In this era of increased global warming and diminishing fossil fuel supplies, we must begin to put a greater priority on harnessing alternative energy sources. Fortunately, there are a number of readily available, renewable resources that are both cost- effective and earth - friendly. Two such resources are solar power and geothermal power.
Solar energy, which reaches the earth through sunlight, is so abundant that it could meet the needs of worldwide energy consumption 6,000 times over. And solar energy is easily harnessed through the use of photovoltaic cells that convert sunlight to electricity. In the US alone, more than 100, 000 homes are equipped with solar electric systems in the form of solar panels or solar roof tiles. And in other parts of the world, including many developing countries, the use of solar system is growing steadily.
Another alternative energy source, which is abundant in specific geographical areas, is geothermal power, which creates energy by tapping heat from below the surface of the earth. Hot water and steam that are trapped in underground pools are pumped to the surface and used to run a generator, which produces electricity. Geothermal energy is 50,000 times more abundant than the entire known supply of fossil fuel resources and as with solar power, the technology needed to utilize geothermal energy is fairly simple. A prime example of effective geothermal use in Iceland, a region of high geothermal activity where there are over 80 percent of private homes, are heated by geothermal power.
Solar and geothermal energy are just two of promising renewable alternatives to conventional energy sources. The time is long overdue to invest in the development and use of alternative energy on global scale.
What does the author imply about alternative energy sources?

Trả lời:
Đáp án A.
Key words: imply, alternative energy sources
Clue: Solar and geothermal energy are just two of promising renewable alternatives to conventional energy sources: Năng lượng mặt trời và địa nhiệt chỉ là 2 trong số các loại năng lượng tải tạo đầy hứa hẹn có thể thay thế các nguồn năng lượng truyền thống.
Vậy đáp án chính xác là A. Many different types of alternative energy sources exist: Có nhiều nguồn năng lượng thay thế khác nhau
Các đáp án còn lại là sai:
B. Most alternative energy sources are too impractical for private use: Hầu hết các nguồn năng lượng thay thế quá phi thực tế để sử dụng cho mục đích cá nhân
C. Alternative energy is too expensive for developing countries to produce: Năng lượng thay thế quá đắt nên các nước đang phát triển không thể sản xuất được
D. Solar and geothermal energy are the effective forms of alternative power: Năng lượng mặt trời và năng lượng địa nhiệt là hai dạng năng lượng thay thế hiệu quả
