Questions 29 to 32 are based on the following passage:

　　Noting that “an air route without markings（标记） is like a highway without signs,” Phoebe F. Omlie of the National Advisory（顾问） Committee for Aeronautics（航空家） in 1935 conceived（构思） a plan to paint town names and directional indicators on the roofs of buildings throughout the United States.

　　At Eleanor Roosevelt’s suggestion, the Bureau of Air commerce hired women fliers, among them Louise Thaden and Blanche Noyes, to scout（侦察） sites and get permission for the markers from local officials and building owners. Workers then painted the signs in orange characters, seven to twelve feet high and legible（可以看得出） from 3,000 feet. The system soon became the answer to a lost pilot’s prayer with 16,000 markers-one every 15 miles on every air route in the country.

Questions 33 to 36 are based on the following passage:

. Jokes are as old as the spoken word. In every country in the world and in every age in history, people have old funny stories to make one another laugh. In the Middle Ages in Europe, the court jesters(弄臣) or fools, amused( 逗乐) rulers and their courts with jokes and tricks.

　　While we no longer have court jesters, we still have people whose job is to make us laugh. We still laugh at many of the same things that made people laugh long ago. We laugh at jokes that have surprise endings, and stories of people who simply never seem able to do anything right. Quick answers also amuse us. Here are some simple jokes that will show you what they mean.
