What does fizz (气泡) taste like? In Bubbly (多泡的)drinks such as sodas, tiny bubbles give the drink a lift--- and have a distinct taste, In a new study on mice, scientists have connected that fizzy-taste feeling to the ability to taste sourness, such as that of oranges or vinegar.
Scientists first thought the taste of bubbles came from the bubbles bursting on the tongue, but now ate starting to think differently. Charles Zuker, of Columbia University, and his team studied the nervous system of mice to understand how the tongue tastes carbon dioxide, which is the gas that makes up the bubbles.
Animals, including human beings, are able to detect different tastes by using taste buds(味蕾) which pick up tastes in the mouth, and then send them to the brain. In the experiment, different groups of mice were genetically engineered to be missing one of the senses involved in taste. “Genetically engineered” means the researchers were able to turn off the switches for certain senses by changing the genes responsible for taste. The mice in one group could not taste sweet; another, sour; the third, bitter, and the fourth, salt. When the scientists gave carbon dioxide to the mice, the nervous systems of all the mice responded to the gas, except those of the mice that could not taste sour.
This shows that the taste of the bubbles must be sour, and that by turning off the ability of the mice to taste sour, the scientists also turned off their ability to taste carbon dioxide. When they studied the cells that detect sourness, the researchers found a protein attached to the cells that is important to the process of tasting carbon dioxide. When carbon dioxide comes into contact with this protein, the protein knocks off particles called protons. These protons(质子), in turn, travel to the brain, which says ,” Hey! That’s a taste!”
It may seem like a lot of work to get from a can of soda to a taste, but the science of the senses is anything but simple, “ Taste is a challenging system to study,” one researcher says.

Do you know what it means when somebody tells you that he had “a catch-22 experience”?
The phrase “catch-22” comes from a book of the same title by the American writer Joseph Heller published in 1961．Catch-22 is a book of black humor．The author uses silly and even surreal(超现实的)events．It has a non-linear narrative structure(非线性的叙述结构)in which events follow the theme rather than the timing，to give us a very strange picture full of contradictions(矛盾)．
The story takes places in a bomber base in Italy during World WarⅡ．The main character, Captain Yossarian wants to leave the war．Unfortunately, every time he completes the number of tasks to be sent home，the number is raised and he is forced to continue fighting．It seems hopeless for him to go home under the very strange rule in this Air Force-catch-22：only when a soldier goes crazy can he be allowed to go home．But he has to go to the hospital to show the doctors that he is crazy．However, if he tells them he is crazy but is obvious healthy, he cannot go home．In short，catch-22 is“heads 1 win，tails I lose．If you can you can’t；and if you can’t，you can．”Whenever you try to behave correctly in a crazy world．There’s a catch(潜在的困难)．
During the Vietnam War, the phrase“catch-22”became a popular term for being caught in a no．win，circular dilemma and is now commonly used． The Oxford English Dictionary explains catch．22 as“a set of circumstances in which one requirement，etc，is dependent upon another, which is in turn dependent upon the first．”
1. Which of the following statements is right?
A. Catch-22 is one of Heller’s experiences during World War II．
B. Catch-22 is one of Yossarian’s experiences during the Vietnam War．
C. The events in catch-22 follow the theme．
D. The events in catch-22 follow the timing．
2.Why did Captain Yossarian fail to leave the war?
A. He wasn’t so anxious to leave the war．
B. He didn’t finish his tasks．
C. He was put into a catch-22 situation．
D. He wasn’t mad enough to be sent home．
3.What does the underlined sentence most probably mean?
A. Whenever and however you try, you are unable to reach the goal．
B. You can solve every problem you meet as long as you want to．
C. You can’t solve any problem in your life．
D. If you can’t solve all the problems．you can solve none．
4.The phrase“catch-22”came into being ________ _．
A. in World War II B. in the Vietnam War C. in the 1950s D. in the 1960s
