(2022·咸阳高二期中)We tend to think of plants as the furniture of the natural world. They don't move, they don't make sounds, they don't seem to respond to anything—at least not very quickly. But as is often the case, our human's view of the world misses quite a lot. Plants talk to each other all the time. And the language is chemical.
Over the years scientists have reported that different types of plants, from trees to tomatoes, release compounds (化合物) into the air to help neighbouring plants. These chemical warnings all have the same purpose—to spread information about one plant's disease or infestation (侵扰) so other plants can defend themselves. But exactly how plants receive and act on many of these signals is still mysterious.
In this week's Proceedings of the National Academy of Sciences, researchers in Japan offered some explanations. They had identified one chemical message and traced it all the way from release to action.
The scientists looked at tomato plants infested by a common pest, the cutworm. The researchers studied leaves from exposed and unexposed plants. They found one compound showed up more often in the exposed plants. The substance is called Hex Vic. When the scientists fed Hex Vic to cutworms, it knocked__down their survival rate by 17%. The scientists identified the source of Hex Vic, and sprayed it lightly over healthy plants. Those plants were then able to start producing the cutworm-killing Hex Vic. Researchers confirmed that uninfested plants have to build their own weapon to fight off bugs and diseases. How do they know when to play defense? They are warned first by their friendly plant neighbours.
It is a complex tale, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. For now though, we know that plants not only communicate, but they also look out for one another.
1．What does paragraph 1 intend to tell us?
A．How plants communicate is still a mystery.
B．Enough attention has been paid to plant talk.
C．Plants are the furniture of the natural world.
D．Plants can communicate with each other.
2．What is unknown according to paragraph 2?
A．How plants receive and handle the signals from their neighbours.
B．Why plants spread chemical information to their neighbours.
C．How many types of plants release compounds into the air.
D．Whether plants send chemical warnings to their neighbours.
3．What does the underlined phrase “knocked down” mean?
A．Hit.　　　　　　　　　        B．Increased.
C．Expanded.        D．Decreased.
4．What may be the best title for the passage?
A．Survival of Plants        B．Plant World
C．Talking Plants        D．Plant Bug killer

(2022·宝鸡高二期末)New research published in the journal BMJ Open Sport and Exercise Medicine indicates that men and younger adults have been less physically active during the COVID -19 lockdown.
The study, led by Anglia Ruskin University(ARU) and Ulster University, includes data from 911 UK adults who took part in an online survey which began on 17 March. The research found that 75% of UK adults had met the World Health Organization's physical activity recommendations of 150 minutes of middling physical activity or 75 minutes of vigorous (剧烈的) physical activity per week, since the introduction of social distancing regulations. This is higher than previous studies carried out before the COVID-19 pandemic, which found that between 58% and 66% of the UK adult population typically meet physical activity guidelines.
The new study found that women, older adults, and those with a higher annual house-hold income were significantly more likely to meet the WHO's physical activity guidelines. This is the opposite of studies carried out before the pandemic, where men and younger adults were found to have higher levels of physical activity.
Lead author Dr Lee Smith, reader in Physical Activity and Public Health at ARU, said, “The overall levels of physical activity are higher than we were expecting. It may be that the UK public have experienced an increase in free time and used this time to be physically active. Additionally, during the early stages, one of the few reasons to leave home was to take part in an hour of exercise. As well as offering a reason to go outside, this may have served as a target for some people.”
Typically, the proportion (比例) of UK adults meeting physical activity guidelines declines with age. Therefore, there should be additional support offered to older adults to encourage them to sustain this level of physical activity post pandemic.
5．How long does WHO recommend one exercise per week?
A．150 minutes of vigorous exercise.
B．2 hours of vigorous exercise.
C．2 hours and a half of medium exercise.
D．75 minutes of middling exercise.
6．Who performed better in meeting the guidelines during the COVID-19 lockdown?
A．Older adults.
B．Teenagers.
C．Younger adults.
D．Middle-aged men.
7．What is higher than expected behind the overall levels of exercise?
A．Higher income.
B．Added spare time.
C．Concern for health.
D．Better education.
8．What can we know from the last paragraph?
A．The less freedom one has, the more he works out.
B．The busier one gets, the more he works out.
C．The more one earns, the less he works out.
D．The older one becomes, the less he works out.
Ⅱ.七选五
I have just eaten a delicious conference pear weighing about 180g. I do not normally weigh snacks, but the recently reported health benefits of eating more fruit and vegetables have inspired me to dig out the scales.
A study published last month showed that, as expected, people who eat fruit and vegetables regularly cut their risk of dying from several diseases such as stroke, cancer and heart disease. 1.________
The data suggested that, compared with eating no fruits and vegetables, overall health outcomes improve with every 200g increment, up to 800g (up to 600g for those with cancer). Unsurprisingly, few people manage to eat more than 800g, meaning that scientists are unable to reliably investigate the benefits of higher intakes.
2．________ Eating 200g of fresh produce (about two and a half portions) appeared to cut the risk of cardiovascular disease by 13 percent, the risk of dying from cancer by 4 percent, and the risk of premature death by 15 percent. 3.________ There is a 28 percent reduction in the risk of cardiovascular disease; a 13 percent reduction in total cancer risk; and a 31 percent cut in the risk of premature death.
Some fruits and vegetables seemed especially protective for certain conditions. 4.________ Those wanting to avoid early death, particularly from stroke or heart disease, could add the following to their plates: apples, pears, oranges and leafy vegetables.
Dr Aune said that, even though further research was needed to pin down the details, “a high intake of fruit and vegetables holds tremendous health benefits, and we should try to increase their intake in our diet”. Whole plant foods beat processed versions such as smoothies, which can be high in sugar. 5.________ Dr Aune said there was no evidence that they cut the risk of disease.
Anyway, back to the scales. With each pear clocking in at nearly 200g, I did wonder whether I could gain my 800g with three more ripe beauties from the fruit bowl, currently siting by two wrinkly apples and an unappealing banana. My ugly fruit friends: your time has come.
A．Even so, modest amounts seem to make a difference.
B．Nutritional supplements are no substitute.
C．It adds weight to the idea that a healthy diet plays a role.
D．For cancer, the researchers suggested a possible benefit from green and yellow vegetables.
E．Upping daily intakes to 800g brings even better news.
F．Each of those studies had one thing in common.
G．Generally, the higher the intake of fruit and vegetables, the lower the risk.
