21、 What do you use your fridge for: It can not only keep your food cold, but also make ice and freeze food. But in the future smart fridges may do much more than you can think. They may tell you what food is inside, what food you need, what food is healthy for you, and even shop for you, too!
Some companies are making online fridges which have a computer screen on the door. And it can be very useful that the computer is linked to a supermarket through the Internet. For example, when you finish your orange juice, you can put the empty juice carton (纸盒包装) near the computer screen. The computer reads the bar code on the juice carton. Then it orders more orange juice from the supermarket. You can also use the computer screen to order other things from the supermarket. The computer screen has a series of things that are in the store. You can choose what you need. The supermarket will send the food to your home.
Companies are making other kinds of “smart” appliances (电器), too. There is a new kind of microwave oven (微波炉) which has a computer memory. It can remember 365 different cookbooks. There is also a smart mixer that can remember cookbooks. Even it can test ingredients for you!
Of course, sometimes these smart appliances don’t work. When they do, they will tell you. And then they can call someone to fix them, too!
【1】Your fridges can do the following things except .
A.keep food warm B.make ice
C.keep food cold D.freeze food
【2】What’s the meaning of the underlined word “linked” in paragraph 2?
A.prepared B.connected

【3】Which is not true?
A.The oven can call someone to fix itself when it doesn’t work.
B.The oven can store 365 cookbooks.
C.The mixer can test ingredients for you.
D.The mixer can help you clean the kitchen.
【4】What is the main idea of the text?
A.Online fridges have a computer screen on the door.
B.Fridges of the future will order food from the supermarket.
C.Smart appliances, like online fridges, can be very helpful.
D.People won’t have to go to supermarkets to buy food in the future.
22、 We all know that little excitement from creating a popular post on Facebook. Watching the number of likes can be both attractive and addictive.
That same buzz (兴奋) can have its disadvantages, though. We all know the feeling of watching other people’s posts get unending positive feedback. We tell ourselves that the only reason why these people are getting attention is that they’re popular and good-looking. We sink into self-loathing (自我讨厌) and comparison. Therefore, after experimenting with hiding likes on Instagram in select countries, Facebook is exploring doing the same on its main platform.
That Facebook is considering this is encouraging. After years of appearing to ignore criticism about its effects on society, the company finally seems to be listening. However, there is a basic conflict between Facebook’s business model and its new-found altruism (利己主义). Relying on Facebook to look after its users’ mental health is a bit like asking McDonald’s to keep its customers’ blood pressure under control: At some point, a company’s need to make money is not in line with its supposed desire to do good.
The problem with likes is that they mark out how successful or happy others are, which in turn can promote a feeling of envy and insecurity. It’s a real phenomenon. However, Facebook would certainly want you to post things that get more likes. The company’s success relies upon you posting more and encouraging more “engagement” from other people so that the value of Facebook’s targeted ad business increase.
Facebook’s reliance on engagement is deep-rooted, and it destroys a supposed desire to prevent the platform from encouraging envy. Without a doubt, hiding likes can have some benefit, but the way Facebook is built means that this will always be a small step at best.
【1】Why does Facebook try hiding likes on its main platform?
A.To catch more users’ eyes.
B.To reduce envy from other people.
C.To speed the operation of the platform.
D.To encourage users’ posting positive things.
【2】What can we infer from the comparison between Facebook and McDonald’s?
A.Facebook focuses more on the users’ interests.
B.Facebook cares less about users’ mental health.
C.Facebook makes a lot of money from the users.
D.Facebook does better than McDonald’s in service.
【3】What does more “engagement” mean to Facebook according to paragraph 4?
A.The growth of value. B.More users’ needs.
C.The increases of desire. D.More users’ security.
【4】What is the author’s attitude towards Facebook’s hiding likes?
A.Critical. B.Positive.
C.Objective. D.Indifferent.
23、The Youth Science Discovery Experience (YSDE) teams students and teachers with practicing scientists to pursue semester-long (整个学期) projects in fields of science, technology, engineering, and mathematics.
Goals
Introduce new scientific topics, especially those not typically covered in traditional courses in high schools.
Encourage lifelong learning in science, technology, engineering, and mathematics.
Develop science reasoning skills and an understanding of the scientific research process.
Prepare students to face challenges of college, career, and continuing education.
Develop creativity, build self-confidence, and promote friendship among the youth.
Program Overview
The YSDE program uses a project-based learning model. Each research team consists of six tenth-grade students, one teacher, and one practicing scientist. Together the team investigates an area of current scientific concern.
The program integrates in-residence experiences with continuing education activities conducted in the students’ and teacher’s school setting. YSDE begins with a five-day residential session in the center where students will learn principles of scientific inquiry. Each research team works with its scientist to plan an approach to its project. Session in residence allows YSDE members to participate in the magnificent outdoor natural laboratory provided by the surrounding national forests. Then the teams return to their home institutions and continue working on research projects throughout the semester.
YSDE concludes with a final session in residence where teams present their research.
Program Features
Physical Environment
YSDE facilities include science laboratories, a computer center, and arts and music studios. The area provides an outstanding natural laboratory for teaching and experimentation. Being separated from the usual disturbances of cities provides a nurturing atmosphere.
Intensive (集中的), Cooperative Learning
The residential part of YSDE offers near “around-the-clock” learning opportunities in a challenging yet friendly setting. Cooperative learning encourages teamwork and cooperative skills, using science as a common language to allow students to learn from peers, staff, and visiting experts.
Professional Partnerships
YSDE’s relationship with partner organizations helps complete the program. Partner organizations are selected and invited on their interest in developing project-based learning activities for students in high school. YSDE’s partnerships with organizations like the Canaan Valley Institute and the National Radio Astronomy Observatory provide unique access to world-class facilities and human resources.

