21、Losing ourselves in the chaos of daily life has become a lot more common for so many people around the world. So people often ignore an important thing — healthy eating habits. This can lead to weight gain and even physical and mental illness. 【1】, we highly recommend mindful eating.
Eating with your non-dominant hand is a great way to stop you from overeating. 【2】, it’ll force you to slow down and thus allow you to be a lot more conscious of the food you are eating. It’s also an effective way for those wanting to lose weight.
It’s so common for people to eat on the move between their busy schedules. This is never a good eating habit. Yet many of us still do it. Eating on the run and swallowing food without chewing it well can result in indigestion. 【3】
When it comes to eating, you should give your undivided attention to the food you eat, which means you should turn off any electronic devices. 【4】. Technological devices should not be a distraction from any mindful eating practices. So while eating, be sure the TV is off and keep away from your cellphone.
【5】. Sometimes, you rush through the day and only eat when the opportunity arises. Always make sure you are on a chair while eating your meals; otherwise you are less likely to truly appreciate the food on your plate. One part of mindful eating is about doing nothing else while you’re eating.
A．Don’t multitask while sleeping
B．You should sit down and eat
C．You’re accustomed to moving
D．As this isn’t something the brain is used to
E．Chew each bite of food up to 30 times before swallowing
F．This tip applies to nearly everyone in this day and age
G．In order to fight against these problems
22、Getting old might not be something that's yet to cross your mind. But ageing is inevitably going to get the better of us one day, so it's something I'm sure we'd all like to control. It would be great to have a long, healthy and happy life, and that's why scientists are constantly seeking out evidence that will show us what we need to do to achieve longevity.
We all know that regular exercise is good for us. In recent years we've been told to aim to walk 10,000 steps a day to remain healthy, although other advice to do three brief 10-minute walks a day is thought to be even more effective. But the latest piece of research might put a spring in your step if you're someone who walks at a slow pace. That's because, according to scientists, the speed at which people walk in their 40s is a sign of how much their brains, as well as their bodies, are ageing.
The BBC's Philippa Roxby writes that tests on 1,000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of “accelerated ageing”: their lungs, teeth and immune systems were in worse shape than those who walked faster. And to add insult to injury, the study found not only did slower walkers' bodies age more quickly, their faces looked older and they had smaller brains. Professor Terrie E Moffitt, lead author of the study, told the BBC, “It found that a slow walk is a problem sign decades before old age”.
This might be seen as a wake - up call for people with a slower pace who might feel it's time to work out and get fitter. But it might be too late; researchers writing in JAMA Network Open say they were able to predict the walking speed of 45 - year- olds using the results of intelligence, language and motor skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will go on to have a healthier life.
So, what's the point of knowing that a slower walking pace might mean a smaller brain? Well, researchers say measuring walking speed at a younger age, and understanding what this might mean, could be a way of testing treatments to slow human ageing. This might help us make lifestyle changes while we're still young and healthy. Taking steps to prolong a good mental and physical state is a no brainer!
【1】The underlined part in paragraph 2 is closest in meaning to______________.
A．accelerate your pace
B．withdraw your footsteps
C．decrease your walking speed
D．mind your step
【2】What can be learned from the study by Philippa Roxby and Terrie E Moffitt?
A．Due to increased ageing problem, people become less physically healthy which leads to their slower walking.
B．When people choose to walk fast, they tend to look younger than when they choose to walk slowly.
C．People with small brains walk more slowly than those with big brains.
D．Slow walking can be probably used to predict aging problem decades before one grows old.
【3】What can we infer from the passage?
A．If one walks slowly, there's no chance that he will live a long life.
B．By checking one's walking speed at a young age, we can prevent fast aging from happening.
C．We will definitely try to find ways to make our healthy state last longer
D．The outcomes of people's IQ tests can provide information for us to foresee one's walking speed.
【4】What is the best title of the passage?
A．Researches on Slow Walking
B．Slow Walking VS Fast Walking
C．Why Slow Walking ages us
D．Slow Walking and Ageing
23、As it turns out, comfort food, instead of comforting you, may actually be linked to your mental comfort but cause you to become depressed. One of the main reasons for eating junk food is stress eating, but now new research has also suggested it's harming your mental health too.
Junk food, fast food and so-called “healthy snack options” are all big business nowadays because they provide convenient options for people on the go. The decision when choosing a snack of going for what you want, over what you need, plays an important part in your overall mental health.
