试题点拨---细节理解
--- the ocean researchers catch the fish, collect a small amount of mucus and then test the cells to find the genetic makeup of the fish. It can be done in about 30 minutes. In the past, the researchers would have to wait weeks or months to get test results.
The researchers have found that the technology is extremely helpful when looking at different species of Chinook salmons, because they look nearly the same. However, some of them are endangered, and the scientists need to keep track of them.
1. What do the new technology and the traditional way have in common
A. They test the fish’s mucus to tell them apart.
B. They help researchers tell different salmons apart.
C. They are carried out by researchers in the lab.
D. They aim at better protecting salmons in San Francisco.
解析: D. 根据原文内容，因为有些种类的鲑鱼处于濒危，需要跟踪和保护，所以研究者们要对捕获的鲑鱼进行检测鉴定。原来的技术需要等几周才能得到检测结果，而新技术当场30分钟内就可以检测出具体的鱼类。可以推断出它们共同之处是找到要保护的那些鲑鱼。所以D项正确。
试题点拨---续写练习
（只列出原文第一段，其余略）
I was invited to a cookout on an old friend’s farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years. A noise at a window caught my attention, so I entered it. It was a hummingbird, desperately trying to escape. She was covered in spider-webs and was barely able to move her wings. She ceased her struggle the instant I picked her up. ---
1. A few weeks later, I went to the farm again. ______________
2. I was just about to leave when the hummingbird appeared. ________
续写点拨
对于续写这个题型，我们主要从四个方面入手：
一、分析原文。注意故事的背景、发展、问题出现、问题解决。注意人物的心理变化和动作。目的是为了了解故事发展的趋势和要续写的内容。
二、分析提示两段开头的提示句和原文细节之间的因果关系，实际就是要推测两段要表达清楚哪些内容。这些内容要合情合理，不要过分的增加内容。
三、分配层次、列提纲。把要表达的内容分成有明确逻辑关系的三层，并用简单句式列出提纲。目的是在写作过程中有条理，控制好内容和词数。
四、扩写提纲。每层用两三个长短句子，每段大约八九行。卷面要整洁。注意句式的连贯和词汇的丰富。
一、 分析原文
When going to a farm, I found a hummingbird trapped and rescued her.
The birds hovered and looked into my eyes, then flying away.
When I left the farm, the bird came to see me again.
二、推测因果，明白各段应该表达的内容
Why I went to the farm again
Recalling the last experience, what should I think about the milking house and the bird
Did they talk about the bird, or did they expect the bird
What feelings in my heart when I saw the bird again
Did the bird act like the last time
love nature, cherish the emotion
三、分配层次
1. To send some objects, partly for the expectation to see the bird again.
2. I specially went to make sure the milk house window was repaired and looked out for the bird
3. We talked about the bird and joked before the time I had to leave.
4. We were all amazed and I was relieved and proud
5. The bird hovered and looked into my eyes.
6. The emotion of old friends meeting again impressed me and I enjoy the relation between nature and man.
1. A few weeks later, I went to the farm again. This time I offered to send some hardware to the farm, but inside, I still held the hope to see the bird again. The image of the tiny bird hovering in front of me would not fade in my mind. What became of her When I drove passed the milking house, I specially examined the mended window. Now the possibility of her entry and being trapped again was gone. I felt satisfied. Meeting my friends on the farm, our talk soon turned to the bird. They joked that, maybe the birds would come to see me again, which made my wish to see her even stronger. After a long talk, the bird was still unseen. In low spirits, I had to leave now.
2. I was just about to leave when the hummingbird appeared. I was so thrilled and proud that she really remembered me and came to meet me. All the people present wowed amazedly and fascinated by the bird’s reappearance. I believed she recognized me. She hovered in front of me and looked into my eyes. I thought I found the devotion and affection in her big eyes. I was even moved by the tiny creature. Like old friends meeting again, the emotion excited me and I enjoyed the relation between us. The bird flew away and took my heart with her around the fragrant nature. I found myself appreciating nature more.
