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 13 to 20.

Have you ever thought about inventing something? Did you worry that your idea was too strange or

unrealistic? Well, maybe you should think again. Strange or unrealistic ideas never stopped Arthur Pedrick. Pedrick was a British inventor. Originally a government clerk, he spent his retirement in the 1960s and 1970s developing new and unusual ideas. Some of these ideas contradicted basic physics, but that didn’t stop Pedrick. One of his strangest ideas was a plan to connect large tubes from the continent of Australia all the way to Antarctica, a distance of 10,000 km! These tubes would carry giant ice balls from Antarctica to Australia. This ice would then melt in the Australian desert, and the water would be used in irrigation. Another of Pedrick’s inventions was a radio-controlled golf ball. A golfer could change the speed and direction of the golf ball by small flaps, controlled by computer chips. Using radio waves, the golfer could also find lost golf balls. Arthur Pedrick had thousands of bizarre ideas for inventions, most of which were never built.

Though many of Pedrick’s inventions were never developed, a lot of other strange ideas were. In 1989, a company designed and sold a theft-prevention device for expensive cars. As part of this device, several tubes were attached to the bottom of a car. If someone tried to steal the car, super hot flames would come out of the tubes and burn the car thief. Some people who were not thieves, however, were seriously injured. They accidentally set off the device by walking past the car. Other strange inventions include underwear for dogs and pens with drinkable ink. The underwear keeps dogs from making a mess when they go out for a walk. Also, if you are ever thirsty during a test, a pen with drinkable ink would be very handy! If you have an idea that seems a little out in left field, don’t let that stop you from trying it. You’ll be in good company

According to the passage, how was Pedrick’s plan to bring water to Australia probably unrealistic? 

A. Tubes are not strong enough

B. Australia doesn’t need water

C. The plan was too expensive

D. Australia and Antarctica are too far away

Dịch bài đọc:

Bạn đã bao giờ nghĩ về việc phát minh ra một cái gì đó? Bạn có lo lắng rằng ý tưởng của bạn quá xa lạ hay không thực tế? Có lẽ bạn nên suy nghĩ lại. Những ý tưởng kỳ lạ hoặc không thực tế không bao giờ ngăn cản Arthur Pedrick. Pedrick là một nhà phát minh người Anh. Xuất thân là một thư ký của chính phủ, ông đã dành thời gian nghỉ hưu vào những năm 1960 và 1970 để phát triển những ý tưởng mới và khác thường. Một số trong những ý tưởng này mâu thuẫn với vật lý cơ bản, nhưng điều đó không thể ngăn cản Pedrick. Một trong những ý tưởng kỳ lạ nhất của ông là kế hoạch kết nối các ống lớn từ châu Đại Dương đến Nam Cực,

với khoảng cách 10.000 km! Những ống này sẽ mang những quả bóng băng khổng lồ từ Nam Cực đến Úc. Tảng băng này sau đó sẽ tan chảy trên sa mạc Úc và nước sẽ được sử dụng để tưới tiêu. Một phát minh khác của Pedrick là một quả bóng gôn điều khiển bằng radio. Người chơi gôn có thể thay đổi tốc độ và hướng của quả bóng gôn bằng những cú đập nhỏ, được điều khiển bởi chip máy tính. Sử dụng sóng radio, người chơi gôn cũng có thể tìm thấy những quả bóng gôn bị mất. Arthur Pedrick có hàng ngàn ý tưởng kỳ quái cho các phát minh, hầu hết trong số đó không bao giờ được chế tạo.

Mặc dù nhiều phát minh của Pedrick không bao giờ được phát triển, rất nhiều ý tưởng kỳ lạ khác đã được thực hiện. Năm 1989, một công ty đã thiết kế và bán một thiết bị chống trộm cho những chiếc xe đắt tiền. Một phần của thiết bị này là một số ống được gắn vào đáy xe. Nếu ai đó cố gắng đánh cắp chiếc xe, ngọn lửa siêu nóng sẽ thoát ra khỏi ống và đốt cháy kẻ trộm xe. Tuy nhiên, một số người không phải là kẻ trộm đã bị thương nặng. Họ vô tình kích hoạt thiết bị khi đi ngang qua xe. Những phát minh kỳ lạ khác bao gồm đồ lót cho chó và bút mực có thể uống được. Đồ lót giữ cho chó không làm xung quanh hỗn độn khi chúng đi dạo. Ngoài ra, nếu bạn thấy khát trong giờ kiểm tra, một cây bút có mực uống được sẽ rất tiện dụng! Nếu bạn có một ý tưởng có vẻ không giống với người khác, đừng để điều đó ngăn bạn thử nó. Đừng lo lắng vì cũng có những người khác giống như bạn

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 52.

A rather surprising geographical feature of Antarctica is that a huge freshwater, one of the world’s largest and deepest, lies hidden there under four kilometers of ice. Now known as Lake  Vostok, this huge body of water is located under the ice block that comprises Antarctica. The lake is able to exist in its unfrozen state beneath this block of ice because its waters are warned by geothermal heat from the earth’s core. This thick glacier above Lake Vostok actually insulates it from frigid temperatures (the lowest ever recorded on Earth) on the surface.

The lake was first discovered in the 1970s while a research team was conducting an aerial survey of the area. Radio waves from the survey equipment penetrated the ice and revealed a body of water of indeterminate size. It was not until much more recently that data collected by satellite made scientists aware of the tremendous size of the lake; satellite-borne radar detected an extremely flat region where the ice remains level because it is floating on the water of the lake.

The discovery of such a huge fresh water lake trapped under Antarctica is of interest to the scientific community because of the potential that the lake contains ancient microbes that have survived for thousands upon thousands of years, unaffected by factors such as nuclear fallout and elevated ultraviolet light that have conducting research on the lake in such a harsh climate and in the problems associated with obtaining uncontaminated sampled from the lake without actually exposing the lake to contamination. Scientists are looking for possible ways to accomplish this

It can be interfered  from  the passage that ice would not be flat if _______.

 

A. there were no lake                                  

B. the lake were not so big

C. Antarctica were not so cold

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.

By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.

Making an efficient ice box was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

According to the passage, which of the following was an obstacle to the development of the icebox?

A. Competition among the owners of refrigerated freight cars

B. The lack of a network for the distribution of ice 

C. The use of insufficient insulation 

D. Inadequate understanding of physics
