XV. Read the passage and answer the question.
A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.
Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.
1. What is a carbon footprint?

Choose A, B, C or D to indicate the underlined part that needs correction in each of the following questions.
Right now, a private company is developing something called ET3. ET3 stands for Evacuated Tube Transport Technology.
The ET3 system would reportedly be able to take passengers from New York to Beijing in just two hours. Here is how it works. A vacuum tube goes all the way from New York to Beijing. The tube is only a few meters wide. Capsules move through the tube. Six people can sit in one capsule. The capsules use electricity instead of gasoline. For international travel, the capsules can travel at about 6,500 kilometers per hour. That is much faster than an airplane!
So how can these capsules travel so fast? The answer is that there is no air inside the tube. When airplanes fly, they have to move through the air. The air resistance slows the airplanes down. Because there is no air in the ET3 tubes, the capsules are able to move at a very high speed. Besides, the capsules are quite light. They only weigh 183 kilograms.
Of course, ET3 doesn’t exist yet. Developers still have to solve a lot of problems. The biggest problem is that right now, ET3 would be far too expensive. In order to make ET3 cheaper, we will need much better technology. Maybe someday, you will be able to have lunch in New York and dinner in Beijing.
23. The word “works” in paragraph 2 is closest in meaning to ______.
a. travels b. operates c. earns money d. succeeds
24. According to the passage, which statement is NOT true.
a. Each ET3 capsule can carry up to six people.
b. We don’t know how to build its capsules
c. Speed in ET3 system is 6,500 km/h for international travel.
d. ET3 can travel a little faster than an airplane.
25. What can be inferred from the passage?
a. There is still a lot to do before putting ET3 into operation.
b. In the future, people will mainly use ET3 to travel abroad.
c. ET3 won’t be used domestically due to its high-cost
d. ET3 will soon be cheaper.
