【正文】 means that they were built higher in the middle than on the edges, allowing rainwater to run off, which prevented flooding. We use the same technique in building roads today. The Romans also laid out roads over hills when necessary, setting them down in a zigzag pattern to make the road rise gradually. All Roman roads had milestones (里程碑 ), placed every thousands paces (a Roman mile). The milestones told when the road was built, who was emperor at the time, the road’ s destination, how far the traveler was from the destination, and how many miles had been traveled since the beginning of the road. This information was a great help to travelers. Because of their excellence in construction, it really is no surprise that many parts of Roman road still exist today. These roadways are one of the most impressive acplishments of the Roman Empire. 52. What does the underlined sentence in the first paragraph mean? A. The Roman Empire was very powerful. B.

It was the first time we’d been off the base on our own without our field assistant, so it had a slightly different feeling — more like a few friends going to the seaside than an Antarctic field trip! When we reached Windy Creek, we luckily caught sight of quite a few small flying seabirds, which are seldom seen there. Once on the sea ice we found that some of the more curious penguins had wandered over from the main group to e and check us out. We’ d been told that then they were nursing their chicks (剛孵出的幼雛 ) and they would be more careful and nervous than last time, but that didn’t seem to be the case. We walked across to the main group which were stretched for a couple of miles along the coast. We sat down for some sandwiches and soon found ourselves surrounded by many curious observers. Without any attackers on land, they were very brave and came within a meter of us to pose (擺姿勢 ) for photos. Before heading back, we spent a few hours on the sea ice watching the penguins and their chicks, which had grown dramatically (明顯地 ) since our last visit. It was such a nice day. 36. When did the trip most probably happen? A. On a dull Sunday. B. On a warm Sunday. C. On a summer Sunday. D. On a winter Sunday. 37.

Last time I went down there was a couple of months ago and it was a dull cold day.