24、Simple Tricks to Get Rid of Dark Circles Under Eyes
Forget getting a corrective operation or a face lift just to get rid of those annoying dark circles under your eyes. We have gathered four simple tricks you can do at any time. 【1】.
Change your diet
Yes, unfortunately your diet could be one of the causes of those eye circles and swelling(肿胀). And when you're flying, it can be really difficult to keep a healthy and balanced diet. 【2】, so if you cut these out of your diet—especially when flying—the risk of your eyes swelling reduces. Moreover, just an ounce a day of dark chocolate and also foods that are filled with omega-3 fatty acids can greatly improve blood flow to the skin.
Cool tea bags
【3】! Don't get rid of used tea bags. Just place them in the fridge for about 10 minutes to cool off. Lie down and set the cooled bags over your closed eyes for around 15 minutes—they will be able to relieve the skin around your eyes. Therefore the swelling and discoloration(变色) around your eyes will decrease.
【4】
Here's the thing about friction—it causes skin pigmentation to darken. If you happen to be one of those people who constantly rub their eyes, here is an important reason why you should stop immediately. We know it can be hard when flying, but something as simple as not rubbing your eyes makes all the difference.
Get a retinoid cream(维甲酸乳膏)
Retinoids are a perfect solution for the area surrounding your eyes. 【5】! Moreover, they can boost collagen(胶原蛋白) so those fine lines will reduce in size and depth. Oh yes, your skin will in turn appear smooth and bright after regular and continued use.
A．Stop rubbing your eyes
B．Tea fans, this one is for you
C．So just keep them in your mind
D．But remember what you should do
E．Salty foods and alcohol cause swelling
F．Eat as much eye-friendly food as possible
G．The reason is that they quickly reduce discoloration
25、I still remember my father’s sheepish expression at breakfast the morning after he’d been invited to have dinner at a colleague’s house. _______ arriving in Brazil, back in the dark ages, he’d _______ his hosts by making a hand gesture which he had always understood to mean “OK”, but in Brazil, it meant something quite _______.
_______, he’d raised his fingers to his _______ and made a kissing sound, which again, he meant as a way of _______ that something-in this case the meal he’d just been asked to_______-was delicious.
The faux pas (失态，失礼) was_______forgotten. My father’s colleague and his wife understood he probably wasn’t yet_______of the local meaning of the gesture.

Needless to say, I didn’t use that ________ Van Gogh again.
