阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
A city without cars would be very strange, right? But Venice is such a city.
Venice is in the northeast of Italy. It wasn’t built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.
Even so, travel isn’t difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go. People in Venice move from place to place by boat.
Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences. One moment they walk across the Rialto Bridge, and there’s nothing special. But when they come back to the bridge an hour later, it’s underwater and everyone is wearing rain shoes.
Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years. This has made the ice of the Arctic Ocean (北冰洋) melt (融化). Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.
Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy’s biggest companies to build the MOST project, which was planned to be build under the seawater to stop the rising water. Anyway, this project is helping solve the problem.
【1】Which is the best way to travel in Venice?
A. The waterways. B. Taxis and cars.
C. 400 bridges. D. Boats and rain shoes.
【2】What doesn’t cause Venice to get lower and lower?
A. The ice of the Arctic Ocean melt.
B. Seawater is everywhere around the city.
C. People used too much underground water
D. The temperature has become higher over the years.
【3】What can we infer from the last passage?
A. Venice is sure to stop getting lower.
B. High waters won’t hit Venice any more.
C. Scientists can solve the problems easily.
D. Some possible ways help to solve the problem.
【4】What’s the best title of this passage?
A. The History of Venice
B. The MOST Project of Venice.
C. The Places of Interest of Venice
D. The Specials and Problems of Venice

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Actually, long-distance bicycle camping is one of the most pleasurable activities I have ever experienced.
I generally sleep poorly at night, but in the woods on a tour, I sleep like a baby, falling asleep with the music of insects. In the morning, I am awakened by the cheeps of birds. I eat a snack before getting up, and then I quickly pack my sleeping bag, air mattress (垫), tent, and other things and get on with my road. I'm slower in the morning, having less speed but a greater desire to stop at pleasant spots and enjoy the beautiful scenery. Traveling by bike allows me to stop anywhere, such as grasslands, lakes, woods, and scenic spots. Near lunch, I find a small grocery and buy some bread, sandwiches and fruit. Then I will find a town park or other shady spots to wait out the high mid-day sun. In the afternoon, my speeds are higher, and I spend less time on stops. In the late afternoon, I start riding more slowly, and I start thinking about where I will stop. I finally find a place in the early evening, cook a simple meal and have a rest. As it starts to get dark, I put up my tent, crawl in and fall asleep.
There are exciting times and difficult times as well. Visiting strange or famous places and accomplishing goals are always exciting to me. I meet and talk with interesting people along the way, sometimes other traveling cyclists. Appreciating beautiful views, meeting wild animals, and traveling up and down hills also. On the other hand, I may run into a rainy or hot spell(一段时间), have to repair my bike, or just find myself in a bad mood. The problems are infrequent and are easy to deal with. The pleasures remain in my mind for years.
