第1题

All whales fall into two groups, those with teeth and those without. Both beluga and dolph

in 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 of the Mysticeti reach 40 feet or more at maturity, with the blue whale running up to 100 feet and tipping the scales at up to 130 tons. This whale is by far the largest creature that has ever lived on earth, 4 times the weight of the largest dinosaur, 30 times that of an elephant.

With what topic is the passage mainly concerned？

A．Breeding habits of whales.

B．Differences between whales.

C．Efforts to preserve whales.

D．The intelligence of whales.

第3题

Jupiter Communications, a market research firm, reports that 72% of teenagers in the U

nited States will be online by 2003 (Stanton, 2000). This alone indicates that students will learn and communicate electronically more than any previous generation. At the same time, teenagers are not the only digital learners. With the growing number of online courses, the increasing accessibility of computers, and the increasing number of computer users, students of all ages are taking advantage of distance learning or are using computers to enhance the traditional classroom experience.

Two things emerge in the study of students’attitudes toward online learning: individual situations impact students’ perceptions of computer-based learning, and students’ varied individual characteristics make it difficult to define their perceptions conclusively. For example, some students have their own computers, while others rely on computer labs. Such variation in computer access can result in attitudinal differences. In addition, the purpose of computer use varies. Distance education courses, for example, use computers in different ways than traditional classrooms, which can also affect students’ perceptions. A wide variety of achievement levels and attitudes exist among both online and traditional learners. Although an illusory “typical learner” exists, a variety of factors, including students’ gender, age, and motivation, could explain different reactions among the student population.

1).According to the passage, what does "digital learners" mean？（）

A、Learners of mathematics

B、Learners of information technology

C、Computer users

D、Online learners

2).What will make online learning more and more popular？（）

A、The crowded classrooms

B、The lower cost of computers

C、The increase of computer users

D、The previous generations interest in digital communication

3).Which of the following is the main factor that makes it difficult to define students'' perceptions of online learning definitely？（）

A、Learners'' varied locations

B、Learners'' varied characteristics

C、Learners'' varied communication skills

D、Learners'' varied experiences

4).What is the author''s attitude towards online learning？（）

A、cautious

B、indifferent

C、positive

D、negative

5).Who may become online learners？（）

A、Mainly teenagers

B、Mostly college students

C、Only working people with their own computers

D、People of all ages and backgrounds
