Theo đoạn văn _____.

A. không có thiết bị năng lượng mặt trời được hỗ trợ đã được phát triển cho đến nay.

B. bên cạnh xe năng lượng mặt trời, chúng ta cũng đã phát triển các thiết bị năng lượng mặt trời.

C. kế hoạch năng lượng mặt trời là khả thi hơn so với kế hoạch năng lượng gió.

D. thủy triều có thể cung cấp năng lượng nhiều hơn mặt trời.

Thông tin:Despite the appearance that solar energy may be the least, feasible among the current crop of alternative fuel propositions, new solar powered devices and more specifically solar powered cars are beginning to be developed.

Tạm dịch:Mặc dù sự xuất hiện năng lượng mặt trời có thể là thực hiện được, ít nhất là giữa các vụ thu hoạch  hiện tại của kế hoạch thay thế nhiên liệu, các thiết bị năng lượng mặt trời mới và cụ thể hơn các loại xe chạy bằng  năng lượng mặt trời đang bắt đầu được phát triển.

=>According to the text, besides solar car, we have also developed solar powered devices.

Câu 5:

Read the passage below and choose one correct answer for each question.

In the future, maybe all cars that run on petrol will be replaced by solar cars, which have been around for a while, but with recent developments in solar car design and the measurement of photovoltaic cells becoming smaller, the dream of a truly efficient solar car is more reality than fantasy. A solar car is a vehicle powered by photovoltaic cells, also called solar cells, which convert sunlight (light energy) into electrical energy. As a source of energy on earth, there is nothing like the sun: in a mere one thousandth of one second (.001) , the sun emits enough energy to fulfill our planet's energy needs for the next 5,000 years. It is a staggering fact, and an exciting one. Since the energy from the sun is responsible for renewable resources such as wind, tides, and heat, solar energy seems to offer the brightest future for not only cars, but for the entire energy crisis. Despite the appearance that solar energy may be the least, feasible among the current crop of alternative fuel propositions, new solar powered devices and more specifically solar powered cars are beginning to be developed. How do Solar Cars work?

The photovoltaic cells absorb photons from sunlight. This action generates heat, which the cells then convert into electrical energy and stores in an onboard battery. This process of conversion is called the photovoltaic effect. Not surprisingly, such a vehicle has zero emissions, and is very environmentally friendly. Unfortunately, at the moment photovoltaic cells are extremely inefficient, yet as time progresses the efficiency of these cells will grow. This will make solar energy and solar cars the fuel and car of the future - a closer reality.
