1 . Twelve grams of moon arrived at Ferl’s laboratory in an undecorated delivery box. Ferl, a gardening expert at the University of Florida, had waited more than a decade for that moment. The small box of dirt held some of the last remaining unopened samples of moon dust, called regolith, collected by astronauts on the lunar missions. Despite months of practice, he lifted the sample with trembling hands. “It’s freaky, scary stuff,” he says, “mean, what happens if you drop that?” Ferland his team were about to become the first researchers to grow plants in actual lunar soil.
The experiment was part of a lunar research which aims to send humans back to the moon later this decade in a more sustainable way. Longer duration stays require astronauts to have a source of food. “All of human exploration has been driven by the ability to keep crews fed,” says Gil, a researcher not involved in the study. And Ferl’s experiment offers a significant first step in this journey.
To test the moon soil, Ferl’s team divided the samples into 12 pots of 900 milligrams a piece and planted seeds in them. The seeds developed successfully, but the plants had trouble growing healthy roots. The moon soil lacks important microbes, which play a significant role in regulating plant growth hormones (激素), reducing environmental stress, and absorbing essential nutrients. Without natural microbes, the plants struggled to absorb nutrients and manage stress. Additionally, the lack of water can cause the soil to become difficult to work with.
The seedlings failed to grow strongly in regolith alone, but Ferl hopes to continue studying how life might take hold in otherwise low-yield soil, with an eye toward both boosting humanity’s prospects off the planet and improving agriculture in low-yield soils here at home. “Most of us are not going to go to space,” he says, “But if we can engineer a way to produce these kinds of crops in such an unforgiving environment — like the lunar surface — we can apply that to meet our food challenges in areas that just can’t grow food anymore.”

3 . Do you know Ikaria? It’s a beautiful island in Greece, which is named after Icarus, a young man in Greek mythology (神话) who flew too close to the sun and finally fell into the sea.
This island may look like any of the other Greek islands, but there is an important difference. People on Ikaria generally live on average ten years longer than those in the rest of Europe. According to studies, Ikarians have much lower rates of cancer and heart disease. They remain physically active and well into their nineties. Ikaria is one of the five so-called “Blue Zones”. It’s a name given to the five regions in the world where people live longer.
Scientists have expected to find out Ikarians’ secret to living longer over the last several years. One discovery is that Ikarians have a healthy diet, preferring simple and natural food. Besides, the midday rest here has been proven to improve the function of the heart. And Ikarians’ relaxing lifestyle and strong family and social ties also benefit their long life.

4 . Rome — Doctors and medical groups around the world last weekend reacted with strong opposition to the news that an Italian specialist is on the brink of cloning the first human baby.
Dr. Severino Antinori, who is the head of a hospital in Rome, has been referred to in an Arab newspaper as claiming that one of his patients is eight weeks pregnant (怀孕) with a cloned baby.
Antinori refused to comment on the reports, but in March 2001 he said he hoped to produce a cloned embryo (卵) for implantation within two years. So far seven different kinds of mammals have already successfully cloned, including sheep, cats and most recently rabbits.
Doctors showed their doubt and were strongly opposed although they admit that human cloning would finally come true unless there was a world wide ban on the practice.
Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology: “I find it astonishing that people do this where the result can be foretold that it will not be a normal baby. It is using humans as guinea pigs. It makes people feel sick.”
But Ronald Green, director of the Ethics Institute at Darmouth College in the US, said it is unlikely that an eight-week-old pregnancy would lead to a birth.
So far all cloned animals have suffered from some different serious disorders, many of them dying soon after their births.
Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one.
“There are no benefits of cloned human beings, just harm,” said Dr .Michael Wilks of the UK.
1. What is the doctors’ general attitude to cloning of humans according to the passage?| A．They are against it. | B．They support it. |
| C．They welcome it. | D．They pay no attention to it. |
| A．order that forbids cloning | B．suggestion to carrying on cloning |
| C．anger at cloning | D．cheer for cloning |
| A．Dcotor Severino Antinori is strongly opposed to cloning human beings. |
| B．Up to now, seven kinds of animals have been cloned, including sheep, cats humans and rabbits. |
| C．Professor Rudolf Jaenisch is carrying on an experiment on cloning an eight-week-old embryo. |
| D．Ronald Green doubts about the future successful birth of the so-called cloned embryo. |

