Passage Three
All whales fall into two groups, those with teeth and those without. Both beluga and dolphin belong to the suborder of toothed whales known as Odontoceti, along with porpoises, narwhals, pilot whales, killer whales and the largest toothed creature in the world, the sperm whale. Size differences among the Odontoceti are remarkable. A common porpoise will run only 4 or 5 feet in length and 300 pounds in weight; a sperm whale may be 10 times as long and 300 times as heavy. The beluga falls in between, weighing up to 2,000 pounds. And it does chirp. In fact, it makes a great variety of squeaking, whistling, and clicking sounds, which have earned it the name of sea canary.
The toothless, or baleen, whales belong to the suborder of Mysticeti. This is a group of generally large whales, formerly abundant in all the oceans of the world. Though reduced by hunting, most species are still found along the coasts of the United Stated and Canada. All but two
A. a bird
B. a giant
C. an elephant
D. a submarine

Passage Five
Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
Eleven gray whales have died in the San Francisco Bay in the last three weeks. No one knows why the whales are dying.
Last year 270 whales died along the whales’ migration route. Many people think starvation is the cause. This year the dead whales seem to have more blubber (fat) on them.
Twenty years ago, the gray whale was listed as an endangered species.
Some scientists think that the larger number of whales makes it hard to find enough food. More whales create more pressure on the food supply, a supply that some scientists say may have dwindled as a result of the warm waters of E1 Nino.
Most of the whales have been dead for many days before they are found and studied. This makes it hard to find the reason for death.
65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year
A. the whales travel such a long distance
B. there are more whales than there used to be
C. the whale bodies are too old to study by the time they are found
D. the whales are endangered
Passage Three
We all associate colors with feeling and attitudes. In politics dark blue often means "tradition", and red means "social change". But blue can also mean sadness (I’m feeling blue), white is often for purity, although in China white is worn at weddings and black for funerals. Advertisers are aware of the importance of selecting colors according to the way people react to them. Soap powders come in white and light blue packets (clean and cold, like ice); cereals often come in brown packets (like wheat fields), but cosmetics never come in brown jars (dirty).
Where do these ideas come from Max Luscher from the University of Geneva believes that in the beginning life was dictated by two factors beyond our control: night and day. Night brought passivity, and a general slowing down of metabolism; day brought with it the possibility of action, and increase in the metabolic rate, thus providing us with energy and initiative. D
A. resemble ice
B. show quality
C. suggest purity
D. attract customers
