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 36 to 42.

    It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species’ death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food Resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.

    The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time – a mass extinction. One of the best-known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago. When approximately 95 percent of all species died, mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.

          One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. This periodic extinction might be due to intersection of the Earth’s orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species’ survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random events

The word “it” in line 2 refers to 

A. environment 

B. species 

C. extinction 

D. 99 percent

Đáp án B

 Từ “it” ở dòng 2 nhắc tới ________.

A. môi trường

B. loài

C. sự tuyệt chủng

D. 99%

Giải thích: Thông tin nằm ở “When a species is no longer adapted to a changed environment, it may perish” - Khi một loài không còn thích nghi với môi trường đã thay đổi, nó sẽ biến mất. Như vậy. nó ở đây chính là loài động vật đó

DỊCH NGHĨA

    Người ra ước tính rằng hơn 99 phần trăm tất cả các loài từng tồn tại đã bị tuyệt chủng. Điều gì gây ra sự tuyệt chủng? Khi một loài không còn thích nghi với môi trường đã thay đổi, nó có thể biến mất. Các nguyên nhân chính dẫn đến một loài chết đi khác nhau đối với các trường hợp khác nhau. Sự thay đổi hệ sinh thái quá nhanh có thể khiến môi trường sống trở nên khó khăn với các loài đó. Ví dụ, nhiệt độ có thể thay đổi mà một loài không thể thích nghi. Nguồn thức ăn có thể bị ảnh hưởng bởi những thay đổi của môi trường, sau đó sẽ tiếp tục gây ra những vấn đề khác cho loài mà cần sử dụng nguồn thức ăn này. Các loài khác có thể thích nghi tốt hơn với môi trường, dẫn đến sự cạnh tranh và cuối cùng là cái chết của một loài nào đó.

    Các mẫu hóa thạch cho thấy rằng sự tuyệt chủng đã xảy ra trong suốt lịch sử của trái đất. Phân tích gần đây cũng tiết lộ rằng trong một số trường hợp nhiều loài đã tuyệt chủng cùng một lúc - tuyệt chủng hàng loạt. Một trong những ví dụ nổi bật của tuyệt chủng hàng loạt xảy ra vào 65 triệu năm trước đây với sự sụp đổ của khủng long và nhiều sinh vật khác. Có lẽ lần tuyệt chủng hàng loạt lớn nhất xảy ra vào 225 triệu năm trước đây, khi khoảng 95 phần trăm số loài đã chết. Tuyệt chủng hàng loạt có thể bị gây ra bởi sự thay đổi tương đối nhanh chóng của môi trường và có thể trở nên tồi tệ hơn bởi các mối liên hệ mật thiết giữa các loài. Ví dụ, nếu một điều gì đó đã xảy ra và tiêu diệt nhiều sinh vật phù du trong các đại dương, sau đó hàm lượng oxy của trái đất sẽ giảm, thậm chí ảnh hưởng đến các sinh vật không sống trong đại dương. Một sự thay đổi như vậy có thể sẽ dẫn đến sự tuyệt chủng hàng loạt.

          Một khám phá thú vị, và cũng gây ra nhiều tranh cãi, đó là sự tuyệt chủng trong suốt 250 triệu năm qua đã có xu hướng tăng mạnh mẽ hơn su mỗi 26 triệu năm. Sự tuyệt chủng có chu kì này có thể là do giao điểm của quỹ đạo trái đất với một đám mây sao chổi, nhưng thuyết này hoàn toàn chỉ là suy đoán. Một số nhà nghiên cứu cũng đã cho rằng sự tuyệt chủng thường là ngẫu nhiên. Nghĩa là một số loài bị loại bỏ và những loài khác có thể tiếp tục tồn tại mà không có lí do cụ thể nào. Sự tồn tại của một số loài có thể không liên quan gì đến khả năng thích nghi hay không thích nghi của chúng. Nếu vậy, một vài sự tiến hóa lịch sử có thể phản ảnh một chuỗi các sự kiện ngẫu nhiên quan trọng

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 43 to 50.

    Learning means acquiring knowledge or developing the ability to perform new behaviors. It is common to think of learning as something that takes place in school, but much of human learning occurs outside the classroom, and people continue to learn throughout their lives.

Even before they enter school, young children learn to walk, to talk, and to use their hands to manipulate toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to interact with their parents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for interacting with other children. After they finish school, people must learn to adapt to the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.

    Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human-service workers need to understand how certain experiences change people’s behaviors. Employers, politicians, and advertisers make use of the principles of learning to influence the behavior of workers, voters, and consumers.

    Learning is closely related to memory, which is the storage of information in the brain. Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later retrieves knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences.

          There are many forms of learning, ranging from simple to complex. Simple forms of learning involve a single stimulus. A stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch, or taste. In a form of learning known as classical conditioning, people learn to associate two stimuli that occur in sequence, such as lightning followed by thunder. In operant conditioning, people learn by forming an association between a behavior and its consequences (reward or punishment). People and animals can also learn by observation - that is, by watching others perform behaviors. More complex forms of learning include learning languages, concepts, and motor skills

According to the passage, what are children NOT usually taught outside the classroom? 

A. literacy and calculation 

B. life skills 

C. interpersonal communication 

D. right from wrong
