【题目】 Food companies engineer junk food to make it addictive. They label their products to make them seem much healthier than they are. Their advertisements target children. All of this is according to a news report read recently by students in a Texas middle school. They were taking part in an experiment run by the University of Chicago and the University of Texas. “I don't understand how this is even legal, ” said a girl who took part in the study.

Researchers had students learn about food-industry advertising strategies. They wanted to know if learning about them would change how kids feel about junk food. All over the world, kids are eating more foods that are high in salt, sugar, and fat. That is partly the result of clever ads that make junk food irresistible. Christopher J. Bryan led the study. He says that when kids question the motives behind junk food ads, they feel like they're fighting injustice. The reward is knowing they are doing the right thing.

Junk food has been linked to health problems such as heart disease, obesity, and diabetesBut in 2018food companies spent nearly $9 billion TV ads selling unhealthy fare. Companies use varying strategies. An ad with cartoon characters may make chips seen fun to eat. A professional athlete enjoying a sugary drink may make it look cool. Advertisers know that if kids want a product, they'll annoy their parents to buy it. Even parents don't notice the power of ads. By the time they are adults they have been used to junk-food advertising. They just don't see it.

In the Texas study, Bryan had students view ads on iPad. Their job was to write or draw on the screen, to make each ad's message true. For example, a McDonald's ad showed a Big Mac (巨无霸) and the words “The thing you want when you order salad. ” To the end of the sentence, a student added “should be salad”.

Three months after analyzing ads, students were still choosing healthier snacks: milk instead of sugary juices, fruit over cookies. Kids are becoming conscious of themselves as agents in the world. They see a chance to make the world a better place.

1What is the purpose of the experiment?

A.To survey what snacks children like best.B.To guide children against unhealthy food.

C.To find ways to make junk food healthy.D.To teach children how to pick out legal food.

2How do children feel about junk food advertisements after the experiment?

A.Cool.B.Legal.

C.Funny.D.Misleading.

3Why are parents unaware of the harm of junk food advertisements?

A.Parents have never seen such junk food advertisements.

B.Advertisements have blinded them since they were young.

C.The food industry has special advertising strategies for parents.

D.Parents have to agree with their children about the junk food.

4How did students conduct the experiment?

A.By correcting unreal advertisements.B.By offering suggestions to food industry.

C.By making up their own advertisements.D.By studying food industry advertising strategies.

【题目】 Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or e-DNA for short. Scientists can use it to identify rare species or estimate fish populations with just a little air or water.

Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature.

Caren Goldberg is one of the first biologists in the northwestern United States to take the technology from the testing stage to actually using it. She sees e-DNA as a way to get answers more efficiently, and with less destruction compared to traditional survey techniques. Until recently, scientists depended on diving deep, netting or using an electric current to temporarily catch fish.

This newer way to identify what lives in the environment is becoming popular around the world. Animal experts in Vietnam are using the e-DNA to find the last, wild Yangtze giant softshell turtles. One researcher on the Caribbean island of Trinidad is using the sampling technology to find endangered golden tree-frogs. And in Madagascar, it is being used to identify amphibian (两栖动物) diseases.

Ms. Goldberg has used e-DNA testing to confirm the local extinction of a leopard frog in the American state of Idaho. She has also been asked to document the spread of the New Zealand mud-snail in the state of Washington. The creature has been found in lakes and other waterways across the state.

Scientists working with the technology say they do not expect robots to replace field biologists anytime soon. But the old-fashioned field work could soon be more targeted.

1By using e-DNA, Caren Goldberg has ________.

A.succeeded in catching many fishes.

B.found the existence of golden treefrogs.

C.documented the spread of softshell turtles.

D.proved the disappearance of the leopard frog in Idaho.

2What can we infer from the last paragraph?

A.Robots will replace scientists soon.

B.Some scientists are against using e-DNA.

C.The old-fashioned field work may disappear.

D.Many biologists are unwilling to do the field work.

3The passage can be sorted as a(n) ________.

A.science fictionB.experiment report

C.science reportD.bio-diversity discovery

【题目】 As you get older, your memory declines, and constant stress and unhealthy lifestyles can also cause it to decline too soon. Even memory strategies won’t save you if you don’t know how to keep a good memory. 1 The following can be tried.

Exercise regularly

That’s right, we mean physical exercise. Leading a lifestyle spending a lot of time sitting down and not moving can also lead to memory loss. 2 It’s healthy for both your mind and your body.

Play video games

Yes, you heard us. Get on that controller and spend a couple of hours playing your favorite video game.3 A recent study illustrated how these pastimes can help improve the functioning of various memory-associated regions in the brain. But don’t go overboard, too much of a good thing can be bad for you.

Eat your vegetables

This is a no-brainer since it’s a well-known fact eating vegetables can help keep you and your body healthy, and that includes your brain. Various research papers state that fruits and vegetables can help lower oxidative (氧化的) stress in your brain. 4

Reduce stress level

5 Intense and persistent stress, especially at high levels, can easily impair our memory and disrupt our cognitive skills. You can do this by meditating, taking a walk or by taking mindfulness-based stress reduction methods.

A.It’s sometimes good for your mind.

B.Sharpen your brain with advanced devices.

C.Go ahead and practice whenever possible.

D.So go outside and start working up a good sweat.

【题目】 A trip to the theater, museum or art gallery could help you live longer. And the more often you get that culture fix the better, a new study suggests.

Researchers from University College London (UCL) found that people who engaged in the arts more frequently—every few months or more—had a 31% lower risk of dying early when compared to those who didn’t. Even going to the theater or museum once or twice a year was linked with a 14% lower risk.

“While other health behaviors like smoking, alcohol and exercise are undoubtedly bigger predictors of death rate, these leisure and pleasure activities that people don’t think as a health related activity do support good health and longevity.” said Daisy Fancourt, an associate professor at UCL’s Research Department of Behavioural Science and Health.

The study looked at a range of economic, health and social factors to try and explain why there is a link between “arts engagement” and living longer, although as an observational study it can’t establish cause. Part of the reason, the study said, comes down to social and economic differences among those who go and don’t go to museums, exhibitions and art galleries.

Wealth, they found, explained about 9% of the association. Cognitive differences, social and civic engagement, mental health, mobility and deprivation also played a role. Things like free time and occupational status made no material difference.

The study says that engaging with the arts can reduce stress and build creativity that allows people to adapt to changing circumstances. It also helps people build social capital—accessing emotional support and information that helps people age more successfully.

Everyone should have the chance to take part in cultural activities and the study added weight to growing concerns about the decline in arts subjects in schools and universities.

B.Social status plays an important role in leading a happy life.

C.Everyone taking part in art related activities can live longer.

D.There should be more arts subjects in schools and universities.
