2 . Should we allow modern buildings to be built next to older buildings in a historic area of a city? In order to answer this question, we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons—for example, economic reasons—why they should be preserved. So, let us assume(假设)that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?

In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own hometown of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not affect its surroundings too much, it often improves the attractiveness of the area.

It is true that there are examples of new buildings which have spoilt the area they are in, but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative and do not like change.

Although we have to respect people’s feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move things forward. If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different, even though that might be the more risky choice.

Li Daiyu and her cousin Liu Qian were on a trip to Canada to visit their cousins in Halifax. They decided     1     (fly) to Vancouver first and then take the train. The thought of crossing the whole country by rail was     2     (excite) for them.

They spent two days in Vancouver. There they took a boat ride,     3     (visit) an island and saw the beautiful mountains looking out over the city.

Then they boarded the train to Lake Louise, where the blue water took     4     (they) breath away with its exceptional beauty. They spent the night and then headed north to Jasper.     5     (look) at the spectacular scenery, they both agreed it was the most awesome journey     6     they had ever taken.

From Jasper, they caught the train bound     7     Toronto. One of the train’s first stops was in Edmonton, whose daily     8     (temperature) in winter average -10℃. From Edmonton, the train headed southeast across the great Canadian Prairie.

After another day on the train, they     9     (eventual) reached Winnipeg. They travelled through the night and the next morning they reached Toronto,     10     capital of Ontario. Their trip from Vancouver to Toronto had taken four days in all.

One of the most remote destinations on the planet, Antarctica is not an easy (or affordable) endeavor. Perhaps the difficulty is part of the attraction — the seventh continent remains on the top of many travelers’ wish lists. The striking white desert, with its dramatic, snowy peaks and vibrant turquoise waters, as well its exotic wildlife, including Emperor penguins and Weddell seals, is truly a once-in-a-lifetime experience.

Hawaii is underrated. To be sure, it is a gorgeous place, with breathtaking sunrises and sunsets, and every beach seemingly prettier than the next, but its beauty goes much deeper than its preternatural appearance. Extraordinary beaches — some even boast black and green sand (Papakolea Beach and Punalu’u Beach, respectively)—have their expected appeal, but visitors who take time to venture out and away from the coast quickly discover Hawaii’s charms are everywhere.

Skiing, surfing, hiking and Northern-lights sighting. Eclectic cuisine, world-class shopping, a diverse and rich culture. This is Canada. The 13 provinces and territories that make up the world’s second-largest country by total area. It has something wonderful for every type of traveler. Nature lovers take so lace in mountains, glaciers, waterfalls and Atlantic or Pacific coastlines while sophisticated palates nosh at Michelin-starred restaurants and hole-in-the-wall mainstays alike.

Travelers don’t want to spend any more time in an airport than they have to. But Singapore’s Changi is not an ordinary airport. While the rest of the world was staying at home, Singaporean locals were paying to hang out at Changi, whether it was co-working in one of the lounges or camping alongside the world’s tallest indoor waterfall at the Changi Jewel, which opened in 2019.

7 . What do Tom Sawyer and jumping frogs have in common? Stories about both of them were created by one man: Mark Twain. Twain was four years old when his family moved to Hannibal, Missouri, located on the west bank of the Mississippi. Twain grew up there and was fascinated with life along the river—the steamboats, the giant lumber（木头）rafts, and the people who worked on them.

The Celebrated Jumping Frog of Calaveras County is one of Twain's best loved short stories, and The Adventures of Tom Sawyer is one of his most famous novels. Both these works are celebrated by events held during National Tom Sawyer Days, which originated in the late 1950s and became national in the 1960s. Children enter their frogs in the jumping contest during National Tom Sawyer Days. There's also a fence painting contest to see who can paint the fastest. The idea for this contest comes from a scene in The Adventures of Tom Sawyer, in which Tom has been told to paint the fence in front of the house he lives in. It's a beautiful day, and he would rather be doing anything else. As his friends walk by, he makes them believe that it's fun to paint, and they join in the “fun”. By the end of the day, the fence has three coats of paint!

Although the story of Tom Sawyer is fiction, it's based on facts. If you go to Hannibal, you'll see the white fence, which still stands at Twain's boyhood home.