Researchers at Cardiff University believe that reaching for unhealthy snacks when the stress of time-sensitive commitments, such as work or study, limits your choices of snacks, won’t only destroy your fitness goals, but it can also negatively affect your mental health.
Scientists provided crisps, chocolate or a piece of fresh fruit to test subjects before measuring their effects on mental comfort. The results were amazing. Those snacking on crisps and chocolate showed greater symptoms(症状) of depression, anger and emotional disorders in only 10 days. The increase was an unbelievable 47% in depressive parts. The subjects that snacked on fruit experienced none of these symptoms. In fact, on the contrary, they became 32% less anxious.
While the researchers didn't point out exactly why the fruit group felt so much happier, the answer may lie in fruit’s ability to increase the brain’s production of serotonin, which is commonly known as a feel-good neurotransmitter(神经递质) that can help to bring about a happier state of mind and reduce anxiety.
The best results you can take away from the study is that when you’re hungry you should always be well prepared with healthy snacks that will not only fill you up but will also positively affect your mental health and keep you focused all day long.
【1】The underlined part “comfort food” in the first paragraph probably refers to “________”.
A．tasty food
B．junk food

【2】Why do people prefer snacks nowadays?
A．They are always very busy.
B．They like their delicious tastes.
C．They have no other good choices.
D．They need to improve their mental health.
【3】Which will you choose for mental health according to the research?
A．Pineapples.
B．Candies.
C．French fries.
D．Chocolate.
【4】What can be the best title for the passage?
A．How to choose healthy food?
B．Are snacks harmful to health?
C．Is comfort food really comforting?
D．What's the best choice for pressure relief?
24、Thousands of emperor penguins pack together on the ice of Atka Bay in Antarctica, mostly unaware that among them lives a 3-foot-tall autonomous robot called ECHO. The birds occasionally notice the unmanned and remote controlled ground vehicle out of curiosity but quickly move on from the object, which acts like a mobile antenna(天线)for an observatory monitoring about 300 of them each year.
Penguins dominate the South Pole, but the climate crisis could threaten their very existence. A study published last year reported 98% of the emperor penguin population could all but disappear by 2100 due to the impact of climate crisis in Antarctica. “As top predators, emperor penguins serve as ideal species to study in an unsteady ecosystem,” said Zitterbart, associate scientist at the Woods Hole Oceanographic Institution.
Surprisingly little is known about these penguins because Antarctica isn’t the easiest place for scientists to access. Although it’s crucial to learn more about the penguins and their ecosystem, Zitterbart and his team didn’t want to introduce a harmful human footprint in an already vulnerable environment or negatively affect the colony.
A successful trial run of ECHO this year is already showing how that may be possible.
Since 2017, Zitterbart and other researchers have been tagging 300 penguin chicks with a system similar to how dogs and cats are microchipped. But the small sensors worn by the penguins don’t have their own power supply, so they can only be read from about a meter or two away.
That’s where ECHO comes in. The robot acts like a receiving station with wireless receivers, automatically collecting data from the penguins’ sensors. With ECHO, the researchers don’t miss out on a chance to collect data when the birds return to the colony to feed their chicks and no longer have to search through a crowd of 20,000 birds to find the tagged ones because ECHO picks up on them automatically.
Tracking the penguins allows the team to determine where the penguins go when they dive off the sea ice into the ocean and understand their food hunting strategies. “In the next stage, we will extend ECHO’s data collection to include penguins’ reproductive behaviors that scientists haven’t been able to collect before,” said Zitterbart.
【1】What’s emperor penguins’ reaction to ECHO?
A．Defensive
B．Frightened.
C．Undisturbed.
D．Unfriendly.
【2】What does “that” in paragraph 4 refer to?
A．Cutting carbon dioxide emission in Antarctica.
B．Studying penguins without polluting the land.
C．Having access to more knowledge about Antarctica.
D．Involving more scientists in studying emperor penguins.
【3】What is the team likely to study about emperor penguins in the future?
A．How they produce young.
B．Where they search for food.
C．When they dive into the deep sea.
D．Why they can survive the extreme cold.
【4】What can be the best title for the text?
A．Emperor penguins are dying out.
B．Uncover more mystery of penguins.
C．Technology brings life back to Antarctica.
D．Meet the robot in the Antarctic penguin colony.
