A.sheB.heC.himD.her

【答案】D

【解析】

考查代词辨析。A. she她,人称代词的主格;B. he他,人称代词的主格;C. him他,人称代词的宾格;D. her她,人称代词的宾格。根据语境推测句意是“——杰克,,你看见你妹妹了吗?——是的,一个小时以前我在餐厅里看见过她。”由句意判断设空处的代词在句中放在动词saw 后面作宾语,所以应该使用宾格代词,结合前面的your sister为女性判断用her,故答案选D

【题目】 Do you like making paper planes? If you like origami (折纸), we're sure you enjoy making paper planes, too. All it takes is some paper and a new simple supply. And paper planes can be fun to fly around the houses or outside the yard.

No one knows for sure when the first paper plane was created. Sometimes, historians give credit to Leonardo da Vinci. However, paper folding and kite making were both popular in Asia hundreds of years ago, so it's likely that the first paper plane may have been made long, long ago.

In some Asian countries, the art of folding paper is called origami. Some people call the art of making paper planes aerogami.

Since paper planes flow (流动) through the air, they can teach scientists and engineers a lot about basic concepts of flight, engineering and aerodynamics (空气动力学) In fact, the National Aeronautics and Space Administration (NASA) (美国航天航空局) once sent a paper plane into space on a space shuttle!

If you are wondering how a paper plane would fly in outer space, you might be surprised by the answer. According to scientists, paper planes won't actually fly in outer space. Instead, paper planes would simply float in a straight line and could possibly float forever unless they hit another object!

The Wright brothers also used paper planes to test out their theories about flight before making their first flight. They built a wind tunnel and used paper planes to gain a better understanding of how their plane would operate in the wind.

So just how far can a paper plane fly? On February 28, 2012, former college quarterback Joe Ayoob set the world record for the longest paper plane flight. He threw a paper plane the entire length of a warehouse, setting the record at 226 feet, 10 inches. That broke the old record by 19 feet, 6 inches!
