Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (脑内啡) — chemicals in the body that cause happiness — are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice.
Both mice and humans release high levels of endorphins and endocannabinoids after exercise, along with many other chemicals. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety.
But after being given a drug to block their endorphins the change. However, when their endocannabinoids were block with a different drug, their runner’s high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner's high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already well known that exercise is a highly effective way to get rid of stress or anxiety.
The UK’s National Health Service even prescribes (开药方) exercise to patients who are suffering from depression.
“Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can boost your mood if you have depression, and it’s especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is put on our running shoes.
1.What did scientists from German universities recently discover?
A.Working out is a highly effective way to treat depression.
B.The runner’s high could be caused by endocannabinoids.

There are times when I leave for my running-group sessions with little enthusiasm. It might be because I’m tired, or stressed, or don’t want to leave something else. But I’m the coach, so I can’t choose to give it a miss.
It was yet another cold, dark, wet evening and I wasn’t feeling the love as I gathered all the necessary equipment. No one in their right mind will come out in this weather, I thought. But when I turned into the car park, my headlights picked out runners making a dash through the rain to our meeting point, where others were already working out to stay warm, with chat, laughter and hugs. They, too, I realized, might be tired, stressed or busy. But, unlike me, they had a choice about whether to come running or stay at home. And that makes their decision to come---and to keep on coming---more encouraging. Then, I went home from the run feeling better than when I’d arrived.
I believe one of the strongest motivations(激励;动机) behind these runners’ decisions to come along is being part of a group. Belonging to a running community makes running greater than running itself. It’s no longer just a workout; it’s a get-together with friends, a laugh and a shared experience. It provides a chance to share your success and disappointments, to be congratulated and comforted, and, just as important, to congratulate and comfort others.
Research has long shown the possibility of staying motivated is higher when exercise takes place in a group. The reasons are many. A study at the University of Southern California found people enjoy physical activity more when they are with others and are more likely to keep it up over the long term. And research by Strava in 2017 found running in a group made runners go faster and further. Using data from 90 million runs taking place all over the world, Strava found that the average pace of runs taking place in a group was seven seconds per mile quicker than solo runs, and the distance covered was an average of 1.3 miles further.
I joke about people being more motivated to come to my running sessions by the tea and biscuits afterwards than by the running itself. It might be true, but it doesn’t matter. Those laughter-filled minutes are every bit as important as the running in between.
1.What can we infer from the first paragraph?
A.The coach was always enthusiastic.
B.The coach was never discouraged.
C.The coach was sometimes unwilling.
D.The coach was often worn out.
2.Why is being part of a group most motivational?
A.It needs a coach who can offer help.
B.It frees runners from boring daily work.
C.It helps members to beat their records.
D.It creates space for their communication.
3.That being in a group improves performance is proven by _______ .
A.taking a typical example B.performing an experiment
C.listing accurate data D.sharing his experiences
4.Tea and biscuits in running sessions are meant to _________ .
A.attract more runners from other groups
B.build up some strength before running
C.make his running group stand out of all
D.add more life to their running experience

Time is on your side
How frequently do you say “I don’t have time”? Quite often, I guess. Every time we say those words, they make us feel weak and out of control. You are in control of your hours and your life. 1.
I know it’s not as easy as simply turning off the TV. But here are two steps that will help you take back control and get time on your side.
★2.
Be honest: do you spend an hour or two visiting Weixin and QQ every day? Are you spending time with people that you don’t really like just to please them? Are there meetings you attend that you can politely refuse?
It’s time to get real about the hours that add up to a lot of dissatisfying nothing. Think how you can cancel daily activities that are not useful. 3.
★Change your language.
Words matter. They have power. Saying “I don’t have time” is an excuse for not wanting to do something. Here are some good, empowering alternatives (选择):
“I choose not to start that project until next year.”
“4.”
“I’d love to go out this weekend but have important work I need to do first.”
Get better at saying no. 5. Use little pockets of time (friend running late, car stuck in traffic, meeting ending 10 minutes early) to do some productive thinking. All these things can add up over time more than you believe!
A.Identify your blocks.
B.But you are likely wasting a lot of it!
C.I really don’t have enough time to do it.
D.Replace them with things that satisfy you.
E.Take no notice of all those unimportant messages on your phone.
F.I’d love to read that book — I’ll get to it after my homework is complete!
G.When you don’t have a plan for your life, someone else will plan it for you.

