C
The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.
【小题1】What can we learn about full-sun coffee production from Paragraph 4?
A.It limits the spread of new growing techniques.
B.It leads to air pollution and global warming.
C.It slows down the loss of shade trees.
D.It improves local soil conditions.

   About ten men in every hundred suffer from color-blindness in some way. Women are luckier: only about one in two hundred is affected on this matter. Perhaps, after all, it is safer to be driven by a woman!

There are different forms of color-blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green — a strange world indeed.

Color-blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in bright light and to tell the difference between colors. There are also millions of "rods", but these are used for seeing when it is near dark. They show us shapes but no color.

Some insects have favorite colors. Mosquitoes(蚊子) prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky.

With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

【小题1】What is the passage mainly about?
A.Colors and their surprising effects.
B.Women being luckier than men.
C.Danger caused by color-blindness.
D.Color-blindness.
【小题2】What can we know about the color-blind?
A.Not all of them have the same problem in recognizing colors.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.
【小题3】According to the passage, with the help of the cones, we can ______.
A.tell different shapes
B.see in weak light
C.kill mosquitoes
D.tell orange from yellow
【小题4】Which can we use to attract and kill mosquitoes?
A.Red light.
B.Yellow light.
C.Blue light.
D.Green light.

   Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

I was attending a stand­up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their heads off. The main reason why those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, but it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.
The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren't jealous of him.
In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage you from making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person's emotions, he will certainly like it a lot.
【小题1】What did the author find out after studying psychology?
A.Only good jokes make people laugh.
B.Many factors lead to people's laughing.
C.Funny things can make people laugh.
D.Laughter can make people healthy.
【小题2】Why did the audience laugh loud at the pedestrians?
A.They played a trick on the pedestrians.
B.The pedestrians behaved in a funny way.
C.They could feel the pedestrians' happiness.
D.Their emotion was approved of by the show.
【小题3】What does the underlined word “belittling” probably mean?
A.Annoy.B.Blame.
C.Look down on.D.Make up to.
【小题4】Which of the following best shows the structure of the passage?
A.B.
C.D.
