I. Read the passage and circle the letter A, B, C or D to indicate the correct answer to each of the following questions. (2 points)

As more women in the United States move up the professional ladder, more are finding it necessary to make business trips alone. Since this is new for many, some tips are certainly in order . If you are married, it is a good idea to encourage your husband and children to learn to cook few simple meals while you are way. They will be much happier and probably they will enjoy the experience. If you will be eating alone a good deal, choose good restaurants. In the end, they will be much better for your digestion. You may also find it useful to call  the restaurant in advance and state that you will be eating alone. You will probably get better service and almost certainly a better table. Finally, and most importantly, anticipate  your travel needs as a businesswoman; this starts with lightweight luggage which you can easily manage even when fully packed. Take a folding case inside your suitcase; it will come in extremely handy for dirty clothes, as well as for business documents and papers you no longer need on the trip. And makes sure you have a briefcase so that you can keep currently required papers separate. Obviously, experience helps, but you make things easier on yourself from the first by careful planning, so that right from the start you really can have a good trip!

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 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.

According to the passage, which of the following is true about solar power?

A. There is very little of it available in Iceland.

B. It is being used in 100, 000 private homes worldwide.

C. It is 6,000 times more powerful than energy from fossil fuels.

D. There is enough of it to far exceed the energy needs of the world.

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.

Đáp án A.

Tạm dịch: we must begin to put a greater priority on harnessing alternative energy sources: chúng ta phải bắt đầu ưu tiên nhiều hơn cho việc khai thác các nguồn năng lượng thay thế

A. capturing: lấy được, giành được

B. harassing: gây lo lắng, quy rầy

C. depleting: làm suy yếu, cạn kiệt

D. exporting: xuất khẩu
