Have you ever wished you could not feel pain? There are people in the world with this ability. They
do not know when they are hurting. Last year,Nature magazine published a report about six children who
have never suffered pain.The research team found the children after hearing about a boy who apparently
felt no pain. The boy stood on burning coals and stabbed his arms with knives to earn money.  He died in
a fall before the researchers could meet him.  But the team was able to find members of the boy's extended family.  They also seemed unable to feel pain.
This may lead to bad results. These children sometimes burned themselves with hot liquids or steam.
They sat on hot hearting devices.  They cut their lips with their teeth,but felt no pain.  Two of the children
bit off one-third of their
tongue. Yet they could feel pressure and tell differences between hot and cold.
Why were they unable to feel pain? Doctor Woods and his research team studied
DNA-deoxyribonucleic acid from the children. They also examined DNA from the children's parents. The team found that all had health. The researchers found that each child received a faulty version of the gene
from a parent.  The gene is called SCN9A.  It gives orders to a protein that serves as a passageway for
the chemical sodium(钠). All nerve cells have such passages.  This is how spinal cord and brain work.
Researchers discovered something important about SCN9A. They linked it to a rare condition in
which patients suffer painful burning in their feet or hands.  The problems of these patients were nearly
opposite to those of the children who felt no pain.  "In patients with the painful burning hands and feet,
SCN9A was too active. The findings may mean better medical help for pain," Doctor Woods says.
1. According to Doctor Woods,what do we know about the SCN9A in persons with no pain?
A. There is no SCN9A.
B. There is little SCN9A.
C. SCN9A was not active.
D. SCN9A was active
2. What is the purpose of Doctor Woods and his research team studying DNA from the children?
A. To find out why children don't feel pain.
B. To prove their supposition.
C. To obtain some faulty gene.
D. To locate the nerve cells.
3.  What is the main idea of the second paragraph?
A. Some bad results of the patients.
B. The cause of the disease.
C. The cure of the disease.
D. The differences between hot and cold.

日常生活类阅读

日常生活类阅读的概念：

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。

日常生活类阅读题答题技巧：

【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。
