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 obvi ously 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.

First lady Michelle Obama has some advice for some Tennessee High School graduates: Strike your own path in college and life and work to overcome(克服) difficulties with determination and courage.
The first lady told the 170 graduates that she spent too much of her own time in college focusing on academic achievements. While her success in college and law school led to a good job, she said, she ended up leaving to focus on public service.
“My message to all of you today is this: Do not waste a minute living someone else’s dream.” she said. “It takes a lot of real work to discover what brings you joy… and you won’t find what you love simply by checking boxes or padding your GPA(夸大成绩).”
She said the school reminded her of her own high school experience in Chicago. “My No. 1 goal was to go to a high school that would push me and challenge me.” she said. “I wanted to go somewhere that would celebrate achievement, a place where academic success wouldn’t make me a target(目标) of laughing at or bullying, but instead would be a badge of honour(荣誉的象征).” But Mrs. Obama said pitifully that not all students have the same opportunities. “Unfortunately, schools like this don’t exist for every kid,” she said. “You are lucky.”
The first lady told graduates that failure may be a part of their college lives and careers, and that how they respond to any difficulties will define them. “That’s when you find out what you’re really made of in those hard times.” she said. “But you only do that if you’re willing to put yourself in a position where you might fall.”
Overcoming difficulties has been the hallmark(特征) of many great people, she said. “There’s this guy Barack Obama… he lost his first race for Congress, and now he gets to call himself my husband.” The first lady joked: “I could spend a whole afternoon talking about his failures.”
What’s the purpose(目的) of Michelle’s visit to Tennessee High School?
| A．To give a speech to the graduates. | B．To help Obama win respect. |
| C．To welcome new students. | D．To give the graduates some advice. |

| D．most great people met with difficulties on their way to success including Obama |

Do you want to be a successful person? Would you like to know how successful people usually think and what drives them? Here I am going to tell you the key to success that successful people share.
First of all, successful people never blame someone or something outside of themselves for their failure to move ahead. They realize that their future lies in their own hands. They understand that they can’t control things in life, such as nature, the past and other people. At the same time, they are well aware that they can control their own thoughts and actions. They take responsibility for their life.
Perhaps what most separates successful people from others is that they live life “on purpose” --- they are doing what they believe they are put here to do. In their opinion, having a purpose in their life is the most important element that enables them to deal with things around them. They hold the view that when they live their life “on purpose”, their main concern is to do the job right. They live what they do. People want to do business with them because of their commitment. To live their life “on purpose”, successful people find a cause they believe in and create a business around it.
Besides, they never give up easily. Once they have set up goals in their life, they are willing to do whatever it takes to achieve their goals. To achievers always bear in mind what they don’t have forever. Rather than see this as negative or depressing, they would use the knowledge to spur themselves on and go after what they want energetically and passionately.
So keep in mind what successful people always hold to be true so that you will have a clear idea of what you should do to be successful in life.According to the passage, to be successful, ______.
| A．you should set up a realistic goal |
| B．you should know your strengths and weaknesses |
| C．you shouldn’t blame others for your failure |
| D．you shouldn’t waste time |
Which is NOT the key to success that successful people share?
| A．Taking responsibility for their life. |
| B．Never giving up easily. |
| C．Having a goal in life. |
| D．Controlling things in life. |
