【推荐1】You probably know that exercise is the key to reducing depression, but you might not know why. Here are some tips for exercising when you’re depressed.

Change your view of “exercise”.

Forget “exercise”. Instead, think “being active” or “having fun”.     1     Besides, it gives you a bigger benefit.

    2    

Taking part in physical activities with others supports you in doing those activities. Ask friends what activities they’re doing or they would like to start doing, and join them. Other choices include hiring a personal trainer, joining an exercise group or going to a class.

Try an experiment.

    3     Or go to the gym every Monday, Wednesday and Friday. Even if you’re feeling too tired to do any actual exercise, still go to the gym, park your car, walk in, change into workout clothes, and pick up a 5-pound weight. If you’re really so tired that you don’t want to do anything else, that’s totally fine.

Take it outside.

Nature has a great effect on our feeling and decreases depressive symptoms. Even just looking at images of lakes and trees helps.     4     Or walk on a treadmill (跑步机) by a window.

Tie it to a goal.

Korb said, “When you connect your exercise to a long-term goal, it helps your brain forget momentary discomfort and makes your exercise more satisfying.” For example, Korb started getting active because it made playing sports more enjoyable. Figure out what’s truly important to you.     5    

A．Move with someone else.

B．Sign up and go to exercise classes.

C．It’s a lot easier to do something simple.

D．Remind yourself of your goal regularly.

E．Remember your partner to keep you company.

F．Take a walk around your neighbourhood or a local park.

G．This increases your chances of actually moving your body.

【推荐2】Studying abroad is full of adventures-everything is different and exciting. How can you adjust to the new environment soon? Homestay is a great way to get to know the culture from a firsthand aspect. Here are some tips on how to enjoy a successful homestay.

Bring a thoughtful gift.

    1     Instead, a little souvenir (纪念品) from your home country is a great choice. Besides, it will help your hosts remember what an awesome family member you were.

Respect the schedule.

Even though you’ve paid for your stay, you’re still part of a family that is not yours - respect their schedules. If the meals are at 7 p. m., make sure you are on time.     2    

Attend the family meals.

Most host programs will give you the choice to include meals in your homestay. It’s highly recommended that you join your host family for at least one meal each day     3     You can also enjoy the conversations that meals inspire

Be fair and honest when problems arise.

    4     Nobody can avoid it. In case there’s a major trouble that bothers you, try to talk to the family first. Be aware that it might take some time to get used to each other - not just for you but also for the host family.

    5    

When it comes time to leave, you might be feeling some relief about getting back to a more familiar home. Do remember to make an effort to express your thanks to the family for let-ting you into their home and sharing their lives with you.

A．Show great relief before you leave.

B．Express your gratitude before leaving.

C．Lies can only make things much worse.

D．This can help you taste homemade local food.

E．You don’t have to spend a lot of money on the gift.

F．Whenever people live together, there’s room for disagreement.

G．You must let your host family know in advance if you can’t arrive on time.

【推荐3】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
       Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided.     1    
Write it out
       You can also check a math problem by writing everything out on paper.     2     Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
    3    
       Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem — subtraction (减法) — to determine whether or not your answer is the correct one.
Plugging in
       You may find that a variable (变量) isn’t good enough or have a problem where you have to solve for a variable.     4     This is the only real way to assure yourself that the answer you’ve found is correct.
Check for a reasonable answer

    5     For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.

A．Do the opposite

B．Correct the answers

C．Plug the variable in the equation (方程) to check it out.

D．Therefore you’ll improve your grades, as well as your math skills.

E．It also helps you to figure out everything after you have already finished the test.

F．If the result of a problem seems to make no sense, it indicates that the answer is incorrect.

G．This helps you to know what information you have and what information you need to solve.

【推荐2】How to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else).Registered dietitian(营养专家) Barbara Morrissey suggests that a few simple rules can help.

“Go for nutrient dense foods that contain a multiple of nutrients, ”she suggests, “For example, select whole wheat bread as a breakfast food, rather than coffee and cake.Or drink orange juice rather than orange drink, which contains only a small percentage of real juice------the rest is largely colored sugar water. You just can't compare the value of these foods, the nutrient dense ones are so superior,” she emphasizes.

Morrissey believes that variety is not only the spice of life; it's the foundation of a healthful diet. Diets which are based on one or two foods are not only virtually impossible to keep up the strength, they can be very harmful, she says, because nutrients aren’t supplied in sufficient amounts or balance.

According to Morrissey, trying to find a diet that can cure your illnesses, or make you a super woman is a fruitless search. As women, many of us are too concerned with staying thin, she says, and we believe that vitamins are some kind of   magic cure to replace food.

