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.
The passage is about______________.
A.water sports around the world        
B.surfing
C.tourist activities in Hawaii 
D.water sports in Hawaii

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 35 to 42.
Public holidays in the United Kingdom, commonly referred to as bank holidays, are days where most businesses and non – essential services are closed although an increasing number of retail businesses (especially the larger ones) do open on some of the public holidays. There are restrictions on trading on Sundays and Christmas Day. Four public holidays are common to all countries of the United Kingdom. These are: New Year's Day, the first Monday in May, Christmas Day, and Boxing Day. Some banks open on some bank holidays. In Scotland, while New Year's Day and Christmas Day are national holidays, other bank holidays are not necessarily public holidays, since the Scots instead observe traditional local customs and practice for their public holidays. In Northern Ireland, once again, bank holidays other than New Year's Day and Christmas Day are not necessarily public holidays. Good Friday and Christmas Day are common law holidays, except in Scotland, where they are bank holidays. In Scotland the holiday on 1 January (or 2 January if 1 January is Sunday) is statutory, and 25 December is also a statutory holiday (or 26 December if Christmas Day falls on a Sunday). Boxing Day is a holiday traditionally celebrated the day following Christmas Day, when servants and tradesmen would receive gifts, known as a "Christmas box", from their bosses or employers.  Today, Boxing Day is the bank holiday that generally takes place on 26 December. And 28 December only is given if Boxing Day is Saturday.
Like Denmark, the United Kingdom has no national day holiday marked or celebrated for its formal founding date. Increasingly, there are calls for public holidays on the patron saints' days in England, Scotland and Wales. An online petition sent to the Prime Minister received 11,000 signatures for a public holiday in Wales on St. David's Day; the Scottish Parliament has passed a bill creating a public holiday on St. Andrew's Day although it must be taken in place of another public holiday; campaigners in England are calling for a bank holiday on St. George's Day; and in Cornwall, there are calls for a public holiday on St. Piran's Day.
The word “their” in paragraph 1 refers to ______.
A.traditions’
B.the Scots’    
C.holidays’         
D.the UK’s
