2.    I held my breath, trying not to sigh out loud. My seventeen-year-old son Arthur and I were leaving a holiday work function and there was plenty of leftover food that the organizers were trying to give away. Immediately Arthur honed in on a large dish of tiramisu that no one else wanted. It was enough dessert for four people, and Arthur’s doctor had warned us about watching his sugar intake.
    “Please, Gwen? Please?”
    It had been a long day, and even though Arthur tends to get exhausted by social situations that are not part of his regular routine, he accompanied me to the dinner and charmingly chatted with my colleagues until it was time to go home. The tiramisu, I reasoned, was his reward.
    As we left the restaurant, Arthur stopped next to our car to look at something.
    Standing about five feet away was a gentleman with his worn jacket, stomping his feet and rubbing his hands together in an attempt to ward off the cold. Every few seconds he smiled and tried to speak to the people who were walking by without paying him any attention. At that moment, the gentleman spotted my son watching him. “Hey man, do you happen to have any spare change?”
    Arthur checked his empty pockets and then looked at me briefly. I shook my head. Arthur frowned and then he said something that took my breath away.
    "No, I don't. But are you hungry? Do you like tiramisu? Here, you can have mine. It tastes like...”
    I blinked back tears as I watched the man’s smile broaden even more in appreciation because I knew his joy wasn’t about tiramisu. My son didn’t just give the food and walk away. He engaged the man in conversation, perhaps the first one this gentleman had all day. He treated the man as a person, with respect. The smile on the man's face told me this was the real reason for his happiness.
    People with autism definitely have feelings and emotions. Autistics can and most definitely are empathetic to others’ feelings even if they don’t know how to express it. Being kind doesn’t have to be difficult or complex.
1.We can infer that Arthur begged his mom to allow him _______.
A.to give away the leftover food B.to attend a holiday work function
C.to chat with her colleagues D.to eat a big tiramisu
2.What made Arthur frown?

3.According to the writer, the gentleman was happy because __________.
A.he got something delicious to eat B.he was treated with respect by Arthur
C.he had something to talk with Arthur D.he got some spare change from Arthur
4.What lesson did the writer learn from Arthur?
A.People with autism value logic over emotion. B.Autistic people feel painful easily.
C.People with autism have feelings. D.Kindness has to be complex.
3. On November 10, nine mini cheetah robots, built by researchers at the MIT, controlled by their human creators, showed their superior athletic abilities. The four-legged machines began with a warm-up run across the field. They then took turns playing with a soccer ball. As often happens in games, a couple of the team members got into a fight and pushed each other until both fell onto their backs. Fortunately, they made up and ended their performance with a perfect backflip(后滚翻), one that would make even a world-class gymnast proud!
Though these robots resemble their predecessors, the Cheetah 3, they are much lighter, weighing just 20 pounds. And they can bend and swing their legs wide, giving them the ability to walk either right-side-up or upside down. They can also walk at about twice the speed of an average person's walking pace. The machines can also quickly right themselves if kicked to the ground and perform 360-degree backflips from a standing position.
Unlike the Cheetah 3, the mini robots are built using cheap, easy to find parts. This means that if a leg or motor breaks, it can be easily replaced using off-shelf parts. "If you want to change something in Cheetah 3, you have to do a ton of redesign," says lead developer Benjamin Katz.
The team, which has ten of the four-legged machines, plans to build additional units and lend them to other university robotic labs. He believes this will enable other engineers to teach the robots different skills. "Eventually, I'm hoping we could have a robotic dog race through an obstacle(障碍) course, where each team controls a mini cheetah with different methods, and we can see which method is more effective," Katz says.
The MIT team's reason for developing the robots is not just for entertainment. They hope that someday packs of "cheetahs" will assist first responders with search and recovery tasks following natural disasters and work alongside firefighters.
1. What is mainly talked about in paragraph 1?
A. A fierce match between mini robots. B. Mini robots' soccer and gymnastic skills.
C. Assessment of mini robots' new functions. D. Similarities between robots and human athletes.
2. What can mini cheetah robots do?
A. They can walk on their heads. B. They can correct their mistakes.
C. They can backflip even when lying. D. They can play soccer ball with humans.
3. How do the mini robots differ from the Cheetah 3?
A. Their cost is lower. B. They can run twice faster.
C. Their appearance is changed. D. They're better received by customers.
4. Why does Katz want to have a robotic clog race?
A. To entertain people. B. To promote robotic research.
C. To teach robots different skills. D. To select robots for rescue work.
4. A recent troubling study showed that "fake news" spread significantly faster, deeper and more broadly than the truth, with the effect even more pronounced when regarding political news as opposed to reporting on natural disasters, finance or science. So how can we encourage individuals to seek accurate online content? Leading scholars are trying hard to deal with this question.
Processing new information requires a considerable mental effort, especially when that information conflicts with your existing worldview. It takes vulnerability(易伤性) and the willingness to admit you may be wrong. But with a great amount of conflicting information available, who's to say what's actually true and what's false? If you can't tell, why not just make life easy and go with what supports your current beliefs?
So what options do we have? Many suggest that addressing the issue by reforming adult behavior is aiming too far from the source. An alternative solution is using early education to help individuals recognize these problems and apply critical(批评的) thinking to the information they consume. Currently, there is a push in the US to include Internet information classes into primary and secondary school curriculums. The movement, which has received some support, aims to make fact-checking seem like second nature to individuals at an early age.
