答案　D

解析　细节理解题。由文章倒数第二段第一句和第二句可知，这种tiger­striped pit viper是一种新的蛇类。因为文中有明确的提示“the snake’s fangs”及“We caught the snake and the gecko...”，而the gecko的介绍在后面出现了。

B

Comfort zone is the mental place surrounded by borders in our mind where we feel secure.Even though this comfort area and its boundaries are just a state of mind that has nothing to do with reality，it plays a huge role in the progress of our development.Since the comfort zone is limited，there is not much benefit for you inside your comfort zone.Nothing new will happen until you open yourself and leave your comfort zone.

As long as you are still having the same beliefs，you cannot grow and you cannot expect new things in your life.When you change your beliefs，you will change your thoughts，feelings and actions，and only then you  can expand and grow in all aspects of your life.

Even though your background may be affecting your present situation，what really matters is not where you were born，your skin color，race，age，gender，religion，government，or even the poor environment in which you have been living for so many years，but what really matters and makes a big difference in your life is your attitude，to understand your comfort zone，how you limit yourself within it，who you are，why you behave the way you do it，and mainly where you are going.

Sadly many people don’t go anywhere because they stay within their comfort zone.They accept defeat after defeat before even trying or knowing how capable or valuable they really are.These circumstances are not the cause of our actual situation but the conformism (因循守旧) and the poverty of our thoughts and therefore the weakness of our broken spirit.Leave your past behind;constantly transcend (超越) your comfort zone!Your past within this comfort zone is nothing but a wasted load that you don’t need to carry at all.

Take constant action as many times as it is  required and never，never quit.As Napoleon Hill said，“A quitter never wins and a winner never quits.Defeat is never a failure;no circumstance ever is failure until it is accepted by the individual as a failure.”Nothing is impossible for an optimist attitude;everything is possible when we start blindly trusting ourselves，when we have a burning desire to succeed and a blind determination to make our dreams come true;everything is possible when we don’t take a no for an answer.

6. What is comfort zone according to the passage?

A.A place in our realistic life where we obtain comfort.

B.A mental place in our mind where we stick to our beliefs.

C.A limited place in our mind where we feel safe.

D.A secret place in our mind where we communicate with ourselves.

答案　C

解析　细节理解题。由文章第一段第一句可知，“安逸区”是我们心中被很多边界所环绕的一个特殊区域，在这其中我们感到安逸，但它是我们成长的藩篱。

7. The author believes staying in our comfort zone can________.

A.prevent us from being aware of the reality

B.protect us from the cruel reality

C.push our development in life

D.stop us making progress in life

答案　D

解析　细节理解题。文章第一段最后说明，待在我们心灵的“安逸区”是没有好处的，会阻止我们进步。

8. Napoleon Hill is quoted in the last paragraph to show that________.

A.one should not quit in order to succeed

B.a successful person can’t leave his comfort zone

C.there is a great difference between defeat and failure

D.it is important to take constant actions

答案　A

解析　推理判断题。文章最后一段中第一句是本段的主题句。下面引用名人名言也是为了说明这个主题：要成功，就不能退缩。

9. What is not necessary for us to  succeed?

A.A blind determination.

B.An optimistic attitude.

C.The poor environment in which we live.

D.Refusing to take a no for an answer.

答案　C

解析　细节理解题。由文章最后一段可知，A、B、D三项都是成功所需要的;而从文章第三段可知，“贫困的环境”也无碍于成功，但并非是成功的必要条件，故选C项。

10.The writing style of this passage can   be described as________.

A.defensive       B.persuasive

C.subjective       D.supportive

答案　B

解析　推理判断题。分析全文，把握作者态度可知，作者极力说服、劝告我们走出心灵的“安逸区”，因此B项persuasive“劝导的”最能说明文章的写作风格。defensive辩护的;subjective主观的;supportive支持的。
