Science can’t explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people — half of them pet owners — while they performed 5minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松) around pets, says Allen, who thinks it may be because pets don’t judge.

A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn’t lose any more weight than those without dogs but, say researchers, got more exercise overall — mostly with their dogs — and found it worth doing.

1. What does the text mainly discuss?
A.What pets bring to their owners?
B.How pets help people calm down?
C.People’s opinions of keeping pets.
D.Pet’s value in medical research.
2. We learn from the text that a person with heart disease has a better chance of getting well if________.
A.he has a pet companion
B.he has less stress of work
C.he often does mental arithmetic
D.he is taken care of by his family
3. According to Allen, why did the people do better with pets around when facing stressful tasks?
A.They have lower blood pressure.
B.They become more patient.
C.They are less nervous.
D.They are in higher spirits.
4. The research mentioned in the last paragraph reports that______.

【推荐1】The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005.The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.

Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.

When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.

The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds. Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs. And it usually leaves a pleasant smell, which increases the likelihood that people will wash again.

Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.

1. We can learn from Paragraph 1 that _______.
A.the first Global Handwashing Day was held in 2005
B.many organizations support the idea of Global Handwashing Day
C.Global Handwashing Day was founded by many soap makers
D.the content of Global Handwashing Day is to wash your hand frequently
2. The underlined phrase “critical moments” in Paragraph 2 refers to _______.
A.the turning pointsB.schedules
C.the arrangement of a timeD.the necessary parts in health
3. The main purpose of the passage is to tell us ________.
A.hand washing is very importantB.to create a culture of hand washing with soap
C.germs can infect ourselves and othersD.soaps play an important role in everyday life
4. The last paragraph implies that ___________.
A.a soap is a kind of medicine to prevent a disease
B.it is important for children to wash hands in a correct way
C.Pneumonia kills about two million children each year
D.Diarrhea is the second leading cause of child deaths.

【推荐2】You get anxious if there is no Wi-Fi in the hotel or no mobile phone signal up the mountain. You feel upset if your phone is getting low on power, and you secretly worry things will go wrong at work if you are not there. All these can be called "always on" stress caused by smart phone addiction.

For some people, smart phones have liberated them from the nine-to-five work. Flexible working has given them more autonomy(自主权)in their working lives and enabled them to spend more time with their friends and families. For many others though, smart phones have become tyrants(暴君)in their pockets, never allowing them to turn them off, relax and recharge their batteries.

Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app-Moment-to monitor his usage. The app enables users to see how much time they're spending on the device and set up warnings if the usage limits are breached(突破). "Moment's goal is to promote balance in your life." his website explains. "Some time on your phone, some time off it enjoying your loving family and friends around you."

Dr. Christine Grant, an occupational psychologist at Coventry University, said, "The effects of this 'always on' culture are that your mind is never resting, and you're not giving your body time to recover, so you're always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer."

And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis(瘫痪)and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. "It actually makes it more difficult to make decisions and many do less because they're controlled by it all and feel they can never escape the office," said Dr. Christine Grant.

1. What's the first paragraph mainly about?
A.The popularity of smart phones.
B.The progress of modern technology.
C.The signs of "always on" stress.
D.The cause of smart phones addiction.
2. Kevin Holesh developed Moment to ______.
A.research how people use their mobile phones
B.help people control their use of mobile phones
C.make people better use their mobile phones
D.increase the fun of using mobile phones
3. What's Dr. Christine Grant's attitude toward "always on" culture?
A.Unclear.B.Positive.C.Doubtful.D.Critical.
4. According to the last paragraph, a great amount of data means ______.
A.we will become less productive
B.we can make a decision more quickly
C.we will be equipped with more knowledge
D.we can work more effectively

文章大意:这是一篇说明文。文章主要介绍了一些有助于睡眠的建议。

【推荐3】Many factors can interfere with a good night’s sleep — from work stress and family responsibilities to illnesses. You might not be able to control the factors that interfere with your sleep. However, you can adopt habits that encourage better sleep. Start with these simple tips.

1. Stick to a sleep schedule

Set aside no more than eight hours for sleep. The recommended amount of sleep for a healthy adult is at least seven hours. Most people don’t need more than eight hours in bed to be well rested. Go to bed and get up at the same time every day, including weekends. Being consistent reinforces your body’s sleep-wake cycle. If you don’t fall asleep within about 20 minutes of going to bed, leave your bedroom and do something relaxing. Read or listen to soothing music. Go back to bed when you’re tired. Repeat as needed, but continue to maintain your sleep schedule and wake-up time.

2. Pay attention to what you eat and drink

Don’t go to bed hungry or stuffed. In particular, avoid heavy or large meals within a couple of hours of bedtime. Discomfort might keep you up. Caffeine and alcohol deserve caution, too. The stimulating effects of caffeine take hours to wear off and can interfere with sleep. And even though alcohol might make you feel sleepy at first, it can disrupt sleep later in the night.

3. Create a restful environment

Keep your room cool, dark and quiet. Exposure to light in the evenings might make it more challenging to fall asleep. Avoid prolonged use of light-emitting screens just before bedtime. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs. Doing calming activities before bedtime, such as taking a bath or using relaxation techniques, might promote better sleep.

4. Limit daytime naps

Long daytime naps can interfere with nighttime sleep. Limit naps to no more than one hour and avoid napping late in the day. However, if you work nights, you might need to nap late in the day before work to help make up your sleep debt.

5. Include physical activity in your daily routine

Regular physical activity can promote better sleep. However, avoid being active too close to bedtime. Spending time outside every day might be helpful, too.

6. Manage worries

Try to resolve your worries or concerns before bedtime. Jot down what’s on your mind and then set it aside for tomorrow. Stress management might help. Start with the basics, such as getting organized, setting priorities and delegating tasks.

1. What can be learned from the passage?
A.It’s not hard to control the factors interfering with our sleep.
B.The longer we sleep, the better we feel.
C.It’s better to remain in bed when you fail to fall asleep.
D.Stress can contribute to bad sleep.
2. According to the article, which of the following encourages better sleep?
A.Do physical exercise before going to bed.B.Drink alcohol to get sleepy.
C.Avoid long naps during the day.D.Do some indoor activities.
3. This article is most likely to come from ____________.
A.a travel magazineB.an advertisement
C.a health magazineD.an informal letter
