21、There is much debate nowadays as to what makes up a healthy diet. 【1】However, there is increasing evidence that the real driver of poor health is not so much fatty food, but it is so much sugar. Heart disease is the number one killer of Americans. And in America, people who receive 25% of their daily calories or more through sugar are twice as likely to die from heart disease than people who receive less than 10% a day (Journal of the American Medical Association, 2021). This is true regardless of how healthy the rest of their diet might be. Put it more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.
【2】The average American gets 1/3 of his or her sugar through sweet drinks alone. The American Heart Association recommends that we limit ourselves to less than 100-150 calories a day from sugar, which is less than what is usually contained in one can of sweet drink or in a single candy bar. 【3】You have to stop having sweet drinks altogether.
Beyond this, you can keep healthy by consuming different categories of fresh foods, especially fruit and vegetables, which are full of vitamins and fibre, rather than processed foods. 【4】They have higher quantities of sugar, salt, and fat than fresh ingredients (原料). Besides this, it is also important to have some meat, beans, or dairy products in your diet, as they provide the necessary protein for strong bones and muscle growth. As with everything in life, moderation (适度) is key. The ideal diet is a balanced one,without too much or too little of any one thing.
Finally, a fundamental key to healthy eating is to eat slowly. It takes about twenty minutes from the time when you start eating for your brain to tell your body that you are full. What this means is that people who chew too quickly end up eating too much food because they still feel hungry. 【5】It will also allow you to enjoy your food more.
A.Processed foods often contain less nutrition.
B.Don’t let food become the centre of your life.
C.Eating a large amount of food each time is not necessary.
D.Much of this extra sugar comes from sweets and sweet drinks.
E.Eating slowly also allows your body to digest your food better.
F.In other words, if you want to be healthy, you have to cut down on desserts.
G.For example, scientists have insisted for years that a big enemy of health is fatty food.
22、 As Artificial Intelligence (AI) becomes increasingly sophisticated, there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code.
Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language.
For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. “You would want that robot preloaded with a good set of values,” said Russell.
Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.
It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.
Robots could also learn values from drawing patterns from large sets of data on human behavior. They are dangerous only if programmers are careless.
The biggest concern with robots going against human values is that human beings fail to do sufficient testing and they've produced a system that will break some kind of taboo(禁忌).
One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.
If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps(嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else.
The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.
【1】What does the author say about the threat of robots?
A.It may constitute a challenge to computer programmers.
B.It accompanies all machinery involving high technology.
C.It can be avoided if human values are translated into their language.
D.It has become an inevitable peril as technology gets more sophisticated.
【2】What would we think of a person who invades our personal space according to the author?
A.They are aggressive. B.They are outgoing.
C.They are ignorant. D.They are ill-bred.
【3】How do robots learn human values?
A.By interacting with humans in everyday life situations.
B.By following the daily routines of civilized human beings.
C.By picking up patterns from massive data on human behavior.
D.By imitating the behavior of property brought-up human beings.
【4】What will a well-programmed robot do when facing an unusual situation?
A.Keep a distance from possible dangers. B.Stop to seek advice from a human being.
C.Trigger its built-in alarm system at once. D.Do sufficient testing before taking action.
23、I have a special place in my heart for libraries. I have for as long as I can remember. I was always an enthusiastic reader, sometimes reading up to three books a day as a child. Stories were like air to me and while other kids played ball or went to parties, I lived out adventures through the books I checked out from the library.
My first job was working at the Ukiah Library when I was 16 years old .It was a dream job and I did everything from shelving books to reading to the children for story time.
As I grew older and became a mother, the library took on a new place and an added meaning in my life. I had several children and books were our main source(来源) of entertainment. It was a big deal for us to load up and go to the local library, where my kids could pick out books to read or books they wanted me to read to them.
I always read ,using different voices ,as though I were acting out the stories with my voice and they loved it !It was a special time to bond with my children and it filled them with the wonderment of books .
Now, I see my children taking their children to the library and I love that the excitement of going to the library lives on form generation to generation.
As a novelist, I’ve found a new relationship with libraries. I encourage readers to go to their local library when they can’t afford to purchase a book. I see libraries as a safe haven(避风港) for readers and writers, a bridge that helps put together a reader with a book. Libraries, in their own way, help fight book piracy(盗版行为) and 1 think all writers should support libraries in a significant way when they can. Encourage readers to use the library. Share library announcements on your social media. Frequent them and talk about them when you can.
【1】Which word best describes the author’s relationship with books as a child?
A.Cooperative.
B.Uneasy.
C.Inseparable.
D.Casual.
【2】What does the underlined phrase “an added meaning” in paragraph 3 refer to?
A.Pleasure from working in the library.
B.Joy of reading passed on in the family.
C.Wonderment from acting out the stories.
D.A closer bond developed with the readers.
【3】What does the author call on other writers to do?
A.Sponsor book fairs.
B.Write for social media.
C.Support libraries.
D.Purchase her novels.
【4】Which can be a suitable title for the text?
A.Reading: A Source of Knowledge
B.My Idea about writing
C.Library: A Haven for the Young
D.My Love of the Library
24、 Chinese scientists applied a specially developed new technology to laser-ranging (激光测距) telescopes, which enabled them to identify space waste more effectively than previous techniques, according to a study published in the Journal of Laser Applications. “After improving the pointing accuracy of the telescope through a neural (神经的) network , space debris (碎片) with a cross sectional area of one square meter ( 10 square feet) and a distance of 1 ,500 kilometers (932 miles ) can be identified," Tianming Ma, an author of the study from the Chinese Academy of Surveying and Mapping, Beijing and Liaoning Technical University, Fuxin, said in a statement.
Debris can include non-functional spacecraft, abandoned launch vehicle stages, and other mission-related space waste. It is very dangerous for astronauts and spacecraft in orbit above the Earth as they travel very fast — up to 18,000 miles per hour. Worryingly, there are probably many millions of tiny debris pieces in low-Earth orbit, and tens of thousands larger than a softball, NASA said. Fortunately, there have been surprisingly few collisions.
Laser-ranging technology has previously been used to find space waste. However, these systems have their limitations when it comes to accurately identifying small, fast-moving pieces. In fact, previous laser-ranging methods have only been accurate to within about 0. 6miles.
In an attempt to overcome the inaccuracies in laser-ranging techniques, the Chinese team used so-called neural networks to improve the effectiveness of their telescope system. Neural networks are computing systems which are inspired by biological networks in the brain. They can learn to become better at tasks without being given a specific set of rules to follow. Ma and his team tested this method against more traditional techniques at the Beijing Fangshen laser range telescope station. According to the team, this is the first time that neural network has been used to significantly improve the pointing accuracy of a laser-ranging telescope. They say that the latest findings could have significant meaning for guiding spacecraft in orbit.
【1】What are laser-ranging telescopes designed to do?
A.Set up a neural network in space.
B.Find out the precise position of space waste.
C.Help the telescopes work more accurately.
D.Confirm the amount and size of space waste.
【2】Which can be regarded as space debris according to the text?
A.Useless man-made objects in space.
B.Fast-travelling softballs.
C.Launch vehicle stages in low-Earth orbit.
D.Satellites moving too fast.
【3】What can be used to describe the function of neural networks?
A.Rule followers.
B.Biological computing.
C.Machine learning.
D.Spacecraft guidance
【4】What can be the best title of the text?
A.New Technology Used to Find Space Waste
B.The First Telescope to Handle Space Debris
C.An Invention for Astronauts and Spacecraft
D.The Substitute for Laser-ranging Telescopes