“We need carbohydrates(碳水化合物) protein and fat---they are like the wood in the fireplace. The vitamins and minerals are like the match, the spark, for the fuel,”she explains, "We need them all, but in a very different proportion. And if the fuel isn’t there, the spark is useless.”

1. From the first paragraph we know that working women ______.

A．think cooking is especially complicated

B．are likely to eat healthfully

C．are busy and not interested in cooking

D．do not share the same views with registered dietitians

2. In Paragraph 4, the underlined phrase means   ______.

A．a diet serving as medicine

B．a search for a diet without fruits

C．a research on a fruitless diet

D．an effort with no results

3. Many women take it for granted, according to the passage that ______.

A．lack of variety in diets leads to staying thin

B．staying thin and healthy are both possible

C．a balanced diet can result in being fat

D．vitamins are some kind of substitutes for food

4. By the sentence"if the fuel isn't there,the spark is useless"in Paragraph 5, the author means ______.

A．carbohydrates, protein and fat are   enough to support a human life

B．vitamins and minerals are virtually of no value

C．carbohydrates, protein and fat are as important as vitamins and minerals

D．without carbohydrates, protein and fat,vitamins and minerals are of no use

【推荐3】You know eating fruit and vegetables is helpful. But did you know it can also make you look good?

People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. Scientists at St Andrews University found eating them subtly increased yellow and red pigments in the volunteers’ skin. They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks.

Increasing their intake of greens by 2.9 portions a day was found to make the person look healthier and an extra 3.3 portions could enhance their attractiveness, when their photographs were rated by others.

Fruit and vegetables are rich in carotenoids (类胡萝卜素), which are known to protect against cell damage from pollution and UV rays, and can also prevent age-related diseases including heart disease and cancer.

But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange, it was not known a small increase was perceptible to others and was seen as appealing.

A camera measured changes to the skin redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident at three weeks. Using light sensors, the researchers showed these red and yellow hues were linked with the levels of carotenoids in their skin.

There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene (番茄红素) which gives tomatoes and red peppers their red color and beta-carotene found in carrots as well as broccoli (西兰花), squash (南瓜), and spinach (菠菜).

Skin color is also affected by chemicals called polyphenols (多酚), found in apples, blueberries and cherries, which cause blood rush to the skin surface.

1. From the passage, we learn that pictures were taken ________.

A．three times using a special camera every three weeks

B．twice using a sensitive camera every six weeks

C．by 35 people when they ate fruit and vegetables

D．by 35 people while being monitored to compare the changes

2. What can the word “appealing” in Paragraph 5 be replaced by?

A．Frightening.	B．Harmful.
C．Dangerous.	D．Attractive.

3. Which are the most effective among hundreds of carotenoids?

A．Tomatoes and red peppers.	B．Squash and spinach.
C．Lycopene and beta-carotene.	D．Polyphenols and beta-carotene.

4. What is the purpose of the article?

A．To tell people a new discovery.	B．To advise people to eat more fruit and vegetables.
C．To introduce a way to protect skin.	D．To list the functions of carotenoids to skin.

【推荐1】If you live in Washington, D. C., or Redwood, Calif., you may have noticed a small, boxy robot rolling along a local sidewalk, minding its own business, but attracting the attention of many a curious onlooker.

The robots, which look like electric rice cookers with wheels, were part of a pilot program last year by Starship Technologies focused on delivering（运送）meals from local restaurants in dozens of cities around the world.

This week, the company showed plans to broaden its delivery service beyond food to include packages, a move that made it “the world’s first robot package delivery service”. The package delivery service can only be applied in some cities in the US.

The wheeled robots have a top speed of 4 mph and can detect barriers（检测路障） from as far as 30 feet away. “The robot can operate through just about anything,” says Nick Handrick, head of operations for Starship’s D. C. office, “If you have something in the way, it’s able to climb it.” By giving customers control of when deliveries occur, Starship Technologies is promoting its service as a way to combat package theft.

To sign up for the service, which costs a little more than $10 per month, customers need to download the company’s app. Customers then create a “Starship Delivery Address,” a unique address inside a Starship facility, instead of a home address, where they can have packages sent from places such as Amazon. com.

Once a package is delivered to the Starship address, customers receive a text notice that allows them to schedule a home delivery through robot. The robots are opened by customers with a mobile phone code (代码).

1. What do we know about Starship Technologies company?

A．Packages are delivered by its robots all round America.

B．Its robots have taken on package delivery for a long time.

