Imagine that you are in school, giving a speech to your class. Now think what it feels like when stammering (口吃) makes it a struggle to communicate your thoughts and feelings to other people.
The King’s Speech, which won the best picture at the Academy Awards in March, 2011, focuses on stammering along with other speech-related problems. The movie tells the story of Britain’s King George VI, who became king after his brother Edward VIII gave up the crown to marry an American woman.
As a result of British actor Colin Firth’s performance, people are starting to realize that stammering can damage a person’s self-confidence and cause him or her to escape from life.
“The serious problem is unseen and unheard,” said Norbert Lieckfeldt, an expert at the British Stammering Association, in an interview with a news reporter.
“Stammering masks your ability,” he said. “It's a serious disability.”
Most stammerers face bullying (欺负) in school, something that is “usually carried over into the workplace”.
George VI’s stammer took away his confidence as a speaker. But Samantha Mesango, a speech coach based in the UK, believes that speech problems are more common than most people realize. “Some simply don’t like the sound of their own voice; others are scared of speaking in public,” she said.
Travis Treats from St．Louis University praised The King’s Speech. He said it shows that “how one’s speech does not mean what one is inside”. He also added that people who stammer need to be heard and our society should recognize that they have a lot to give to the world.

Many people believe the glare from snow causes snowblindness. Yet, 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. A man's eyes frequently find nothing to focus on in a broad expanse of barren snow-covered terrain(地域). So his long look continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and eyeballs become sore and the eye muscles ache. Nature offers this discomfort by producing more and more liquid which covers the eyeball. The liquid covers the eyeball in increasing quantity until vision became not clear, and then is not easily seen and the result is total, even though not very long, snowblindness.
Experiments led the Army to a simple method of solving this problem. Scouts, ahead of a main body of 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 too can focus. The men following can then see something. Their eyes focus on a bush and have something to see. 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 solid white terrain is solved.

A. need for dark glasses      
B the whiteness from snow
C. headaches, watering eyes and snowblindness 
D. snow glare and snowblindness
2. According to the author, recent work on snowblindness shows that it is caused by ________.

D. focusing on dark colored objects for a very long time
3. Suppose you walk across a completely snow-covered area, what should you do to solve the problem of snowblindness?
A. By wearing dark sun glasses.
B. By throwing an extra pair of black shoes ahead.
C. By asking the Army for help.
D. By walking backwards.
4. A suitable title for this passage would be ________.
A. Snowblindness and How to avoid it     B. Soldiers in Snow　　
C. Nature's Cure for Snowblindness       D. Snow Vision
