Scientists have observed that humans experience happiness from a wide range of stimuli(刺激), from traveling to an ideal destination to redecorating one’s home or from winning a game of soccer to eating a delicious meal. Simply watching a favorite television show or laughing at a funny joke can lift a depressed mood. While the happiness produced by such experiences tends to be short lived, a wide social network does promote a more long-lasting state of happiness as a lifestyle.

Surprisingly, income is not a primary factor in determining a person’s level of happiness once the basic needs of food, clothing, and shelter have been met. More important is one’s social network. Being socially active may be more effective in increasing one’s immunity(免疫力)to illness than a vaccine. Misery may love company, but so does happiness, and having close friends and family is vital to one’s overall level of happiness. Even sharing one’s home with an animal companion can make a person happier.

高二英语单项填空简单题查看答案及解析

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?

The human brain remembers negative experiences more easily than positive ones. Our brains have developed in this way because threats, like dangerous animals, have a more immediate effect on people’s survival compared to positive things like food or shelter. As a result, you clearly know what makes you unhappy, but do you know what makes you happy?

Research suggests that our level of happiness is partly shaped by the choices we make. If you’ve been chasing wealth, fame, power and some material things, you may be looking for happiness in the wrong places. Psychologists suggest that the following habits can make people happier.

People who own close relationships tend to be happier than those who do not. The number of our friends is not important. What matters is the quality of our relationships. Relationships that bring happiness usually consist of the sharing of feelings, acceptance, mutual (双方的) respect and trust.

People who exercise regularly can improve both their physical and mental well-being. Some research has shown that exercise can be as effective as some medicine in treating depression.

If we are so interested in an activity, we may lose track of time, and we can be in a state of flow. The activity could be playing the piano, surfing the Internet or playing a game… People who experience flow in their work or life tend to be happier.

People are more likely to be happy if they know what their strengths are and can use them regularly. People are especially happy when they can set goals and use their strengths to achieve them.

People, who think positively by being grateful, mindful and optimistic, are more likely to be happy. Being grateful means being thankful. Being mindful means considering, focusing on, and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

1.Human brains remember negative things more easily because negative things____ .

A. tend to affect human survival immediately

B. are much more important than other things

C. can make people live much happier

D. are easy to remember

2.According to this passage, people may find happiness in___ .

A. being famous　　 B. chasing power

3.In the last paragraph, the author tries to tell us to ____.

4.What does the passage mainly want to tell us?

A. Why people remember positive things easily.

C. What makes people happy.

D. What makes people sad.

Hearing live music is one of the most pleasurable experiences available to human beings. The music sounds great, but it sounds greater when you get to watch the musicians as they create it. No matter what kind of music you love, try listening to it live.
