阅读理解

    Having good manners(礼节)is an important part of life. You know that you should never shout in public(公共场合). But what about when it comes to the online world? When you use social media apps(社交媒体应用), like WeChat and Sina Weibo, you must also remember to mind your manners.

    For example, sometimes I need to add a new friend on WeChat. But I haven't met him or her yet in real life. So when I send them a friend request(请求), I tell them clearly who I am and how I got their contact info(联系方式).

    Just like in real life, the key to keeping good manners online is to be thoughtful. But sometimes, people forget this.

    One of my friends likes to send really long voice messages on WeChat. It is difficult to keep up with all his messages and remember everything. I think this is a bit bad!

    There are many other things that you shouldn't do on social media. Take a look and remember to do your best to be polite.

    Don't share your friends' WeChat contact info with people you don't know. Ask your friend first before sharing.

    Don't add someone new to your group chat without asking the other members. They might not want new people to join the group.

    If you use English, don't use all caps. IF YOU WRITE LIKE THIS, IT LOOKS LIKE YOU'RE SCREAMING. DON'T DO IT.

 阅读下面材料,从每题所给的A、B、C、D四个选项中选出最佳选项。

①Google's company, DeepMind, recently announced that their research team has created a ping-pong robot. This robot can play at the same level as human amateur (业余) players.

②The research team wrote about their work on a website called arXiv. A team member said, "This is the first learning robot that can play ping-pong as well as human amateurs. " The robot has a six-axis robotic arm that can move back and forth and side to side on a rail at the bottom.

③In 29 games against human players, the robot won 13 times, which is a win rate of 45%. The human players were all new to the robot, and their skill levels ranged from beginners to advanced players. The researchers said, "The robot lost all the games against high-level players but won all the games against beginners and 55% of the games against intermediate players."

④To make the robot play at a human level, the team used a layered and modular strategy(分层和模块化的策略).This means the robot can do basic skills like forehand topspin and backhand blocks. It also has a high-level controller that acts like a brain. During a game, it can choose the best moves based on the game situation, the robot's abilities, and the opponent's skills. After the game, the robot can analyze (分析) the data and improve its skills.

⑤The researchers noted that the robot still has some weaknesses. For example, it is not very good at backhand shots and has trouble with fast, high, low, or strongly spinning balls. They plan to improve the robot by making better control algorithms(算法)and better hardware.
