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.
Scientists have identified two ways in which species disappear. The first is through ordinary or "background" extinctions, where species that fail to adapt are slowly replaced by more adaptable life forms. The second is when large numbers of species go to the wall in relatively short periods of biological time. There have been five such extinctions, each provoked by cataclysmic evolutionary events caused by some geological eruption, climate shift, or space junk slamming into the Earth. Scientists now believe that another mass extinction of species is currently under way - and this time human fingerprints are on the trigger.
How are we doing it? Simply by demanding more and more space for ourselves. In our assault on the ecosystems around us we have used a number of tools, from spear and gun to bulldozer and chainsaw. Certain especially rich ecosystems have proved the most vulnerable. In Hawaii more than half of the native birds are now gone - about 50 species. Such carnage has taken place all across the island communities of the Pacific and Indian oceans. While many species were hunted to extinction, others simply succumbed to the introduced predators" that humans brought with them: the cat, the dog, the pig, and the rat.
Today the tempo of extinction is picking up speed. Hunting is no longer the major culprit, although rare birds and animals continue to be butchered for their skin, feathers, tusks, and internal organs, or taken as savage pets. Today the main threat comes from the destruction of the habitat of wild plants, animals, and insects need to survive. The draining and damming of wetland and river courses threatens the aquatic food chain and our own seafood industry. Overfishing and the destruction of fragile coral reefs destroy ocean biodiversity. Deforestation is taking a staggering toll, particularly in the tropics where the most global biodiversity is at risk. The shrinking rainforest cover of the Congo and Amazon River basins and such place as Borneo and Madagascar have a wealth of species per hectare existing nowhere else. As those precious hectares are drowned or turned into arid pasture and cropland, such species disappear forever.

Tạm dịch: Đã có năm cuộc tuyệt chủng như vậy, mỗi sự kiện bị gây ra bởi các sự kiện tiến hóa thảm khốc bởi một số vụ phun trào địa chất, biến đổi khí hậu hoặc rác vũ trụ rơi xuống Trái đất. Các nhà khoa học hiện tin rằng một cuộc tuyệt chủng hàng loạt khác đang tiếp diễn - và lần này thì có dính dáng đến bàn tay con người.
Chọn B.
Dịch bài đọc:
Các nhà khoa học đã xác định được hai cách mà các loài vật biến mất. Cách đầu tiên là thông qua sự tuyệt chủng thông thường hay “do những yếu tố tự nhiên”, trong đó các loài vật không thích nghi được từ từ bị thay thế bởi các dạng sống khác có khả năng thích nghi hơn. Thứ hai là khi một số lượng lớn các loài đi đến tuyệt chủng trong khoảng thời gian sinh học tương đối ngắn. Đã có năm cuộc tuyệt chủng như vậy, mỗi sự kiện bị gây ra bởi các sự kiện tiến hóa thảm khốc bởi một số vụ phun trào địa chất, biến đổi khí hậu hoặc rác vũ trụ rơi xuống Trái đất. Các nhà khoa học hiện tin rằng một cuộc tuyệt chủng hàng loạt khác đang tiếp diễn – và lần này thì có dính dáng đến bàn tay con người.
Chúng ta đang làm điều đó như thế nào? Đơn giản bằng cách đòi hỏi ngày càng nhiều không gian cho bản thân. Trong cuộc tấn công của chúng ta vào các hệ sinh thái xung quanh, ta đã sử dụng một số công cụ, từ giáo và súng cho đến máy ủi và cưa máy. Một số hệ sinh thái phong phú nhất định đã chứng minh rằng chính bản thân chúng là dễ bị tổn hại nhất. Ở Hawaii, hơn một nửa số lượng chim bản địa đã biến mất – khoảng 50 loài. Cuộc tàn sát như vậy đã diễn ra trên khắp các quần đảo của Thái Bình Dương và Ấn Độ Dương. Trong khi nhiều loài bị săn bắn đến tuyệt chủng, những loài khác chỉ đơn giản là bị khuất phục trước “những kẻ săn mồi được du nhập” mà con người mang theo: mèo, chó, lợn và chuột.
Ngày nay, tốc độ tuyệt chủng đang tăng nhanh. Việc săn bắn không còn là nguyên nhân chính nữa, mặc dù các loài chim và động vật quý hiếm tiếp tục bị giết để lấy da, lông, ngà và các cơ quan nội tạng, hoặc được coi như những con thú cưng hung dữ. Ngày nay, mối đe dọa chủ yếu đến từ sự phá hủy môi trường sống của thực vật hoang dã, động vật và côn trùng cần để tồn tại. Việc thoát nước và phá hủy các vùng đầm lầy và sông ngòi đe dọa chuỗi thức ăn thủy sản và ngành thủy sản của chúng ta. Đánh bắt quá mức và phá hủy các rạn san hô mỏng manh đã phá hủy đa dạng sinh học ở đại dương. Phá rừng đang gây ra nhiều thiệt hại một cách khủng khiếp, đặc biệt là ở vùng nhiệt đới nơi đa dạng sinh học toàn cầu có nguy cơ cao nhất. Các khu rừng mưa nhiệt đới đang dần thu hẹp của các lưu vực sông Congo và Amazon và những nơi như Borneo và Madagascar có vô số loài trên mỗi hecta mà không tồn tại ở một nơi nào khác. Khi những hecta quý giá đó bị ngập nước hay biến thành đồng cỏ khô cằn và đất canh tác, những loài vật như vậy sẽ biến mất mãi mãi.

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.
Who talk more men or women? Most people believe that women talk more. However, linguist Deborah Tannen, who has studied the communication style of men and women, says that this is a stereotype. According to Tannen, women are more verbal - talk more in private situations, where they use conversation as the “glue” to hold relationships together. But, she says, men talk more in public situations, where they use conversation to exchange information and gain status. Tannen points out that we can see these differences even in children. Little girls often play with one "best friend", their play includes a lot of conversation. Little boys often play games in groups; their play usually involves more doing than talking. In school, girls are often better at verbal skills, boys are often better at mathematics.
A recent study at Emory University helps to shed light on the roots of this difference. Researchers studied conversations between children aged 3-6 and their parents. They found evidence that parents talk very differently to their sons than they do to their daughters. The startling conclusion was that parents use more language with their girls. Specifically, when parents talk with their daughters, they use more descriptive language and more details. There is also far more talk about emotions, especially with daughters than with sons.
