The Great Energy Debate

Modern civilization is heavily dependent on energy. Without reliable power sources, e coulnt operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy.

Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward.

Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap.

The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. I they happen to have a meltdown, this could destroy the surrounding area for years to come.

The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

The work “spotlight” in paragraph 5 is closest in meaning to __________.

A. concern

B. attention

C. danger

D. area of light

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

In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.

Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future. 

From the passage, it can be inferred that to solve our energy problems ________ . 

A. a combination of conservation and invention will be needed 

B. we will have to stop using many of our modern conveniences 

C. scientists will have to find ways to increase our supplies of coal, oil, and gas 

D. scientists will have to find one major source of nonpolluting energy

B. chúng tôi sẽ phải ngừng sử dụng nhiều tiện ích hiện đại của chúng tôi

C. các nhà khoa học sẽ phải tìm cách tăng nguồn cung than, dầu và khí đốt của chúng ta

D. các nhà khoa học sẽ phải tìm một nguồn năng lượng không gây ô nhiễm chính

Thông tin: Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.

Tạm dịch: Những nỗ lực bảo tồn cùng với các nguồn năng lượng tái tạo, như sự kết hợp của năng lượng mặt trời, nước, gió và địa nhiệt và nhiên liệu thay thế, như rượu và hydro, sẽ đảm bảo cung cấp năng lượng sạch, giá cả phải chăng cho tương lai của nhân loại.

Dịch bài đọc:

Trong thế kỷ XX, con người phụ thuộc vào năng lượng vô hạn để cung cấp năng lượng cho cuộc sống hàng ngày của họ. Một loạt các thiết bị chạy năng lượng và tiện nghi hiện đại được coi là điều hiển nhiên, và mặc dù có vẻ như chúng ta sẽ không bao giờ gặp nguy hiểm khi sống nếu không có những tiện ích đó, thực tế là nhiều nguồn cung cấp năng lượng đang cạn kiệt nhanh chóng. Các nhà khoa học không ngừng tìm kiếm các nguồn năng lượng mới để duy trì xã hội hiện đại. Việc dân số trong tương lai có tiếp tục được hưởng những lợi ích của năng lượng dồi dào hay không sẽ phụ thuộc vào sự thành công của tìm kiếm này.

Than, dầu, và khí đốt tự nhiên cung cấp hầu hết năng lượng của nó cho nền văn minh hiện đại. Tuy nhiên, không chỉ nguồn cung cấp các loại nhiên liệu này bị hạn chế mà chúng còn là nguồn gây ô nhiễm chính. Nếu nhu cầu năng lượng trong tương lai được đáp ứng mà không gây hại nghiêm trọng đến môi trường, các nguồn năng lượng thay thế hiện tại phải được cải thiện hoặc tiếp tục khám phá và phát triển. Chúng bao gồm hạt nhân, nước, năng lượng mặt trời, gió và năng lượng địa nhiệt, cũng như năng lượng từ các loại nhiên liệu mới, không gây ô nhiễm. Tuy nhiên, mỗi phương án đều có ưu điểm và nhược điểm.

Các nhà máy điện hạt nhân sản xuất một cách hiệu quả lượng điện lớn mà không gây ô nhiễm bầu khí quyển; tuy nhiên, chúng rất tốn kém để xây dựng và bảo trì, và chúng đặt ra vấn đề nan giải là phải làm gì với chất thải hạt nhân. Thủy điện là không tốn kém và an toàn với môi trường, nhưng không thực tế đối với các cộng đồng ở xa nước di chuyển. Khai thác năng lượng từ thủy triều và sóng có nhược điểm tương tự. Năng lượng mặt trời hứa hẹn rất lớn cho tương lai nhưng các phương pháp thu thập và tập trung ánh sáng mặt trời vẫn chưa hiệu quả, cũng như các phương pháp khai thác năng lượng gió.

Mỗi nguồn năng lượng đều có nhược điểm của nó. Một cách để giảm thiểu chúng là sử dụng ít năng lượng hơn. Những nỗ lực bảo tồn cùng với các nguồn năng lượng tái tạo, như sự kết hợp của năng lượng mặt trời, nước, gió và địa nhiệt và nhiên liệu thay thế, như rượu và hydro, sẽ đảm bảo cung cấp năng lượng sạch, giá cả phải chăng cho tương lai của nhân loại.

In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.

Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future. 

The passage suggests that _______ . 

A. people use energy without giving great thought to where it's coming from 

B. modern society requires a minimum amount of energy to keep it running 

C. the search for energy sources is mainly a problem for the future 

D. scientists believe we will never have to go without our modern conveniences
