     It was time for Mr. Rocco to shut up shop when I hurried into the florist’s. “Now, what is it that you want?” Mr. Rocco turned to me. “I want the most beautiful flower you have.” I replied, “And just how much do you have to pay for this most beautiful flower?” I held out a wet hand showing a quarter and dime. He nodded, and then showed me a plant on the counter “I can give you this one for 35 cents.” he said，“ Aw, gee,” I protested, “it looks like a weed!” About l 8 inches high, the plant was in a small pot covered with faded red paper.“ Now trust me, boy---I promise that tomorrow morning when you get up, you will find your most beautiful flower. ”said Mr. Rocco. I knew him to be a good honest man, so I agreed to take it.
It was almost midnight when I arrived home. Mom was seriously sick and using the front bedroom. I looked in to see if she was asleep, and then quietly tiptoed in and set the plant on the table beside her bed. I wanted her to be surprised when she woke on Mother’s Day. The next morning, I dressed and hurried downstairs. The sun was shining through kitchen window as I looked into Mom’s room. She motioned for me to come in, then glanced over at the table where the plant was. Holy mackerel! There were three big yellow trumpet-shaped blooms. It was just like Mr. Rocco said---the most beautiful flower I ever saw! When I looked at Mom, she was smiling as tears streamed down her cheeks. She held out her hand for me to come near, then pulled me close and hugged till it hurt. Then, remembering her contagious condition and that she wasn’t supposed to touch me, she quickly let me go.
My dear Mom died the next night. The moment she hugged me turned out to be the most wonderful moment of my life. Not only had that beautiful plant helped show just how much I loved her, but I'd always know how much she loved me.

    China is going green. In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
   Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
     Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
25. The author writes this passage mainly to________.
A. teach people how to drive a hybrid car
B. show how to save their gasoline when driving a car
C. introduce a new kind of "green" car
D. announce plans to develop hybrid vehicles for China
26. The first sentence probably refers to ________.
A. there will be more and more green land in China
B. China has started producing environmentally friendly cars
C. China's new cars are combinations of different green models
D. China is still young and lacking experience
27. What is the most important feature of hybrid cars?
