6 . The whale, as big as a locomotive(火车头) jumped out of the water, spinning(旋转) as though for joy, before jumping back under the waves. We watched the scene(场景) silently in astonishment, never having been so close to such a huge, fast-moving creature. It seemed almost possible to count the small shellfish on the whale’s skin.

In early December, gray whales, blue whales, and others had just started heading around the tip of Baja California, Mexico, moving as a community from the Pacific Ocean to the Sea of Cortez. It’s in that protected waterway that pregnant whales give birth to their babies. Other whale babies, born the year before, could be seen sailing behind. All whale babies get two trips like this with their mom before they’re ready to start having babies of their own and making the journey on their own.

We’re in one of several small powerboats, sent out by Scuba Caribe, which carries on such tours in Cabo San Lucas. The whales seemed to be, at times, less than 100 feet from our boat when they rushed out of the water. At other times, they would get much closer and swim beside the boat.

“What if one lands on us?” a woman next to me wondered. Fernando Del Toro, the Destination Manager of Scuba Caribe said, “We haven’t had any incident (事件) of whales jumping over our boats as we always keep our distance. We’re sure they themselves are probably careful not to crash into boats. Such an accident would probably also cause them much harm.”

“Everyone can enjoy this magical trip,” said Del Toro. “However, we do not recommend(推荐) it for kids under 5 years old,” he added.

Though conditions on the water vary, our trip was wonderful. Even when the boat sped up to catch up with the whales, there was little need to “hang on”, and some of us remained standing throughout most of the trip. Still, you may want to pack medicine for those who might get seasick while bouncing(颠簸行进) along the waves.

9 . Football is, I suppose, the most popular game in England: one has only to go to one of the important matches to see this. Rich and poor, young and old, one can see them all there, shouting and cheering for one side or the other.

One of the most surprising things about football in England to a stranger is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He has photographs of them and knows the results of a large number of matches. He will tell you who he expects will win , and his opinion is usually as valuable as that of men three or four times his age.

Most schools in England take football seriously — much more seriously than nearly all European schools, where lessons are all-important, and games are left for private arrangements. In England, it is believed that education is not only a matter of filling a boy’s mind with facts in a classroom education also means character training. One of the best ways of training character is by means of games, especially team games, where the boy has to learn to work with others for his team, instead of working selfishly for himself alone. The school therefore arranges games and matches for its pupils. Football is a good team game, it is good exercise for the body, it needs skill and a quick brain, it is popular and it is cheap. As a result, it is the school's favorite game in the winter.

10 . When we think of bicycles, we think of fun and the outdoors. Bicycles give riders the freedom to explore and enjoy the environment and its surroundings.     1    

Most people know that riding bicycles is environmentally friendly.     2     If you are riding a bike, you are helping to reduce air and noise pollution.

Bikes are becoming more and more popular across the world. In fact, they are becoming more than just a fun pastime (娱乐).     3     For many people around the world, access to markets and schools would not be accessible without a bike.

    4     Some cities, such as Paris and Barcelona, have not only built bicycle lanes but also have introduced a system of renting bikes. You can rent, or use a bicycle in one area of the city and drop it off in another area of the city. Paris now has thousands of bikes for public use, with bicycle stations located throughout the city.

Some South American cities, such as Bogota in Colombia, have a weekly car-free day.     5     On these days, the traffic-related air pollution from old buses and trucks is greatly reduced.

It seems that the bike is a force for good, providing solutions for cleaner cities without leaving a serious environmental footprint.
