这是一篇说明文。文章介绍了一种旨在防止鲨鱼袭击技术Shark Spotter的工作原理以及重要意义。 【42题详解】

推理判断题。答案定位在第四段If a shark is detected, Shark Spotter provides both a visual sign on the computer screen and an audible warning to the

operator. The operator confirms the warning and sends text messages from the Shark Spotter system to the Surf Life Savers for further action.（如果鲨鱼被发现，Shark Spotter会在电脑屏幕上显示视觉讯号，并向操作员发出听觉警

告。操作员确认了警告，并从鲨鱼观测者系统向冲浪救生员发送短信，以便采取进一步行动。）由此推断出Shark Spotter是一种防止鲨鱼袭击的技术，故选C。 【43题详解】

推理判断题。答案定位在第四段In an emergency, the drone is equipped with a lifesaving flotation pod (漂浮仓) together with an electronic shark

repellent (驱逐装置) that can be dropped into the water in cases where swimmers are in severe trouble, trapped in a rip, or if there are sharks close by.（在紧急情况下，无人机配备了一个救生浮选舱和一个电子防鲨器，当游泳者遇到严重麻烦、被困在裂口或附近有鲨鱼时，可以将防鲨器放入水中。）由此可知当在游泳者附近发现鲨鱼时，系统会及时采取行动，故选A。 【44题详解】

的推理判断题。第五段In January 2020, the Westpac Little Ripper Lifesavers was used to rescue two young swimmers caught in a rip at Lennox Head, NSW. The drone flew down the beach some 800 meters from the lifeguard station, and a lifesaving flotation pod was dropped from the drone. The complete rescue

operation took 70 seconds.（2020年1月，西太平洋小开创者救生员队(Westpac Little Ripper Lifesavers)被用来营救两名在新南威尔士州伦诺克斯海德(Lennox Head)被困的年轻游泳者。这架无人机从距离救生站800米的海滩上飞下来，一个救生浮筒从无人机上掉了下来。整个营救行动耗时70秒。）由此推断出第五段的例子告诉我们这个系统在拯救生命方面是有效的，故选A。 【45题详解】

推理判断题。答案定位在最后一段We believe Shark Spotter is a win-win for both marine life and beachgoers.（我们相信Shark Spotter对海洋生物和海滩游客来说都是双赢的。）由此推断出作者对Shark Spotter的未来持乐观的态度。A. Doubtful.怀疑的；B. Optimistic.乐观的；C. Negative.否定的；D. Objective.客观的，故选B。

【点睛】通过对关键词，关键短语或者是关键的句子的把握是解决推理判断题的重要解题方法之一，它们往往隐藏着深层的意思。小题4，答案定位在最后一段We believe Shark Spotter is a win-win for both marine life and beachgoers.（我们相信Shark Spotter对海洋生物和海滩游客来说都是双赢的。）其中a win-win是关键词，由此推断出作者对Shark Spotter的未来持乐观的态度，故选B。

Nowadays, WeChat is about expressing our opinions and Weibo is about collecting things we like. Both of them develop our self-focus. Self-focus simply means you pay attention to how you feel, think and behave. Self-focus isn’t naturally a bad thing. Particularly in individualistic (个人主义的) cultures, we value our ability to be self-aware. ___46___

Unfortunately, when you are regularly focusing on yourself, you’ll notice any dissatisfaction, anxiety, or general discomfort you might not have

otherwise. ___47___ As a result, self-focus contributes to a wide range of mental health problems like anxiety.

But quitting technology is no longer a practical solution. ___48___ For example, don’t post about things you did, which focuses your attention on yourself.

In this way, you won’t focus so much on your bad hair day, and you will get along better with your friends.

___50___ But if we can learn to move the focus off ourselves and onto doing good for others, technology can help us grow. Anyway, the point is that it’s up to you to handle the ability of your self-focus. A. Too much self-focus means few friends.

B. Self-focus is generally helpful in daily life. C. Therefore, try taking pictures of your friends.

D. In fact, we can use technology in ways that are less self-focused. E. By bringing your attention to those negative emotions, you strengthen them.