| C．Failure of Cloning Humans | D．First Cloned Human |
5 . Today, the world celebrates the United Nations International Day of Older Persons (UNIDOP) under the theme “Resilience (复原力) of Older Persons in a Changing World”.
The number of older persons worldwide is projected to reach more than 1.5 billion in 2050. All regions will see an increase in the size of the older population between 2022 and 2050. Less developed countries excluding the least developed countries will be home to more than two-thirds of the world’s older population (1.1 billion) in 2050. Yet the fastest increase is projected to take place in the least developed countries, where the number of people aged 65 or over could rise from 37 million in 2019 to 120 million in 2050 (about 225%).
As to the “Silver Generation”, all countries have to bear increased pension (养老金) and healthcare costs as people live longer. But including the elderly in a productive way in the national economy has become a major problem for many countries. Many young families also struggle to care for their elderly parents or give it up altogether. Meanwhile, though older persons continue to meaningfully contribute to their political, economic, social and cultural lives, their contributions and experience are largely ignored.
The 2022 theme of UNIDOP serves as a fillip, something that jogs your memory and makes you think about the significant role older people play in taking up global challenges and contributing to their solutions. UNIDOP 2022 is also a call for action and opportunity to hear older persons’ voices and show their resilience and contributions in society.
Age is just a number and only a state of mind. Indeed, what matters is ageing elegantly, accompanied by good health. It is meaningless to live to 85 or 90 if one is limited to bed, unable to move around. But this could be a thing of the past in the light of rapid medical advances, which will give mobility and a new life to the elderly. I believe there will come a time when one’s actual age doesn’t really matter anymore in both a physical and mental sense.
1. Why are the figures used in paragraph 2?| A．To clarify the gap between rich and poor. |
| B．To show the growth in the older population. |
| C．To explain the correctness of the UN statistics. |
| D．To analyze the reasons for population ageing. |
| A．It is a double-edged sword. |
| B．It is a force to be treated seriously. |
| C．It is a huge burden to young families. |
| D．It is a by-product of the economic development. |
| A．Reference. | B．Guideline. | C．Reminder. | D．Platform. |
| A．Age affects both physical and mental health. |
| B．Age is not a number but a mental state. |
| C．Age does not matter in the medical field. |
| D．Age pales by comparison with health. |

7 . Being healthy is important. Often, we’re crazy about articles in health magazines talking about the latest popular diets, or advertisements that offer cures (疗法) for fatness that are often too good to be true. One of the latest crazy phenomena (现象) is intermittent fasting (间歇性禁食).
There are different ways of intermittent fasting.
Some people try intermittent fasting for weight management, and others use the method to deal with some conditions such as high cholesterol or arthritis.
As with many diets, it’s always wise to speak to your doctor or weight-loss professional before changing your eating habits. And, at the end of the day, it could just come down to what lifestyle choice suits you.
| A．But what is intermittent fasting? |
| B．However, this diet isn’t for everyone. |
| C．Intermittent fasting has two main origins. |
| D．Let’s look at some of the possible benefits. |
| E．The idea of this is to reduce calories over a period. |
| F．In a word, you should avoid turning to intermittent fasting blindly. |
| G．You can eat normally on five days of a week and reduce calorie intake on the other two. |
8 . Taking exercise in a crowded, noisy gym will improve your muscle but may not make much difference in your stress level. By contrast, hiking improves not only your physical fitness level, but your mental health as well. “I hike with friends every week. Whether I am wandering down a flat path along a river or climbing a rock y mountain in the wilderness, hiking can be beneficial to me because it exposes (使接触) me to outdoor scenes such as mountain s and rivers, which can always offer me good ideas about paintings and music,” Marry Copper, a hiker said.
Experts agree that hiking reduces stress. According to the Anxiety Disorders Association of America (ADAA), hiking increases the body’s production of endorphins, a type of chemical that improves mood (情绪). Endorphins also help you sleep more soundly, which will lower your stress level. However, not all scientists agree that hiking raises your endorphin level. Instead, some researchers believe that hiking causes the release of the chemical norepinephrine, which helps make you less excited or upset.
The controversy (争议) is ongoing, but it is clear that however it happens, hiking is useful when you are feeling anxious. Hiking can also help improve your confidence. Walking down a path is a repetitive motion, which can lead your brain into relaxing; you may “zone out” to the point where you won’t be thinking about anything in particular. Being outside in the open air may also help you exercise better because most people do indoors; getting out from under a roof can lift your spirits.
Hiking may improve your mood more than a gym workout will, but your risks are also greater. People sometimes try to make their own way rather than stick to established paths. They are proud to say they like to have an adventure. However, people who try to do something new could be attacked by wildlife and get hurt and lost. So stick to the known roads and bring a cellphone with you, and always tell someone where and when you are going hiking, even if you have a partner going with you.

9 . This is the last Christmas that Faye and Matthew have spent in their house, which has already been sold. Faye and Matthew Gooding and their five young sons appear to have perfect lives. For the couple themselves, however, this “materially perfect world” was lacking in something—so now they are giving up all their possessions to travel around the world with their children. Most of their belongings have been given to their neighbors. Faye said, “It is a relief to get rid of so many possessions. Thankfully, our parents understand and support us.”
“I hesitated for a while because some friends think Faye and I are mad to give up so much. When we told the older boys, they were so excited that they were going to have so much time as a family. It made me realize the amount of toys or material possessions can’t replace time spent with our children. They’ve had to give away so many toys, bikes and books. My wife Faye was so determined to keep to our plan,” said Matthew.
They will leave this month and plan to start their travels in Sweden where they have friends. Faye said, “My older boys plot where we go next but we hope to see Europe and over two years travel as far as Japan, America, Bali and Thailand. We don’t plan to hire any tour guides. We just depend on a compass and local people to move in the right direction.”
Faye, who posts on Instagram as a mother of five boys, added, “It is a risk because we are giving up so much. I, however, even plan to quit my job after the travel. We can’t wait to spend more time with our sons without the stresses of everyday routines. We don’t know what will happen, but we do know if we didn’t do this we would always regret it.”
