Ⅲ．阅读理解

A

The Portuguese man­o­war（水母蜇），commonly called the blue bottle in Australia，is another stinging jellyfish（水母）.It is widely seen throughout the warmer seas of the world，especially in the Australian summer months in shallow，coastal waters.Besides，it is not uncommon to find thousands of Portuguese man­o­war floating in groups off the popular surfing beaches in Queensland，Australia.

Actually，the blue bottle is not a single sea animal，but consists a large colony of smaller marine organisms（有机体）.It is a large，gas­filled，bladder­like（胆状物）blue float，which can be up to 30 centimeters in length and rise above the water as much as 15 centimeters.The float has a crest which is used much as a sail to push the colony across the water when the wind blows.

Groups of polyps（珊瑚虫）are attached to the underside of the blue bladder，and very long tentacles（触手）extend from each of the polyps.Each of the tentacles has stinging cells that are capable of killing fish up to 10 centimeters long.The poison from the stinging cells causes breathing problems and muscle weakness，and it is through these actions that the blue bottle catches and kills its victims.

Although the sting from the blue bottle is not as deadly to humans as the box jellyfish，a person who comes into contact with a blue bottle will still suffer a lot.The sting can cause serious side effects including fever，shock and breathing problems.The severe pain from the sting may last about two hours，and depending upon treatment，the pain will usually disappear in seven hours.The usual，quick but effective first aid treatment for the sting from a blue bottle is to pour vinegar over the area of the sting and over the tentacles，before removing the tentacles from the skin.

36．How does the Portuguese man­o­war get its name blue­bottle?

A．from the blue ocean it lives in

B．from the sea plants it feeds on

C．from the colour and shape of its body

D．from the polyps that are attached to it

37．Compared with box jellyfish，the blue bottle ______.

A．doesn't like attacking human beings

B．prefers to live in a colder environment

C．can't be found off the beaches in Queensland

D．is not as harmful to humans as box jellyfish

38．The blue bottle catches and kills its victims because ______.

A．its victims are weaker in strength than the blue bottle

B．it can swim faster than most of its victims

C．it breathes out poisonous gases from its cells

D．the poison it gives off makes its victims unable to escape

39．If a man is stung by the blue bottle，he ______.

A．will suffer from a sharp severe pain

B．may stop breathing in seven hours

C．can only go to the hospital to get treated

D．should drink some vinegar to reduce pain

40．What is the purpose of the passage?

A．To compare blue bottle with box jellyfish.

B．To help readers learn more about the blue bottle.

C．To teach readers how deal with the blue bottle.

D．To warn people against the dangerous blue bottle.

B

Over the last six years I have learned what patience is.Growing up I did not have this virtue（优点）and it is a very important virtue to have.Now I can see that if you are patient you will almost always get what you want if you are supposed to have it.I gained patience when I lost my freedom.I knew that I would eventually get it back in time.

I was locked up in prison for a period of six years because at 19 years old I was playing with a handgun and I accidentally shot and killed my friend.The first couple of years was the hardest.I was always stressed out about everything.Time was dragging by because I was always paying attention to it.While I was locked up，Tom who I talked to helped put this virtue in me.He told me that it was possible that he would never make it home but that being patient and believing that one day he would was what had made him feel better.After a while I realized why he said a lot of things to me.Once I stopped paying attention to the days and just kept in mind that I would get freedom，it seemed that my time passed quickly.

Now I am home and can see that patience paid off for me.I now use this virtue in my daily activities.I know that sometimes life gets hard and that it will pay in the end to stay patient and not to get discouraged.So if you are having a hard time in life，be patient and it will eventually work out one way or another.

41．We can learn from the passage that the writer ______.

A．got patience in prison

B．always wants to know what patience is

C．began to teach others how to be patient

D．is a successful man now through failure

42．The writer was put in prison because he ______.

A．sold handguns

B．stole a handgun

C．played handguns with friends

D．killed his friend accidentally with a handgun

43．During the first few years when he was in prison the writer ______.

A．made a couple of good friends

B．thought time passed too slowly

C．felt his life was full of unexpected things

D．was very nervous and frightened

44．How did Tom make himself feel better?

A．By admitting his mistakes.

B．By helping others.

C．By being patient and believing he would be set free.

D．By thinking he would succeed.

45．In the writer's opinion people will get a good result at last if they ______.

A．try their best to help others

B．turn to others for help

C．keep patient and don't lose heart

D．set different goals and keep them up

Ⅳ．七选五

How to Forgive the Unforgivable

People hurt one another all the time.But what happens when you experience a hurt  that cuts you so deeply that you can see no way to ever forgive that person？Use these steps to recover your life.

•__46__

Make the decision to forgive.This may sound ridiculous.After all，if you are here reading this，you are looking for a way to forgive.But the decision is not a surface decision；it goes deeper.You must really want to forgive that person from your heart and soul.So make up your mind to really forgive.

•Perfection may exist in nature，but not within the human heart.

