Giải thích:

Because: bởi vì                                             

When: khi

As long as: miễn là                                       

Although: mặc dù

(29) As long as you can use the breathing equipment and are able to successfully propel yourself underwater you may be able to dive.

Tạm dịch: Miễn là bạn có thể sử dụng thiết bị thở và có thể tự đẩy mình thành công dưới nước, bạn có thể lặn.

Dịch bài đọc:

Lặn bằng bình khí là một môn thể thao trong đó bạn bơi dưới nước trong thời gian dài bằng cách sử dụng thiết bị đặc biệt. Từ Scuba thực ra là một từ viết tắt của thiết bị thở dưới nước khép kín. Lặn bằng bình khí là một cách tuyệt vời để ngắm một số địa điểm rất đẹp: các địa điểm lặn san hô với cuộc sống biển đầy màu sắc của chúng là nổi tiếng nhất ngoài các điểm lặn khác bao gồm xác tàu đắm và hang động.

Lặn bằng bình khí cũng có thể là một môn thể thao rất thư giãn và ở nhiều nơi, nó rất thân thiện với người mới bắt đầu. Nhiều địa điểm lặn có thể tới được (dưới sự quan tâm của một người hướng dẫn) sau một cuộc đào tạo lặn ngắn. Bạn có thể học cách lặn nhanh hơn nhiều so với bạn có thể học các môn thể thao ví dụ như tuyết. Nó cũng thích hợp cho những người có một số khuyết tật về thể chất. Miễn là bạn có thể sử dụng thiết bị thở và có thể tự đẩy mình thành công dưới nước, bạn có thể lặn.

Read the following passage and mart the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 40 to 47.

If you enjoy water sports, Hawaii is the place for you. You can go swimming all year round in the warm water. You can go sport fishing from the shore or from a boat. If you like boats, you can go sailing, canoeing, or windsurfing. Or, you can also try some other water sports that are especially popular in Hawaii: surfing, snorkeling and scuba diving.

Surfing is a sport which started in Hawaii many years ago. The Hawaiians called it “he’e nalu”, which means “to slide on a wave”. If you want to try surfing, you need, first of all, to be a good swimmer. You also have to have an excellent sense of balance. You must swim out from the beach with your surfboard under your arm. When you get to where the waves begin to break, you wait for a calm moment. Then you try to stand up on the board. The wave will begin to rise under you. You must try to steer the board with your feet so you stay on top of the wave. The important thing is to keep your balance and not fall down. If you can manage this, you will have an exciting ride all the way in to the shore.

Scuba diving and snorkeling are two ways to get a close look at the beauty lying below the surface of the ocean. The waters off the Hawaiian Islands are clean, clear and warm. They contain hundreds of kinds of colorful fish. The undersea world is made even more colorful by the coral reefs of red, gold, white and light purple. Among these reefs there may be larger fish or sea turtles.

Scuba diving allows you to see the most interesting undersea sights. “Scuba” means “Self-contained Underwater Breathing Apparatus”, that is, equipment for breathing and swimming around far under water. In Hawaii, you can take special courses to learn how to scuba dive. After the courses, you can get a certificate that will allow you to dive alone. Since it can be dangerous, proper instruction and great care are always necessary when you are scuba diving.

If you are adventurous, you might try snorkeling instead of scuba diving. Less equipment is needed, just a face mask, a breathing tube (snorkel) and flippers for your feet. It only takes a few minutes to learn how to snorkel. Although you cannot dive deep into the water, you can swim with your face below the surface. Breathing through the tube, you float on the surface, and keep yourself moving with your flippers. Even from the surface like this, there will be plenty of color and beauty to see.

According to the passage, scuba diving ____. 

A. is an ancient Hawaiian water sport 

B. requires good balance

A.   Là môn thể thao dưới nước cổ đại của Hawaii

D.   Đòi hỏi sự cân bằng tốt

Less equipment is needed, just a face mask, a breathing tube (snorkel) and flippers for your feet. 

Tạm dịch:  "Scuba" có nghĩa là "Thiết bị thở nước dưới nước độc lập", tức là các thiết bị để thở và bơi xung quanh dưới nước. Tại Hawaii, bạn có thể học các khóa học đặc biệt để học cách lặn. Sau khóa học, bạn có thể có được một chứng chỉ cho phép bạn lặn một mình. Vì nó có thể nguy hiểm nên bạn phải luôn luôn cần đến sự hướng dẫn và chăm sóc tuyệt vời khi bạn lặn biển. Nếu bạn thích mạo hiểm, bạn có thể thử lặn bằng ống thở thay vì lặn bằng bình khí. Cần ít thiết bị hơn, chỉ cần một mặt nạ, một ống thở (lặn) và chân vịt cho chân của bạn.