Cold Truths
Is there any truth behind the saying “You are what you eat”? We put this to the test by asking three people to open their fridge doors and talk about their lifestyles.1.Maybe you can recognize your own fridge here!
“You might find bean products in our fridge, but hamburgers? Never!”—Amy, Teacher
2. This means we don't eat meat, and any milk or cheese had better be dairy-free. We like cooking at home and make our meals from fresh, seasonal fruit and vegetables. If we have children, I want to bring them up just like us, but my husband says that everyone should be able to make their own lifestyle choices.
“3.”—Mike, Chef
With five children, we're one big family! My wife and I both work full-time, so life can get pretty busy! Like a lot of chefs I know, I don't really do much cooking at home. Sometimes I bring home food from the restaurant where I work. Once a week we do a big shop and buy a lot of frozen food. I know we should eat more fresh fruit and vegetables...4.
“There isn't really much in my fridge. I'm too busy and tired to cook at home!”—Ted, Doctor
There's not enough room to swing a cat in my small apartment, so I don't cook very often. My fridge is usually half empty and I'm often too tired to eat much anyway.5.. As a doctor, I know I had better change the way I eat, but I just don't have the time or the energy right now.
A.My husband and I avoid all animal products.
B.Can you guess which fridge belongs to which person?
C.But ready meals are so convenient for full-time workers.

E.My fridge is a total mess for all I do is party and hit the books.
F.I still don't think that anything can beat my mum's T-bone steaks.
G.Some evenings I'll have something quick like toast or even just a yogurt.

We all know that exercise is good for our health. To stay healthy, doctors suggest doing 150 minutes of moderate(适度的)exercise every week. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.1. Compared to non-runners, runners show 30% lower risk of death," researchers said.
2.Here are four commonly shared ideas among fitness experts to reduce the risk of injuries for people new to running.
• Take it easy.3. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance or speed. Muscles(肌肉)and joints(关节)need time to recover.
• Get good running shoes. There is no single best shoe for every runner. You should find the shoes that offer the best fit for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.
•4.Take some time after each run to write down notes about what you did and how you felt. Look for patterns, things that happen over and over again.
• Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some forms of cross training to improve muscle balance and to help you stay injury-free. For example, swimming, cycling and yoga are good exercises to combine with running.5.
A.Take good notes.
B.Running also may help you live longer.
C.Running takes a lot of time.
D.Running may be good exercise, but it can be difficult on the body.
E.As we all know, doing sports helps us teamwork.
F.These exercises are easier on the body.
G.Do not run too much, too soon or too fast.

Bringing up children is hard work, and you are often to blame for any bad behavior of your children. If so, Judith Rich Harris has good news for you. Parents, she argues, have no important long -term effects on the development of the personality of their children. Far more important are their playground friends and neighborhood. Ms. Harris takes to hitting the assumption, which has dominated(支配) developmental psychology for almost half a century.
Ms. Harris's attack on the developmental psychologists’ "nurture" argument looks likely to reinforce(加强) doubts that the profession was already having. If parents matter, why is it that two adopted children, brought up in the same home, are no more similar in personality than two adopted children brought up in separate homes? Or that a pair of identical twins, brought up in the same home, are no more alike than a pair of identical twins brought up in different homes?
Difficult as it is to track the clear effects of parental upbringing, it may be harder to measure the exact influence of the peer(同龄人) group in childhood and adolescence. Ms. Harris points to how children from immigrant homes soon learn not to speak at school in the way their parents speak. But acquiring a language is surely a skill, rather than a characteristic of the sort developmental psychologists hunt for. Certainly it is different from growing up tensely or relaxed, or from learning to be honest or hard -working or generous. Easy though it may be to prove that parents have little impact on those qualities, it will be hard to prove that peers have vastly more.
Moreover, mum and dad surely cannot be ignored completely. Young adults may, as Ms. Harris argues, be keen to appear like their peers. But even in those early years, parents have the power to open doors: they may choose the peers with whom their young associate, and pick that influential neighborhood. Moreover, most people suspect that they come to resemble their parents more in middle age. So the balance of influences is probably complicated. Even if it turns out that the genes they pass on and the friends their children play with matter as much as affection, discipline and good example, parents are not completely off the hook
1.According to Ms. Harris,______.
A.parents are to blame for any bad behavior of their children
B.children's personality is largely shaped by their friends and neighbors
C.nature rather than nurture has a significant effect on children' s personality development
D.parents will affect greatly the children's life in the long run

A. children are more influenced by their peers
B. identical twins raised in the same home are different in personality
C. twins raised in two separate families are different in personality
D. upbringing has a less significant effect on children’s personality development
3.According to Paragraph 3, we know that .
A. it is easier for children to gain a language at home
B. it is harder to follow the effects of parental upbringing
C. immigrant children avoid speaking the same way as their parents at school
D. it is proved that peers have a greater effect on children’s qualities
4.What does the author mean by saying parents are not completely off the look at the end of the passage?
A. Parents should control the situation.
B. Parents should give their way to children.
C. Parents should spend more time on children.
D. Parents should take on their responsibility.
