Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably，mosquitoes can do more than cause an itchy(发痒的）wound. Some mosquitoes spread several serious diseases，including Dengue，yellow fever and malaria.
Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.
Mosquitoes need blood to survive. They are attracted to human skin and breath. They smell the carbon dioxide gas，which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.
But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects，with even smaller brains，use three senses to find a blood meal.
Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.
Then，the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr. Dickinson said，at first，the mosquitoes showed no interest in the objects at all. “What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a hit of CO2，they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点）.”
This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal，they also follow visual signals.
What do mosquitoes mainly use to find their targets?

A．Sense of smell.	B．Sense of touch.
C．Sense of sight.	D．Smart brains.

The first response of the mosquitoes to the objects in the experiment is .

A．to fly to the dark ones

B．to catch and stick to them

C．to take no notice of them

D．to attach themselves to them

How can we avoid being attacked by mosquitoes according to the text ?

A．Don’t let them see us.

B．Use dark objects to stop them.

C．Make them fly back and forth for hours.

D．Attract them to objects full of carbon dioxide gas.

What can be the best title for the text?

A．How Do Mosquitoes Survive?

B．Why Do Mosquitoes Need Blood?

C．How Do Mosquitoes Choose to Bite You?

D．Why Do Mosquitoes Attack the Human Being?

Whether rich or poor, we all have problems: that unfaithful mate, that annoying colleague, that persistent(持久的) disease, and the investment that is turning into a huge loss.
How can we remain calm, positive and even elegant in the face of all these difficulties of
life?
The following suggestions may help.
It comes with the pay. I have a friend who used to complain about her dead-end job and
unreasonable boss. Sounds familiar? One day I told her, "Look at it this way. You are getting
paid for the annoyance as well as the work. It comes with the pay. "
This has become my favorite saying for work-related frustrations. "Take every day as a bo-
nus. " When we learn to treasure every moment of what we have, we begin to see life in a whole
new attitude.
It's all in the mind. Sure, the psychologists tell us it is important that we work at resol-
ving problems. But they also say if you try to resolve a problem that would not go away, it would
only compound(使更复杂) the frustration.
If you tell yourself there isn' t a problem, there won' t be one. It is all in the mind.
Stop thinking about your own problem-help others instead. A lady who is struggling a
life-threatening disease showed she coped with her illness by making herself useful, by offering
help to others in a similar situation.
She has spoken to at least five other women with breast cancer. She says that the sharing
has helped her to find fresh meaning in her own life.
Never give up on your dream. Why do we give in or give up when we meet difficulities?
ls it because we have no confidenee in our cause and no commitment (承担义务)for what we
pursue?
One strong-hearted lady was the late head of the tragic Kennedy family, Rose Kennedy.
She said this on nationwide television one week after losing yet another son to assassin's( 暗杀者) bullet--Boddy Kennedy:"And we go on our way with no regrets not looking backwards to
the past, but we shall carry on with courage. "
Not the end of the world. Do you know something else? I' ve learned that care as you
might, love as,you might, some people don't care back.
And it is not the end of the world. After all, it's not the event that makes a person, is it?
It's what we do about what happens to us.
It was said that Albert Einstein' s last request on his death bed was to be given his equa-
tions(方程式) and his unfinished statement. Einstein first picked up his equations and lament-
ed(悲叹) to his son, "if only I had more mathematics!" What a great persistent spirit!
45. All of the followings are wrong EXCEPT_____.
A. some people have many problems while some have none
B. Albert Einstein pursued his dream till the last minute of his life
C. Rose Kennedy must be a timid (缺乏自信的) woman
D. we shouldn' t love those who don' t care about us
46. The passage is intended to inform the readers_____ .
A. how to face problems                       B. how to resolve problems
C. how to hold on to your dreams              D. how to help others
47. By saying "Take every day as a bonus", the author is trying to tell us __.
A. we should get a bonus every day     B. we should treasure every day in our life
C. we should make advances every day D. we should enjoy ourselves every day