Primary and secondary school are supposed to be supplying students with the skills they need to develop into productive, informed members of our society. As our society develops, the curriculum we are teaching our students need to develop as well. We need to go further and also instruct our youth on online information literacy(识读).
The Internet is an amazing tool, but to use it most effectively we have to accept its benefits while also understanding the ways in which it makes us vulnerable. If students are still learning dated practices such as writing in school, shouldn't they be learning how to consume the Internet responsibly as well?
1. What makes it difficult to distinguish fake from real news?
A.The constant change in current beliefs.
B.The influence of different experts' beliefs.
C.The easy and peaceful life of modem people.
D.The large amount of conflicting information.
2. What do current Internet information classes focus on?
A.Building strong beliefs in students.
B.Inspiring human nature in students.
C.Developing students' critical thinking.
D.Teaching the basics of Internet information.
3. Why should we make changes to students' curriculums?
A.To reform traditional ways of education.
B.To seek new approaches to early education.
C.To make adjustments for future development.
D.To make room for individualized development.
4. Which of the following can be a suitable title for the text?
A.We Should Teach Media Literacy in School
B.School Education Requires Evolution
C.Seek Accurate Online Content Early
D.Fake News Is on the Rise

7.答案：
1. is loved
2. recently
3. caring/careful
4. to eat
5. enemies
6. When/If
7. for
8. its
9. drove
10. and
解析：1.is loved.考查时态和被动语态.大熊猫为世界各地的人们所喜爱是个客观事实,故用一般现在时;panda与love之间是被动关系,所以用被动语态.故填is loved.
2.recently.考查词性转换之形容词转换为副词.空格处修饰动词短语had a chance,应用副词.recent的副词是recently,故填recently.
3.caring/careful.考查词性转换之名词转换为形容词.空格处修饰名词mother,故用形容词.care的形容词是caring(关心他人的)或careful(细心的).在此,两个形容词在语意上都能讲得通.故填caring/careful.
4.to eat.考查非谓语动词之不定式.不定式to eat作定语,修饰前面的不定代词something.句意:25天中,她寸步不离她的孩子,甚至不去找东西吃!故填to eat.
5.enemies.考查名词复数.句意:任何气味都可能引来天敌--它们会吃掉熊猫宝宝的.天敌不止一个,所以用复数形式enemies.故填enemies.
6.When/If.考查从属连词.根据语境可知,when(当……时)和if(如果)用在此处都合适.句意:当它哭的时候/如果它哭了,熊猫妈妈会来回摇晃它,轻轻拍打,给它安慰.故填When/If.
7.for.考查介词."for+时间段"表示持续一段时间.熊猫妈妈对孩子的照顾会持续两年多.故填for.
8.its.考查代词.mother是名词,所以其前填形容词性物主代词its.故填its.
9.drove.考查时态.文章叙述了熊猫妈妈对孩子的照顾,用了一般过去时,空格处也需用一般过去时,所以用drive的过去式drove.故填drove.
10.and.考查并列连词.句意:是时候再生一个孩子了,熊猫宝宝也到独立的时候了.It was time for…和it was also time for…之间是并列关系,所以用and连接.故填and.
8.答案：
The summer holiday is coming. My classmates and I are talking about to do during the holiday. We can between staying at home and a trip. If we stay at home, it is comfortable there is no need to spend money. But in that case, we will learn little about world. If we go on a trip abroad, we can broaden view and gain we cannot get from books. Some classmates suggest we can go to places of interest nearby. I that it is a good idea. It does not cost, yet we can still learn a lot.
解析： 1．how改为what．考查特殊句式．"特殊疑问词+to do"在本句中作为短语talk about的宾语，其中what还要作为动词do的逻辑宾语．句意为"同学们和我在谈论暑假期间做什么"．
2．chose改为choose．考查句中结构．"情态动词+动词原形"才可以在句中作为谓语部分，而本句中chose是过去式．
3．take改为taking．考查动名词．本句中动名词短语staying at home与taking a trip构成并列关系，都作为介词between的宾语．
4．But改为And．考查连词．句意：如果我们待在家里，很舒服也没有必要花钱．上下文之间是并列关系，而不是转折关系，所以使用and连接上下文．
5．about后加the．考查冠词．在英语中定冠词the通常表示特指，本句中the修饰world表示特指这个世界．
6．your改为our．考查代词指代．应该使用our与本句的主语we保持一致．这句话的意思是"如果我们出国旅游，我们就拓宽视野并学到书本上学不到的知识"．
7．knowledges改为knowledge．考查名词单复数．在本文中knowledge是不可数名词，所以不用复数形式．
8． 去掉can或改为should．考查虚拟语气．主句中有suggest，意思是建议，宾语从句应该用虚拟语气结构：should+动词原形，should可以省略．
9．thought改为think，考查时态，描述现在的情况，所以用一般现在时态．
10．many改为much．考查代词．本句中代词much代替不可数名词much money作为动词cost的宾语，而many通常代替可数名词复数形式．
9.答案：
Dear David,
How are you? I'm very glad you are so interested in the annual Chinese Food Culture Show in our school. It will open on December 16, lasting about three days.
There will be various activities during the show, such as theme exhibitions, cooking shows and cooking lectures. Not only can we enjoy traditional Chinese foods but also taste local foods with unique flavors. What's more, we can realize the importance of forming healthy eating habits by attending a lecture given by a local nutrition expert.
The show is a popular Chinese food and culture event in our city. I'm really looking forward to seeing you there!
Best wishes!
Yours,
Li Hua
