The aroma of chocolate perfumes the air of the Rue dAssas in Paris. Entering Christian Constants state-of-the-art boutique, you find yourself in the kingdom of Pariss king of chocolate, where the humble cocoa bean is turned into mouth-watering chocolate Easter eggs. Constant, who is a chef, admits that chocolate is his passion and main interest in life. He first developed a fascination with chocolate when he was working for Gaston Lentre, a famous French pastry chef. Every year he has a theme for decorating Easter eggs:this year his decorations are inspired by "Art Nouveau" . Tonight he has a dinner for 130 to organize and he has to prepare a three-foot-high Art Nouveau-style. Easter egg by noon tomorrow. This, for Constant, is a normal schedule. Constant believes that his chocolate creations are as much of a work of art as other sculptures. It is, therefore, understandable that the restaurant, which he opened last month, is situated in the National Monuments Museum in Paris. During the day the restaurant is a tearoom and offers chocolate in every imaginable form. Customers can choose from a selection of sweet chocolate desserts or try the more exotic spicy chocolates. Constant is also a professional "nose", working closely with the French Institute of Taste. He is capable of identifying 450 different tastes and flavors. Constant explains that the mouth, which can only taste four things—salt, sweet, acid and bitter—is "stupid" in comparison to the nose. He believes that the nose is everything. In his book The Taste of Chocolate, he explains how in 1502 Christopher Columbus came across an island and went ashore. He was greeted by an Indian chief bearing gifts, among which were huge sacks of beans which Columbus thought was local currency. To his surprise, they prepared a drink for him. But Columbus, who disliked the odd bitter taste, continued on his travels, ignorant of the fact that he had just tasted cocoa. Like Columbus, Constant travels the cocoa countries where he checks quality and works with local experts. Quality can vary depending on the region, year, and method of preparation. According to Constant, Venezuela and Trinidad have the best cocoa beans, which they export all over the world either as beans or as cocoa. Constant, who is a hard worker, only sleeps three hours a night. He talks long into the night with mem bers of a club he has formed. The club is called "The Chocolate Munchers". Their main official activity is to get together for monthly dinners where they eat a very tiny dinner and tons of chocolate desserts. "I am an addict," Constant admits, "and I dont want to be cured! "

Which of the following is the most inclusive title for the passage?

A．Chocolate—The Passion of a Lifetime

B．The Chocolate Munchers Club

C．Chocolate—A New Art Form

D．The Last Word in Good Taste

The sensation of pain cannot accurately be described as "located" at the point of an injury, or, for that matter, in any one place in the nerves or brain. Rather, pain signals—and pain relief—are delivered through a highly complex interacting circuitry. When a cell is injured, a rush of prostaglandin s sensitizes nerve endings at the injury. Prostaglandins are chemicals produced in and released from virtually all mammalian cells when they are injured: these are the only pain signals that do not originate in the nervous sys- tern. Aspirin and other similar drugs(such as indomethacin and ibuprofen)keep prostaglandins from being made by interfering with an enzyme known as prostaglandin synthetase, or cyclooxy- genase. The drugs effectiveness against pain is proportional to their success in blocking this enzyme at the site of injury. From nerve endings at the injury, pain signals move to nerves feeding into the spinal cord. The long, tubular membranes of nerve cells carry electrical impulses. When electrical impulses get to the spinal cord, a pain-signaling chemical known as substance P is released there. Substance P then excites nearby neurons to send impulses to the brain. Local anesthetics such as novo-caine and xylocaine work by blocking the electrical transmission along nerves in a particular area. They inhibit the flow of sodium ions through the membranes, making the nerves electrically quiescent; thus no pain signals are sent to the spinal cord or to the brain. Recent discoveries in the study of pain have involved the brain itself—the supervising organ that notices pain signals and that sends messages down to the spinal cord to regulate incoming pain traffic. Endorphins-—the brain s own morphine—are a class of small peptides that help to block pain signals within the brain itself. The presence of endor- phins may also help to explain differences in response to pain signals, since individuals seem to differ in their ability to produce endorphins. It now appears that a number of techniques for blocking chronic pain—such as acupuncture and electrical stimulation of the central brain stem—involve the release of endorphins in the brain and spinal cord.

The passage is primarily concerned with

A．analyzing ways that enzymes and other chemicals influence how the body feels pain.

B．describing the presence of endorphins in the brain and discussing ways the body blocks pain within the brain itself.

C．describing how pain signals are conveyed in the body and discussing ways in which the pain signals can be blocked.

D．demonstrating that pain can be influenced by acupuncture and electrical stimulation of the central brain stem.

E．differentiating the kinds of pain that occur at different points in the body" s nervous system.

B.Yes; in Experiment 2, as capacitance increased, the time required to reach a given voltage increased.

C.No; in Experiment 1, as capacitance increased, the time required to reach a given voltage decreased.

D.No; in Experiment 2, as capacitance increased, the time required to reach a given voltage decreased.

What We Take From and Give to the Sea

As long as we have been on earth， we have used the sea around us. We take things from the ocean， and we give to it.

We take fishes from the ocean——millions of kilograms of fish， every year， to feed millions of people. （46） We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates. （47） Much gold and silver drift dissolved in the waters of the sea， too. But the sea does not give them up by simple evaporation.

Other gifts from the sea are pearls， sponges and seaweed. Pearls become jewelry. （48）Seaweed becomes food of many kinds——even candy， and ice cream——as well as medicine. Believe it or not， fresh water is another gift from the sea. We cannot drink ocean water. （49）But ocean water becomes fresh water when the salts are removed. In the future， we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food， fertilizer， minerals， water， and other gifts. What do we give the sea? Garbage. （50） Huge as it is， the ocean cannot hold all the water we pour into it Dumping garbage into the ocean is killing off sea life. Yet as the world population grows， we may

need the sea and its gifts more than ever.

We are finally learning that if we destroy our sea， we might also destroy ourselves. Hopefully， it is not too late.

A.Natural sponges become cleaning aids.
