Đáp án B.

Tạm dịch: Israel, Ấn Độ và Pakistan thường được cho là có sở hữu vũ khí hạt nhân, loại vũ khí chỉ sử dụng sự phân hạch nguyên tử,

Cấu trúc bị động đặc biệt:

People/ they + say/ thinjk /believe… + (that) + S + V + O.

Cách 1: It + to be (chia cùng thì với say/ think/ believe) + said/ thought/ believed … + that + S + V.

Ex: People said that he was nice to his friends.

→ It was said that he was nice to his friends.

Cách 2: S + to be ( chia cùng thì với say/ think/ believe) + said/ thought/ believed… + to V + O.

Ex: People said that he was nice to his friends.

→: He was said to be nice to his friends.

Nếu động từ ở mệnh đề sau “that” xảy ra trước động từ ở mệnh đề trước “that”

Thì chuyển về dạng to have PP.

Ex: People said that he had been nice to his friends.

→ He was said to have been nice to his friends.

Xét câu đề bài: (… are generally believed to have …) ta thấy động từ phía sau ở dạng “to V” nên khi chuyển sang dạng bị động bắt đầu với It thì động từ sau “that” phải cùng thì HTĐ như động từ trước “that”.

Vậy ta chọn đáp án B

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.

        Sunlight is solar energy. Sunlight is needed for growing plants that you eat to get energy. Sunlight is also used to make clean electricity. Burning fossil fuels to make electricity pollutes our atmosphere and rivers. Fossil fuels are expensive and limited sources of energy. Nuclear fission is used to create enormous amount of heat and electricity. However, nuclear fission forms dangerous radioactive waste.

          Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators.

Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station. PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars.

          Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam. CSP power plants can store large amount of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also burn natural gas to provide the heat that is used to turn water into steam.

         Sunlight provides the energy needed to grow plants and make large amount of environmentally friendly heat and electricity. Solar energy can provide power today and for a long time in the future.

The drawback of nuclear fission is that ________

A. it sends out energy in the form of rays that can be harmful.

B. it is costly.

C. it releases smoke.

D. it is time-consuming to be formed.

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

Đáp án D.

Dịch câu hỏi: Từ “these” trong đoạn 3 đề cập đến _________.

A. sản xuất điện

B. tìm kiếm năng lượng xanh hơn

C. năng lượng rẻ

D. năng lượng thay thế

Thông tin: “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.”

(Năng lượng xanh là một lựa chọn đang ngày càng trở nên hấp dẫn. Nó bao gồm những công nghệ như năng lượng mặt trời, năng lượng gió và thủy năng. Chúng được xem là những nguồn năng lượng sạch bởi chúng gây ra rất ít ô nhiễm.)

=> Dựa vào nghĩa, có thể thấy "these" ở đây chỉ những nguồn năng lượng xanh, hay năng lượng thay thế đã được nhắc đến trước đó. Các đáp án còn lại không hợp lý.
