　　Life in a big city is very different from life on a farm. A city is a place, where nightlife is 1 , neon(霓虹) lights are bright, and 2 is convenient. A farm is a place where 3 are quiet and peaceful, stars at night are bright, and department stores are 4 . To me, though, the biggest 5 is the people.

　　In a city, your 6 simply lives near you, sometimes only a few meters away. You might not even know his or her 7 . In the country, your neighbor might live a few kilometers away, 8 he or she is someone you know well, someone you 9 , someone you depend on to help when 10 is needed.

　　As a child, I lived 11 , and I remember a time when a neighbor needed help. He had a fire in his corn field, and 12 was too far away. The 13 of a corn crop would have been a disaster for him. However, the people from other farms in the area saw the 14 and they all dropped what they 15 and ran to help. My father was one who went to help. Using brooms, boots, and buckets of water, they stopped the fire 16 it did too much damage, and they 17 most of the crop.

　　 18 people are sometimes a little old-fashioned and unsophisticated(质朴无华的). Sometimes they have little trusting of 19 and outsiders. They don't 20 as many people in their lives as city people do, but when they become friends with someone, they are usually friends through thick and thin(同甘共苦的).

It’s said that someone somewhere in the world is always eating sushi（寿司）. It’s the healthy snack of choice for people of all cultures .

The first sushi was actually made in China in the 2^nd century. Raw salted fish was eaten with rice. Like writing , Japanese traveled to China and took sushi back to Japan . In the middle of the 17^th century , vinegar was added to the rice to make it tastier. Since the late 20^th century raw fish on small amounts of rice has become big business .

There are different recipes (食谱) for making sushi. This one is really easy and fun. Try it !

Ingredients

200 grams of raw salmon (大马哈鱼) in one piece (other raw fish like tuna is fine)

2 cups of rice

2 cups of water

1/2 cups of vinegar

1 teaspoon of salt

2 tablespoons of sugar

Wasabi*

Japanese soy sauce (酱油)

Instructions

（1） Wash your hands before you start.

（2） Put the sugar and salt in the vinegar .Keep it in a container.

（3） Boil the rice in the 2 cups of water. This is a little less water than usual to make        the rice slightly harder .

（4） Leave the rice to cool down for 10 minutes after it’s boiled.

（5） Put the rice into a large container. Add half of the vinegar.

（6） Mix it all together with your hands. Keep mixing until it sticks together. You may need to add more of the vinegar.

（7） Let the rice cool down.

（8） Wet your hands. Make balls of rice. Each one should be about the size of a table tennis ball.

（9） Take a sharp knife and cut the salmon into thin slices. Each slice should be about 3mm thick.

（10） With the rice ball in one hand, press the cut salmon on top. Make it into a rectangular shape .

（11） Put the sushi on a plate.

（12） Put a little wasabi and soy sauce in a small dish.

（13） Serve the sushi to your friends. It goes well with green tea.

   The biggest concern people have about sushi is its freshness. Raw fish can attract bacteria, which can makes us ill or even cause death. When choosing a whole fish , the eyes should be clear. The skin should be bright and smooth and not breaking-up. When choosing cut fish , the meat ought not to give off an unpleasant smell. It should also ‘bounce back’ at you when you touch it. In other words , it should look fairly hard. Don’t buy sushi in the street. Buy from shops or supermarkets that others can recommend .

   Lots of wasabi also helps kill bacteria. It also makes your head want to explode.

  A. pour some green tea into rice  

  B. add a bit more vinegar to rice

  C. Making your own sushi   D. the development of sushi

52. We can infer from the passage that ____ .

A.      Sushi has become a multi- billion industry

B.      Making sushi is a demanding job for every one

C.      Sushi is more popular in China than in Japan

D.     You should buy sushi in shops or supermarkets only on people’s recommendation

Avalanche

Death comes quickly in the mountains. Each winter holidaymakers are caught unawares as they happily ski away from the fixed runs, little realizing that a small avalanche can send them crashing in a bone-breaking fall down the slope and leave them buried under tons of crisp white snow. There are lots of theories about how to avoid disaster when hit by an avalanche. Practice is normally less cheerful.

The snow in the Salzburg of Austria where a recent disaster took place was typical avalanche material. For several days before the incident I had skied locally. Early winter snow was wearing thin and covered with ice. On top of that new, warmer flakes were gently falling to produce a dangerous carpet. To the skier who enjoys unmarked slopes it is tempting stuff, deep new power snow on a hard base---the skiing that dreams are made of. And sometimes nightmares.

Snow falls in sections like a cake. Different sections have different densities because of the temperatures at the time of the fall and in the weeks afterwards. Problems come when any particular section is too thick and not sticking to the section beneath. The snow of the past few weeks had been falling in rather higher temperatures than those of December and early January. The result of these conditions is that even a slight increase in the temperatures sends a thin stream of water between the new snow and the old. Then the new snow simply slides off the mountain.

Such slides are not unexpected. Local citizens know the slopes which tend to avalanche and the weather in which such slides are likely. Traps are set to catch the snow or prevent it slipping; bombs are placed and exploded from time to time to set off small avalanches before a big one has time to build up; and above all, skiers are warned not to ski in danger areas.

In spite of this, avalanches happen in unexpected areas and, of course, skier ignore the warnings. The one comfort to recreational skiers, however, is that avalanche incidents on the marked ski slopes are quite rare. No ski resort wants the image of being a death trap.

1．Each winter holiday makers in the mountains come face to face with death because       .

       A．they fail to realize how dangerous avalanches can be

       B．they are not expert enough at skiing on the fixed runs

       C．they are trying to avoid areas where avalanches happen

       D．they ski great distances down the mountain side

2．It would appear from the text that avalanches are brought about because            .

       A．a particular section of snow is not thick enough

       B．there is a slight fall in the temperature

       C．heavy snowfalls turn into rain

       D．the ice between different sections of snow melts

3．In areas where avalanches are known to happen            .

       A．local residents stay indoors when the weather is bad

       B．measures are taken to prevent serious avalanches

       C．small avalanches can easily be prevented

       D．skiers form themselves into a wall to keep the snow in position
