Plants need green leaves to make food. A plant needs sunlight and carbon dioxide from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins can't carry all this sugar away, so the leaves change the sugar into starch , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem and in leaves, fruits and seeds. Food is stored in roots or stems in the form of _ . A) sugar B) starch C) water and salts D) carbon dioxide

Around every Lunar New Year holiday, China becomes a country on the move. The holiday crush this year is estimated to be even heavier than before. Government officials suggest that Chinese people will take to the air, roads and railways 3.62 billion times over a 40-day period around the nation's most important holiday this year as people push their way home for family gatherings or to satisfy their new-found passion for travel. Getting tickets to all those would-be travelers is a _ challenge that tries your patience annually. And the pressure for the railway system is always the greatest. Railways are the transport of choice for low-cost long-distance travel, and that's where the ticketing system regularly falls down. Much of the criticism has focused on the railway's online purchasing system, which has been unable to keep pace with the huge demand and also failed to stop scalpers from easily getting many of the hard-to-find tickets. Railway officials believed that online sales were the fairest way to get tickets for travelers, and told reporters that the public need to be patient. While by now the railway service is far from satisfying, efforts are being made to provide online identity checks that would reduce the ticket scalping problems, and the situation is expected to get better in a few years. Meanwhile, for those traveling by car, good news is that the country's extremely expensive highway tolls will be removed for the period of the official holiday. Which of the following can best describe the author's attitude to the railway service? A) Optimistic. B) Doubtful. C) Satisfied. D) Worried.

I am not just a successful architect . I also like to play the piano. In my spare time I often turn some dry musical symbols into beautiful music. Many years ago, while I was in a university studying architecture, I worked in a workshop. During the break I found an old piano in the corner of the room. With the allowance of the boss I sat down to have a try. Following my fingers the keys danced brilliantly and at the same time beautiful music flew out and then to every part of the room. All my workmates suddenly stopped talking and made their ears ready for my music. After graduation, I began to devote myself to my profession. All my musical talent was wasted into zero. Then one evening we went to a concert at which Mr. Stevenson, one of the ordinary workers in my company, sang us some beautiful songs. His musical talents made us all surprised. We all enjoyed ourselves with his beautiful voice so much that we even thought him a professional singer. I was also reminded of my musical talent. I began to train in a training center. My teacher was strict with me. He encouraged me to train every weekend and each time he asked me to play better than the last. Now I can proudly say I am also a successful pianist because every time I played on the stage fresh flowers and warm clapping would come from my audience. So I say, my friends, don't busy yourself with your work too much. Find some time to develop your potential talent and your life will become more wonderful. What is the author's aim in writing this passage? A) He wanted to tell us that he is successful both in work and life. B) He wanted to tell us to develop our potential talent instead of busying ourselves with our work only. C) He wanted to tell us that the concert is very important to his life.

Question: Every Saturday or Sunday night my family and I go out and feed the homeless people in the city of Orlando. There are thousands of people across the United States without any food or shelter. My family and I have been doing this for several months. We all get together in the kitchen and prepare the food. Some of the meals are sandwiches, cookies and a bottle of water. Sometimes my mom prepares a steaming hot delicious meal. We then bag them all up to feed 30 or more people. I like to write special notes on the bags like "God loves you." Before my family and I get into the car we ask God for protection in a family prayer. A lot of people misunderstand homeless people. Not all homeless people are drug addicts or bad people. Some are really nice. Some of them just had bad things that happened to them. At first when my family and I went out on the street we had to earn their trust. A lot of people are unkind to them for no good reason. But now that they see us every week, they trust us. We even know some of their names. We all have to remember that these are people that have feelings. Some of them shake our hands for giving them food, and thank us. Some of them do really funny dances because they are happy. We have become really close with this man named Tony and his wife. They have all of their personal belongings in shopping carts. After meeting with them several times he has told us a lot about his life. He graduated from Harvard University and has a PHD. He used to teach French and Spanish.
