If you ask a person on the street to name the top predator in the sea, most people would probably say the great white shark. But they would be wrong. A great white shark is a relentless eating machine, superbly designed for its role at the top of the food chain, but the fact is, when a great white shark meets a killer whale, the killer whale has lunch. Not bad for an animal that is neither a whale nor a killer.
The killer whale, known to scientists as orcinus orca, is one of the largest, fastest, and most intelligent predators in the world's oceans. The orca is not technically a whale, but rather the largest member of the dolphin family. The name "orca" has become the preferred name for the animal, because the name "killer whale" perpetuates the myth that orcas are dangerous to humans; in fact, there has never been a recorded incident of an orca attacking a human in the wild. This is not to say, however, that orcas are not dangerous to other marine species. Orcas in the wild have been observed consuming an astonishing variety of marine species, including salmon, tuna, sharks, giant squid, penguins, sea lions, dolphins, and even other whales, which the orcas hold under water until they drown. It is thought that the English name "killer whale" came from a mistranslation of the Spanish name asesina de ballenas, or "whale killer."
Despite decades of study, many aspects of the creatures' life cycle and habits remain mysteries. Biologists only recently determined that there are, broadly speaking, three separate types of killer whale: residents, transients, and off shores. The residents live in large pods of up to 40 animals and primarily eat fish; these axe the most social of the killer whale types, with each pod having distinctive songs and complex social interactions. Transients are much quieter animals who roam large distances in groups of two to six while hunting marine mammals such as sea lions and dolphins. It is the transients who earned the orca the reputation of being whale killers. The third type of orca is the offshore variety, which rarely ventures toward coasts. These poorly understood animals travel in large groups, are somewhat smaller than their coastal cousins, and are thought to eat fish, sharks, and squid, but probably not other mammals.
The statement in the first paragraph that the killer whale is "neither a whale nor a killer" has which of the following meanings?
A.The preferred name for the orcinus orca is the orca, a name that does not have the negative connotations of "killer whale."
B.The killer whale is a type of dolphin that is not known to have ever attacked a human in the wild.
C.The orca is actually a more powerful predator than even the great white shark.
D.The killer whale is a type of dolphin that kills other whales by holding them under water until they suffocate.
E.Some believe that the name "killer whale" is an inaccurate translation of a term used by Spanish sailors that means "whale killer."

(79) It' s a day to celebrate, a time to educate, and a wa~/to make a difference. Earth Day was first observed on April 22.1970. The tradition began in the United States and is now an in-ternational focal point for people who are concerned about the environment.
Imagine a time before the Clean Air Act, the Clean Water Act, the Endangered Species Act,and even the Environmental Protection Agency. Hot topics of the time were industrial pollution,nuclear accidents, oil dependency, pesticides, and a variety of social issues. However, policy-makers were not yet acting on many important environmental problems,Earth Day grew out of grassroots action and institutional support. Student leader Denis Hayes and Wisconsin Senator Gaylord Nelson were two key organizers for the first event. Over 20 mil-lion concerned citizens rallied for clean air and water. College students were a major force in the campaign, although participants of all ages were involved. Still, we cannot really credit a handful
of individuals for the success of Earth Day. After all, a major message of Earth Day is that every single person has an important role in the environment.
(80) The first Earth Day was very successful, inspiring the passage of congressional protec-tion for air, water, and endangered species. Momentum from the demonstration also fueled theformation of the Environmental Protection Agency.
Thirty years later, the focus has changed but the urgency remains the same. Due to increas-ing amounts of scientific evidence that fossil fuels are changing the global climate, the theme for Earth Day 2000 is Clean Energy. The four major goals of Earth Day 2000 are clean cars, clean power, clean air, and clean investments.
April 22nd, 2000 is the __________years‘ anniversary of the Earth Day. 查看材料

Modem mass·production methods lower the cost of making goods,and thus give US better values.At the same time,American ingenuity(独创性)and science are constantly at work improving the quality of products.(79)In this way better quality products at good Values are continually being brought to the people of all income groups.
As an example of how this worked,when facial tissues(面巾纸)were first put on the market in 1924,they were made in limited quantities and sold 65 cents per box of 200. People like these facial tissues immediately and began asking for them when they went into different stores because there was such a demand for the product ,manufacturers began making tissues in larger and larger quantities because the manufacturers were making tissues in greater quantities,their
production costs were lowered,SO that the price of tissues went down.(80)In the meanwhile,The quality of facial tissues was constantly improving, because more manufacturers went into the business of making tissues,and each manufacturer strove to make his product better than his competitors&39;.Today,instead of costing 65cents,a box of 200 tissues costs around one-third of
that price,and they are both softer and stronger. When people are free to compete-when they are free to make more things and make them better-everyone benefits.

B.the quality of the goods should improve
C.the price and the quality should both rise
