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.

 

          Experts in climatology and other scientists are becoming extremely concerned about the changes to our climate which are taking place. Admittedly, climate changes have occurred on our planet before. For example, there have been several ice ages or glacial periods.
          These climatic changes, however, were different from the modern ones in that they occurred gradually and, as far as we know, naturally. The changes currently being monitored are said to be the result not of natural causes, but of human activity. Furthermore, the rate of change is becoming alarmingly rapid.
          The major problem is that the planet appears to be warming up. According to some experts, this warming process, known as global warming, is occurring at a rate unprecedented in the last 10,000 years. The implications for the planet are very serious. Rising global temperatures could give rise to such ecological disasters as extremely high increases in the incidence of flooding and of droughts. These in turn could have a harmful effect on agriculture.
          It is thought that this unusual warming of the Earth has been caused by so-called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of the sun is trapped. This leads to the warming up of the planet.
          Politicians are also concerned about climate change and there are now regular summits on the subject, attended by representatives from around 180 of the world’s industrialized countries. Of these summits, the most important took place in Kyotoin Japanin 1997. There it was agreed that the most industrialized countries would try to reduce the volume of greenhouse gas emissions and were given targets for this reduction of emissions.
          It was also suggested that more forests should be planted to create so-called sinks to absorb greenhouse gases. At least part of the problem of rapid climate change has been caused by too drastic deforestation.
          Sadly, the targets are not being met. Even more sadly, global warnings about climate changes are often still being regarded as scaremongering

Greenhouse gases cause the warming up of the Earth because they _______.

A. are emitted by car engines

B. trap heat from the sun

C. do not add to atmosphere pollution

D. are unusual gases

Dựa theo đoạn văn, điều gì là KHÔNG đúng?
A. Khí CO2 là một trong những loại khí gas mà có thể gây hiệu ứng nhà kính.
B. Cái tạo bởi rừng có thể hấp thụ khí gây ra hiệu ứng nhà kính.
C. Vấn đề về nhanh biến đổi khí hậu đã bị gây ra chủ yếu do nạn phá rừng.
D. Chính trị gia là trong số những người lo lắng về biến đổi khí hậu.
Giải thích:
Nội dung câu A được đề cập đến trong câu 1 đoạn 6. “It was also suggested that more forests should be planted to create so-called sinks to absorb greenhouse gases.” (Nó cũng là gợi ý rằng rừng hơn nên trồng để tạo “cái bồn” để hấp thụ khí gây ra hiệu ứng nhà kính.)
Nội dung câu B được đề cập đến trong câu 1 đoạn 5. “It is thought that this unusual warming of the Earth has been caused by so-called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example.” (Người ta nghĩ rằng sự nóng lên toàn cầu của Trái đất điều này là do khí gây ra hiệu ứng nhà kính, cái gọi là, như các - bô - ních, được phát ra vào không khí bằng xe hơi động cơ và quy trình công nghiệp hiện đại, chẳng hạn.)
Nội dung câu D được đề cập đến trong câu 2 đoạn 4. “Such gases not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of the sun is trapped. This leads to the warming up of the planet.” (Khí như vậy không những thêm vào ô nhiễm không khí, mà còn tạo hiệu ứng nhà kính, theo đó sức nóng của mặt trời bị mắc kẹt. Điều này dẫn đến sưởi ấm lên của hành tinh. )
Nội dung câu C không đúng với bài : At least part of the problem of rapid climate change has been caused by too drastic deforestation. -> hiện tượng phá rừng chỉ là một trong những nguyên nhân chứ không phải nguyên nhân chủ yếu

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 28 to 34.

Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth's ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.

Certainly, there have been periods in Earth's history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.

However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes selves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments
According to the passage, natural evolutionary change is different from changes caused by humans in that changes caused by humans___________.

A. affect fewer ecosystems

B. are occurring at a much faster rate

C. are reversible

D. are less devastating to most species

As the human population continues to expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.

  Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.

  However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments.

According to the passage, natural evolutionary change is different from changes caused by humans in that changes caused by humans _____________ .

A. affect fewer ecosystems

B. are occurring at a much faster rate 

C. are reversible 

D. are less devastating to most species
