21、Chinese cuisine is widely known and enjoyed all around the world, Who doesn’t long for a favorite Chinese dish? But there is one interesting concept concerning Chinese food which is almost unheard in the West, and which is becoming increasingly ignored by the youth of the East—the ancient custom of tonic food.
Tonic food is food which is consumed to improve one’s well-being or avoid sickness. For instance, it was once the custom for new mothers to eat a sesame oil hotpot every day for the first month after giving birth. It was believed that this dish would benefit the muscles, reduce pain, improve circulation, stimulate sweating, and warm the body. Some foods, such as goat meat and spinach(菠菜), are seen as “hot”, while others, such as Chinese cabbage and radishes(小萝卜), are seen as “cold”. One should be careful not to eat too much of either “hot” or “cold” food, However, how much “hot” or “cold” food one should eat depends on the time of the year, how the food is prepared and what it is prepared with, and the individual’s health.
The custom of employing tonic food for a healthier life also influences the catering industry. Chinese herbal medicines, such as the wolfberry, can be found on many a restaurant menu, either added to fruit tea or as a beneficial addition to a dish. These herbs attract customers, such as overworked office staff, in need of a modest pick-me-up.
So, whether you need to boost your strength with a large helping of chicken soup, or increase your mental powers with a serving of pig brain soup, you may find that this ancient Chinese custom could be just the tonic you were looking for.
【1】What is the present situation of tonic food?
A．It is catching less attention.
B．It is well known worldwide.
C．It is enjoyed by many young people.
D．It is becoming increasingly popular.
【2】What is believed to benefit new mothers?
A．Chinese cabbage.
B．Fruit tea.
C．Sesame oil hotpot.
D．Pig brain soup.
【3】Which of the following best explains “catering” underlined in paragraph 3?
A．Medicine.
B．Restaurant.
C．Education.
D．Fashion.
【4】What can be a suitable title for the text?
A．The Charm of Chinese Cuisine
B．The Popularity of Tonic Food
C．Some Information about Chinese Tonic Food
D．Differences Between Hot Food and Cold Food
22、Passwords don’t have to be a pain. There’s a way to choose and remember them with confidence. With the right approach, you can start using the process to your advantage, by setting passwords that also strengthen your memory.
Passwords should be complex and varied enough to be secure, yet still memorable. But with so many to keep track of, this can be hard to achieve. No wonder so many people use the same password over and over again or simply write them all down!
A much better idea is to follow a system. You save time at the setting stage, and have a clear pattern for your memory to follow. It’s good exercise for your brain and a valuable way to protect your identity online.
The following system uses letters, numbers and symbols, so it will please even the strictest website. And the random-looking codes it produces would be extremely difficult for someone to crack, but just enough of a challenge for your brain. First, choose a short quotation, one that no one would have any reason to associate with you. Pick out the initial letters—creating the first “building block” for your passwords. So, if you chose, “Play it again, Sam,” you’d have the letters PIAS.
Next, choose a meaningful date—again, one that can’t be guessed or easily researched. Maybe the year of a favourite holiday, 86, say.
Then add a random element by picking any two keyboard symbols: for example, & and £.
Finally, organize these building blocks in any order you like. And strengthen the code further by making some of the letters lower case, and some upper: maybe 86&£PiAs.
Spend a little time getting to know this “foundation” for your passwords. “See” it in your mind’s eve. And then start using it as the basis for every new password you set. Add two or three extra letters each time, a few initials or abbreviations to remind you of what this particular password is for. For example, you might use BT for your phone account or CC for the camera club forum so the final password for your BBC account could be: BBC86&£PiAs.
With a system like this, you’ve got a basic formula to follow. But each password ends up being complex and unique, helping to protect your identity and giving your memory a cracking workout every time.
【1】A password is supposed to be________.
A．complex and long
B．unique but easy to crack
C．complex but easy to remember
D．secure and difficult to remember
【2】According Paragraph 4, if you choose the quotation “Speak louder, please”, what “building block” will you get for your password?
A．KRE.
B．SLP.
C．PLS.
D．EUA.
【3】What’s the third step in setting a password?
A．Think of a short sentence.
B．Select a proper number.
C．Choose two keyboard symbols.
D．Make some letters lower case.
【4】Which of the following passwords best suits the recommended system in the text?
A．HW03@*AsLT.
B．123456#.
C．QQ010&XYz.
D．!!!123Cba.
23、Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.
