第1题：The questions in this group are based on the content of a passage.After reading the passage, choose the best answer to each question.Answer all questions following the passage on the basis of what is stated or implied in the passage. 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 theEnglish 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.\

第4题：Read the argument and the instructions that follow it, and then make any notes that will help you plan your response. Write your response on a separate sheet of paper. If possible, type your essay on a word processor. A、spokesman for a dairy company issued the following statement: Many consumers buy organic milk because they are concerned about the consequences of the widespread use of recombinant bovine growth hormone and antibiotics in the conventional dairy industry. These concerns, however, are unfoundeD、While bovine growth hormone has been shown to produce significant developmental effects in cattle, no study has ever shown that its presence in commercial milk has had any developmental effects on human consumers. Regarding antibiotics, while it has been argued that large-scale, preemptive use of antibiotics in cattle feed can interfere with the animals’ immune systems and can lead to the proliferation of antibiotic-resistant strains of bacteria, neither of these effects affect the quality of the milk produced by cattle that are fed antibiotics. Therefore, there is no reasonable justification for a consumer to pay $5 for a gallon of organic milk when a perfectly good gallon of conventional milk can be had for half the price. Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative examples or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.
