問題詳情：
One day, Lindsay and Erica were sitting at Lindsay’s house working very hard. Fourth grade was tough, and they were working on a science project about weather. Lindsay was a hard worker like Erica, so the two girls were happy to have each other as partners. They were writing about rain and were amazed to learn that Hawaii is the world’s wettest place. Lindsay found that Mount Waialeale, on the island of Kauai, gets about 460 inches of rain a year! In 1982, Mount Waialeale set an all-time world record when it received 666 inches of rain! The girls knew that their classmates would find all these facts interesting.
The girls were enjoying the fun facts they were finding when all of a sudden, Lindsay saw Erica choking. Erica had been chewing on a pen cap and had accidentally swallowed it! Erica started pointing to her neck. Lindsay asked her if she was choking. When Erica nodded to say yes, Lindsay quickly stood up and did the Heimlich maneuver (策略) to try to help Erica stop choking.
Lindsay was afraid of hurting her friend, so the first time she tried the Heimlich maneuver, she did not do it very hard. She tried a second time, and nothing happened. After trying it a third time, the pen cap flew out of Erica’ mouth!
Erica was very grateful to Lindsay. She was terrified when she realized she had swallowed the pen cap and could not breathe. Lindsay was very brave and saved her friend. This was one science project that both girls would never forget!
