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.

EQ is a way of 【小题1】（measure） how a person recognizes emotions in himself or herself and others , and makes these emotional states work better as a group or team. IQ is a value that 【小题2】（indicate） a person's ability to learn, understand, and apply information and skills in a meaningful way. The major 【小题3】（differ）between EQ and IQ is what part of a person's mental abilities they measure; understanding emotions or understanding information.

According to some 【小题4】（theory）of brain function, a high EQ means someone is self-confident ,self-aware, and able to handle difficult emotional experiences. It is often tied directly 【小题5】 the degree of success a person may have in the workplace and in 【小题6】（person）relationships. People with high EQs can often better recognize and control their own emotions, and recognize  emotional states of others 【小题7】（adjust）their behavior accordingly.

A person's IQ, on the other hand, measures concepts like logical reasoning and math skills rather than creative potential or emotional abilities. People with high IQs may be able to learn certain subjects very quickly and make connections between ideas 【小题8】 will be missed by others. They often have great academic success, 【小题9】 they may struggle to find classes that challenge them. The ability to acquire knowledge does not 【小题10】（necessary）mean people can recognize and manage their own emotional states , however.

   Across Britain, burnt toast will be served to mothers in bed this morning as older sons and daughters rush to deliver their supermarket bunches of flowers. But, according to a new study, we should be placing a higher value on motherhood all year.
Mothers have long known that their home workload was just as heavy as paid work. Now, the new study has shown that if they were paid for their parental labours, they would earn as much as $ 172,000 a year.
The study looked at the range of jobs mothers do, as well as the hours they are working, to determine the figure. This would make their yearly income $ 30,000 more than the Prime Minister earns.
By analysing the numbers, it found the average mother works 119 hours a week, 40 of which would usually be paid at a standard rate and 79 hours as overtime. After questioning 1,000 mothers with children under 18, it found that, on most days, mums started their routine work at 7am and finished at around 11pm.
To calculate just how much mothers would earn from that labour, it suggested some of the roles that mums could take on, including housekeeper, part-time lawyer, personal trainer and entertainer. Being a part-time lawyer, at £ 48.98 an hour, would prove to be the most profitable of the “mum jobs”, with psychologist (心理学家) a close second.
It also asked mothers about the challenges they face, with 80 percent making emotional demand as the hardest thing about motherhood.
Over a third of .mums felt they needed more training and around half said they missed going out with friends.
The study shows mothers matter all year long and not just on Mother’s Day. The emotional, physical and mental energy mothers devote to their, children can be never-ending, but children are also sources of great joy and happiness. Investing (投入) in time for parenting and raising relationships is money well spent.
【小题1】How much would a mother earn a year if working as the Prime Minister?

A．£ 30,000.	B．£ 142,000.
C．£ 172,000.	D．£ 202,000.

【小题2】The biggest challenge for most mothers is from .

A．emotional demand	B．low pay for work
C．heavy workload	D．lack of training

【小题3】What is stressed in the last paragraph?

A．Mothers’ importance shows in family all year long.

B．The sacrifices mothers make are huge but worthwhile.

C．Mothers’ devotion to children can hardly be calculated.

D．Investing time in parenting would bring a financial return.

【小题4】What can we conclude from the study?

A．Mothers，working hours should be largely reduced.

B．Mothers should balance their time for work and rest.

C．Mothers’ labour is of a higher value than it is realised.

D．Mothers should be freed from housework for social life.

Global warming could make humans shorter, warn scientists who are said 【小题1】（find）evidence that it caused the world’s first horses to shrink nearly 50 million years ago.

In fact, a team from the universities of Florida and Nebraska says it has found a link between the earth 【小题2】（heat）up and the size of mammals — horses. The scientists used fossils to follow the evolution（进化）of horses from their earliest 【小题3】（appear）56 million years ago.

“As temperatures went up, 【小题4】（they）size went down, and vice versa; at one point they were as small as a house cat,” said Dr. Jonathan Bloch, curator of the Florida Museum of Natural History. The scientists say that the current warming could have the same effect 【小题5】 mammals — and could even make humans 【小题6】（small）.

Horses 【小题7】（start）out small, about the size of a small dog like a miniature schnauzer.【小题8】 is surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that 【小题9】（exact）agrees with the global warming event. “It had been known that mammals were small when it was warm,【小题10】 we hadn’t understood that the temperature really was driving the evolution of body size,” Dr. Bloch said in the Science journal.

   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!
