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.

1.What do mosquitoes mainly use to find their targets?

A. Sense of smell. B. Sense of touch.

C. Sense of sight. D. Smart brains.

2.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

3.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.

4.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?

I was with a group of businessmen, and we were dealing with a question—What is a good person?

At a certain point during the discussion, one of the students—a young man of about 30—described an event that happened at Christmas. He and his five-year-old son were decorating the Christmas tree, and a little boy came to the front door begging. If you ever visit Mexico, you will see that the people there take begging as nothing to get upset about and nothing to get embarrassed by.

So, this little boy came to the door, a boy about the same age as my student’s son. The father and the son went to the front door, and the father went back with his five-year-old son and said to him, “Give him one of your toys.” At the words, the little boy quickly picked up one toy, and his father said to him, “No, no－give him your favorite toy.”

And the little boy, like a little tiger, said, “No way!” He cried; he refused. But the father, like a big tiger in a way, insisted gently, “No, you must give him one of your favorite toys.”

And finally the boy, with his head down, picked up a toy he had just gotten. The father waited in the living room, and the boy walked to the front door with the toy in his hand. The father waited and waited.

What do you think happened?

After a couple of minutes, his son came running back into the living room, his face lighted up. “Daddy,” he said, “can I do that again?”

I think I have got the answer to the question.

1.From the passage, we can learn that in Mexico ________.

A. begging is looked down upon

B. begging is considered as a normal part of life

D. few people are living a poor life

2. The sentence “Daddy, can I do that again?” showed that the boy ________.

A. got pleasure by helping the little beggar

B. wanted to please his father

C. began to like the little beggar

D. wanted to be the little beggar’s friend

3.According to the writer, “being a good person” means ________.

A. having the courage to correct his/her mistakes

B. being friendly to beggars

C. being ready to give

D. being able to teach children to tell right from wrong

Most parents are focused on their children’s grade on the exams, with little attention ______ to their mental health.

My mom has eyes in the back of her head．She also taught me from an early age to be suspicious of strange men, especially when they give you presents．One day, a “nice man” bearing flowers managed to steal 20 euros from her purse, while she was holding it in her hands．“He said he was collecting for a church charity so I pulled out a euro,” she explains, “He said ‘no, no, that’s too much’ and offered to look in my purse to find a smaller coin．He must have slid out that 20 euro note at the same time．I did not even notice until an hour later．I felt so stupid.”

According to neuroscientists, the key requirement for a successful pickpocket is not having nifty (熟练的) fingers, it’s having a working knowledge of the loopholes (漏洞) in our brain．The most important of these loopholes is the fact that our brains are not set up to multi-task．Most of the time that is a good thing — it allows us to filter (过滤) out all but the most important features of the world around us．But a good trickster can use it to against you．This kind of trick involves capturing all of somebody’s attention with other movements．Street pickpockets often use this effect to their advantage by manufacturing a situation that can not help but overload your attention system．Other strategies are more psychological．Pickpockets tend to hang out a “beware of pickpockets” signs, because the first thing people do when they read it is check they still have their valuables, helpfully giving away where they are．And in my mom’s case, the thief’s best trick was not coming across like a pickpocket．“He was a very nice guy and very confident．Not someone that would cause you to suspect,” she says．Apollo Robbins, a stage pickpocket, said smart move, like moving your hand in an arc (弧) motion rather than a straight line, is another popular strategy employed by tricksters．

阅读下面的短文，请根据短文后的要求答题。

Rock climbing requires not only physical strength, but also complete mental concentration. So it is not an easy sport. But this may not be true for 20-year-old Sasha diGuilian. This fearless girl who has been dominating the sport ever since she entered this field is just getting warmed up.

The youngster who is also studying for a creative writing degree at Columbia University says that she began climbing even before she could walk. As a baby, she constantly escaped from her bed and led her friends to the nearest rocks or hills. Then at the age of seven she attended brother’s birthday party at a local rock climbing gym and found her gift for it.

Soon after, she joined the local center in her hometown of Alexandria, Virginia and began climbing— first once a week, then twice and soon, almost every day. At the age of nine, she won her first climbing competition by participating in an event that she hadn’t even been aware of, until she went to the gym for her normal climbing routine. Her competitive nature and love for the sport immediately reached the peak and she began training seriously, but this time outside the gym—climbing real mountains.

As a youngster, she dominated the Junior Continental Championships from 2004 to 2010. Then she went on to catch the Pan American Championship and the US National Championship as soon as she was old enough. And in 2011, at just 18 years old, she was crowned(加冕)Female Overall World Champion in Arco, Italy at her first attempt.

Sasha diGuilian is also the youngest woman who has completed the 5.14d graded climb in which climbers must climb rocks that are vertical. The 5.14d graded climb is regarded as the most difficult climb and it is something that even the most experienced climbers are a little afraid to take on, because a small slip could result in a severe injury or even death.

1.What does the underlined word “dominating” (Paragraph 1) mean?(1 word)

2.Where and when did Sasha diGuilian find she had the talent for rock climbing? (No more than 12 words)

3.What made Sasha diGuilian begin training seriously to climb real mountains? (No more than 10 words)

4.Why is the 5.14d graded climb considered the most difficult climb? (No more than 7 words)

5. Please explain how you are inspired by Sasha diGuilian.(No more than25 words)
