B About twenty of us had been fortunate enough to receive invitations to a filmstudio(影棚 ) to take part in a crowdscene． Although our “act” would last only for a short time, we could see quite a number of interesting things． We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big moviecamera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in “snow”. Two more fans were turned on, and a “strong wind” blew through the trees. The picture looked so real that it made us feel cold． The next scene was a plete contrast(對比 ). The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen. An actor and actress stood in front of the scene so that they looked as if they were at the water’s edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio! Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film “stars”! 45. Who is the author? cameraman B. A film director C. A crowdscene actor D. A workman for scene setting 46. What made the author feel cold? A. The heavy snowfall B. The manmade scene C. The low temperature D. The film being shown 47. What would happen in the “three minutes” mentioned in the last paragraph? new scene would be filmed B. More stars would act in the film C. The author would leave the studio D. The next scene would be prepared C At home, ordering food from a menu is a normal, everyday routine. I don’t even give it a second thought. In China, it’s a whole other story! Here, ordering is a fun game of trial and error, and the adventure begins before the food is even served! Many restaurants in central Beijing advertise “English language menus”, but the translations can just add to the confusion. Although acpanying pictures can be a helpful relief, the translations often make the whole experience even more amusing. During my first few weeks in China I tried some delicious dishes with strange names. As an experiment, my friends and I would order things like “students addicted to chicken gristle (軟骨 )” and “red burned lion head”. It was always fun to see what landed on our table. Eventually we learned that “l(fā)ion head” was actually pork, and “students” are “addicted” to diced (切 碎的 ) chicken with green pepper. Recently, I came across a busy restaurant down a narrow side street in a Beijing hutong. It was lunchtime and the small room was packed with people sitting on small stools (凳子 ) eating noodles. I was hungry and cold, and the steaming bowls looked irresistible! I sat myself down and called out for a “caidan!” In response, the waitress pointed to a wall at the back of the restaurant. The wall was full of Chinese characters describing numerous dishes. There was only one sentence in English: “crossing over the bridge noodles”. I had never heard of the dish and had no idea what it would taste like. I took a gamble and ordered one bowl of “crossing over the bridge noodles”. A few minutes later the waitress carried over a heavy bowl full of broth (肉湯 ) and I quickly dug in. It was the best bowl of noodles I had ever tasted! I have been back again and again and each time I point at the one English sentence – “crossing over the bridge noodles”. I always enter a restaurant in China feeling excited and a little nervous. Who knows what the next ordering adventure will reveal? 48. How does the writer find the Englishlanguage menus in many of Beijing’s restaurants? A. Confusing but amusing. B. Easy to understand. C.
