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. In 1752, Benjamin Franklin made his textbook experiment with a brass key and a silk kite that he flew in a thunderstorm to prove that lightning and electricity are the same thing. In 1920, a kite-flying championship for families and individuals was held in London. These two seemingly unrelated events underscore the fact that kites can be flown for both pleasure and scientific purposes. For example, in the 1800s weather bureaus flew kites to record temperature and humidity at certain altitudes. On one occasion, ten kites were strung together and flown at a height of four miles to lift men and carry cameras aloft. The kite’s ability to fly depends on its construction and the way that its line is attached. The familiar diamond - shaped kite flies when its covered face is aligned against the wind flow. The line attached to the nose of the kite pulls it into the wind, thus creating the necessary angle for the lift force. If the kite’s construction and the angle of the air stream are correct, the kite will encounter greater pressure against its face and lower pressure against its back. The difference in the pressure creates a lift that causes the kite to rise until it hangs level from its bridle. Its angle against the wind should be sufficiently large or small to create maximum lift to overcome both drag and gravity. The towing point to which the line is attached is important because it sets the kite’s angle relative to the air flow. Although the kite must be headed up and into the wind with a velocity of 8 to 20 miles per hour, it can maintain its position through a tail, a rudder, a keel, vents, or tassels.According to the passage, the kite flies when its nose is ______.A.pointed away from the ground B.balanced with the tailC.pointed into the wind flow D.aligned parallel to the wind flow

V. Read the following passage carefully, and then select the best option A, B, C or D to complete it.Approximately one-third of the Arctic Ocean is underlain by continental shelf, which includes a broad shelf north of Eurasia and the narrower shelves of North America and Greenland. Seaward of the continental shelves lies the Arctic Basin proper, which is subdivided (26) _______ a set of three parallel ridges and four basins (also known as deeps). These features were discovered and explored (27) _______ in the late 1940s. The Lomonosov Ridge, the major ridge, cuts the Arctic Basin (28) _______ in half, extending as a submarine bridge 1,800 km (1,100 mi) from Siberia to the northwestern tip of Greenland. Parallel to it are two shorter ridges: the Alpha Ridge on the North American side, defining the Canada and Makarov basins, (29) _______ the Arctic Mid-Ocean Ridge on the Eurasian side, defining the Nansen and Amundsen basins. The average depth of the Arctic Ocean is only 1,300 m (4,300 ft) because of the vast shallow expanses on the continental shelves.

Read the passage and write your answers to the questions given. (5 pts) Uri Geller was born in 1946. When he was only three, he was aware that he had an amazing ability. In 1969, he gave his first performance in a school. He gently rubbed a spoon with his fingers, and it began to bend. Three years later, he drove a car blindfolded through the crowded streets of Munich. Later Uri Geller appeared on television in Britain in front of a small studio audience of scientists. He bent spoons and broke metal objects simply by touching them gently with his fingers. He also drew pictures of hidden objects. After the programme, however. there were hundreds of telephone calls. People reported that spoons in their homes bent during the programme. Metal objects broke, and watches which had stopped many years before suddenly started to go again.What could he do with his amazing ability when he appeared on television in Britain?A.He could break metal objects by touching them gently with his fingers and also draw pictures of hidden objectsB.He could bend spoons and break metal objects by touching them gently with his fingers and also draw pictures of hidden objectsC.He could bend spoons and break metal objects by touching them.D.He could not bend spoons and break metal objects by touching them gently with his fingers and also draw pictures of hidden objects