第一节：阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。                              A
Endless sea, sand and sunshine on a tiny island--everyone' s idea of heaven. Who wouldn' t want to live in such a place.?
One person who certainly does is Ben Southall, from the UK. The 34-year-old was one of more　than 34,000 people who applied for the post of "caretaker" on Hamilton Island, Australia, which　the local government called "the best job in the world". The position starts in July and runs for six months. The salary is 150,000 Australian dollars(780,639 yuan).
Why Southall? Well, first let's take a look at the criteria(标准) for the job: "We're looking for applicants who like to have adventures, have a great love of the outdoors and have good commu-nication skills. "
On his application video, Southall expressed a love of adventure and included photographs of himself riding an ostrich(鸵鸟 ), running a marathon, diving, and kissing a giraffe. "From the time he was announced in the Top 50, and then the Top 16, Southall did a great job by showing true ex-citement about Queensland," Tourism Minister Peter Lawlor said in a statement.
"His ideas for how he will make the role his own.., as well as his ability to rise to a challenge impressed the judges and helped him to win his place in the top job," Lawlor said.
Southall was born in Coventry, UK and used his parents' home as a base for his adventures. He had an old Land Rover that he used for a charity-fund-raising trek(跋涉) across Africa which in-volved joining in five marathons( a 42.16 km race) and climbing five mountains.
"It was sometimes hard work to make him get his head down and do his work because he always wanted to be outside," his mother said about his early years.
"He wanted to go surfing in South Africa, so he got a job house-sitting to pay for it. We regu-larly ask him when he is going to get a proper job, but he is confident and has a strong set of friends and is a great social animal. Now he has got the perfect job for his skills," said his father.
So, you see? No matter what type of person you are, there's always the possibility of getting a dream job. How' s that? Just read the job descriptions carefully and think about how your skills and qualities fit with the ones needed for the job. That' s what Southall did to get his job.
41. The post of "caretaker" on Hamilton Island is said-to be the best job in the world mainly because of_____
A. a beautiful landscape                          B. a short working time
C. great pay for a fun job                          D. very good weather
42. According to Lawlor, what wasn' t the reason that helped Southall win the job?
A. His outstanding application video
B. His passion for the job and ability to face up to challenges
C. His great love of adventures
D. His true excitement about the Austrilian lifestyle
43. Which of the following statements about Southall is true?
A. He did a poor job in school when he was young.

D
There are three separate sources of danger in supplying energy by nuclear power (原子能)
First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak(泄漏) or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster(灾难) is extremely high.
71. Which of the following is FALSE?
A. It is possible that a leak or an explosion occurs at a power station.
B. It is unusual for radioactive materials to be transported across land.
C. The containers are likely to be broken by an earthquake.
D. Nuclear wastes remain dangerous in most cases for many years.
72. The author thinks that the ways to store nuclear wastes are ＿＿＿ .
A. easy      B. impossible        C. reasonable      D. ineffective
73. What do we learn from the last paragraph?
A. The power station is a safe place.
B. The dangers of nuclear energy can be prevented.
C. The general public are strongly against the nuclear program.
D. By itself, none of the three dangers is very likely to cause much worry.
74. What is this passage about?
A.Uses of nuclear power.                B.Dangers from nuclear power.
C.Public anger at nuclear power.          D.Accidents caused by nuclear power.
75. As for the possible dangers of nuclear power, ______.
A. none of them can be completely avoided
B. effective measures have been taken to avoid them
C. man will never be able to do anything about them
D. one is usually the cause of another

B
When I was looking at my railway timetable, I read with satisfaction that there was an express train (快车) to Westhaven. It went to the station in my hometown and the journey lasted only an hour and 17 minutes. When I got on the train, I couldn’t help noticing that a lot of villagers got on as well. At that time I was not surprised at all. I thought that there might be many people besides myself who wished to take the express train to save time. Neither was I surprised when the train stopped at Wildly, a small station a few miles along the line. Even an express train can be delayed sometimes. But when the train stopped station after station, I began to wonder. It suddenly struck me that this express was not running down the line at 90 miles an hour, but no more than 30. One hour and 17 minutes passed and we had not covered half the distance. I asked a passenger if this was Westhaven Express, but he said he had not even heard of it. Two hours later, I was talking angrily to the station master at Westhaven. When he said there was not such an express train, I asked for his copy of the timetable. There was a sign of victory in my voice when I told him that it was there in black and white. Looking at the timetable, he told me to look careful. At the bottom of the page it said, “This service has been stopped.”
