Some people are lucky enough to be born with a good sense of direction and even if they have just visited a place once, they will be able to find it again years later.
I am one of those unfortunate people who have a very poor sense of direction and I may have visited a place time after time but I still manage to get lost on my way there.
When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hoped that by some chance I would get to the spot I was heading for.
I am no longer too shy to ask people for directions, but I often receive replies that puzzle me. Often people do not like to admit that they do not know their hometown and will insist on telling you the way even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you cannot possibly hope to remember; and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite direction to that in which you should be going.
If anyone ever asks me the way somewhere，I always tell him/her that I am a stranger to the town in order to avoid giving him/her wrong directions, but even this can have embarrassing results.
Once I was on my way to work when I was stopped by a man who asked me if I would direct him to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building.
However, at this point, I decided it was too late to turn back and search him out of the crowd behind me, as I was going to meet with someone at the office and I did not want to keep him waiting.
Imagine my embarrassment when my secretary showed in the very man who had asked for directions to my office and his astonishment when he recognized me as the person he had asked.

Bamboo is one of the nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains(平原).
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables(绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.
In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills(钻) can help to make the poor thirsty fields to be watered.

Your smartphone(智能手机) can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little device（设备）of yours – it might also spread disease.
“People are just as likely to get sick from their phones as from handles of the bathroom,” Jeffrey Cain, the president of the American Academy of Family Physicians, told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms(大肠菌), a kind of bacteria found in excrement(粪便)，with about 2,700 to 4,200 units of the bacteria on each phone. In drinking water, the healthy limit is less than 1 unit per 100 ml of water. This bacteria can cause flu, pinkeye（红眼病）and diarrhea(腹泻).
Although computers, keys and pens all carry germs(细菌), our smartphones get far dirtier. They touch a lot of stuff, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds of Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said.
What’s even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease（油脂）, an environment that germs really like.
Compared to traditional keypads（键盘）, touch screens transmit（传播）germs more easily to hands. According to Time magazine’s website, an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.
So how do you keep your smartphone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.
The underlined word “dark” in the first paragraph means .

A．black	B．hopeless
C．unclear	D．unpleasant

By saying “Some things we think are personal are actually more public than we imagine”, Cain meant that .

A．people love to share their smartphones more than they realize

B．our personal items could be as risky to our health as public items

C．smartphones are used in public places more than people realize

D．most people don’t know how dirty their cell phones are

Compared with traditional keypads, smartphones .

A．make contact with our hands more often

B．are greasier and need more alcohol to clean

C．get warm more easily and are harder to clean

D．get much nearer to our faces

What is the article mainly about?

A．Tips on the use of smartphones.

B．Health problems caused by the use of smartphones.

C．The danger of coliforms infection.

D．The influence that smartphones have on our life.

Just five minutes of exercise a day outdoors can improve mental health, according to a study.
Researchers from the University of Essex, UK have found that as little as five minutes of a “green activity” such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem (自信).
Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show.
Barton and Pretty looked at data from 1,252 people of different ages, genders (性别) and mental health status (情况) taken from 10 studies in Britain.
They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail (路径).
They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent.
Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill.
Green and blue
A bigger effect was seen with exercise in an area that also contained water – such as a lake or river.
“This is because historically we are drawn to water to survive and it is in our genetic (遗传的) make-up to be at one with nature,” the researchers wrote in their report.
Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from “green exercise”.
“Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health.”
He also said exercise programs outdoors could benefit youth offenders.
How is the study this article refers to different from other studies?

A．It determined the exact amount of time needed.

B．It took longer to finish the research.

C．It involved more people.

D．It was led by just two researchers.

What can we conclude from the findings of the study?

A．Gardeners and farmers do not need “green exercise”.

B．Just five minutes of “green exercise” daily can help improve mental health.

C．Walking in a park with a lake will weaken the effect.

D．“Green exercise” is not suitable for the mentally ill.

According to Pretty, _______ would probably benefit the most from “green exercise”.

A．stressed, inactive people

B．office worker

C．youth offenders

D．women and children
