We all know the keys to living longer：eating healthily，exercising daily，and avoiding bad lifestyle habits，but do you know that practicing these simple steps when you’re 50 and older can add more years to your life？

According to a new research conducted by Harvard University scientists，adults who follow five healthy habits which include never smoking，maintaining a body mass index（BMI）（体重指数）below 30，exercising for at least 30 minutes a day，drinking alcohol only reasonably，and following a well-balanced diet，can add a decade or more to their lifespan.

The study，published in the American Heart Association’s journal Circulation，suggests that men over age 50 who follow these five lifestyle habits can add up to 12 years to their lives while women who follow these healthy habits can add 14 years to their lifespan. While the method of living a longer and healthier life hasn’t changed much over the years，this new information regarding the benefits of working out and eating healthily later in life is a bit of a breakthrough in terms of how we look at aging.

Modern medicine often treats the elderly with a more reactive approach，focusing on discovering and creating medicines and therapies to combat（防止）life-threatening illnesses like cancer and especially heart disease. According to scientists who conducted this study，the focus should be on preventative（预防的）measures，making sure aging adults are adapting healthy habits before they reach a stage in life when health issues normally arise.

It is very important to put prevention through diet and lifestyle changes first. Heart disease and cancer are the leading causes of death in the United States，while heart disease in particular can arise because of certain lifestyle habits. One of those habits is smoking，which scientists said was the biggest determining factor in a person’s lifespan. Researchers found that there was a direct connection between an adult’s risk of early death and his lifestyle habits，with those following all five of the healthy habits enjoying significantly longer lives.

   According to a recent report, about 15% of the people in the UK are members of gyms. But are they more likely to be fit?

A study found that gym members were 14 times more active than people who didn’t belong to any health club. Gym members did six hours more exercise a week, and this activity did make them fitter than non-gym members. They also spent less time sitting down every day than non-gym members. The results were the same for men and women.

The study included 405 people between the ages of 30 and 64, and the main characteristics of those who were gym members were the same as those who were not. ''But gym members did more training than non-gym members, '' said the lead author, Elizabeth Schroeder of the University of Illinois.

While it might seem clear that gym members exercising more are healthier than non-members, Schroeder says this has not been directly shown before. However, the study is only designed to show a tie between gym membership and more exercise. It may be that active people like to join gyms. In the study, people who exercised as much as gym members were also in good health.

You can get the same benefits wherever you exercise. This study shows a gym membership can make you do more exercise, but other research shows that exercising outside has other help. Outdoor activities can make you feel happy about life—especially if you run through a forest.

Outdoor exercise is also more enjoyable than going to the gym. The first five minutes of outdoor exercise is especially helpful in making people feel good. But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.

【小题1】What did the new study find out?

A．Gym members had healthier eating habits.

B．There were fewer women gym members than men.

C．Gym members did at least eight hours of exercise a week.

D．Gym members were more active than non-gym members.

【小题2】In the study, researchers studied ____________________.

A．some sports lovers

B．405 gym members

C．people from different age groups

D．30 gym members and 64 non-gym members

【小题3】Which of the following will Elizabeth Schroeder agree with?

A．Women should do more gym exercise.

B．We should be careful with outdoor training.

C．Outdoor exercise is better than gym exercise.

D．It is easier to keep exercising if you go to the gym.

   The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’

But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

【小题3】What is the function of the cornflour according to the passage?

A．To create a thick liquid.

B．To turn the water into solid.

【小题4】What is the author’s attitude toward the idea of humans’ walking on water?

A．It is risky but beneficial.

B．It is interesting and worth trying.

C．It is crazy and cannot become a reality.

D．It is impractical though theoretically possible.

   A new study says that the faces on Lego minifigures have become less happy and more often mad or sad. The study was designed to find out if the Lego characters have become grumpier over the years.

Christoph Bartneck works at the University of Canterbury in New Zealand. He loves Lego and even worked for the company in the 1990s. He worked with another researcher on the project. They looked at all of the 6,000 figures made between 1975 and 2010. They made a note of each figure’s facial expression: happy, grumpy, afraid, surprised or satL They discovered that while in 1980, all of the figures were described as “smiley”, and that by 1990, only about 80 per cent of them had been “smiley” . And by 2010, just 50 per cent of the figures had had a smile on their little plastic faces.

The researchers are wondering how the increasingly sad, angry and unhappy faces on the Lego figures will affect the children who play with them. “Children’s toys can have an important influence on children,” said Bartneck on the university’s website. While Lego hasn’t issued an official response to the study, Bartneck said he thought the reason why Lego was producing angrier-faced characters was that children wanted them. He said it was likely that people wanted Lego characters to have different expressions, rather than just being sunny all the time. He said most of the unhappy faces were on characters based on a specific theme such as Harry Potter or pirates (海盗).

Bartneck will present his findings at the International Conference on Human-Agent Interaction in Sapporo.
