Meanwhile, there exist many disadvantages as well. The teenagers addicted to playing computer games or chatting online will be more likely to withdraw from society, which does great harm to their physical and mental health.

Her mother, Divya Gupta had a suggestion: write an app. She was half-kidding, but Medha took the challenge seriously. So she went to work. The result was Safe Travel, an app designed by Medha to help walkers feel more ______ when travelling alone. Using a smartphone, a person can programme it to send a warning to someone he or she trusts if he or she fails to arrive at a destination within a certain time. It was the first IOS app that Medha had created. While she didn't think much would come from the project, her effort caught the eye of judges for the annual Congressional App Challenge, who selected her as the winner for Virginia's 10th District. secure The App Challenge is designed to encourage students to consider careers in science, technology, engineering, and maths by experimenting with coding and computer science. Winning students are invited to attend a reception on Capitol Hill in April and also receive $250 in Amazon Web Service credits. Medha said it took her about 40 hours to design, programme and test the app. As for her next app, Medha is not certain. She temporarily has her app-development tasks on hold because she's busy teaching herself AI to help deal with improper words on the media. Yes, she knows that there are teams of engineers possibly doing the same thing. But she figures it can't hurt her own part, too. “If we see something wrong with the world, we should do something about it，” she said. “After all, the only one stopping us from doing something is ourselves.” 语篇解读：本文是一篇记叙文。文章讲述了Medha Gupta在母亲的建议下，开发应用程序并获奖的故事。 1．What did Medha Gupta's mother advise her to do?

A．Satisfied.　　　 B．Safe. C．Trusty. D．Dangerous. √ 解析：词义猜测题。根据画线词后文“Using a smartphone, a person can programme it to send a warning to someone he or she trusts if he or she fails to arrive at a destination within a certain time.”可知，运用该程序能使人避免危险，更加安全，故画线词意为“安全的”。 4．What message does Medha seem to express in the last paragraph? A．Never too old to learn. B．AI leads to a better future. C．Always be creative in life. D．Practice makes perfect. √ 解析：推理判断题。根据最后一段可知，本段中Medha表达了在生活中应该始终保持创造性。 (二)阅读七选五 Most children now chat daily either online or through their mobile phones. ___ Some are shy in real life but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.
