For six hours we shot through the barren(荒芜的)landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was in to the fourth, a beautiful leather notebook I’d bought in a market in Mozambique.
Southern Africa was full of stories. And visions. We were almost drunk on sensations. The roaring (咆哮)of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.
And then the other things: dogs in the streets, whole families in Soweto living in one room a kilometre from clean water.

[单项选择]Passage One From time to time, we need an expert. In such situations, the Internet has been like a gift from the gods. In the old days, authorities were near at hand for expert advice: the village seamstress on how to make a buttonhole, the blacksmith on how to take care of a horse’s hooves, or the apothecary on what to do about warts.

Real Answers.” It’s said that expert sites or knowledge networks represent the latest stage in the Internet’s evolution, a “democratization of expertise.” However, if your question is about something other than “Who invented the light bulb”, the answers are likely to be a wild potpourri of personal opinions. Top colleges and universities ar

Passage Four
At one time or another we have all stopped to think about the weather. Some days the weather is good. Some days the weather is bad. Still, there are days when the weather seems to change from hour to hour. A day that starts out fine might not stay that way. Sometimes a day that seems bad turns out better than you thought it would. There are ways of understanding the weather. One way is to study the clouds.
No two clouds are ever alike. But it is still possible to group clouds and to give them names. We can recognize the different kinds of clouds and watch them for signs of changing weather.
As a rule, the higher the clouds, the better the weather. And the lower the clouds, the worse the weather is likely to be. To predict the weather, there are three things about clouds you should look for: movement, color, and change.
Clouds can tell you if storm is on the way. For example, small feathery cirrus clouds (卷云) can become thick and
