Ⅰ．完形填空(10分)
We can't remember clearly since when we started to take our mobiles to a dinner table．This happens a lot, especially when we go out to have dinner．Once a dish comes, instead of lifting our chopsticks, we take out our 1 and click(点击)．Later, we post the photos on the internet, waiting to be “liked”．Then we check our mobiles from time to time during the meal, to see 2 we get “liked” or not．We just cannot leave our mobiles for only a meal．
Does that sound similar to you Do you do that often If not, how do you 3 when others do that when having dinner with you
A recent study suggests that what we are used to doing is not so good．Spending time taking photos of 4 makes the food less pleasant．To test this, some researchers did an experiment．Some people were asked to take photos before they could enjoy food．As a result, it showed that the more photos they took, the 5 delicious the food seemed to them．So, why not stop taking photos and just enjoy the food in front of you
Besides the scientific result, there are also some other bad influences of taking photos of food before meals．After 6 the photos onto the internet, one will not be able to control himself and check his mobile many times．“Does everyone like my photos I hope a lot of people like 7 ！” It seems that your mobile secretly calls your name all the time, even when you are 8 real people．
So, next time you 9 with your family or friends, how about not taking photos of food Let the food be delicious as it is, and 10 your life with people around you．Trust me, it will be a wonderful time．
(　B　)1．A．books B．mobiles
C．cameras D．watches
解析：考查名词辨析。句意：一上了菜，我们就拿出手机点击，而不是举起筷子。book书；mobile手机；camera照相机；watch手表。由空后“click(点击)”可知空处表达“手机”。
(　D　)2．A．when B．how
C．what D．whether
解析：考查连词辨析。when当……时候；how怎么样；what什么；whether是否。由前文“随后，我们将照片发布到网上，等待‘点赞'。 然后，我们在用餐期间不时地检查手机”和空后“or not”可推知此处表达“看看我们是否被点赞”。
(　C　)3．A．do B．hope
C．feel D．say
解析：考查动词辨析。句意：如果不，当别人和你一起吃饭做那件事情时你感觉怎么样？do做；hope希望；feel感觉；say说。do, hope和say都是及物动词，后面必须接宾语，排除这三项。
(　C　)4．A．friends B．family
C．food D．people
解析：考查名词辨析。friend朋友；family家庭；food食物；people人，人们。句意：花时间拍摄食物的照片会让食物变得不那么美味。由第一段中“Once a dish comes, instead of lifting our chopsticks, we take out our．．．and click(点击)．Later, we post the photos on the internet, waiting to be ‘liked’．”可知，就餐时拍摄的是食物的照片。
(　B　)5．A．little B．less
C．least D．more
解析：考查比较级。由下文“So, why not stop taking photos and just enjoy the food in front of you？”可推知，本题所在句子意为：结果显示，他们拍的照片越多，他们觉得食物就越不美味。结合句意可知此处考查“the more．．．, the less．．．”结构。
(　B　)6．A．taking B．posting
C．throwing D．giving
解析：考查动词辨析。句意：照片传到网上后，一个人将无法控制自己，并多次查看手机。take拿走；post邮寄，发布；throw扔；give给。由空后“onto the internet”可推知空处表达“发帖子”。
(　A　)7．A．them B．it
C．me D．us
解析：考查代词辨析。由上句“每个人会喜欢我的照片吗”可推知空处指代“我的照片”，故使用代词they来代替，因放在动词like后使用其宾格形式them。
(　D　)8．A．around B．to
C．from D．with
解析：考查介词辨析。around在……周围；to到；from从；with和……一起。由前半句“似乎你的手机一直在偷偷叫你的名字”可推知此处表达“即使你和真人在一起”。
(　A　)9．A．eat out B．set out
C．come up D．have fun
解析：考查动词短语辨析。句意：那么，下次你和家人或朋友外出吃饭时，不拍食物的照片怎么样？eat out在外面吃；set out出发；come up提出；have fun玩得开心。 由第一段的“This happens a lot, especially when we go out to have dinner．”可知，上文谈论的是“外出吃饭时使用手机给食物拍照的事情”。
(　D　)10．A．treat B．avoid
C．talk D．share
解析：考查动词辨析。treat对待；avoid避免；talk交谈；share分享。由前半句“Let the food be delicious as it is(让食物变得美味)”可推知此处表达“与你周围的人分享你的生活”。share．．．with．．．意为“和……一起分享……”。

Paper was invented in the Western Han Dynasty in China and Cai Lun improved it around 2，000 years ago．It is an important invention．Before the invention of paper, people had to remember lots of information or write it on stones, wood, leaves, etc．

Dear Mary，
How are you Last time you asked me about the greatest invention in my eyes．I have also discussed it with my best friends, Anna, Sue and Kris．We have different ideas．Anna thinks it is the high speed railway; Sue, the shared bike; Kris, the online shopping; and I prefer the internet．
The internet is just like a net, and it connects us with the world．In the past, it was nearly impossible for people to communicate immediately with people in other countries．They had to spend a long time to reach their destinations(目的地), and not everyone could do that．But the internet has made the impossible possible．Now we can communicate with foreigners online．
The internet also helps us know what is happening around the world, and has made our life and work easier．In recent years, shopping online is very popular．We can just stay at home and buy what we need online．We can also do online office work．Besides, we can watch movies, listen to music and even play games to relax ourselves on the internet．
So I think that the internet is one of the greatest inventions．It has changed our world! Although there are still many problems with the internet, they will be solved in the near future．As students, we should make good use of the internet!
Yours，
Peter

OPINION AI
　　In each Opinion section of the The New York Times for Kids: China, we visit a different Chinese school and invite kids to express their opinions on a certain topic(话题)．In March, we went to Shenzhen Bay School to record students' opinions on how humans and AI(人工智能) get along． Andy—15 years old A huge difference between AI and humans is that robots don't create new things, and they don't get bored with things．Take the floor cleaning robots as an example: They can sweep the floor for many years without getting bored, but we humans would get bored quite quickly．We instinctively(本能地) want to create new things, and that's where we have an advantage over AI． Eileen—13 years old I want to add a pair of “super long distance” glasses(千里眼) in my eyes so that I can see interesting or dangerous things sooner．I could look out of the window and see people I miss faraway． I could also predict earthquakes．In this way, I can help warn people of the coming danger． Eva—14 years old I don't want my memories to be changed or improved, because every memory is beautiful and worth recalling．But if it must be changed or improved, I would bring back all the memories I had as a baby that I've forgotten．My family is always happy whenever they talk about when I was a baby．I think they would be good memories, and I wish I could have them back．
