Shorts may feel nice and casual on your legs ...

Shorts may feel nice and casual on your legs on a warm summer’s day, but they’re not so gentle on your wallet.  1. Usually the fact that one obviously uses less cloth than the other makes it hard to be accepted So what gives?

It turns out clothing sellers aren’t trying to cheat you by charging you too much money. They’re just pricing shorts according to what it costs to produce them. 2. Extra material does go into a full pair of pants but not as much as you may think. As experts explain, shorts that don’t fall past your knees may contain just a fifth less cloth than ankle-length trousers. 3.

Those same details that end up accounting for most of the material—pockets, belt loops, waist bands—also require the most human labor to make.4.The physical cotton in blue jeans accounts for just a small part of its price Jag. Most of that money goes to pay the people stitching (缝合) it together, and they put in roughly the same amount of time whether they’re working on a pair of pants or some shorts.

5. For another example, short-sleeved shirts cost roughly the same as long-sleeved shirts. There are also numerous invisible factors that make some shorts more expensive than nearly identical pairs, like where they were made9marketing costs, and the brand on the label. If you don’t want to spend $40 on something that covers just a small piece of leg, stay at home with your wallet!

A. More or less, shorts almost cost what pants do.

B. This is where the true cost of a garment is determined.

C. This price trend becomes popular across the fashion field.

D. This is because most of the cloth is sewn into the top half.

E. In general, a pair of shorts isn’t any cheaper than a pair of pants.

F. To tell you the truth, it is a real bargain to pay for a pair of shorts.

I am traveling home. It is bitterly cold and snowy, but the warm train is right on time. I feel pleasantly satisfied as I look out at the rush hour traffic on the motorway. I feel more satisfied as the smell of fresh coffee announces the arrival of the drinks service. Swiss friends often tell me, proudly, that their rail service is the best in the world, but recently, one experience has proved that the great Swiss love affair with their railway has turned a little sour.

It all began with the decision to end ticket sales on trains. One cold morning I arrived at my local station only to find that the ticket machine was broken. No matter, I thought, I have got a smart phone, and I hurriedly set about buying my ticket that way. This was not as easy as I had expected, busying myself between credit card and phone with freezing cold fingers, but, by the time I got on the train to Geneva I had an e-ticket and I proudly showed it to the conductor. Unfortunately she told me that my ticket was not valid. Several weeks later a letter arrived from Swiss railways together with a fine for 190 francs ($ 210).

The good people there tell me the formal payment for my ticket from my credit card company arrived four minutes after my train left the station. That means, they say, that I bought my ticket on the train—and that is strictly prohibited.

Swiss railways say their policy is designed to protect honest ticket-paying passengers, but a quick look at their balance sheet suggests something else. The company is making about $2 million a month from fines.

Although train travel is still popular, those seats do not feel as comfortable; the coffee does not smell quite so good—because Swiss railways have lost, for now anyway, something far more precious than $2 million a month: good relations with their customers.

1.What can we learn from paragraph 1?

A. The Swiss trains usually come late.

B. Traffic on the motorway goes smoothly.

C. The author hates traveling on the Swiss train.

D. The author is generally pleased with the Swiss rail service.

2.Why did the conductor say that the author’s e-ticket was invalid?

A. It was purchased online.

B. It was paid for after the train’s departure.

C. It was purchased on a ticket machine.

D. It was paid on a smart phone.

3.What does the author want to show by telling the experience?

A. The fine was unfair.

B. The conductor was impolite.

C. E-tickets are getting popular.

D. Credit cards can be inconvenient.

4.What does the author think of the new policy of Swiss railways?

A. It attracts more people to travel by train.

B. It makes the company lose a lot of money.

C. It damages company-customer relations.

D. It protects honest ticket-paying passengers.

Your circle of friends may help you get a better reading on your overall health and wellness rather than just using wearable devices such as a Fitbit, according to researchers.

The study, published in the journal PLOS ONE, analyzed what the structure of social networks says about the state of health, happiness and stress.

"We were interested in the topololgy (拓扑学) of the social network — what does my position within my social network predict about my health and well-being said Nitesh V. Chawla, a professor at the University of Notre Dame in the US.

“What we found was the social network structure provides a significant improvement in predictability of wellness states of an individual over just using the data obtained from wearables, like the number of steps or heart rate,” Chawla said.

For the study, participants wore a Fitbit to capture health behavior data about walking, sleeping, heart rate and overall activity level. They also completed surveys and self-assessments of their stress, happiness and positivity.

Cbawla and his team then analyzed the data with a machine learning model, alongside the connections and characteristics of an individual's social network.

The study showed a strong correlation (相关性) between social network structures, heart rate, number of steps and level of activity.

Social network structure provided significant improvement in predicting one's health and well-being compared to just looking at health behavior data from the Fitbit alone.

For example, when social network structure is combined with the data from wearables, the machine learning model achieved a 65 percent improvement in predicting happiness.

The model also achieved a 54 percent improvement in predicting one's self-assessed health prediction, a 55 percent improvement in predicting positive attitude and a 38 percent improvement in predicting success.

This study asserts (断言) that without social network information, we only have an incomplete view of an individual's wellness state, and to be fully predictive or to be able to obtain interventions (干扰). It is critical to be aware of the social network, Chawla said.

1.What did the study find?

A.How people choose their friend circles.

B.What factors decide your friend circles.

