| After Man has dreamed about flying for
a long time. Michael Moshier is a dreamer. He invented the Solo Trek. The Solo Trek had a 120 horsepower engine with twin fans. Only one person flies. As you fly above the roofs, you lean a little forward. You can see everything under you. You are flying like Superman. Michael Moshier looked at the jet belt and the rocket belt that was developed 20-30 years ago. Nothing ever came from them. People still can’t fly. Inventors have tried to make it easy for people to fly. Paul Moller has been working on his flying car for 30 years. He now says it is ready for tests. It would take off and land vertically, go 600 miles an hour, and deliver 20 miles to the gallon. A computer would do the actual flying. He says it could be sold next year for about a million dollars. NASA is working wi A. a solar powered engine B. engine-powered twin fans C. large flapping wings D. rotating blades [填空题]The old man has been dead for one year.

A. Yes, he has. B. No, he hasn’t. C. Yes, he hasn’t. [单项选择]Throughout all ages man has always carved colossal (巨大的) figures out of stone. This can be seen in the ancient ruins of Egypt, Persia and Babylon. In modern times America has also taken up the same challenge and has carved huge sculptures into her mountains.
On the East Coast of America not far from Atlanta, Georgia stands Stone Mountain, the largest mass of exposed granite (花岗石) in the world. Carved into the side of this mountain are three tremendous equestrian figures. They are sculptures of Jefferson Davis, Robert E. Lee and "Stonewall Jackson." It is a memorial to the Confederacy. The colossal figure of Lee alone measures 138 feet from the top of his head to the tip of his horse’s hoof. To see these stone sculptures on the side of a mountain is most impressive and inspiring. It was commissioned in 1916 and was begun by Gutzon Borglum, the sculptor of Mt. Rushmore, but was not completed until 1969 by Walter K. Hancock. In South Dakota, a western state., is located ano A. All nations have carved colossal figures on the stone. B. Only in Egypt, Persia and Babylon people can carve colossal figures. C. There are also some great sculptures in America. D. America is a challenge to other counties. [单项选择]Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed wood- lands into farmland, and make lakes and reservoirs out of rivers for irrigation purposes or hydroelectric (水力发电的)power. Man has also modified the face of the earth by draining marshes(沼泽) and cutting through mountains to build roads and railways.
However, man’s changes to the physical environment haven’t always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles; smoke from factories pollutes the air of industrialized areas and the surrounding areas of countryside. The air in cities is becoming increasingly unhealthy. The pollution of water is equally harmful. In the sea, pollution from oil is increasing and is killing enormous numbers of A. altering the physical features of the earth B. modifying the face of the earth C. bettering his way of life D. improving his surroundings 我来回答: 提交
