If you know something is bad for you, why can...

If you know something is bad for you, why can’t you just stop? After decades of research, scientists have found clues to why bad habits are so difficult to kick.　 1..

Too tired to drag yourself to the gym? Not enough time to squeeze in a swim?　 2. Short bursts of exercise can be beneficial too. For example, go for a shorter walk, but introduce some jogging in the middle. You can also walk faster between two landmarks, like trees. Gardening and climbing stairs count as well.

Not fancy eating vegetables? A 2019 survey found that only 29 per cent of adults ate the recommended five vegetables per day.　 3. “If you’re at a party and want to eat healthier vegetables instead of fattening foods, then mentally visualize yourself doing that. It does not necessarily work, but it certainly can help,” says a researcher.

4. Therefore，it’s better to eat earlier in the day when you’re more likely to burn calories. You can also go to bed sooner so that you have less opportunity to give in to the late-night snacks. Ideally, eat nothing between dinner and bedtime.

Being negative is one of the biggest barriers to maintaining good habits. Worse still, it can do harm to your sense of well-being generally.　 5. Whenever negative feelings pop into you head, try to fight the self-criticism by finding three positive thoughts, which in turn make your more emotionally intelligent.

A.Do remember that feelings are not facts.

B.Instead, stop eating just before you feel satisfied.

C.Overeating before bed proves harmful to your health.

D.Fitness doesn’t always have to involve long training periods.

E.A helpful technique is to imagine yourself in a tempting situation.

F.Now they’re developing strategies to break some of the bad habits.

G.Working out in the gym regularly will exercise your muscles and make you stronger.

If you know something is bad for you, why can’t you just stop? About 70% of smokers say they would like to stop. Drug and alcohol abusers (滥用者) struggle to give up the bad habits that hurt their bodies and destroy families and friendships. And many of us have unhealthy weight that we could lose if only we would eat right and exercise more. So why don’t we do it?

Some scientists have been searching for answers. They’ve studied what happens in our brains as habits form. They’ve found answers to why bad habits, once formed, are so difficult to kick. And they’re developing ways to help us make the changes we’d like to make.

Habits are a normal part of life, and are often helpful. “ We wake up every morning, shower, comb our hair or brush our teeth without being aware of it,” Volkow says. We can drive along familiar routes without really thinking about the directions. “When behaviors become automatic(不加思索的), it gives us an advantage, because the brain does not have to perform the action on purpose.” Volkow says. This frees up our brains to focus on different things.

One way to kick bad habits is to focus on your unhealthy habits. Then try your best to stop them. For example, habits can be linked in our minds to certain places and activities. You could develop a plan, say, to avoid walking down the hall where there’s a candy machine. Try to avoid going places where you’ve usually smoked. Stay away from friends and situations linked to problem drinking or drug use.

Another helpful way is to replace unhealthy habits with new, healthy ones. “It doesn’t work for everyone,” Volkow says. “But certain groups of patients who have a history of taking a drug can do something else like running and it helps them stay away from drugs.”

1.In the first paragragh the writer mainly wants to tell us ______.

A. we should stop something bad for us

B. most smokers would like to stop smoking

C. bad habits are really difficult to give up

D. eating right and exercise more can lose weight

2.Scientists studied what happened in our brains as habits form in order to______.

A. find answers to solve the problem

B. find ways to form good habits

C. kick their own bad habits

D. help us see how bad habits form

3. If you want to kick bad habits you’d better_______.

A. focus on them on purpose

B. go to the places linked with them

C. do something linked with them

D. ask your friends for help

4.What is the main idea of the passage?

A. Breaking bad habits.

B. Forming good habits.

C. Finding reasons for bad habits

D. Replacing bad habits with good ones.

Ever wonder why sometimes a hug is all you need ? You can’t explain it , but there’s just something comforting about being in your wife’s arms after a rough day or giving mom a hug after a long time apart .

A new study says the warm feeling in a hug is more than just skin deep . Researchers from the University of California , Berkeley believe that this loving feeling could have anti-aging benefits .