Realize that none of us is perfect.__47__ Learn to accept your own weaknesses，and you will begin to admit others' weaknesses.And this helps you to forgive.

•Thinking about the wrongs only hurts you more.

__48__When you think about the hurt  someone has done to you，you only increase the pain you feel.You can even create more pain.Leave the past to the past.Learn to live in the present.

•__49__

Remind yourself daily of the good you have in your life.Be grateful.Love and thanks have power that hate and vengeance（报复）cannot compete with.

•Persistence（坚持）leads to victory.

Print this “how to” out and place it on your refrigerator or bedroom door.__50__

A．Forgiveness can free you from the hurt.

B．Give thanks for the good in your life.

C．Hang up the gloves，and decide to forgive.

32. 答案：C　解析：这条鲨鱼因用力过猛而撞到了石头上。由上文可知，鲨鱼紧追佩里，佩里爬上了岸上的礁石，鲨鱼紧随其后，自然撞上了礁石。

33. 答案：B　解析：这条鲨鱼只是受了伤，所以是被其他鲨鱼活吃了。首先排除C项。alive“活着的”，在此处作伴随状语，表示被吃的时候的状态是活着的；lively“活泼的，活跃的，栩栩如生的”；friendly “友好的，友谊的”。

34. 答案：A　解析：struggled on one's feet固定搭配，“挣扎着站起来”。

35. 答案：B　解析：尽管已不再饥饿，鲨鱼仍在吃着。as though“好像，仿佛”；even though“即使，尽管”；as soon as “一……就……”；as long as“只要，在……的时候”。

Ⅲ.  36. 答案：C　解析：细节理解题。根据第二段的“It is a large，gas­ filled，bladder­like（胆状物）blue float...”可知水母蜇是一种大型的，蓝色的充满气体的胆状浮游物，由此可知blue bottle这个名字应该是来自这种海洋生物的颜色和外形。

37. 答案：D　解析：推理判断题。根据最后一段可知人有时也会受到水母蜇的攻击，因此选项A错误；根据第一段的“It is widely seen throughout the warmer seas of the world，”可知水母蜇喜欢的是温热的环境，因此选项B错误；根据第一段的“Besides，it is not uncommon to find...in groups off the popular surfing beaches in Queensland，Australia.”可知选项C错误；因此正确答案为D项，其依据在末段的“Although the sting from the blue bottle is not as deadly to humans as the box jellyfish，”可知箱水母对人类的侵害是致命的，而水母蜇不是。

38. 答案：D　解析：推理判断题。根据第三段的“The poison from the stinging cells causes breathing problems and muscle weakness，and it is through these actions that the blue bottle catches and kills its victims.”可知水母蜇的细胞中释放出的毒素会让它的猎物出现呼吸困难和肌肉无力，这样它们就无法逃脱，只能等死了。

39. 答案：A　解析：细节理解题。根据末段的“The severe pain from the sting may last about two hours，”可知虽然水母蜇不会让人致命，但是被它刺后，人会感到剧痛。

40. 答案：B　解析：主旨大意题。文章中先介绍了水母蜇的生活环境，然后由介绍了它的身体特性和如何捕捉猎物，最后一段又提到万一人被它伤着后，该如何处理，由此可知只有选项B项能包含这些内容。

41. 答案：A　解析：细节理解题。根据第一段“Over the last six years I have learned what patience is.”和“I gained patience when I lost my freedom.”可知，作者在狱中学会了耐心。

42. 答案：D　解析：细节理解题。根据第二段“I was locked up in prison for a period of six years because at 19 years old I was playing with a handgun and I accidentally shot and killed my friend.”可知，作者因为用手枪误杀朋友而入狱。

43. 答案：B　解析：细节理解题。根据第二段“The first couple of years was the hardest...Time was dragging by because I was always paying attention to it.”可知，作者认为时间过得太慢了。

44. 答案：C　解析：细节理解题。根据第二段“He told me that it was possible that he would never make it home but that being patient and believing that one day he would was what had made him feel better.”与后句“...kept in mind that I would get freedom，”可知，这个人有耐心并相信某天会被释放，这使他心情好点。

45. 答案：C　解析：细节理解题。根据末段“I know that sometimes life gets hard and that it will pay in the end to stay patient and not to get discouraged.”可知。

 Ⅳ.  答案：46～50 CGFBE

第四句：father后加上for

第五句：half后加the

Ⅵ．答案：

Dear_Mr_Principal，

I_am_a_student_of_our_school.I_am_writing_to_tell_you_something_about_our_canteen_service.

There are some problems to be solved.The most annoying one is the bad service of the workers.Moreover，it always takes us too much time to wait in queues to take our meals so there should be more serving windows.What's worse，the price of dishes is so high that we can't afford them.Besides these three points，there is not enough dishware to meet the needs of the increasing number of students.

Please help us solve the problems as quickly as possible.

Thanks for your consideration.

Yours_sincerely，

Li_Hua
