1 . Here is a story about a young boy in New York. He once went to one of Dr. Jane Goodall’s talks and learned about the _______ expressions of chimpanzees.

When he saw a picture of a chimpanzee on a box of _______and it looked like the chimpanzee was grinning (咧嘴笑), the boy _______ from what he’d learned at Dr. Goodall’s talk that the chimpanzee’s look was actually one of _______.

The boy _______ to the cookie-maker asking to take the chimpanzee’s picture off the box. _______ receiving a letter back from the company, he saw the picture of the chimpanzee _______from the box within just a few months.

“I took _______,” the boy now says. “And the company changed.”   _______ it happened that the picture changed, the boy and his family   ________it was his doing.

As the story shows, young students have much more ________ to accomplish change than what   ________may believe. Moreover, students often achieve much more than they ever   ________ they will.

The story also ________us that small actions can have a big impact. We often tend to think about   ________ events like Clean and Green Week. Instead, a lot of small changes can make a(an)   ________. If hundreds or thousands of students   ________ their families to turn off the tap to save water, move the air-conditioning temperature up a degree or two, drive less and make other environmentally friendly changes, the ________ family may change its behaviors.       

With these small yet highly   ________ changes, students have an effect beyond just their own actions. Students can   ________ by realizing that their own actions have more power than they may expect, and environmentalists can benefit as well by taking the time to focus on even the youngest students.

2 . Americans spend billions on vitamins, multivitamins for their health, but a review of numerous studies concluded there is little to no evidence that some of those vitamins prevent heart disease, cancer or death.

The report, released by the U.S. Preventive Services Task Force last week, concluded that “recent evidence is not enough” to determine whether vitamins actually help or hurt your health, based on 84 studies, 52 of which were done since 2014. Vitamins examined included vitamins A, B, C, D and E, as well as other multivitamins.

“Our suggestion is neither for nor against taking vitamins, or combinations of those nutrients (营养物质). We just don’t have enough evidence,” said Dr. John Wong, a doctor in the Department of Medicine at Tufts Medical Center who was involved in the report.

While the finding is that vitamins don’t have any benefits to “healthy, non-pregnant (未怀孕) adults”, it doesn’t apply to “children, people who are pregnant or may become pregnant, or people who are hospitalized.”

The Task Force admitted it makes sense that people would take vitamins in hopes of health benefits, as some shortage may lead to illness. But experts agreed the best way to get good health and prevent cancer is a balanced diet and regular physical activity.

“The suggestion across all organizations about vitamins is to eat a balanced diet, and then the key tends to be on plenty of fruit and vegetables and less junk foods,” Wong said.

Wong added people should refer to their health doctors to determine if any vitamins are worth taking. He said this suggestion should also serve as a need to further research into proving the official benefits and risks for each vitamin.

3 . Picture the scene: you’ve spent years working towards a very specific goal. You’ve put in countless hours of work and made many efforts along the way, but now that you’ve got there it doesn’t feel quite like you imagined. Instead of celebration, you feel emptiness, confusion and doubt.

Welcome to the anti-climax. The often-experienced but seldom-discussed downside of achieving life’s biggest milestones. Many of us work tirelessly towards our goals. We may spend our lives dreaming of the day we get married, publish our first hook or buy our first home. However, oftentimes, when we achieve these things it doesn’t feel quite as expected. In fact, the achievement of these goals feels a bit of a letdown.

So why do we often experience an anti-climax with big goals, even though we’re happy to achieve them? “An anti-climax can be an unexpected by-product of a milestone achievement. Usually, the more significant the milestone, the greater the anti-climax may be. The intensity（强度）of an anti-climax often relies on what we expect of this achievement.” says Rachel Vora. a psychotherapist（心理治疗师）.“The journey to achieving a milestone can he exciting and tiring in addition to giving us a sense of purpose and focus. Therefore, when this disappears overnight. we can often feel lost and confused, in spite of feeling proud of our achievement.

When this happens it can contribute to a mixture of emotions. We often falsely believe that we’ll feel completely different afterwards or that our feelings of low self-worth will disappear, but this is rarely the case. “Clients（客户）often present to me with an extremely great sense of ‘is this it?’ and ‘what now?’.” says Vora. “These feelings of confusion and disappointment, if let ignored, have the potential to cause clients to be in low spirits, or even worse.”

4 . The Myers-Briggs Type Indicator (MBTI) was invented by Katharine Cook Briggs and her daughter Isabel Briggs Myers. It is a self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. The MBTI personality inventory (量表) sorts people into 16 type categories, each of which is represented by four-letter codes such as INFP and ESTJ. Every year, about 1.5 million people have enjoyed discovering their personality type by completing the MBTI. Many companies, as well as hundreds of universities, use it in hiring and training.

Nevertheless, the MBTI has received a noticeable criticism from the academic community. Some research suggests the MBTI is unreliable because the same person can get different results when retaking the test. Other studies have questioned the validity of the MBTI, which is the ability of the test to accurately link the “types” to outcomes in the real world -for example, how well people classified as a certain type will perform in a given job.

Merve Emre, a professor a Oxford University, points out that it would be more scientifically advisable to score the MBTI scales continuously to show people the degree to which they resemble the types. Even when the MBTI’s results don’t quite match your intuition (直觉) about yourself or are just wrong, they can still provide self-insight and insight into differences and similarities between people.

