Explanation
The correct answer is "The Science Show" because in the conversation, the question asks for the name of the program and "The Science Show" is one of the options provided.
2.
2) The first kind of technology discussed in the conversation is _______________________.
Correct Answer
C. A trans-Atlantic tunnel
Explanation
The correct answer is a trans-Atlantic tunnel. The conversation discusses different kinds of technology, and one of them is a trans-Atlantic tunnel. This implies that the conversation is about various technological advancements, and specifically focuses on the concept of a tunnel connecting two continents.
3.
3) Which of the following statements is TRUE (Choose only one.)?
Correct Answer
B. The pre-constructed sections will be made on land.
Explanation
The correct answer is "The pre-constructed sections will be made on land." This means that the sections of the rail tunnel will be manufactured or built on land before being assembled or put together. This implies that the construction process will involve creating the sections in a controlled environment, potentially allowing for better quality control and efficiency.
4.
5) Which of the following is FALSE about the tunnel (Choose only one.)?
Correct Answer
B. A train that travels on tracks will run through the tunnel.
Explanation
The given statement is false because the passage does not mention anything about a train running through the tunnel. It only provides information about giant anchors holding the tunnel in place, the tunnel floating 200 meters under the surface, and the tunnel being built from pre-constructed sections. Therefore, the correct answer is that a train that travels on tracks will not run through the tunnel.

5) How are Maglev trains different from normal trains?
Correct Answer
C. They do not have wheels.
Explanation
Maglev trains differ from normal trains because they do not have wheels. Instead, they use magnetic levitation technology to float above the tracks, eliminating the need for wheels. This allows for a smoother and faster ride, as there is no friction between the train and the tracks. The absence of wheels also reduces maintenance and wear and tear on the tracks, making maglev trains more efficient and cost-effective in the long run.
6.
6) Where did the first Maglev train start being used?
Correct Answer
D. China
Explanation
The first Maglev train started being used in China.
7.
7) How fast do Maglev trains currently travel?
Correct Answer
A. 500 kilometers per hour
Explanation
Maglev trains currently travel at a speed of 500 kilometers per hour.
8.
8) TRUE or FALSE: Maglev trains produce less pollution than ordinary trains.
Correct Answer
A. True
Explanation
Maglev trains produce less pollution than ordinary trains. This is because maglev trains are powered by electricity and do not rely on fossil fuels like diesel or gasoline. As a result, they do not produce any direct emissions such as carbon dioxide or air pollutants. Additionally, maglev trains do not have traditional wheels that create friction with the tracks, reducing noise pollution as well. Therefore, it can be concluded that maglev trains are indeed less polluting compared to ordinary trains.
9.
9) Which of the following could be a problem with using Maglev trains (Choose only one.)?
Correct Answer
C. They are expensive to build.
Explanation
Maglev trains are known for their high construction costs. The technology used in Maglev trains, which involves magnetic levitation and propulsion, requires specialized infrastructure and materials. The construction of the tracks and the necessary electromagnets can be extremely expensive. Additionally, the maintenance and operation costs of Maglev trains are also high. Therefore, the high cost of building and maintaining Maglev trains can be a potential problem associated with their use.
10.
10) Which of the following is NOT a possible danger to underwater Maglev trains that is described in the conversation (Choose only one.)?
Correct Answer
C. A power outage
Explanation
The conversation discusses the potential dangers to underwater Maglev trains, and it mentions submarines, icebergs, and ocean waves as possible risks. However, a power outage is not mentioned as a danger to these trains. Therefore, the correct answer is a power outage.

Listen again to the excerpts from the conversation. Fill in the blanks with the correct words or combinations of words. Please do not put any marks (like . / ; , etc.) between your answers.11) Presenter: We have heard a lot _________________ extreme engineering and one _____________ amazing and astonishing ideas is a rail tunnel ___________ the Atlantic Ocean.
Correct Answer
recently about of the most under
Explanation
The sentence is discussing the topic of extreme engineering and mentions that one of the most amazing and astonishing ideas is a rail tunnel under the Atlantic Ocean. The correct answer fills in the blanks with "recently," "about," and "of the most under," which fits grammatically and makes sense in the context of the sentence.
12.
12) Presenter: Amazing. Now, __________________________, the train which would run through this tunnel ______________ a magnetically levitated train. _______________?
Correct Answer
as I understand it would be Is that right
Explanation
The presenter is confirming their understanding that the train which would run through the tunnel is a magnetically levitated train. They are asking if their understanding is correct.
13.
13) Martha Long: Well, ordinary trains travel on rails and they can only _______________ of around xxx kilometers per hour. They are also very noisy. Maglev trains _______________, so there's no noise. There's no pollution. The trains would be _____________________________.
Correct Answer
reach speeds don't use rails fast comfortable and quiet
Explanation
Maglev trains are a type of train that does not use rails, allowing them to reach high speeds. Unlike ordinary trains, they operate without making any noise, making the ride more comfortable and quiet. Additionally, since they don't use traditional fuel combustion engines, they produce no pollution. Therefore, the statement suggests that Maglev trains can reach high speeds, don't use rails, are fast, comfortable, and quiet.
