Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers(志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a verve activity(神经活动), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.According to Professor Barnes, theobromine ______.
| A．cannot be as effective as codeine |
| B．can be harmful to people’s health |
| C．cannot be separated from chocolate |
| D．can be a more effective cure for coughs |

Autumn blues? Let the sunshine in falling leaves, flowers, and cold winds. For many people late autumn can be a season of depression.
Those who suffer from “the autumn blue” are often extremely tired, lack energy, need more sleep, feel increased appetite and gain weight. “The exact cause of this condition, often called seasonal depression or seasonal affective disorder（SAD）, is not known yet,” says Chen Jue, associate professor at Shanghai Mental Health Center. “But recent studies indicate that weather change is influential and strongly suggest that this condition is caused by changes in the availability（得到）of sunlight.”
One theory is that with decreased exposure to sunlight, the biological clock that regulates mood, sleep, and hormones is delayed, running more slowly in winter. Exposure to light may reset the biological clock. Another theory is that brain chemicals that transmit information between nerves, called neurotransmitters （for example, serotonin）, may be altered in individuals with SAD. It is believed that exposure to light can correct these imbalances. “It is a sad season, but you can try to make it happy. Remember, spring always lives in your heart ,” Chen says. “Going outdoors to get some sunlight may reduce the tension that brings you the low spirits. Relax at work. Stretch, breathe deeply. Take a tea break. Think of your next vacation. Color treatment also works in handling low mood. Music also plays a role in treating autumn blues.”Autumn blues is also called autumn _______.
| A．depression | B．sunshine |

Which of the following CAN’T you do in order to deal with autumn blues?

At first sight, you would think the collection of hundreds of colored shards（碎片）could be a work of abstract art. But the objects are the contents of the stomach of a sea turtle that lost its battle with plastic pollution.
Environmentalists examined the stomach of the turtle found off the coast of Argentina. What they found is the symptom of the increasing threat to sea turtles from a human addiction to plastic.
Sea turtles often mistake plastic items for jellyfish or other food. Ingesting（摄取）ocean pollution can cause a digestive blockage and internal cuts. The result can be dangerous, followed by death.
Humans produce 260 million tons of plastic a year. When those products are pulled into the sea’s currents, the plastics are just broken into smaller pieces which are consumed by marine life at the bottom of the food chain. An examination of a green turtle found off Florida discovered that, over the course of a month, the animal’s faeces（粪便）had contained 74 foreign objects, including “four types of balloons, different types of hard plastic, a piece of carpet--like material and two 2--4 mm tar balls.”
“The oceans have become a giant refuse bin for all manner of plastics. All sea turtle species may be seriously harmed, “according to the biologists Colette Wabnitz, from the University of British Columbia. ”The symptom of this growing crisis can be seen inside and on sea turtles as well as their oceanic and terrestrial habitats. It is urgently necessary to directly confront the source of plastic pollution, redesign packaging and rethink the very idea of ‘throwaway culture’.”
Almost all marine species, from plankton to whales, have ingested plastic. But, even in small quantities, plastic can kill sea turtles, the biologists said.
Fifty out of 92 turtles found dead, stranded on the shorelines of Rio Grande do Sul state in Brazil, had ingested a “considerable amount of man-made debris”.What’s tile passage mainly about?
| A．How to prevent the sea turtle from plastic. |

| A．the way the biologists examined the sea turtle |
| B．some tips on how to make sea turtles avoid plastic |

According to legend, the Bridge of Sighs in Venice, Italy, which connects the Palazzo Ducale to an ancient prison, got its name because the walk across it gave prisoners on their way to jail a final chance to enjoy the beauty of the city. The view from the bridge today, however, is more likely to be of a giant billboard selling Bulgari or Coca-cola.
But when the Coke billboards went up this summer on buildings near the Piazza San Marco,which is at the historic heart of Venice, there was a public debate.
"We can't commercialize everything, " said Alessandra Mottola Molfino, a Venetian.

"I can't turn down the image of a bottle when there are pieces of the Palazzo Ducale falling to the ground, " said Renata Codello, a Culture Ministry official.
The Culture Minister has a budget of about $ 47 million (315 million yuan) for restoration of monuments. but Italy has a rich architectural heritage, and funds are always tight. Of that amount, $ 1. 8 million was given to the entire Veneto region, which includes Venice.
Two years ago, the city signed an agreement with the Dottor Group, a company responsible for the restoration of the Bridge of Sighs and the Palazzo Ducale. It allows it to sell ad space.
But there is a condition in the agreement: The ads should not offend public taste.
In August, Venice banned US actress Julianne Moore's Bulgrari ad from a billboard in the Piazza San Marco.
The photo shows a naked Moore covered with lion cubs. handbags and jewelry. Mayor Giorgio Orsoni called the image too racy (猥亵) and unsuitable for the Piazza San Marco.

| A．introduce other monuments of the ancient city |
| B．show many ancient structures need repairing |
| C．indicate that the view is blocked by huge ads |

| A．is in favor of | B．is worried about |
| C．objects to | D．doesn't mind |
