Question 1 - 8.
Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the questions.
For many years, scientists have been arguing about global warming. While they don't all agree about what this might mean for Planet Earth, many think it is going on - and that we can do something about it. We need a few more years to gather facts before anyone can say for sure. But people need to start now to do things to stop it.
There are many types of gases in our atmosphere. Some of them absorb the heat from the sun and control our climate. "Greenhouse gases" are those that hold the heat around the planet's surface. When we increase the level of these gases, we upset the balance. These extra gases trap even more heat.
Some scientists say global warming has already started to change the environment. The Earth's temperature has risen one degree Fahrenheit this century. Many scientists believe it could rise from two to eight degrees Fahrenheit in the next hundred years. This would be the fastest rise in 10,000 years. Sea levels could rise. Ice sheets could melt and add to the water level. Many places near the coast would be in danger of flooding.
If the climate changes rapidly and severely, it can cause significant harm to some plants and animals. They could even die out. Weather could become more violent and extreme. In some places there would be more forest fires. But in other areas there would be more rain and snow, storms and floods.
Which of the following is TRUE according to the passage?
Scientists say that global warming hasn't affected the environment yet.
Scientists have all agreed about global warming.
Climate change would cause forest fires everywhere.
As the levels of these gases grow, they absorb more heat.
Giải thích chi tiết
Áp dụng 😎 Linearthinking để đối chiếu từng đáp án với thông tin trong bài:
A. SV - các nhà khoa học nói rằng Scientists say that S - hiện tượng nóng lênglobal warming V - chưa ảnh hưởng môi trườnghasn't affected the environment yet
Khoanh vùng thông tin:
Keyword: "Scientists", "global warming", "affected the environment" → Đoạn 3: “Some scientists say global warming has already started to change the environment.”
So sánh:
Bài đọc: global warming đã bắt đầu làm thay đổi môi trường
Option: global warming chưa ảnh hưởng đến môi trường → already started to change ≠ hasn't affected yet → ❌ Sai
B. S - các nhà khoa học Scientists V - đều đã đồng ý về hiện tượng nóng lên toàn cầu have all agreed about global warming
Khoanh vùng thông tin:
Keyword: "Scientists", "all agreed", "global warming" → Đoạn 1: “For many years, scientists have been arguing about global warming. While they don't all agree about what this might mean for Planet Earth...”
So sánh:
Bài đọc: scientists không hoàn toàn đồng ý
Option: scientists đều đồng ý → don't all agree ≠ have all agreed → ❌ Sai
C. S - biến đổi khí hậu Climate change V - sẽ gây cháy rừng ở mọi nơi would cause forest fires everywhere
Khoanh vùng thông tin:
Keyword: "Climate change", "forest fires", "everywhere" → Đoạn 4: “In some places there would be more forest fires. But in other areas there would be more rain and snow, storms and floods.”
So sánh:
Bài đọc: Ở một số nơi → nhiều cháy rừng hơn
Option: mọi nơi → cháy rừng → in some places ≠ everywhere → ❌ Sai
D. Time - khi mức các khí này tăng As the levels of these gases grow , S - các khí này they V - giữ lại nhiều nhiệt hơn absorb more heat
Khoanh vùng thông tin:
Keyword: "levels of these gases grow", "absorb more heat" → Đoạn 2: “When we increase the level of these gases, we upset the balance. These extra gases trap even more heat.”
So sánh:
Bài đọc: lượng khí nhà kính tăng → giữ lại nhiều nhiệt hơn
Option: levels of these gases grow → hấp thụ nhiều nhiệt hơn → trap even more heat = absorb more heat → ✅ Đúng
