　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.

　　A. depends on whether the snow is white enough

When the eyes are tired, tears flow out ________.

　　A. to clear the vision

Snowblindness can be avoided ________.

　　A. by moving one’s gaze back and forth

　　B. by walking ahead and keeping looking around

　　The World Trade Organization（WTO）, established on January 1, 1995, is an open, non-discriminatory trading system. As a successor to the GATT, established in the wake of the Second World War, it is to help world's trade flow freely, fairly and predictably.

　　While the WTO is still young, the multilateral（多边的）trading system that was originally set up under GATT is already 50 years old. The system celebrated its golden jubilee（50周年纪念）in Geneva on 19 May, 1998, with many heads of states and government leaders attending.

　　The past 50 years have seen an exceptional（罕见的）growth in the world trade. Merchandise exports grew on average by 6％ annually（每年地）. Total trade in the WTO has helped to create a strong and prosperous trading system contributing to unprecedented growth.

　　China was an original member of GATT, but for historical and political reasons it was withdrawn from GATT by the government in Taibei in 1950. But over the last several years, China hopes to be seeking to resume（恢复）its contracting party status. China has become a member of the WTO before the body starts a new round of negotiations（谈判）late this year. Premier Zhu Rongji paid a nineday US visit from April 6, 1999. He is the first Chinese Premier to visit US. President Clinton agreed to have talks on China's entry into the WTO with a new round of negotiations in Beijing.

　　Now China has joined the WTO. China's entry into the WTO is not only of economical but also of political importance. China has made attracting progress since its reform and opening up to the outside world. It is growing more and more powerful in economy. China cannot be without the world just as the world cannot be without China. The entry of China into WTO will further strengthen the comprehensive national power of China; it can also quicken the economic development of the world.

GATT was founded in ______.

At a primary school Manning， Carolina， second-grade teacher David Chadwell believed that segregating(隔离) elementary-age boys and girls produces immediate academic improvement—in both genders. “Although this is a tendency， we can teach boys and girls based on what we now know.”

“They see differently. Literally，” he begins. Male and female eyes are not organized in the same way， he explains. The composition of the male eye makes it attuned(协调) to motion and direction. “Boys interpret the world as objects moving through space，” he says. “The teacher should move around the room constantly and be that object.”

The male eye is also drawn to cooler colors like silver， blue， black， grey， and brown. It’s no accident boys tend to create pictures of moving objects like spaceships， cars， and trucks in dark colors instead of drawing the happy colorful family， like girls in their class.

The female eye， on the other hand， is drawn to textures and colors. It’s also oriented toward warmer colors—reds， yellows， oranges—and visuals with more details， like faces. To engage girls， Chadwell says， the teacher doesn’t need to move as much， if at all. Girls work well in circles， facing each other. Using descriptive phrases and lots of color in overhead presentations or on the chalkboard gets their attention.

Boys and girls also hear differently. “When someone speaks in a loud tone， girls interpret it as yelling，” Chadwell says. “They think you’re mad and can shut down.” Girls have a more finely tuned aural structure； they can hear higher frequencies than boys and are more sensitive to sounds. He advises girls’ teachers to watch the tone of their voices. Boys’ teachers should sound matter of fact， even excited.

A boy’s autonomic nervous system causes them to be more alert when they’re standing， moving， and the room temperature is around 69 degrees. Stress in boys， he says， tends to increase blood flow to their brains， a process that helps them stay focused. This won’t work for girls， who are more focused seated in a warmer room around 75 degrees. Girls also respond to stress differently. When they are exposed to threat and confrontation， blood goes to their guts(内脏)， leaving them feeling nervous or anxious.

“Boys will rise to a risk and tend to overestimate their abilities，” he says. “Teachers can help them by getting them to be more realistic about results. Girls at this age shy away from risk， which is exactly why lots of girls’ programs began in the private sector. Teachers can help them learn to take risks in an atmosphere where they feel confident about doing so.”
