【題目】閱讀理解
In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse(詛咒);in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets(藥丸)that contained mercury(水銀), believing that it would make them immortal, but they died afterward.

Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?
An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.
The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars(毛毛蟲), frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.
"Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."
A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.
The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances(物質(zhì))that we regularly ingest(攝入)-chili, coffee and chocolate-owe their special flavors or stimulating(提神的)effects to chemicals that plants make to poison insects.
根據(jù)短文內(nèi)容,選擇最佳答案,并將選定答案的字母標(biāo)號填在題前括號內(nèi)。
(1)What does the underlined word "immortal" in Paragraph 1 mean?
A.happy
B.not moral

A.To give people more in-depth knowledge about poison.
B.To teach people how to handle poisonous animals.
C.To inform people about which animals are the most poisonous.
D.To show how poison has been used for medical treatment.
(3)Which of the following statements about the Golden poison frog is TRUE according to the article?
A.Its skin can cut off the signaling power of your nerves.
B.It's about the size of a coin.
C.It's the most poisonous animal on display.

Andre Chiang, a Michelin-star chef and owner of RAW in Taipei, said he has been 5 with the texture at his restaurant, which uses only local materials. “It’s like aldente (筋道) but not quite,” Mr. Chiang said.

Q is so well 6 in Taiwan that many in Hong Kong and across the Taiwan Strait in mainland China use the term as well.

There are many other uses for the term Q in Chinese as well. It could be used, for example, as short form for the English word “7”, or to refer to the once-popular QQ messaging service from Tencent.

Among the local people, the 8 for Q texture starts at a young age. On a recent sticky evening at the Lehua Night Market, a group of people gathered at stand with a sign that 9 “QQ ice lolly.” Asked why Q texture was so 10 to Taiwanese, Lu Wei-chen, the owner of the stand, smiled as she handed a bright red jelly bar to a delighted toddler.

“It’s simple,” she said. “When you eat it, you will be in a good mood.”
