Pineapple is a kind of fruit that is rich in vitamins, enzymes and antioxidants (酶和抗氧化剂). The nutritional content of canned pineapple is different from that of raw pineapple. According to United States Department of Agriculture (USDA), canned pineapple is typically higher in calories and sugar. It also contains fewer vitamins and minerals. If you choose canned pineapple, try to get it with no added sugar or look for a variety that is canned in fruit juice instead of sweet liquid.
Pineapple contains a great amount of vitamin C, a water-soluble antioxidant that fights cell damage. This makes vitamin C a helpful fighter against problems such as heart disease.
Pineapple may help you keep standing tall and strong. One cup of raw pineapple pieces contains 2.6 mg of manganese, a mineral that’s important to developing strong bones. A 1994 study suggested that manganese, along with other small amounts of minerals, may be helpful in preventing bones becoming weak and breaking easily in aged women.
Pineapple can help reduce the risk of macular degeneration, a disease that affects the eyes as people age, due in part to its high amount of vitamin C and the antioxidants it contains. Like many other fruits and vegetables, pineapple contains dietary fiber, which is important and necessary for keeping you regular and in keeping your intestines (肠) healthy.
“Because pineapple is a great meat tenderizer, eating too many can lead to the pain of the mouth, including the lips and tongue,” said San Diego-based nutritionist Flores. “But, it should disappear within a few hours.” But if the feeling continues, or if you experience breathing difficulties, you should seek medical help immediately, as you could have a pineapple allergy.
Flores pointed out a possible negative to pineapple’s high levels of vitamin C. “Because of the high amount of vitamin C that pineapple contains, eating large quantities may cause some serious problems,” she said. Eating undeveloped pineapple or drinking undeveloped pineapple juice is dangerous. Undeveloped pineapple is poisonous to humans and can lead to severe diarrhea (腹泻) and vomiting.

When Stephen Mills spotted a dusty old safe (保险箱) in a museum in Canada, he thought he’d try to crack the code (破解密码), “just like in the movies”. But when he began turning the dial, he wasn’t expecting a Hollywood ending.
For years, anyone who visited the Vermillion Heritage Museum in Alberta would have passed by a large, black metal box. Staff knew it had come from the long-gone Brunswick hotel and was donated to the museum in the 1990s, but its code and contents remained a mystery for decades — until Mills unexpectedly cracked the code.
Mills, who lived in Fort McMurray, Alberta, was visiting the museum with his family last month over a holiday weekend. As they wandered around the exhibits with the museum guide, Tom Kibblewhite, they spotted the safe.
Kibblewhite told the family what he told all other guests: the 900kg black box with a silver dial had remained closed for generations. For years, the safe has confused volunteers at the museum. The manufacturer was unable to provide advice on how to open its thick door.
A locksmith (锁匠) once suggested that years of inactivity might have slowed down the gears, making it inoperable. But Mills, who is a “mechanically-minded person”, asked whether he could give it a try. “Kibblewhite kept saying no one had opened it and that it was a mystery what was inside,” Mills said. “I thought this would be a great thing to do for a laugh for the kids. Maybe they can find some interesting historical things in it — like a time capsule.”
After pressing his ear against the cool metal, he began spinning the dial. With numbers ranging from zero to 60, he turned clockwise (顺时针方向地) three times to 20, counter-clockwise two times to 40, and then clockwise one time to 60. He was astonished to hear a click. “I jumped up and told everyone I’m buying a lottery ticket (彩票),” he said.
1.What does the underlined sentence in the first paragraph mean?
A.He didn’t think he would open the safe.
B.The museum trip was like a Hollywood film.
C.He didn’t want to turn the dial in the beginning.
D.It was unbelievable for him to win a lottery ticket in the end.
2.What do we know about the safe?
A.The dial on the safe was broken.
B.It was a donation from a rich businessman.
C.It was one of the most valuable exhibits in the museum.
D.It has been long closed since it was brought to the museum.
3.Why did Mills compare the safe to a time capsule?
A.To tell people how fast time flies.
B.To remind visitors of the time limit.
C.To indicate the safe’s special meaning.
D.To explain the content of the safe.
4.What can we infer from the last paragraph?
A.Mills won a prize for cracking the code.
B.Mills had plenty of luck to break the code.
C.Mills knew what the code was in advance.
D.Mills tried a dozen times until he cracked the code.
