[EX Q]: Context: Many people have problems with their vision, or ability to see. Often, the problem is due to the shape of the eyes and how they focus light. Two of the most common vision problems are nearsightedness and farsightedness, which you can read about below. You may even have one of these vision problems yourself. Usually, the problems can be corrected with contact lenses or lenses in eyeglasses. In many people, they can also be corrected with laser surgery, which reshapes the outer layer of the eye.

The Figure 1.1 shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. Q: Sometimes squinting the eyes can help someone see more clearly. Why do you think this works? A: Squinting may improve focus by slightly changing the shape of the eyes. When you squint, you tighten muscles around the eyes, putting pressure on the eyeballs. Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure 1.2). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. Q: Joey has hyperopia. When is he more likely to need his glasses: when he reads a book or when he watches TV? A: With hyperopia, Joey is farsighted. He can probably see the TV more clearly than the words in a book because the TV is farther away. Therefore, he is more likely to need his glasses when he reads than when he watches TV. 
 Question: in hyperopia, the eyeball is
[EX A]: shorter than normal.

[EX Q]: Context: It is winter in many parts of the world. For some areas, that means snow. Maybe even lots of snow. If you don't have to drive in it or remove it, snow can be very beautiful. When snow covers everything around you, the world looks like a "winter wonderland". That is the name of a very popular song about winter. Richard Smith and Felix Bernard wrote the song back in 1934. There are hundreds of recordings of this happy song. But winter is not always such a beautiful and happy time. It's cold outside. You try hard to keep warm. The days are darker and shorter. The sun rarely shines. The leaves on the trees are brown. It isn't surprising that some people are sad in winter. And some people dream about being somewhere else where it's warm and pretty--like the state of California. The Mamas and the Papas recorded this famous song "California Dreaming". During the 1960s, many other famous rock groups released songs about winter. Here is a poetic song by Simon and Garfunkel called "A Hazy Shade of Winter". They sing about life and hope and possibilities. In 1968, the group Blood, Sweat and Tears recorded this gentle, sad song about winter. They sing about a lost love and forgotten memories in "Sometimes in Winter". In the early 1990s, Tori Amos wrote and recorded the beautiful song called "Winter". She enjoyed singing about winter when she was a child. Finally, on a happier note comes this song written and recorded by Fountains of Wayne in 2003. They sing about a snowstorm in a New England town. Nothing unusual there. But instead of being sad or tense about the snow, they write a song about it. 
 Question: Which of the songs can bring us hope of life?
[EX A]:
a hazy shade of winter.
