题文
阅读理解Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them
grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more
food.
In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an
important food in her part of Kenya. A virus (病毒) kept attacking the plants. It stopped the sweet
potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops.
Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a
lab in St. Louis, Missouri.
The lab mainly works on genes (基因), the chemical "computer programs" found in the cells of living
things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have
found ways to move genes from one living thing to another. That process is called genetic engineering.
Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off
the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes.
That's just the beginning, Wambugu believes. Genetically modified (转基因的) foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry.

A. tell us sweet potatoes are in danger of being attacked by a virus
B. introduce Wambugu's contribution to genetic engineering
C. introduce a new way of killing plant viruses

【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