C．It is the first to provide robot package delivery service.

D．Its delivery service is the best of all in the world.

2. What does the underlined word “combat” in Paragraph 4 probably mean?

A．propose.	B．prevent.
C．report.	D．discover.

3. What can we learn about robot package delivery service?

A．Customers can’t open the robots without a mobile phone code.

B．Starship Delivery Address is the customer’s home address.

C．Customers have to pay a little more than $10 each time.

D．Robots themselves have control over when to deliver packages.

4. What is the passage mainly about?

A．Robot delivery service is taking off.

B．Humans are being replaced by robots.

C．Everything can be done by robots.

D．Packages can be delivered by robots.

【推荐2】It’s common knowledge that some countries have higher life expectancies (预期寿命) than others, but the city you live in can also affect your health.

Some cities are hard on their residents. In places with poor city planning, for example Lagos, which was called out recently by the Economist Intelligence Unit, public spaces are few, making outdoor activities hard. Lack of infrastructure (基础建设) blocks the streets with cars and the air with pollutants, and residents work long hours for little money.

These are just some of the factors concluded by Spotahome, a rental agency. They’ve analyzed data from a range of sources, including the World Health Organization, TripAdvisor and the CIA World Facebook to score each city on health, gym availability and quality, life expectancy, obesity (肥胖), green space and other elements to make a list to work out a list of the world’s healthiest cities.

The list is certainly Euro-centric but continuous sunshine is seen as a positive thing, even if it may be more of a disadvantage in other regions. But it does go some way towards suggesting which cities are getting it right in providing a good life for their residents. It may not be surprising to learn that most of the healthiest cities are in northern Europe, known for its people-first approach to city planning. The cities of Australia and Canada also do well — but Alaska, the first U.S. city is only in 34th place. The U.K. doesn’t fare too well either — its only city in the top 50 list is London, in 40th.

Whether you’re planning a wholesome holiday, or simply wondering what your city can do better, this list of the 50 healthiest cities will give you pause for thought about the future of city planning. Here are the attractive, healthy-eating, clean-aired cities that are getting it right.

1. What plays the key role in building a healthy city according to the text?

A．City planning.

【推荐3】“While animals can’t pick out precise numbers, they can understand that more is more. Interestingly, we know now that numerical（数值的）competence is present on almost every branch of the animal tree of life,” says Andreas Nieder, a neurobiologist from the University of Tuebingen. “Different groups of animals obviously developed this trait（特点）independently from others and that strongly indicates that it has to be of adaptive value.”

Honeybees, for instance, can remember the number of landmarks they pass when searching for food in order to find their way back to the hive. The last common ancestor between honeybees and primates lived about 600 million years ago. But still, they evolved numerical competence that, in many respects, is comparable to vertebrate（脊椎动物的）numerical competence. Also, for example, male frogs sing “advertisement” calls to attract females. The females, listening for the complexity of their calls, choose the male that sings the most calls.

Wolves are more likely to hunt successfully if they have the right number of wolves in their pack for the size of their prey（猎物）: With prey like deer, only around six to eight wolves are needed, while hunting wild ox requires a pack of nine to thirteen. Their prey also uses this concept to protect themselves from predators — deer tend to live in large herds to reduce the chance of any individual becoming prey. So obviously they are assessing the number of individuals in their groups for their everyday life situations.

Despite these many examples of numerical competence in animals, this subject has not gotten many first-hand studies. “Many of these behavioral findings in the wild have usually been collected as by-products or accidental findings of other research questions,” says Nieder. He argues that more research needs to be done to fully understand the numerical competence.

1. The phenomenon of animals having their own numerical competence shows that       .

A．all groups of animals are related in some ways

B．numerical competence must have a survival benefit

C．the intelligence of animals varies with different environments

D．animals’ numerical competence is determined by their adaptability

2. What role does numerical competence play in wolves’ hunting?

A．It helps them form hunting groups.

B．It gives them more options to hunt.

C．It makes them discover more prey.

D．It offers them new skills to hunt.

3. How does the author mainly develop this text?

A．By listing figures.	B．By asking questions.

4. From which is the text probably taken?

A．A biology textbook.	B．A health magazine.

【推荐1】Around the world there are some festivals that for some of us may sound bizarre.

In England they celebrate the rolling cheese race, which occurs every year on the last Monday in May. This festival’s characteristic is a contest where an official rolls cheese down a steep hill and festival-goers go chasing after it. The winner is the first one to reach and catch the cheese.

