Question

Mark the letter a, B, C, or D on your answer sheet to indicate the sentence that is closest meaning to each of the following questions or indicate the correct answer to each of them from 1 to 8

Tsunami is a Japanese word which means harbor wave and is used as the scientific term for seismic sea wave generated by an undersea earthquake or possibly an undersea landslide or volcanic eruption. When the ocean floor is tilted or offset during an earthquake, a set of waves is created similar to the concentric waves generated by an object dropped into the wave. Most tsunamis originate along the Ring of Fire, a zone of volcanoes and seismic activity, 32.500 km long that encircles the Pacific Ocean. Since 1819, about 40 tsunami have struck the Hawaiian Islands.

A tsunami can have wave lengths, or widths, of 100 to 200 km, and may travel hundreds of kilometres across the deep ocean, reaching speeds of about 725 to 800 kilometres an hour. Upon entering shallow coastal waters, the wave, which may have been only about half a metre high out at sea, suddenly grows rapidly. When the wave reaches the shore, it may be 15 metres high or more. Tsunamis have tremendous energy because of the great volume of water affected. They are capable of obliterating coastal settlements.

Tsunami should not be confused with storm surges, which are domes of water that rise underneath hurricanes or cyclones and cause extensive coastal flooding when the storms reach land. Storm surges are particularly devastating if they occur at high tide. A cyclone and accompanying storm surge killed an estimated 500,000 people in Bangladesh in 1970. The tsunami which truck south and southeast Asia in late 2004 killed over 200 thousand people.

Which of the following is NOT true?

A. Tsunami only occurs in Asia.

B. A cyclone along with storm surge happened in Asia in 1970

C. Storm surges are domes of water rising underneath hurricanes or cyclones

D. Storm surges causes extensive coastal flooding

Answer 1

Đáp án A

Câu nào sau đây không đúng:

A. Sóng thần chỉ xảy ra ở Châu Á.

B. Một cơn lốc xoáy cùng với cơn bão đã xảy ra ở châu Á vào năm 1970.

C. Bão dâng là những vòm nước dâng cao bên dưới các cơn bão hoặc lốc xoáy.

D. Sóng dâng gây ra ngập lụt ven biển trên diện rộng.

Dẫn chứng: “Most tsunamis originate along the Ring of Fire, a zone of volcanoes and seismic activity, 32.500 km long that encircles the Pacific Ocean” – ( Phần lớn sóng thần bắt nguồn dọc theo Vành đai Lửa - khu vực hoạt động của núi lủa và địa chấn, trải dài 32.500 km bao quanh Thái Bình Dương ) => sóng thần xảy ra quanh khu vực Thái Bình Dương chứ không chỉ 1 mình Châu Á.
