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 43 to 50.

    Icebergs are among nature’s most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being somewhere-in faraway, frigid waters, amid thunderous noise and splashing turbulence, which in most cases no one hears or sees. They exist only a short time and then slowly waste away just a unnoticed.

    Objects of sheerest beauty, they have been called. Appearing in an andless variety of shapes they may be dazzlingly white, or they may be glassy blue, green, or purple, tinted faintly or in darker hues. They are graceful, stately, inspiring-in calm, sunlit seas.

    But they are also called frightening and dangerous, and that they are-in the night, in the fog, and in storms. Even in clear weather one is wise to stay a safe distance away from them. Most of their bulk is hidden below the water, so their underwater parts may extend out far beyond the visible top. Also, they may roll over uexpectedly, churning the waters around them.

    Icebergs are parts of glaciers that break off, drift into the water, float about awhile, and finally melt. Icebergs afloat today are made of snowflakes that have fallen over long ages of time. They embody snows that drifted down hundreds, or many thousands, or in some cases maybe a milliom years ago. The snows fell in polar regions and on cold mountains, where they melted only a little or not at all, and so collected to great depths over the years and centuries.

          As each year’s snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice. When new snow fell on top of the old, it too turned to icy grains. So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones. With time and pressure from above, the many small ice grains joined and changed to larger crystals, and eventually the deeper crystals merged into a solid mass of ice

According to the passage, icebergs are dangerous because they

A. usually melt quickly

B. can turn over very suddenly

C. may create immense snowdrifts

D. can cause unexpected avalanches

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 following questions from 1 to 5.

Dolphins are one of the most intelligent species on the planet, which makes them a very interesting animal to scientists. In their natural habitats, dolphins use various vocalization techniques. They whistle and squeak to recognize members of their pod, identify and protect their young, and call out warnings of danger. They also make clicking sounds used for echolocation to find food and obstacles in dark and murky waters.

Amazingly, the whistling sound that the bottlenose dolphin makes has been found to have a similar pattern to human language. They always make conversational sounds when they greet each other. If you listen to dolphins' squeaks and squeals, it will sound like they are having a conversation.

Dolphins usually use both sound and body language to communicate with each other. It is through gesture and body language, however, that most of their communication with humans comes. Dolphins can be trained to perform complicated tricks. This suggests they have a high level of intelligence and communication capacity. If they work for a long time with a trainer, they are able to recognize and understand human commands.

A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication. After all, dolphins are one of the most intelligent animals. Their ability to communicate is impressive and worthy of study.

What would be the most suitable title for the passage?

A. Communications in dolphins

B. Intelligent mammals in captivity

C. Dolphins' social tendencies with humans

D. Complex patterns in dolphin life

Tạm dịch: Cá heo là một trong những loài thông minh nhất hành tinh, điều đó khiến chúng trở thành một loài động vật rất thú vị đối với các nhà khoa học. Trong môi trường sống tự nhiên của chúng, cá heo sử dụng các kỹ thuật phát âm khác nhau. Chúng huýt sáo và ré lên để nhận ra các thành viên trong nhóm của mình, xác định và bảo vệ những con cá heo con, đồng thời kêu gọi cảnh báo nguy hiểm. Họ cũng tạo ra âm thanh nhấp chuột được sử dụng cho tiếng vang để tìm thức ăn và chướng ngại vật trong vùng nước tối và âm u.

Khả năng giao tiếp của chúng rất ấn tượng và đáng để nghiên cứu.

Cá heo là một trong những loài thông minh nhất hành tinh, điều đó khiến chúng trở thành một loài động vật rất thú vị đối với các nhà khoa học. Trong môi trường sống tự nhiên của chúng, cá heo sử dụng các kỹ thuật phát âm khác nhau. Chúng huýt sáo và ré lên để nhận ra các thành viên trong nhóm của mình, xác định và bảo vệ những con cá heo con, đồng thời kêu gọi cảnh báo nguy hiểm. Chúng cũng tạo ra âm thanh nhấp chuột được sử dụng cho tiếng vang để tìm thức ăn và chướng ngại vật trong vùng nước tối và âm u.

Thật đáng ngạc nhiên, âm thanh huýt sáo mà cá heo mũi chai tạo ra đã được tìm thấy có một đặc điểm tương tự như ngôn ngữ của con người. Chúng luôn tạo ra những âm thanh trò chuyện khi chào nhau. Nếu bạn lắng nghe tiếng ré và tiếng rít của cá heo, có vẻ như chúng đang có một cuộc trò chuyện.

Cá heo thường sử dụng cả âm thanh và ngôn ngữ cơ thể để giao tiếp với nhau. Nó giao tiếp thông qua cử chỉ và ngôn ngữ cơ thể, tuy nhiên, hầu hết điều đó được huấn luyện bởi con người. Cá heo có thể được huấn luyện để thực hiện các thủ thuật phức tạp. Điều này cho thấy chúng có trí thông minh và năng lực giao tiếp cao. Nếu chúng được huấn luyện trong một khoảng thời gian dài với một huấn luyện viên, chúng có thể nhận ra và hiểu các mệnh lệnh của con người.

Rất nhiều hành vi giao tiếp của cá heo đã được nghiên cứu bằng cách để cá heo trong môi trường nuôi nhốt. Những nghiên cứu này đã bị chỉ trích vì một số nhà sinh học biển tin rằng cá heo sống trong bể cá hoặc trung tâm nghiên cứu không thể được coi là "bình thường". Mặc dù vậy, hầu hết đều tin rằng nghiên cứu hành vi giao tiếp của cá heo trong điều kiện nuôi nhốt là hữu ích để bắt đầu hiểu được sự phức tạp trong sự giao tiếp cá heo. Xét cho cùng, cá heo là một trong những loài động vật thông minh nhất. Khả năng giao tiếp của chúng rất ấn tượng và đáng để nghiên cứu.

Thật đáng ngạc nhiên, âm thanh huýt sáo mà cá heo mũi chai tạo ra đã được tìm thấy có một đặc điểm tương tự như ngôn ngữ của con người. Chúng luôn tạo ra những âm thanh trò chuyện khi chào nhau. Nếu bạn lắng nghe tiếng ré và tiếng rít của cá heo, có vẻ như chúng đang có một cuộc trò chuyện.

Cá heo thường sử dụng cả âm thanh và ngôn ngữ cơ thể để giao tiếp với nhau. Nó giao tiếp thông qua cử chỉ và ngôn ngữ cơ thể, tuy nhiên, hầu hết điều đó được huấn luyện bởi con người. Cá heo có thể được huấn luyện để thực hiện các thủ thuật phức tạp. Điều này cho thấy chúng có trí thông minh và năng lực giao tiếp cao. Nếu chúng được huấn luyện trong một khoảng thời gian dài với một huấn luyện viên, chúng có thể nhận ra và hiểu các mệnh lệnh của con người.

Rất nhiều hành vi giao tiếp của cá heo đã được nghiên cứu bằng cách để cá heo trong môi trường nuôi nhốt. Những nghiên cứu này đã bị chỉ trích vì một số nhà sinh học biển tin rằng cá heo sống trong bể cá hoặc trung tâm nghiên cứu không thể được coi là "bình thường". Mặc dù vậy, hầu hết đều tin rằng nghiên cứu hành vi giao tiếp của cá heo trong điều kiện nuôi nhốt là hữu ích để bắt đầu hiểu được sự phức tạp trong sự giao tiếp cá heo. Xét cho cùng, cá heo là một trong những loài động vật thông minh nhất. Khả năng giao tiếp của chúng rất ấn tượng và đáng để nghiên cứu.