Another festival celebrated in England is the world championship of grimaces ( 鬼脸 ) . It is a celebration that dates back to 1297 and is celebrated during the month of September. The task is to perform the best grimace using anything you can to win.

The worldwide championship of wife lifting is celebrated in Finland. The game is based on Viking traditions where a man should carry away his neighbour’s wife. According to the rules, any woman above 17 is considered as a wife, so if you are within this age, take care while visiting this country during the month of July.

Many of you have watched Pirates of the Caribbean and have known something about pirates. The 19th of September has been declared worldwide as the day to talk like a pirate. Plenty of people have celebrated it thanks to the publicity ( 宣传 ) on the Internet.

First staged in 1998, the Boryeong Mud Festival is an attraction that pulls more than a million visitors to the South Korean city. As you all know, the town is said to be rich in minerals, so there is no shortage of mud. Mud is trucked onto Daecheon Beach for tourists and locals to enjoy the festival to their best.

The Monkey Buffet Festival is held in Thailand to develop tourism. It’s an annual feast held for about 600 monkeys. The Monkey Buffet Festival is held in honour of the Hindu gods Ram and Hanuman and involves 3, 000 kilograms of vegetables and fruit being laid out for monkeys to stuff themselves.

【推荐2】I was about 30 years old and was working as a firefighter in the South Bronx’s Engine Co. 82. It was a restful Sunday and between alarms I rushed to the office to read a copy of the the New York Times. I read an article on the Book Review section which openly stated what I took to be a calumny—that William Butler Yeats had gone beyond his Irishness and was forever to be known as a universal poet. As I read it, my blood began to boil.

I grabbed a piece of paper and wrote out a letter of anger to the editor. Yeats had lived his life and written his poetry through the very essence of his Irish sensibility. It was offensive to think Irishness was something to be transcended. I don’t know why I felt it my duty to safeguard the reputation of the world’s greatest poet. I just knew that I had to write that letter.

After my letter got published, I received a letter from The New Yorker, asking for an interview. When my article Fireman Smith appeared in that magazine, the editor of a large publishing firm called me, asking if I was interested in writing a book about my life. I had little confidence to write a whole book, though the subject was worthy. I wrote Report From Engine Co. 82 in six months, and it sold really well. In the years that followed, I wrote three more best—sellers.

Being a writer had been far from my expectations. How had it happened? I often found myself thinking about it, and my thoughts always came back to that letter to the New York Times. For me, the writing was a natural consequence of the passion I felt and the subjects represented the great values burning within me as I wrote.

Your education and your experience will guide you toward making a right decision, but your passion will enable you to make a difference in whatever you do. That’s what I learned the day I stood up for Ireland’s greatest poet.

1. What does the underlined sentence in paragraph one imply?

A．I felt awkward when I read the article.	B．I felt angry at the statement in the article.
C．I became excited when I read about Yeats.	D．I was very proud of Yeats being a universal author.

2. According to the author, what is the key to his success in writing?

A．His skills in arguing.	B．His educational background.
C．His passion for writing.	D．His experience as a firefighter.

3. What’s the best title of the passage?

A．My Journey to Be a Writer.	B．A Letter that Changed My Life.

【推荐3】You are on your way to a concert.At a crossroad,you see a group of people, all staring at the sky.Without even thinking about it, you stare upward, too. Why? In the middle of the concert,someone begins to clap and suddenly the whole room joins in.You do,too.Why?

Social proof determines that people feel they are behaving correctly when they act the same as other people. In other words, the more people who follow a certain idea, the better or truer we consider the idea to be. An experiment carried out by the psychologist(心理学家）Solomon Asch shows how peer pressure can influence common sense.A subject is showed a line,and next to it three lines - one shorter, one longer and one of the same length as the original one. He must show which of the three lines similar to the original one. If the person is alone, he gives a correct answer. Now, five unknown actors enter the room.One after another, they give wrong answers. And in one third of cases, the subject will answer incorrectly to match the other people's responses.

Why do we act like this? Well, in the past, following others was a survival method. Suppose that one day 5,000 years ago, you were travelling with your hunter friends. Suddenly,they all ran away.What would you have done? Would you have stood still, weighing up whether what you were looking at was a lion or something that just looked like a lion? No,you would have run, too.We are generations of those who copied others' behaviors. This is so deeply rooted in us that we still use it, though it offers few survival advantages today.

Social proof is the evil behind many things. The advertising industry, for example, often makes use of it.Therefore, be doubtful whenever a company says its product is "the most popular". Remember British novelist W.Somerset Maugham's words, "If 50 million people say something foolish,it is still foolish."So should we always follow the crowd?
