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 from 38 to 42.

  The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb - fox squirrels in one place, red squirrels in another, gray squirrels in a third - for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present. There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate.

Which of the following conclusions about squirrels is supported by information in the passage?

A. The competition among the three species is intense. 

B. Fox squirrels are more common than grey or red squirrels. 

C. Two species of squirrels seldom inhabit the same suburb. 

D. The reasons why squirrels do well in the suburbs are unknown

Đáp án A

Nhà văn ám chỉ động vật có vú ở ‘rừng ngoại ô’ khác với các loài cây cùng ở đó trên rên phương diện nào..

A. chúng ko được giới thiệu , đưa vào có chủ đích

B. con người không quan tâm, mong muốn chúng

C. chúng ko hiện hiện với số loài lớn

D. chúng ko thích nghi với điều kiện ngoại ô

Dẫn chứng: “The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside’ (những loài cây được lòng con người và chúng được trồng có chủ đích. Còn những loài động vật có vú như thỏ,chồn thì tới từ những vùng nông thôn xung quanh)

Dịch bài

Cộng đồng sinh vật thay đổi lại khi 1 loài chuyển từ thành phố tới ngoại ô. Bao quanh những thành phố là 1 quần xã sinh vât được gọi là ‘rừng ngoại ô’. Những loài cây trong rừng là những loài được lòng con người, chúng được trồng và chăm sóc có chủ đích. Những động vật có vú như như thỏ,chồn thì tới từ những vùng nông thôn xung quanh. Gấu trúc trở thành chuyên gia trong việc cậy bới thùng rác, thậm chí nai đi lang thang trên các tuyến đường phố. Một vào loài sóc thích nghi tốt với vùng ngoại ô, nhưng chỉ có 1 loài là chiếm ưu thế trong bất kì 1 khu vực ngoại ô nào đó- loài sóc cáo ở 1 vùng, sóc đỏ ở 1 vùng khác và sóc xám ở 1 vùng thứ 3 -lí do này nay vẫn chưa giải thích được. Sự da dạng số loài chim ở ngoại ô là rất lớn, và ở miền Nam, thằn lằn phát triển mạnh mẽ ở vườn và thậm trí trong nhà. Đương nhiên, côn trùng thì vẫn luôn hiện diện.

Có sự giống nhau kì lại về mặt sinh học trên những quần xa ngoại ô này. Thật vật, sự giàu tài nguyên sinh vật ở Los Angeles đang mất dần từ Boston, và có những loài côn trùng ở Miami không được tìm thấy ở Seattle. Nhưng ở những vùng rộng lớn của Hoa Kỳ, các điều kiện sinh thái ở quần xã sinh vật ngoại ô biến đổi ít hơn nhiều so với quần xã sinh vật tự nhiên. Và không giống như quần xã sinh vật tự nhiên, cộng đồng sinh vật thành thị và ngoại ô tồn tại không bị ảnh hưởng bởi khí hậu.

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

Read the following passages and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions

The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb -fox squirrels in one place, red squirrels in another, gray squirrels in a third - for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present. There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate

The author implies that the mammals of the "suburban forest" differ from most species of trees there in which of the following ways?

A. They were not deliberately introduced

B. They are considered undesirable by humans

C. They are represented by a greater number of species

D. They have not fully adapted to suburban conditions

Dân chứng: “The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside’ (những loài cây được lòng con người và chúng được trồng có chủ đích. Còn những loài động vật có vú như thỏ,chồn thì tới từ những vùng nông thôn xung quanh)
