21、Experts have long debated the best diet for health. They believe that it's not just what we eat that's important for good health but when we eat. When our diet pattern matches the biological clock well, our body can work at its best. Breaking the rule—by eating late meals or having night snacks—could lead to weight gain and metabolic (新陈代谢) trouble.
Many people, however, eat from roughly the time when they wake up until shortly before they go to bed. Studies show that the average person starts with something like milk and coffee shortly after rising and ends with a glass of wine, a late-night meal or a handful of chips, nuts or some other snacks shortly before bed. That pattern of eating is against our biological rule.
Scientists have long known that the human body has a master clock in the brain, which controls our sleep-wake cycles in response to bright light exposure (暴露). A couple of decades ago, researchers discovered that there is not just one clock in the body but a collection of them. Every organ has a clock that controls its daily cycle of activities. Studies show that in every organ, thousands of genes (基因) are turned on and turned off at roughly the same time every day.
We've lived on this planet for thousands of years, and while many things have changed, there has always been one unchanged: Every single day the sun rises and at night it falls. We're designed to have 24-hour patterns in our body. These patterns exist because, just like our brains need to go to sleep each night to repair and reset themselves, every organ needs to have time to repair and reset itself as well.
【1】What should we do according to paragraph 1?
A．Don't eat too much.
B．Try to lose weight.
C．Have a low-fat and low-sugar diet.
D．Have early meals for the night.
【2】What is the main idea of the second paragraph?
A．Eating Behaviors against the biological clock.
B．People's preference for a balanced diet.
C．Lifestyle of an ordinary busy person.
D．People's healthy eating habits.
【3】What do we know about the clocks in our body?
A．They are in our brains.
B．They control activities of each organ.
C．They are influenced by what we eat.
D．One clock control the other clocks.
【4】What is the best title of the text?
A．Select the Best Diet Habit
B．Reset the Clocks in Your Body
C．Choose a proper time to eat
D．Be Careful of Your Eating
22、Humans are fascinated by the source of their failings and virtues. This preoccupation inevitably leads to an old debate: whether nature or nurture (养育) shapes us more. A revolution in genetics has poised this as a modern political question about the character of our society: if personalities are hard-wired into our genes, what can governments do to help us? It feels morally questionable, yet claims of genetic selection by intelligence are making headlines.
This is down to “hereditarian” (遗传论的) science and a recent paper claimed “differences in exam performance between pupils attending extraordinary and ordinary schools mirror the genetic differences between them”. With such an assertion, the work was predictably greeted by a lot of absurd claims about “genetics determining academic success”. What the research revealed was the rather less surprising result: the educational benefits of extraordinary schools largely disappear once pupils’ inborn ability and socio-economic background were taken into account. That is to say, there’s nothing to support strongly either a hereditary or environmental argument.
Yet the paper does say children are “unintentionally genetically selected” by the school system. Central to hereditarian science is a tall claim: that identifiable variations in genetic sequences can predict an individual’s ability to learn, reason and solve problems. This is problematic on many levels. A teacher could not seriously tell a parent their child has a low genetic tendency to study when external factors clearly exist. Unlike-minded academics say the inheritability of human traits is scientifically unsound. At best there is a weak statistical association and not a causal link between DNA and intelligence. Yet sophisticated statistics are used to create a frightening atmosphere of scientific certainty.
While there’s an undoubted genetic basis to individual difference, it is wrong to think that socially defined groups can be genetically accounted for. The fixation on genes as destiny is surely false too. Medical predictability can rarely be based on DNA alone; the environment matters too. Something as complex as intellect is likely to be affected by many factors beyond genes. If hereditarians want to advance their cause it will require more balanced interpretation and not just acts of advocacy. Genetic selection is a way of exerting influence over others, “the ultimate collective control of human destinies,” as writer H. G. Wells put it. Knowledge becomes power and power requires a sense of responsibility. In understanding cognitive (认知的) ability, we must not elevate discrimination to a science: allowing people to climb the ladder of life only as far as their cells might suggest. This will need a more skeptical eye on the science. As technology progresses, we all have a duty to make sure that we shape a future that we would want to find ourselves in.
【1】What did a recent research paper claim?
A．The type of school students attend makes a difference to their future.
B．Genetic differences between students are far greater than supposed.
C．Students’ academic performance is somewhat determined by their genes.
D．The advantages of extraordinary schools are too obvious to ignore.

