[多项选择]Space Tourism
Make your reservations now. The space tourism industry is officially open for business, and tickets are going for a mere $20 million for a one-week stay in space. Despite reluctance from National Air and Space Administration (NASA) , Russia made American businessman Dennis Tito the world’’s first space tourist. Tito flew into space aboard a Russian Soyuz rocket that arrived at the International Space Station (ISS) on April 30, 2001. The second space tourist, South African businessman Mark Shuttleworth, took off aboard the Russian Soyuz on April 25,2002, also bound for the ISS.
Lance Bass of N Sync was supposed to be the third to make the $20 million trip, but he did not join the three-man crew as they blasted off on October 30,2002, due to lack of payment. Probably the most incredible aspect of this proposed space tour was that NASA approved of it.

[单项选择]
I have just come home after viewing some astonishing works of art that were recently discovered in Church Hole cave in Nottinghamshire. They are not drawings, as one would expect, but etchings, and they depict a huge range of wild animals. The artists who created them lived around 13,000 years ago, and the images are remarkable on a variety of counts. First of all, their sheer number is staggering. There are ninety all together. Moreover, fifty-eight of them are on the ceiling. This is extremely rare in cave art, according to a leading expert, Dr. Wilbur Samson of Central Midlands University. "Wall pictures are the norm," he says. "But more importantly, the Church Hole etchings are an incredible artistic achievement. They can hold their own in comparison with the best found in continental Europe." I am not a student of the subject, so I have to take his word for it. However, you do not have to be an expert to appreciate their beauty.
