You know that eating healthy, staying active, and solving a few brain games can help keep your memory. But the following lesser-known habits work wonders too.
1. 1.
When we sit with our shoulders bent forward, this defeated position actually causes us to feel anxious or depressed — which makes it harder to think clearly and remember things. Conversely (反过来), straight upright posture apparently improves memory because it boosts blood and oxygen flow to the brain.
2. Exercise — Once
Having trouble remembering faces? 2. In a study, pictures of faces were shown to
older folks after they pedal a stationary (静止的) bike at an intense pace or simply sit on a self-pedaling bike. On average, people remembered the faces better after the intense exercise. What’s more, the memory gains after a single workout were similar to the gains after 3 months of regular exercise.
3. Limit TV
Every parent and grandparent has heard that too much screen time can hurt a child’s
cognitive development. 3. According to a study, people (aged 50 or older) who watched
more than 3.5 hours of TV a day for 6 years experienced a greater drop in verbal memory test scores than those who watched less.
4. Draw aimlessly
A research shows those who drew the words remembered the most when recalling words. That’s because while some parts of the brain about getting memory back become worse as people
grow older, the picture processing regions usually don’t. 4.
5. Walk Backward
5. Walk back! Backward motion — whether real, imagined, or watched — helps people remember the information better than sitting still and, in most cases, better than forward motion. It may be that moving backward in space mentally helps us move back in time to the moment we learned something.
A.Sit Tall.
B.Stand Straight.
C.Start more workouts.
D.Sweat for physical training.
E.Thus sketching can help adults keep their memory sharp.
F.But what about those at the other end of their life span?
G.Next time you’re trying to recall something, don’t just think back.
East Africa is experiencing the worst desert locust outbreak in decades. Climate events have accelerated breeding of the pest across the region, and with a sudden rise in the locust population expected in coming weeks, urgent actions and funds are needed to prevent a human crisis.
Twenty million people in six of the eight East African countries are most affected by an ongoing desert locust outbreak at risk of serious food insecurity. Considered among the most destructive of moving pests, an adult locust can consume 2g of plants per day, affecting crops and grasslands. A group typically holds 20 to 150 million locusts per square kilometer and can move hundreds of kilometers per day, invading areas covering millions of square kilometers. An active group, therefore, can destroy crops and grasslands within a very short period of time.
That global warming could increase the risk of desert locust crisis was proposed over ten years ago, and in February, the UN Secretary-General António Guterres stated that the current outbreak is linked to the effects of climate change: “warmer seas mean more perfect breeding ground for locusts”. The outbreak has its origins in 2018, when a series of windstorms in the Arabian Peninsula (阿拉伯半岛) enabled the warm and wet conditions the desert locust requires to breed and band undetected in remote regions. Though our focus here is migration west, dreadful outbreaks of the desert locust have been experienced to the east.
The situation is going out of control. A rescue operation and financial support admit no delay.
The Food and Agricultural Organization (FAO) can take out only US$138 million for rapid response and immediate action — controlling the spread of the desert locust and safeguarding livelihoods. They say the maths is clear: about half the funding (资助) is needed for supervision, ground and sky control, and uniting efforts; the other half is needed for livelihoods and food security of farmers. As for the huge gap, they have called on the international community to act now through funding. However, by the end of February, just US$69 million had been promised.
This most alarming crisis has developed and is worsening in East Africa. The funds needed to control the situation become very difficult to achieve and the gap is a big concern.
1.Why does the crisis happen in East Africa?
A.There is a big population there.
B.There are large deserts and grasslands.
C.Africa lies west of Arabian Peninsula.
D.Good climate for breeding plays a role.
2.Why does the writer list those figures in Para 2?
A.To warn of the terrible damage by locusts.
B.To help us understand how locusts live.
C.To show how many locusts there are now.
D.To draw a picture of the present Africa.
3.What can we infer from the text?
A.The crisis is not noticed until recently.
B.More fund is needed to prevent the crisis.
C.The crisis has been the focus of the world.
D.Locusts are all from the Arabian Peninsula.
4.Which is the best title for the text?