Scoring and interpreting the MBTI the way other personality inventories are scored and interpreted might be less fun than finding. All of the folklore (民间看法) about INFPs, ESTJs, etc. would have to be dismissed. But, in the end the MBTI is sufficiently reliable and valid enough to be useful in a number of real-world contexts.

5 . How to Stop Spam Calls for Good

If you made a list of the little things that bothered you the most, phone call scams would no doubt be at the top. Telemarketers, or more often, automated robot-callers, have tricks for interrupting you at the worst possible moment.     1    

Fact is that robot-callers are never going to stop trying to reach you. Their schemes bring in hundreds of thousands — if not millions — of dollars annually. And unfortunately, older people are more likely to fall prey to these scams.     2    

Sign up for the National Do Not Call Registry

Your first move: Join the Federal Trade Commission’s National Do Not Call Registry. You can get on the list by calling 1-888-382-1222 from the phone number you want to register.     3     To date, the agency has taken 51 legal actions against companies and telemarketers, recovering $112 million.

Use spam-filtering apps and tech

    4     A spam-filtering app can give you a second layer of protection and is a good add-on to your overall smartphone security. The app’s makers maintain a large database of user-reported robocalls. When one of those numbers dials you, the app blocks the phone from ringing and informs you the call is spam. Genius!

    5    

You probably know that a caller who insists you owe money to the IRS or says you’ll be arrested if you don’t settle a debt is a scammer. But your 10-year-old kid and your older parents and grandparents may be tricked. And remember: Knowing how to stop spam calls is just one step toward avoiding scams; don’t forget to explain how to stop spam texts to your loved ones, too.

7 . Climate breakdown threatens to cause a global food production crisis. The UN forecasts that by 2050, feeding the world will require a 20% expansion in global water use for agriculture. It is hard to see how agriculture can feed the population of the planet, let alone toward the end of the century and beyond. Agriculture is a major cause of climate breakdown, and both river and air pollution. Industrial fishing is similarly driving ecological collapse in seas around the world.

However, at this critical time, farming (a new kind of food technology) is creating astonishing possibilities to save both people and the planet. Farming will enable the return of vast areas of land and sea to nature, greatly reducing carbon emissions (排放物). It means an end to the employment of animals, a stop to overfishing, and a dramatic reduction in cutting down forests and the use of pesticides (杀虫剂). It is the best hope for stopping the destruction of the planet and, if it is done right, it means cheap and abundant food for everyone.

We are about to welcome one of the biggest economic transformations, of any kind, for 200 years. Arguments continue about plants against meat-based diets; however, new technologies will soon make these arguments irrelevant. Before long, most food will come neither from animals nor plants, but from micro-organisms (微生物).

Not only will food be cheaper, it will also be healthier. Due to the fact that farming creates food products built up from simple components rather than broken down from complex ones, hard fats and other unhealthy components can be screened out. Meat will still be meat, but it will be grown in factories rather than in the bodies of animals. Fats will still be fats, but food is likely to be better, cheaper and much less damaging to the living planet.

With the International Conference on Food Loss and Waste closed on Saturday in Jinan, Shandong Province, the country has sent a signal to     1     world that China will deal with issues concerning food security by reducing loss and waste in agriculture. With the theme of reducing food loss and food waste and promoting     2     (globe) food security, the three-day event     3     (hold) both online and offline attracted more than 300 participants.

The current world grain production is about 2.8 billion tons a year. Therefore, the loss of only one percentage     4     (be) equal to the loss of 28 million tons of food. This can feed about 70 million people.

In recent years, China     5     (make) great progress in controlling loss and waste in food, with main efforts including upgrading facilities and     6     (equip). In Shandong Province, China’s major grain producer, the Sinograin (中粮集团) grain storage site is equipped with 4,500 high-definition cameras and 280,000 temperature sensors     7     (ensure) that the stock (储备) is in the best condition. Data shows that during China’s 13th Five-Year Plan period (2016-2020) , about 13 million tons of food had been saved     8     (year) after production.

We cannot end hunger     9     we do not deal with the high levels of food loss and waste. Cooperation and innovations (创新) in business models, technologies and digital solutions could all contribute     10     reducing food loss and waste.

An article describing the attitude of post-1990s generations toward life has     1     ( recent ) become popular on Chinese social media. By using the phrase “ Buddha-like   youngsters ”（佛系青年）, the author     2     ( show ) that some of the post-90s generations have seen through life and kept     3     casual and calm attitude toward life. “They have become more casual and cared     4     ( little ) about life’s choices.”

“It is fine to have something or not, there is no need to fight for or win anything, and they are easy     5     ( satisfy ),” says the article. A classic example is that Buddha-like youngsters do not care about     6     ( choose ) what to eat or where to spend a holiday.

The phrase has been received well by netizens    7     it was first created. The original Wechat post has been read more than one million     8     ( time ) and then read more than 60 million on Sina Weibo till now.     9     ( it ) sudden appearance and quick popularity show that the post-90s generations are under great pressure. “ We should pay attention     10    their needs and create a suitable environment for them to develop,” says Xu Hua, professor of the School of Sociology and Political Science of Anhui University.