23、The outbreak of locusts, an insect that mainly lives in Africa and Asia, is the worst experienced by Kenya in 70 years. The crowds are some three times the size of New York City, eating their way through thousands of acres of crops and animal grassland and destroying livelihoods in the process.
“These hungry things are alarming,” says Keith Cressman, the UN Food and Agriculture Organization's senior locust forecasting officer. "A crowd the size of Manhattan can, in a single day, eat the same amount of food as everyone in New York and California combined."
Desert locusts are infamous for their ability to breed(繁育)rapidly in large numbers every three months. And with some help from the wind, they can travel as much as 80 miles a day. Most years, the insects stay in African deserts. However, under the right environmental conditions, they can multiply quickly, spread as much as 400 times every six months and cause extensive destruction if left unchecked.
“The insect has the ability to take advantage of good conditions.” Cressman says.
The "good conditions" the scientist is referring to began in mid-2018 when a rainstorm from the Indian Ocean struck a remote area of the Arabian Peninsula known as the "Empty Quarter". Normally, it would dry out within a short period, killing most of the locust population, which depends on green plants for food. However, in late 2018, a second rainstorm struck the same region. The huge sandy area got wet, which is exactly what desert locusts need to lay their eggs and breed. The extra food supply caused the population to explode for the second time in six months.
Luckily, the locusts, experts say, are easy to control with chemicals. Kenya badly needs equipment and a steady supply of chemicals to effectively wipe out the massive insects. Hopefully, leaders worldwide will recognize the tough situation and contribute generously to control the locust outbreak.
【1】What can we infer from what Cressman says in paragraph 2?
A．Little can dull locusts' appetite.
B．Urgent action must be taken against locusts.
C．Overpopulation in big cities leads to food shortages.
D．New York and California should meet challenges together.
【2】What is paragraph 3 mainly about?
A．Locusts' living conditions.
B．Locusts' destructive effect.
C．Locusts' daily travel distance.
D．Locusts' super reproductive power.
【3】For what purpose does the author mention "good conditions"?
A．To explain immediate causes of the locust outbreak.
B．To remind locals to preserve the environment.
C．To analyze how to prevent locust outbreak.
D．To highlight the strength of two rainstorms.
24、Global GDP in 2030 will be 14% higher as a result of AI(Artificial Intelligence), thanks to improving labor productivity and increasing consumer demand, says a report.
The report could increase the enthusiasm of economic policymakers and the public, and show the power of technology in changing not only people’s daily lives, but also economic activities. However, history tells us that, while technological advancements have brought us benefits, they have also led to great social disorders, by changing the production and labor structures, and forcing many workers to either adapt to the changes or lose their jobs. In the 18th century, for instance, skilled workers rose up to resist the Industrial Revolution, destroying machinery in the early 19th century. We may not see similar protests today, but history should serve as a warning against the application of AI technology.
While we may gain a lot of benefits from AI, we must work out plans to reduce its negative effect on society, especially for workers. AI can raise productivity and expand GDP, but it can also make non-adaptive workers jobless. In India, some technology personnel have already felt the negative effect of information technology. As technology industries across the world seek increasing support from automation（自动操作）, robotics and big data analysis, some technology workers have already lost their jobs.
In their 2013 research study, Michael Osborne and Carl Frey from Oxford University estimated 47% of the jobs in the United States are “at risk” of being automated in the next 20 years. They said jobs in transportation and office and administrative support are at high risk of being automated. And Kaifu Lee recently said that robots could take away about 50% of all jobs from humans in the next decade.
Those estimates may sound sensational and the impact of technological advancements may not be that serious, as they will also create jobs in new industries. However, policymakers should consider how to better embrace the technological wave to bring benefits while taking action to minimize its negative effects. The government therefore needs to work together with business leaders and social organizations, to promote training programs for potentially helpless workers, in order to make them more capable of adapting to the structural changes in industries and job markets in the future.
【1】Paragraph 2 mainly wants to tell us that technological advancements have ________.
A. brought us a lot of benefits B. improved our daily lives
C. caused some social problems D. led to great unemployment
【2】We can learn from the passage that ________.
A. the government should discover people’s potentials
B. technology workers are more likely to survive AI technology
C. we should take action to meet the challenge of the AI technology
D. most workers are willing to accept the changes brought by AI technology
【3】The underlined word “sensational” in the last paragraph probably means______.
A. shocking B. powerful
C. inspiring D. wonderful
【4】The passage is intended to ________.
A. warn us against the negative effects of AI technology
B. present the good and bad effects of AI technology
C. inform us of the development of AI technology
D. arouse people’s enthusiasm for AI technology
