Ⅰ.阅读理解

A

When I was a boy，we lived 4 miles outside of town.We lived next to the forest and I would spend hours every day playing in it with the oak (橡树) and maple trees as my companions.I would climb up their limbs，sit in their shade，and feel their peace.

That is why it was so hard for me when I found myself to be a lumberjack as a young man.It wasn't just the back breaking work，the long hours，and the low pay.It was also seeing day after day beautiful trees that had grown for half a century being sawed(锯) up and cut into flooring.Still，I couldn't help but think that they looked a lot more lovely as living trees reaching up to Heaven than as dead flooring lying under my feet.

One afternoon after a long day's work，I was feeling particularly down and depressed.I decided to take a walk in the woods like I had as a boy in hopes of lifting my spirits and calming my soul.As I walked along with my aching back and tired body，I longed for those happy childhood days.I dropped my head frustratedly and looked down at the dirt.That is when I saw it：a single，red oak acorn (橡子) that had somehow survived the hungry deer and squirrels all winter long.Then I remembered something I'd read once：“Eventually an acorn becomes a forest！” I smiled，bent down，dug up a handful of dirt，and planted that little acorn，feeling peace and joy warming my heart.Then I walked back home happy once again to be a part of the green earth.

In this life we all start out as an acorn，but whether we become a forest or not is up to us.It we have this glorious life here to grow，learn，laugh，love，share，smile，and help others to do the same.Embrace this gift of life.Use it every day to stretch your soul towards Heaven and create a mighty forest of love.

B

Please don't feel singled out，special，or view yourself as a chosen one.She bites everyone.This is just the nature of the beast.There is absolutely no truth about the persistent myths that mosquitoes fancy females over males，that they prefer blondes and redheads over those with darker hair，or that the darker or rougher your skin，the safer you are from her bite.It is true，however，that she does play favorites and feasts on some more than others.

Blood type O seems to be the choice over types A and B or AB.People with blood type O get bitten twice as often as those with type A，with type B falling somewhere in between.

Those who have higher natural levels of certain chemicals in their skin，particularly lactic acid(乳酸)，also seem to be more attractive.From these elements，she can analyze which blood type you are.These are the same chemicals that determine an individual's level of skin bacteria and unique body smell.

Mosquitoes are also attracted by perfumes，soaps，and other applied fragrances.While this may seem unfair to many of you，she also has a desire for beer drinkers.

 Wearing bright colors is also not a wise choice，since she hunts by both sight and smell，the latter depending chiefly on the amount of carbon dioxide sent out by the potential target.So she can smell carbon dioxide from over 200 feet away.When you exercise，for example，you emit more carbon dioxide through both breath and output.You also sweat，releasing those appetizing chemicals，primarily lactic acid，that invites the mosquito's attention.

Lastly，your body temperature rises，which is an easily identifiable heat signature.On average，pregnant women suffer twice as many bites，as they have a slightly raised body temperature.

Please don't go on a shower，stop exercise or give up your beloved beer and bright T­shirts just yet.Unfortunately,85% of what makes you attractive to mosquitoes is fixed in advance in your genetic circuit board(电路板). At the end of the day，she will find blood from any exposed target of opportunity.

[语篇解读]　文章主要介绍了有些人会吸引蚊子叮咬的原因。

5．What is the purpose of the first paragraph?

A．To explain the reasons for mosquito bites.

B．To introduce a new discovery to the readers.

C．To prove that everyone suffers mosquito bites.

D．To arouse the interest of the readers in the topic.

解析：选D　推理判断题。根据第一段中的“It is true，however，that she does play favorites and feasts on some more than others.”可知，此处和上文构成转折，为下文具体介绍原因做了铺垫，目的是吸引读者对蚊子为什么会更喜欢叮咬一些人这一话题产生兴趣。故选 D 项。

6．Which element has nothing to do with mosquito bites?

A．The blood type.

B．Chemicals of bacteria.

C．Color of clothes.

D．Body temperature.

解析：选B　细节理解题。根据第二段中的“Blood type O seems to be the choice over types A and B or AB.”，第五段中的“Wearing bright colors is also not a wise choice...”和第六段中的“Lastly，your body temperature rises.”可知，血型、衣服颜色和体温的不同都会对蚊子是否叮咬有影响，只有B项未提及。故选B项。

7．What does the underlined sentence in the last paragraph mean?
