The unknown world's mystery
The sea is the biggest unknown part of our world. It covers seventy-one percent of the earth. There is still much to be discovered about this vast blanket of water. If the waters of the ocean could be removed, the sea floor with its wide valleys, irregular, mountains and rivers in the sea. would be an unbelievable sight.
Tourism under the deep blue sea
Tourists an now explore the world beneath the waves without ever getting wet. From tourist submarines to underwater dining, undersea tourism is making a big splash.
Tourist submarines(潜艇)
The popularity of submarine tours has grown rapidly in the last decade. Now, tourist submarines operate in more than 20 locations worldwide, including the waters around Okinawa and Taiwan' s Green Island. The submarines carry nearly 2 million tourists each year. Large windows offer passengers spectacular views as the submarines explore colorful coral reefs and sunken ships. Most one-hour tours cost about US $ 80.
Underwater dining
For a more upscale experience, tourists can enjoy fine dining under the sea.  Last summer the Hilton Maldives Resort opened the world's first underwater restaurant, Ithaa.  Diners walk down a staircase into the restaurant, which rests 35 feet beneath the waves of the Indian Ocean. Transparent walls surround the dining area, and you can treat guests to a panoramic(全景)ocean view.
But this excellent view doesn't come cheap. The tasting menu costs US $ 200 per person. Be sure to make reservations early, too. The restaurant seats only 14 people.

A proven method for effective textbook reading is the SQ3R method developed by Francis Robinson. The first is to survey (the S step) the chapter by reading the title, introduction, section headings, summary., and by studying any graphs, tables, illustrations or charts. The purpose of this step is to get an overview of the chapter so that you will know before you read what it will be about.  In the second step (the Q step), for each section you ask yourself questions such as "What do I already know about this topic?" and "What do I want to know?" In this step you also take the section heading and turn it into a question. This step gives you a purpose for reading the section. The third step (the first of the 3 R's) is to read to find the answers to your questions. Then at the end of each section, before going on to the next section, you recite ( the second of the 3 R's) the answers to the questions that formed in the question step. When you recite you should say the information you want to learn out loud in your own words. The fifth step is done after you have completed step 2, 3 and 4 for each section. You review (the last of the 3 R's) the entire chapter. The review is done much as the survey was in the first step. As you review, hold a mental conversation with yourself as you recite the information you selected as important to learn. The mental conversation could take the form of asking and answering the questions formed the headings or reading the summary, which lists the main ideas in the chapter, and trying to fill in the details for each main idea.