A.Killing locusts before too late
B.Global warming, a world problem
C.Funding Gap for Locust Crisis
D.Africa, a crisis-stricken place
Pinocchio may be just a children’s fairy tale, but Spanish scientists at the University of Granada recently investigated this so-called “Pinocchio effect” and found that our noses don’t grow when we tell a lie, but actually shrink a bit.
Dr. Gómez Milán and his team developed a lie detector test that used thermography（体温计）to tell if people were lying, and found that whenever participants in their research were being untruthful, the temperature of the tip of their nose dropped up to 1.2℃, while the temperature of their forehead increased up to 1.5℃. Scientist also found that drop in temperature at nose level actually caused it to slightly shrink, although the difference is undetected by the human eye.
“One has to think in order to lie, which rises the temperature of the forehead,” Dr. Gómez Milán explained the findings. “At the same time we feel anxious, which lowers the temperature of the nose.”
For this study, researchers asked a number of 60 students to perform various tasks while their temperature is scanned by technology. One of these tasks required making a 3 to 4 minutes call to their parents or a friend and telling a significant lie. Participants had to make up the lie themselves during the call. Interestingly, this lie detector picked up the “Pinocchio effect” temperature difference in 80 percent of the test subjects, which is a better rate of success than that of any modern lie detector.
“With this method we have achieved to increase accuracy”, said Dr. Gómez Milán, who added that law enforcement interviewers could one day combine other lie detection technology with thermal imaging to achieve better results.
1.Why does the writer talk about Pinocchio in the first paragraph?
A.To tell a fairy tale. B.To give an example.
C.To talk about a scientist. D.To introduce the topic.
2.What is “Pinocchio effect”?
A.Our noses will grow when we tell a lie.
B.Our noses will shrink when we tell a lie.
C.The temperature of the forehead falls if we lie.
D.The temperature of the student rises for anxiety.
3.How did Dr. Gómez Milán feel about the lie detector?
A.Doubtful. B.Surprised.
C.Confident. D.Puzzled.
4.What lesson can we learn from the text?
A.A lie will travel very hard. B.Many ways to bring a liar to light.
C.A lie never lives to be old. D.Once a liar always a liar.
Amanda Seyfried didn’t grow up with dogs. With her busy work schedule, she didn’t think she could take care of a dog. In fact, she wasn’t looking for a furry friend at all.
But then she met Finn. Today, the 34-year-old actress, who’s known for films Mamma Mia, is a dog owner and a spokeswoman at the welfare organization Best Friends Animal Society.
“I can’t imagine my life without him,” Seyfried says of 6.5-year-old Australian shepherd Finn, who is allowed on her U.S. set. If for some reason he can’t join Seyfried on location --- like on a recent trip when she traveled from France to China, Seyfried requests from her dog sitter twice — daily videos of him.
Now with a new video for Best Friends Animal Society, she calls herself Finn’s “stage mother.”
Seyfried and Finn shot an 80s-themed video for the 9000StepsChallenge, which asks animal owners to walk 9,000 steps with their pets on the ninth day of the month to raise awareness to the fact that more than 9,000 dogs and cats are euthanized (安乐死) in shelters each day because there’s not enough room.
As for the video shoot, in which Seyfried and Finn walked the 9,000 steps --- it was more exhausting than a long walk. Seyfried was Finn’s trainer on the shoot. She believes that instead of being Finn’s cp-star, she’ll go back to being BFFs.
1.Why did Seyfried originally refuse a pet dog?
A.She wasn’t not yet a spokeswoman.
B.She wasn’t used to being with a dog.
C.She was too busy to care for a dog.
D.She had not enough room for a dog.
2.Who does the underlined word “him” in paragraph 3 refer to?
A.Finn. B.Seyfried.
C.The dog sitter. D.Finn’s best friend.
3.Why did Seyfried shoot the video together with Finn?
A.To show how deep she loves Finn.
B.To train Finn to have a long walk.
C.To take part in an animal cp-star show.
D.To call on public attention to pets’ life.
4.Which section of a newspaper is this text most likely from?
A.News B.Life
C.Education D.Sports
