Ⅰ．阅读理解

For his 86th birthday, Cheng Xiangwen enjoyed a corn­shaped cake his colleagues had prepared for him．“My birthday wish is to develop better corn varieties，”he says．After the celebration, he began another journey to Sanya, in South China's Hainan Province, where he has worked most of his life．Cheng is a scientist in agriculture and spends most of his life studying and cultivating (栽培) corn．He visits Sanya in November every year and stays there for six months to cultivate corn．

Once, when he was conducting a field survey, a female farmer said to him in tears, “You graduated from college．Could you please find a way to increase the corn output here? If the yields (产量) are higher, our children will no longer suffer from hunger．”Since then, Cheng has made developing high­yield corn varieties his life's mission．

In 1964, he came to Hainan, where it was warmer, and started his work there．He greatly shortened the cultivation period and created hybrid corn varieties for the first time．With these new varieties, farmers in Xunxian County saw their average corn output was more than 3，750 kg per hectare per year．

Despite the beautiful coastline, the environment where Cheng works used to be troubled by poverty and poor traffic．Locals once described the area as having a large number of rats, mosquitoes, and poisonous snakes．At that time, he did everything on his own．He lived in a local villager's house and he frequently went to the mountains to chop firewood to cook．His hard work, however, has paid off．Now, authorities have approved 14 new, high­yield corn varieties Cheng helped develop．

Cheng is dedicated to developing high­yield corn varieties with stronger resistance and they are easier to harvest with machines．He still goes to the fields each day and observes and records the corn plants．“Cultivating seeds is like raising kids．Only by careful parenting can you become familiar with their strengths and weaknesses and help them to grow up healthily，”he says．

Ⅱ．读后续写

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

One day, when I was a freshman in high school, I saw a kid from my class walking home from school．His name was Kyle．It looked like he was carrying all of his books．I thought to myself, “Why would anyone bring home all his books on a Friday? He must be silly．”I had quite a weekend planned, so I shook my head and went on．

As I was walking, I saw a group of kids running towards him．They ran at him, knocking all his books out of his arms and he landed in the dirt．His glasses went flying．He looked up and I saw this terrible sadness in his eyes．

My heart went out to him．So I ran to him．As he was looking for his glasses, I saw tears in his eyes．I handed him his glasses．He looked at me and said, “Thanks！”There was a big smile on his face．It was one of those smiles that showed real gratefulness．I helped him pick up his books, and asked him where he lived．It turned out he lived near me, so I asked him why I had never seen him before．He said he had gone to private school before coming to this school．

We talked all the way home and I carried his books．He turned out to be a pretty cool kid．I asked him if he wanted to play football on Saturday with me and my friends．He said yes．The more I got to know Kyle, the more I liked him．Monday morning came, and Kyle carried all his books again．I stopped him and helped him carry half the books．Over the next four years, Kyle and I became best friends．

When we were seniors, Kyle was the best student in our class．He was chosen to give a speech at the coming graduation ceremony．