Oxytocin , sometimes referred to as the “ love hormone（荷尔蒙）” or the “ trust hormone , ” is responsible for those indescribable feelings we get when we’re bonding with a lover or a loved one .

Levels of the hormone drop as we age , and evidence suggests that could be a contributing factor to the deterioration of our bodies as we age . Muscle loss in particular is one of the major side effects of aging , with our bodies losing up to 5 percent of our muscle mass each decade past our 30s .

In the study , published in the journal Nature Communications , researchers injected oxytocin into older mice with muscle damage . The older mice had lower levels of the homeone than younger mice initially . But after nine days , the older mice who were given the hormone healed better than those who did not . In fact , their ability to repair muscle damage was up to 80 percent that of the younger mice .

The results were not only fast-acting , but provide hope for future uses of the hormone in a variety of anti-aging capacities . “ This is good because it demonstrates that extra oxytocin improves aged tissue stem cells（组织干细胞）without making muscle stem cells divide uncontrollably , ” study co-author Wendy Cousins said in a statement .

Previous uses of anti-aging molecules have also been associated with higher cancer risk , but researchers are hopeful that oxytocin can be useful in humans without this risk . In the future , researchers of Berkeley say oxytocin could be used to fight other age-related health issues by improving bone health and even being used as an alternative to hormone replacement therapy .

Now go out and give someone a hug .

1.According to the passage , oxytocin __________ .

A. decreases when people get older

B. creates loving feeling on the skin

C. leads to the great loss of muscles

D. can be used in humans without any risk

2.The underlined word “ deterioration ” in Paragraph 4 probably refers to the state of __________ .

A. getting fatter　　　　 B. becoming worse or less

C. growing stronger　　　 D. dividing uncontrollably

3.What can be learned from the research ?

A. All the older mice healed faster in the research .

B. Older mice healed better than younger ones after 9 days .

C. Extra oxytocin in older mice controlled muscle cell division .

D. Mice with oxytocin injection improved the ability to repair muscle damage .

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

A. When Do We Need A Hug ?

B. A New Anti-aging Product

C. Hugs Having Healing Power

D. How Can We Grow Muscles ?

You might not know it, but there is something wonderful at your fingertips. You can make people happier, healthier and more hard-working just by touching their arms or holding their hands.

Doctors say that body contact is a kind of medicine that can work wonders. When people are touched, the quantity of hemoglobin (血红蛋白)－a type of matter that produces the red color in blood increases greatly. This results in more oxygen reaching every part of the body and the whole body benefits. In experiments, bottle-fed baby monkeys were separated from their mothers for the first ten days of life. They became sad and negative. Studies showed the monkeys were more probable to become ill than other babies that were allowed to stay with their mothers.

Human babies react in much the same way. Some years ago, a scientist noticed that some well-fed babies in a clean nursery became weak. Yet babies in another nursery were growing healthily, even though they ate less well and were not kept as clean. The reason, he concluded, was that they often had touches from nurses.　　　　　　

Experiments show that most people like being touched. And nearly all doctors believe touch helps to reduce patients' fear of treatment. Of course there is time when a touch is not welcome. But even if we don't like being touched, a smile can make us feel better. Smiling increases blood flow and starts the production of "happy brain" chemicals. So let's have a big smile and don't forget to keep in touch.

1.Which of the following is NOT true?

A. Everyone knows that body contact can make people happier.

B. People may work harder because of body contact.

C. Your fingertips can do something.

D. People may not understand the importance of touching.

2.According to the passage _____.

A. human brains need oxygen and blood supply now and then

B. touches from doctors and nurses have nothing to do with treatment

C. new-born baby monkeys should stay away from their mothers

D. not all the people like being touched

3.The word "benefits" in the second paragraph probably means _____.

A. to be useful or helpful

B. to get something useful or helpful

C. to be ill

D. to be hurt

4.The best title for the passage might be _____.

C. Wonders of Touch    D. Touch or Not
