s adult population are stored in databases that can be used by the FBI. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens’ privacy.
