When a storm is coming, most people leave the area as quickly as possible and head for safety…But there are a few people who will get into their cars and go straight for the center of the storm．These people are willing to risk being killed by floods or 100-Kilometer- an-hour winds for the excitement of watching the storm close up．

　 “Storm chasing (追逐)”is becoming an increasingly popular hobby，especially in the Midwest of the United States, where there are frequent storms between March and July．A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to l,000 kilometers to where the storm will be and waits for it to develop．

　  Although anyone can do it，storm chasing is extremely dangerous．The power of a big storm  can throw a cow into the air or destroy a whole house in seconds．Storm chasers are also often hurt in accidents caused by driving in a heavy rain．If you are a beginner, it is much safer to join a group for storm - chasing vacations during the storm season．

　  Even then，storm chasing is not all adventure and excitement．“Storm chasing is 95％driving，”says Daniel Lynch，who spends most of his summer storm-chasing．“Sometimes you

Can sit around for hours waiting for something to happen，and all you get is blue sky and a few light showers.”

　  However，for storm chasers，it is all worth it. “When you get close to a storm，it is the most exciting sight you will ever see in your life，”says Jasper Morley．“Every storm is an example of the power of nature．It is the greatest show on Earth．”

　Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness ,when exposed to several hours of“ snow light”.

　　The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow -covered country. Rather ,a man’s eyes frequently find nothing to focus on （聚集） in a broad space of snow- covered without- grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid （流 体） which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.

　　Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow - covered landscape. Even the scouts themselves throw lightweight, dark - colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow -blanketed landscape. By focusing their attention on one object at a time. the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.

To prevent snowblindness caused by the strong light from snow, wearing glasses or not ________.

　　A. depends on whether the snow is white enough

　　B. makes no difference

　　C. makes much difference

　　D. depends on whether the snow is thick

When the eyes are tired, tears flow out ________.

　　A. to clear the vision

　　B. to make the eyes stop searching

　　C. to make the vision unclear

　　D. to produce more and more liquid

Snowblindness can be avoided ________.

　　A. by moving one’s gaze back and forth

　　B. by walking ahead and keeping looking around

　　C. by making up for the discomfort of one’s eyes

　　D. by providing the eyes with something to focus on

What is eco­fashion？Eco-fashion is about making clothes that take into account the environment, the health of consumers and the working conditions of people in the fashion industry.  It is a complex phenomenon and the common use of the term covers two aspects of fashion —‘ecological’ and ‘ethical’．Ecological fashion usually refers to textile (织物) and clothing production processes and the environmental issues surrounding them；ethical fashion generally relates to the working conditions involved in the producing processes.

What are the problems with fashion？A closer look at the fashion industry points out many problems that are common practices in the creation of our fashions from the field to the factory. Firstly，the production of textiles pollutes the environment heavily. Cotton­planting uses pesticides；sheep­farming and wool­cleaning contribute to global warming；synthetics­making (人造纤维生产) brings about waste which does harm to our environment. Secondly，every stage of clothing production has a significant effect on the environment. They all use a great deal of energy，and some also involve harmful chemicals. In addition to this，there is a lot of waste produced in the process，especially in the form of polluted water. Thirdly，growing consumption levels and our shopping habits further worsen the bad effects. We are now buying clothes in increasing quantities without realizing the scale on which it affects natural environment，and we are also quick to throw away clothes that have been worn only a couple of times.

Then，how to solve the problems? Other industries that design products are ahead of the fashion industry when it comes to choosing sustainable materials, designing for minimum waste, choosing energy efficient manufacturing and creating products for longevity. The fashion industry has been slow to adopt these changes and part of the problem is the very nature of fashion. To a large degree，it is the fashion producers that really have the power and the responsibility to shape our future. There are numerous ways in which these producers can reduce their ecological footprint，from switching to green energy and reducing energy use，through selecting sustainable materials and choosing local suppliers，to recycle and minimize waste. On the other hand，as consumers we can all make contributions by selecting environmentally friendly clothing and reducing clothing consumption.

There is some concern that eco friendly fashions are just a trend that we will eventually grow tired of but we can make sure that doesn't happen. Now many people are beginning to shop for organic food products because the benefits of eating food free of chemicals are straightforward and immediate. They relate directly to our personal health. In fact, choosing eco­fashion can also contribute to our personal health, though it is mostly done by way of keeping the health of the planet.