Car washes have been automated for decades, but companies developing fully autonomous vehicles must rely on a human touch to keep their cars and trucks in working condition.
【1】For example, soap residue or water spots could effectively "blind" an autonomous car. A traditional car wash's heavy brushes could jar the vehicle's sensors, disrupting their calibration and accuracy. Even worse, sensors, which can cost over $100.000. could be broken.【2】Dirt, dead bugs, bird droppings or water spots can impact the vehicle's ability to drive safely.
Avis, which has years of experience managing large fleets of rental cars, has been tasked with cleaning and refueling the self-driving van fleet of Waymo, the self-driving arm of Google's parent company. Avis modified three of its branches in the Phoenix area to tend to the Chrysler Pacifica vans. “There are special processes that definitely require a lot more care and focus, and you have to clean [the vans] quite often.”
【3】But other self-driving car companies such as Toyota, Aptiv, Drive. AI and Uber described to CNN that they use microfiber cloths along with rubbing alcohol, water or glass cleaner for manual cleanings.
【4】This should alleviate some need for manual cleaning. But because autonomous vehicles can have dozens of sensors, Seeva CEO Diane Lansinger doesn't imagine products like this will be able to clean every camera, radar or LIDAR, a laser sensor that most experts see as essential for self-driving vehicles.
A.The sensors on a fully self-driving car require special care.
B.Orduña wouldn't reveal exactly how they' re washing the vehicles.
C.The most advanced cars on the planet require an old-fashioned handwashing.
D.Meanwhile, some companies, such as Cruise, are building sensor cleaning equipment into their vehicles.
E.There are a range of problems with putting a self-driving vehicle through a traditional car wash, experts say.
F.A self-driving vehicle's exterior needs to be cleaned even more frequently than a typical car because the sensors must remain free of obstructions.
24、Talking plants might sound like characters in a fairy tale. But recent scientific studies have shown that plants communicate with each other and with other living things in a surprising number of ways. To understand them, scientists say, we just have to learn their language. Farmers are especially interested in what plants have to say.
“Plants are able to communicate with all sorts of organisms(有机体). They can communicate with giant bacteria, with other plants and with insects. They do this chemically, ”said Cahill, an Ecology Professor of the University of Alberta in Canada.
Plant scientists are just beginning to understand this chemical “language”. Cahill says studies have shown, for example, that plants can evaluate conditions in their immediate environment and take appropriate actions. Plants have an ability, for example, to signal pain or discomfort caused by anything from temperature extremes to an insect attack. Jack Schultz, a professor of chemical ecology at the University of Missouri, says when a plant senses that it’S being eaten, it cannot walk away from trouble；on the contrary, it will release a chemical vapor that alerts other plants nearby.
“Their language is a chemical language, and it involves chemicals that move through the air, which are easily to be changed, and most of all are smells that we are familiar with, ” Schultz explained.
“All plants responded to the attack by changing their chemistry to defend themselves, ” Schultz recalled. “But we were quite surprised to find that nearby plants also changed their chemistry to defend themselves, even though they were not part of the experiment. ”
Studies have also shown that plants under attack release pleasant chemicals. Those chemicals attract friendly insects that attack the pests eating the plant.
In the end, plants’ability to communicate their needs－and our ability to understand them－could help farmers reduce the use of poisonous chemicals, cut operating costs and limit damage to the environment.
【1】The recent scientific studies have shown that plants can __________.
A. communicate with other living things in a chemical way
B. hardly react to any sudden change in temperature
C. use a very special chemical language which is familiar to us
D. respond to the attack by giving off poisonous chemicals
【2】When being eaten by a pest, the plant will ___________.
A. walk away from trouble
B. change its chemistry to kill the insect
C. release a chemicaI vapor to “ask” other plants for help
D. give off nice chemicals to attract friendly insects to a tack the pest
【3】The underlined word “alerts” most probably means “___________”.
A. warns B. protects
C. threatens D. allows
【4】Which would be the best title for the passage?
A. Communication between Plants
B. A Chemical “Language”
C. Plants Can Talk
D. How Plants Protect Themselves
25、I seldom cooked before the isolation (隔离). I thought little of cooking either. But in troubled times I’ve been ________ to cook every day and thus ________ my feelings about it.

A heavy hand or wrong timing can ________ its failure. All these remind me I was so ________ before, taking for granted the effort, creativity and skills which cooking routine meals ________. Cooking ________ is a fun and novel experience, but cook every day and you ________ the importance of organization, preparation and efficiency.
