Among the factors cited to explain this phenomenon are the lack of exposure of high school students to the very idea of engineering and the fact that many have insufficient mathematics and science background to gain entrance to engineering school, even if they do identify the profession as a possible career. This is unfortunate, for the ideas of engineering should be integrated into the curricula not only of high schools but also of middle and primary schools. Our children are being done a disservice by not being exposed properly throughout their education to engineering activities identified as such.

After all, even pre-school children have the prerequisites in their play for appreciating exactly what engineering is: design, Indeed, design is everywhere around them throughout their school day, even in their before-school and after-school activities. It need only be pointed out to them that they designing something, and therefore being engineering of sorts, in virtually everything that they do

Read the followingpassage carefully and then choose the best answer to each question.

Butterflies are among the most extensively studied insects - an estimated 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.

Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions.

For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed.

A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates, In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.

In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.

Which aspect of butterflies does the passage mainly discuss?

A. Their adaptation to different habitats

B. Their names 

C.Their physical characteristics

D. Their variety

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 36 to 42.

Diversity is a hallmark of life, an intrinsic feature of living systems in the natural world. The demonstration and celebration of this diversity is an endless rite. Look at the popularity of museums, zoos, aquariums and botanic gardens. The odder the exhibit, the more different it is from the most common and familiar life forms around us, the more successful it is likely to be. Nature does not tire of providing oddities for people who look for them. Biologists have already formally classified 1.7 million species. As many as 30 to 40 million more may remain to be classified. (1)

Most people seem to take diversity for granted. If they think about it at all they assume it exists in endless supply. Nevertheless, diversity is endangered as never before in its history. Advocates of perpetual economic growth treat living species as expendable. As a result an extinction crisis of unprecedented magnitude is under way. Worse yet, when diversity needs help most, it is neglected and misunderstood by much of the scientific community that once championed it. (2)

Of the two great challenges to the legitimacy of this diversity, the familiar one comes primarily from economists. Their argument, associated with such names as Julian Simon, Malcolm McPherson and the late Herman Kahn, can be paraphrased: "First, if endangered species have a value as resources - which has been greatly exaggerated - then we should be able to quantify that value so that we can make unbiased, objective decisions about which species, if any, we should bother to save, and how much the effort is worth. Secondly, the global threat to the diversity of species, particularly in the tropics, has been overestimated. Thirdly, we have good substitutes for the species and ecosystems that are being lost, and these substitutes will nullify the damage caused by the extinctions". (3)

The structure of the argument seems to me to be identical in form to that of an old joke from the American vaudeville circuit. One elderly lady complained to another about her recent vacation at a resort in the Catskill Mountains in New York State. "The food was terrible", she moaned. "Pure poison, I couldn't eat a bite. And the portions were so tiny!" (4)

Species may be valuable, but not especially so, and the threat to them has been exaggerated. But this does not matter anyway, say the economists, because we can replace any species that vanishes.(5)

It is not clear how much of an impact this argument has on the informed public, but it has certainly provoked an outcry among scientific conservationists. It has set the terms for, and dominated, most of the pro-diversity literature of the past few years, making it a literature of response, thus limiting its scope and creative force.

Question 42: The position of the scientific conservationists has been weakened because they have _________.

A. adopted the economists' arguments.

B. failed to communicate with public.

C. lost the initiative in the debate.

D. protested too loudly.

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.

Butterflies are among the most extensively studied insects - an estimated 90 percent of the world's species have scientific names. As a consequence, they are perhaps the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity.

Perhaps the aspect of butterfly diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions.

For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterfly richness has been well confirmed.

A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather man between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates, In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase.

In documenting geographical variation in butterfly diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfly distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized.

Butterflies are a good example for communicating information about conservation issues because they ______.

A. are simple in structure

B. have been given scientific names

C. are viewed positively by people

D. are found mainly in temperate climates
