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 from 39 to 43.

Scientists have dreamed for a long time about building a 'flying train' which can float through the air above the tracks. With Maglev technology, their dreams are now a reality. Maglev trains have no wheels. Instead, powerful magnets lift them into the air and push them forward, at speeds of up to 500 km per hour.

As well as speed, Maglev has a number of advantages over other transport systems. The trains are quieter and the journey is smoother because they don't have wheels. They are also greener because they don't use fuel and so create less pollution. Right now there is only one high-speed Maglev train system in the world. It carries passengers from Shanghai city centre to the airport. However, work has started on a new, longer Maglev track in Japan. Trains will go from Tokyo to Nagoya in 40 minutes. But don't expect to ride on it on your next trip to Japan. It won't open until 2027! Then, in 2045, the line will extend to Osaka.

There is one major problem with Maglev technology: it is incredibly expensive to build the tracks. Transport planners predict that the Tokyo to Osaka line will cost 91 billion dollars. The high cost means that Maglev technology probably won't replace other forms of transport in the near future. However, the technology is still in development and somebody might find a cheaper and simpler way to build the tracks. And then, who knows? In the future, some of us might fly to work by train.

DỊCH BÀI:

Đã một thời gian dài các nhà khoa học mơ về việc xây dựng một “tàu hỏa bay” có thể lơ lửng giữa không trung phía trên đường ray. Với công nghệ Maglev, giấc mơ của họ giờ đây đã thành sự thật. Tàu Maglev không có bánh xe. Thay vào đó, các nam châm cực mạnh nhấc chúng lên không trung và đẩy chúng về phía trước, với tốc độ lên đến 500 km/giờ.

Bên cạnh tốc độ, Maglev có vô vàn những ưu điểm so với những hệ thống giao thông khác. Tàu ít gây tiếng ồn hơn và hành trình êm hơn vì chúng không có bánh xe. Chúng cũng xanh hơn vì không sử dụng nhiên liệu và vì thế gây ô nhiễm ít hơn. Hiện trên thế giới chỉ có một hệ thống tàu Maglev tốc độ cao. Nó vận chuyển hành khách từ trung tâm thành phố Thượng Hải đến sân bay. Tuy nhiên, Nhật Bản đã bắt đầu công trình xây dựng đường ray Maglev mới và dài hơn. Đoàn tàu sẽ đi từ Tokyo đến Nagoya trong vòng 40 phút. Nhưng đừng kỳ vọng sẽ được ngồi trên đó vào chuyến đi tiếp theo đến Nhật của bạn. Phải đến năm 2027 thì nó mới đi vào hoạt động! Sau đó, vào năm 2045, tuyến sẽ mở rộng đến Osaka. 

Có một vấn đề lớn về công nghệ Maglev: việc xây dựng đường ray cực kỳ tốn kém. Các nhà hoạch định hạ tầng giao thông dự đoán rằng tuyến Tokyo đến Osaka sẽ tốn 91 tỷ đô la. Chi phí cao đồng nghĩa rằng công nghệ Maglev có thể sẽ không thay thế các hình thức vận chuyển hành khách khác trong tương lai gần. Tuy nhiên, công nghệ vẫn đang trong quá trình phát triển và một người nào đó có thể tìm ra cách rẻ hơn và đơn giản hơn để xây dựng đường ray. Ai mà biết được chứ? Trong tương lai, có thể một số người trong chúng ta sẽ bay đến chỗ làm bằng tàu lửa.

Đâu là tiêu đề phù hợp nhất cho đoạn văn?

A. Ngày tàn của tàu lửa?

B. Bay bằng tàu

C. Hệ thống tàu ở Thượng Hải

D. Thế hệ công nghệ tiếp theo

Tóm tắt:

Đoạn văn nói về ước mơ tàu bay của các nhà khoa học và thực tế về công nghệ tàu bay Maglev hiện nay.

==> Bay bằng tàu

Câu 3:

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 from 44 to 50.

For Sean O'Brien, it was just an ordinary night out with friends. He knew that people sometimes mocked him for being overweight, and he was usually able to shrug it off. But this time, as well as laughing at him in person, someone decided to publicly fat-shame him by posting a video of him dancing online, with a hurtful comment. Sean was completely unaware of it, but the post about him was shared widely, and it prompted a wave of abuse from immature Internet trolls.

However, as well as the cyberbullies, other people were watching. A group of women in California, who were campaigning to encourage people to have a positive body image whatever their size, decided to take action. They put out a message on Twitter, inviting Sean on an all-expenses- paid trip from London to Los Angeles, to meet and dance with them. When Sean's friends first told him about the search for 'dancing man', he figured it was a bit of nonsense which would soon blow over, and decided not to bother doing anything about it.

But the movement got bigger and bigger. Sean rethought his decision, made contact, and the women - all 1,700 of them - started raising money to throw him an extra-special party in LA. He went to the party in California. Sean had assumed that just a few people would turn up, but he realised his mistake as soon as he saw over 1,000 people queuing to get into the nightclub! Sean danced all night and the story of how he and the women's group in California took a stance against cyberbullying was reported around the world. As a result of the event, some of the women set up Dance Free Movement, an online forum where anyone who felt they had been bullied or victimised could receive support. The 'dancing man' himself has become a fundraiser for several anti-bullying charities.

Sean commented in an interview at the time that he was amazed that something which started out so badly, had become such a positive movement. He said that he had actually never really thought about the people who posted the original images, concluding that they must have their own insecurities, to put the spotlight on someone else so maliciously. Sean certainly had the last laugh. We are often told that the best idea is not to give bullies any attention, but it may be that the best way to deal with cyberbullying is to act as these women did and be brave enough to make it clear that we are uncomfortable with this kind of behaviour, that we disagree with what is being said and that bullying is completely unacceptable.
