知识点四：B篇阅读

【知识梳理】
完型填空最常用的四种解题法:　　
1.总体把握:要通读完形填空的短文，跳过空格快速阅读，了解全篇的主要内容。切不可把宝贵的时间浪费在个别字句推敲上。
2.弄清体裁:文章体裁通常分为四种：论述文、记叙文、说明文和应用文。中考选文以叙事性文章为主，如：幽默故事、科普知识、童话、简短新闻、名人轶事、社会热点问题等。读这类文章，要大体上了解故事所涉及的时间、地点、人物、事件及前因后果。
3.重视主题句:完形填空所用的短文一般不给标题，但短文的主题句，往往在每段文章的首句，有时也出现在文章的中间或结束处。主题句提供全篇的性质、大意等，这是深入了解全文的“窗口”，甚至能以语句为立足点，从该句的时态、语气推测全文的主要内容。
4.语境联想:利用上下文的提示，用学过的知识和已有的生活经验，扫清部分词汇理解上的障碍。

解题过程是：
1.通读全文，掌握大意。结合选项初步弄清短文写了些什么内容。
2.瞻前顾后，分析先行。在理解全文意思的基础上，结合文章内容对空缺句子作合乎逻辑的推理。必须弄清空缺词句的确切含义，空缺词句与其前后句的意义衔接必须自然、合理，不可出现意义断层或说东道西的情况，必须从空缺句的内部结构入手，从语法、词语固定搭配、词形变化等角度考虑，务必使所填的单词准确无误。
3.反复推敲，攻克难关。如果做不出来的话，可能要改变一下思路。如实词多与文章的内容直接相关，虚词多与文章的连贯性或句子结构直接相关，如果从内容上实在看不出要填哪个单词的话，应考虑是否需要填介词、连词等。
4.验证答案，修正错误，着重注意这几点：(1)文章是否顺畅；(2)所填单词是否是最佳单词；(3)所填单词是否有拼写错误。

【例题精讲】
【例1】 （2019嘉定二华）
We have always been warned of the dangers of the forest fires. They cause (75)______ to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be (76)______ for a forest?
People start some of the fires with a special reason to actually do well to the eco-system.
In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees
would stop sunlight from reaching the forest floor. Fires can get ready for some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
Some trees even need fires to grow. These trees hold their seeds inside. Heats from a fire allow the coat of the seeds to open up. Then the seeds fall to the ground and have the (77)______ to grow.
Scientist, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or (78)______ a large space of the forest. Fires can be dangerous for animals. Even when animals continue to live after forest fires, they can go hungry (79)______ their food has been damaged in the fire. Small, controlled fires mean than animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This (80)______ makes an eco-system.
So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.
75. A. illness B. difficulty C. damage D. flood
76. A. helpful B. powerful C. harmful D. awful

79. A. because B. although C. destroy D. waste
80. A. almost B. again C. never D. even
【答案】75-80: CACDAB

77. 考查名词，根据句意，种子落在地面上，得到 去成长。
78. 考查动词，根据句意，火 的地方比较少，所以不会造成很多浪费。
79. 考查连词，根据句意，前后句应该是因果关系。

Your neighbor,
Blue Buick
When I went to the garage the next morning, the Oldsmobile was gone, but there was a note on my windshield:
Dear Blue Buick,
