Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

The human criterion for perfect vision is 20/20 for reading the standard lines on a Snellen eye chart without a hitch. The score is determined by how well you read lines of letters of different sizes from 20 feet away. But being able to read the bottom line on the eye chart does not approximate perfection as far as other species are concerned. Most birds would consider us very visually handicapped. The hawk, for instance, has such sharp eyes that it can spot a dime on the sidewalk while perched on top of the Empire State Building.

It can make fine visual distinctions because it is blessed with one million cones per square millimeter in its retina. And in water, humans are farsighted, while the kingfisher, swooping down to spear fish, can see well in both the air and water because it is endowed with two foveae - areas of the eye, consisting mostly of cones, that provide visual distinctions. One fovea permits the bird, while in the air, to scan the water below with one eye at a time. This is called monocular vision. Once it hits the water, the other fovea joins in, allowing the kingfisher to focus both eyes, like binoculars, on its prey at the same time.

A frog’s vision is distinguished by its ability to perceive things as a constant motion picture. Known as “bug detectors”, a highly developed set of cells in a frog’s eyes responds mainly to moving objects. So, it is said that a frog sitting in a field of dead bugs wouldn’t see them as food and would starve. The bee has a “compound” eye, which is used for navigation. It has 15,000 facets that divide what it sees into a pattern of dots, or mosaic. With this kind of vision, the bee sees the sun only as a single dot, a constant point of reference. Thus, the eye is a superb navigational instrument that constantly measures the angle of its line of flight in relation to the sun. A bee’s eye also gauges flight speed. And if that is not enough to leave our 20/20 “perfect vision” paling into insignificance, the bee is capable of seeing something we can’t - ultraviolet light.

Thus, what humans consider to be “perfect vision” is in fact rather limited when we look at other species. However, there is still much to be said for the human eye. Of all the mammals, only humans and some primates can enjoy the pleasures of color vision.

According to the passage, why might birds and animals consider humans very visually handicapped?

A. Hunman can’t see very well in either air or water

B. Human eyes are not as well suited to our needs

C. The main outstanding feature of human eyes is color vision

D. Human eyes can’t do what their eyes can do

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Television and Kids

Television is very popular and even has some benefits for kids. It helps very young children learn the letters of the alphabet, and helps other kids learn about science, cultures, and world events.

However, researchers show that too much TV is bad for children. For one thing, there is a link between watching more than four hours of TV a day and being overweight. For another thing, many TV shows are violent and upsetting. Watching these shows may cause kids to be more fearful. And of course, more time in front of the TV means less time to study. Too much TV may also be the cause of lower grades. Experts do not agree on the solution to these problems. Some say that kids should watch only educational programs; others say kids should watch no TV at all. And others suggest teaching them to watch TV as occasional entertainment, not as an everyday hobby.

Question28. What is the passage mainly about?

 

A. Benefits of kids' TV shows C. Why kids love TV    

B. Effects of television on kids D. Why kids shouldn't watch TV  

Question 29. According to the passage, watching a lot of TV may ___________________.

 

A. cause weight problems in children C. cause children to get better grades    

B. cause children to be more famous D. cause students to study more
