M：It's cheaper than the last one we saw and it is in a good neighborhood. W：Well, maybe we'll have to see if the agent has anything else to show us. [听力分析] 本题是一个长对话题目。一是问女士不喜欢什么，二是问女士建议下一步做什么。因此听录音时应特别关注和这两点相关的问题。因为这两个都是和女士相关的问题，因此要重点听她说的内容。根据女士所说的“But there is not enough cupboard space in the kitchen.”可知，她不喜欢厨房，所以应该选C；再根据女士所说的“maybe we'll have to see if the agent has anything else to show us”可知，她建议去看其他的公寓，所以应该选B。 Part 3　交际常用语 本单元的交际用语所涉及的中心话题是信息技术。以下是该类话题的常见话题句式： 1．I love exploring new technologies，because they are... 我喜欢探索新技术，因为它们…… 2．I use this app to...online. 我用这个应用程序在网上…… 3．I also like...online. 我还喜欢在网上…… 4．Well，too much...will... 嗯，太多……会…… 5．Why are apps so popular?

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 secure when travelling alone.Using the cell phone, 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 app that Medha had created.While she didn't think much would come from the project, her efforts caught the eye of judges for the annual Congressional App Challenge, who selected her as the winner for Virginia's 10th District. 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. Medha said it took her about 40 hours to design, programme and test the app.As for her next app, Medha's 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 Internet.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]　本文是一篇说明文。文章主要介绍了Medha Gupta设计了一款名为“安全旅行”的应用，它可以帮助行人在独自旅行时感到更安全。 2 3 1 4 1．What did Medha Gupta's mother advise her to do? A．Develop an app.　　 B．Take a bus. C．Travel with others. D．Walk to school. 答案：A 细节理解题。根据第二段中“Her mother, Divya Gupta had a suggestion：write an app.(她的母亲Divya Gupta给了她一个建议：编写一个应用程序)”可知，Medha Gupta的母亲建议她开发一个应用程序。故选A项。 2 3 1 4 2．How is the App Challenge designed to encourage students to consider their careers? A．By attending the lecture about science and technology. B．By searching the online information. C．By experimenting with coding and computer science. D．By consulting the professional teachers. 答案：C 2 3 1 4 细节理解题。根据第五段中“The App Challenge is designed to encourage students to consider careers in science, technology, engineering, and maths by experimenting with coding and computer science.”可知，应用程序挑战赛是通过编程和计算机科学试验鼓励学生考虑自己的职业发展的。故选C项。 2 3 1 4 3．What does the underlined word “secure” in the third paragraph probably mean? A．Warning.　　　 B．Safe. C．Trusty. D．Dangerous. 答案：B 2 3 1 4 词义猜测题。画线词的下文“Using the cell phone, 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.”说明运用该程序使人避免危险，更加安全，从而推知画线词的意思是“安全”。故选B项。 2 3 1 4 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. 答案：C 2 3 1 4 推理判断题。根据最后一段中Medha所说的“‘If we see something wrong with the world, we should do something about it，’ she said.”可知，本段中Medha表达了在生活中应该始终保持创造性。故选C项。 2 3 1 4 B WhatsApp's much-expected “Unsend” feature is finally ready.It has been in development for months, but has now started rolling out to users. The feature, which is officially called “Delete for Everyone”， has also been widely referred to as “Recall” and “Revoke”．It lets you unsend messages, making them completely disappear from a conversation.They will be hidden from both yourself and the other people in the chat. However, both you and your recipient (接受者) need to be using the latest version of WhatsApp, and it only works for messages you have sent within the last seven minutes.Once that period of time has passed, your message is there to stay. “Delete for Everyone” can work on all types of messages, including texts, images, videos, GIFs and documents.To unsend a message, you simply need to highlight it by tapping and holding the line of text, select the “Delete” button from the menu and hit the “Delete for Everyone” option. “This is particularly useful if you sent a message to the wrong chat or if the message you sent contains a mistake，” explains WhatsApp in an FAQ (frequently asked questions).“Messages you successfully delete for everyone will be replaced with ‘This message was deleted’ in your recipients' chats.Similarly, if you see ‘This message was deleted’ in a chat, it means that the sender deleted the message.” WhatsApp says you will be informed if “Delete for Everyone” hasn't worked.It also warns that even if the feature does work successfully, there is a chance that the person you have been chatting to may have already seen the message before you decided to delete it. According to WABetaInfo, the roll-out of “Delete for Everyone” is proving very slow, so don't worry if you are unable to make use of it quite yet. [语篇解读]　本文是一篇说明文。文章主要介绍了WhatsApp推出“Delete for Everyone”功能，这个功能可以让你在一定时间内取消发送过的信息，让它们完全从对话中消失。 5 6 7 8 5．What is the main function of the “Delete for Everyone” feature? A．Deleting junk messages. B．Hiding yourself in a chat. C．Ridding unwanted messages. D．Removing messages you've sent. 答案：D 细节理解题。根据第二段中的“It lets you unsend messages, making them completely disappear from a conversation.They will be hidden from both yourself and the other people in the chat.”可知，“Delete for Everyone”功能的主要功能是删除你已经发送的信息。故选D。 5 6 7 8 6．What do you have to do in order to make the feature work successfully? A．Update your WhatsApp in time. B．Use the official version of WhatsApp. C．Create files for different types of messages. D．Handle the messages you have sent within 11 minutes. 答案：A 5 6 7 8 细节理解题。根据第三段中的“However, both you and your recipient need to be using the latest version of WhatsApp, and it only works for messages you have sent within the last seven minutes.”可知，要想使功能成功工作，你必须及时更新你的WhatsApp。故选A。 5 6 7 8 7．What does the underlined word “highlight” in paragraph 4 mean? A.Examine. B．Replace. C．Mark. D．Erase. 答案：C 5 6 7 8 词义猜测题。根据画线词上文“To unsend a message, you simply need to”以及下文“by tapping and holding the line of text”可知，要取消发送信息，你需要通过点击并按住文本行来标记你想要删除的信息，故画线词意思是“标记”。故选C。 5 6 7 8 8．What is the present situation of the “Delete for Everyone” feature? A．It lacks proper advertising. B．It still has holes to work on. C．Its reaction speed needs improving. D．It has become a big hit on the market. 答案：B 5 6 7 8 细节理解题。根据倒数第二段中的“It also warns that even if the feature does work successfully, there is a chance that the person you have been chatting to may have already seen the message before you decided to delete it.”可知，“Delete for Everyone”功能还有漏洞要补。故选B。 5 6 7 8 $$
