5 . Virtually, there is nothing that man cannot do. Only what he has to do is keep doing and doing without being discouraged. Success will come someday or other, though it may apparently be the conception about something that it cannot be done.     1     But the reality is that man’s success depends on whether he can do the toughest tasks successfully. It is because our life is complicated and tough. And to succeed in this tough battle, perseverance and hard work are a must     2    . We can prove this fact when we look at the reality of life and the history of man’s success. Perseverance helps us do what we otherwise would consider impossible to do.

What the world-famous scientist Sir Isaac Newton had done by twelve years’ constant hard work was burnt out by his pet dog. But that could not discourage him a little.     3     It is only for his undefeated perseverance that’ we have been able to have many inventions and discoveries.

    4     He went through thick and thin to reach his destination after months of the strenuous voyage on the sea. He discovered the way from Spain to America and offered the world a new route of communication with America. This outcome of his perseverance will be generated by the world forever.

All the great men in history have written their names in golden letters by means of perseverance.     5     If we all are perseverant in whatever we do, we are sure to stand out as a successful nation in the near future.

South Koreans have enjoyed their first close-up look of new baby giant pandas at a name-revealing ceremony that is also     1     early celebration of the 100 days since the twins’ birth.

What to name the twin sisters was widely discussed among netizens after they were born on July 7 in theme park Everland. The names were     2     (ultimate) decided on through two public voting     3     (procedure). One is named Rui Bao, which means wise treasure, and the other is Hui Bao or shining treasure. Half a million panda lovers helped choose their names with a handful of lucky fans     4     (invite) to the ceremony. “They are even     5     (cute) in real life than they appear on screen,” said a college student in attendance.

The baby pandas,     6     have just begun teething and crawling, are very healthy. Everland has shared videos documenting the pandas’ growth online. The twins’ birth has gained 640,000 views since it     7     (upload). “This feels like a great opportunity to call for better     8     (preserve) of pandas,” said Donghee Chung, head of the park’s zoo. Chung noted that between 40% and 50% of panda births result     9     twins.

Everland said it would monitor the twins’ health     10     (determine) when the twins are ready to be open to the public.

7 . On September 29, 2021, the US Fish and Wildlife Service declared it would be removing 23 species from its Endangered Species Act, including the ivory-billed woodpecker, various Hawaiian birds and freshwater fish, not because they had been pulled back from the edge of extinction, but because the USFWS believed these species would never recover, and were most likely extinct, therefore not requiring protection.

In April, 195 countries are getting together in China for a UN conference to discuss global agreements to protect nature and biodiversity, with the hope of finalizing an agreement to safeguard plants, animals, and ecosystems. However, the new strain (毒株) of Covid-19, Omicron, has potentially thrown the plans into a mess, and negotiators may switch to online talks if travel restrictions to China are put in place again.

“We can't go another four months without any progress” said Georgina Chandler, senior international policy officer at the Royal Society for the Protection of Birds. Conservationists are urging the talks to go ahead —   online if necessary — as the biodiversity crisis shows no sign of slowing up.

“Nature loss has not gone away and threatens both human lives and the global economy,” said Lin Li, director of global policy at the organization. “With one million species currently in danger of extinction, delaying action is not an option.”

Improving conservation and management of natural areas, such as oceans, forests, and wildernesses is crucial to safeguarding the ecosystems on which humans depend. However, forests are still being devastated, often for farming or commercial use. As trees absorb about a third of planet-warming emissions produced worldwide, stopping deforestation is key. At COP26 in Glasgow last November, world leaders plan to invest $19 billion in public and private funds to protect and restore global forests.

It’s easy to feel disheartened by the disappointing news, but the only way to stop more species suffering the same fate is to pay attention and take actions.

8 . Food plays an essential role in our lives and rightfully so: The food we eat is related to our culture.     1    . Don’t believe me? Here’s why food is the best way to understand a culture:

    2    

It doesn’t matter where you’re from-you have to eat. Your social culture most likely developed from the need to eat. Once they surpassed hunting and gathering, many early civilizations organized themselves in ways that promoted food distribution and production. That also meant that the animals, land and resources you were near governed what you’d consume and how you’d prepare and cook it.

Food preservation techniques are unique to climates and lifestyles.

Ever wonder why the process to preserve meat is so different around the world?     3    . In Morocco, if preserved correctly, Khlea, a dish, is still good for two years when stored at room temperature. That makes much sense in Morocco, which has had a strong nomadic(游牧的)population, desert landscape, and extremely warm, dry temperatures.

The main local cuisines illustrate historical eating patterns.

Some societies have cuisines that are entirely based on meat, and others are almost entirely plant-based. India’s cuisine is extremely varied from region to region, with meat and wheat heavy dishes in the far north, to spectacular fish delicacies in the east, to rice-based vegetarian diets in the south.     4    .

Food tourism.

    5    . A food tourist won’t just focus on having a pint at Oktoberfest, but will be interested in learning the German beer making process, and possibly how they can make their own fresh beer. Since their interest in food is more than meal deep, the tourists have the chance to learn local preparation techniques that can lead to other aspects of a particular region’s culture.

9 . Bathing in the forest can effectively reduce stress, lower blood pressure and strengthen immune system. Here are some tips on how to harvest these health benefits.

    1    . The ideal place for forest bathing is in a big forest, of course. But if you live far away from one or don’t have the means to get there, any place that has a lot of trees and quiet spaces will do. For example, you can get beneficial effects even from walking in a city park.

Set aside enough time. To get the rewards of forest bathing, plan to spend two to six hours in the woods.     2    , you can also do shorter walks. But the health benefits won’t be as significant. Therefore, the longer the time in the forest, the better.

Aim to reduce heart rate. Your forest bathing session is a good time to sit or walk or do some gentle tai chi.     3    . The difference between exercise and forest bathing is that you’re going to move very slowly. Forest bathing is about calming down your nervous system and reducing your heart rate and blood pressure.     4    , your tiredness will reduce the effect of forest bathing.

Breathe deeply in the forest. This particular breathing exercise benefits on its own outside of the forest environment.     5    .

10 . New research suggests that a gene that governs the body's biological (circadian) clock acts differently in males versus females and may protect females from heart disease. The study is the first to analyze circadian blood pressure rhythms (节奏) in female mice.

The body's circadian clock-the biological clock that organizes bodily activities over a 24-hour period-contributes to normal variations in blood pressure and heart function over the course of the day. In most healthy humans, blood pressure dips (下降) at night. People who do not experience this temporary drop, called “non-dippers”, are more likely to develop heart disease. The circadian clock is made up of four main proteins (encoded by “clock genes”) that regulate close to half of all genes in the body, including those important for blood pressure regulation.

Previous research has shown that male mice that are missing one of the four clock genes (PER1) become non-dippers and have a higher risk for heart and kidney disease. A research team studied the circadian response and blood pressure of female mice that lack PER1 and compared them with a healthy female control group. On both low-and high-salt diets, both groups “retained an apparent circadian rhythm” of blood pressure, the researchers explained. Unlike the male mice in previous research, the females without PER1 showed normal dips in blood pressure overnight.

These results suggest that the lack of PER1 acts differently in males and females. The findings are consistent with research showing that women are less likely to be non-dippers than men of the same age. "This study represents an important step in understanding sex differences in the regulation of cardiovascular (心血管) function by the circadian clock," the researchers wrote.