C.How your circle of friends influences you

D.What your circle of friends says about your health.

2.How did the researchers draw their conclusions?

A.By comparing data. B.By giving examples.

C.By analyzing cause and effect D.By describing personal experiences.

3.What does the underlined word “critical” mean in the last paragraph?

A.Easy. B.Common.

C.Important. D.Challenging.

4.What do Chawla's words in the last paragraph tell us?

A.How fitness devices can connect your circle of friends

B.That a person's social network is part of his health picture.

C.The best ways to make friends and keep a healthy social circle

D.That wearable devices are not useful for understanding someone's health.

Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason is that crossing one leg over the other increases resistance, making it even harder for the blood to circulate and increase your blood pressure. Thus, you shouldn’t have your legs crossed for more than 15 minutes, and it’s important that you get up and walk around at least once every hour.

Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat on the floor. When you sit with your legs crossed your hips are in a twisted position, which can cause pressure on your lower and middle back and neck.

You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful. This is because when one leg sits on top of the other, it causes pressure on the veins and nerves in your legs and feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

1.A study published in Blood Pressure Monitoring showed that 　　　　　　 .

A. crossing your legs can raise your blood pressure

B. crossing one leg over the other can increase the blood circulation

C. you should have your legs crossed once every hour

D. you should get up and walk around for more than 15 minutes

2.Crossing your legs can cause some health problems except 　　　　　　 .

A. pressure on veins and nerves in legs and feet

B. permanent nerve damage

C. unstable posture

D. neck and back pain

3.What seems to be the writer’s attitude toward crossing legs?

A. Supportive.　　 B. Negative.

C. Casual.　　 D. Confused.

Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. You won’t feel any immediate effects, but sitting for long periods of time will hurt you forever.

Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it’s not easy to maintain perfect posture all day at the office. When you sit with your legs crossed your hips are in a twisted position, which can cause one of your pelvic bones(骨盆) to rotate. Since your pelvic bone supports your neck and spine（脊椎）, this can cause pressure on your lower and middle back and neck.

You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful or have the feeling of being asleep. This is because when one leg sits on top of the other it causes pressure on the veins（静脉） and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

1.Which of the following is not the consequence of crossing legs?

A. Neck and back get hurt.

B. Feet and legs become numb.

C. Blood pressure goes up.

D. Pelvic bones keep perfect postures.

2.What does the underlined word “rotate” in Para3 mean?

A. break seriously

B. hurt greatly

C. move casually

D. straighten suddenly

3.What does the text mainly talk about?

A. How to choose a proper sitting posture

B. It is advisable not to sit with legs crossed

C. How to develop beneficial habits

D. Blood pressure harms our bodies.

Your four-legged friends may soon have their own channel. DogTV, cable TV’s first channel for dogs, is mostly about keeping lonely dogs calm.

There are about 78 million canines(犬) in the United States. DogTV is aimed at the many of these that are left alone for long periods. Dogs are social animals and often grow anxious when left on their own. They may bark, chew shoes, and generally get into trouble. DogTV, which was launched last February, is designed to help ease their boredom and anxiety.

Creators of the cable service approached their task scientifically. The sounds, colors, and camera angles have all been adjusted for canine senses. For instance, colors are made more vivid so that dogs can see objects clearly. DogTV does not, as you might think, show Scooby-Doo and Clifford the Big Red Dog. Rather, there are three types of DogTV “shows.” The first aims to relax dogs. These segments show dogs resting to the sound of calming music. The second kind shows pleasant (for a dog) day-to-day settings, like riding in a car or walking down a street. The third type is meant to stimulate ---like a scene of two dogs playing in a field. “Dogs love watching other dogs being active on the screen,” says Beke Lubeach, a DogTV spokesperson. She says that birds, monkeys, and zebras also make dogs take notice.

Not everyone is buying it. “I think a lot of this is to make us feel better as opposed to making the pet happier,” says Dr. Ann. E. Hohenhaus of New York’s Animal Medical Center. She tells The New York Times, “Your pet needs adequate exercise and an interesting environment.” You cannot just turn on the TV and hope your dog is going to　 get better.

On the other hand, the Humane Society animal shelter in Escondido, California, tried out DogTV at its shelter. Sally Costello, the director, says workers observed that dogs exposed to the channel were calmer and barked less.

DogTV has been seen only in Southern California so far. But it is scheduled to go national soon. Owners of the commercial-free channel hope to charge about $5 a month for their service.

1.The following programs are often broadcast on DogTV EXCEPT________.

A. Dogs resting to the sound of calming music.

B. Programs like Cliff ford the Big Red Dog.

C. A scene of two dogs playing in a field

D. Dogs riding in a car or walking down a street

2. What does Dr. Ann E. Hohenhaus agree according to the fourth paragraph?

A. Everyone who owns dogs will buy the service.

B. DogTV can make your dogs happier and happier.

C. Dogs need more than a good animal channel.

D. DogTV makes people happier than pet dogs.

3.Which of the following is RIGHT according to the passage?

A. DogTV will only be seen in Southern California.

B. There will be many ads on the animal Channel.

C. Dog owners will enjoy the programs very much.

D. Dogs exposed to the channel will become calmer.

4.Which of the following can serve as the best title for this passage?

A. How to Make Your Dog Happier.

B. A New TV for Dogs

C. How to Keep Dogs Calm.

D. A New Channel to Calm Dogs Down
