1 . We were in for a whole new way of life when we moved to a horse farm in Winchester,Kentucky. One of the _______ parts of the move was getting to know the people in this small community. Even before we left Florida we had a(n) _______ of the friendliness of the residents and their _______ to help even strangers like us. “Your lower field is flooded,” was the first _______ we received in Florida from the former owner of the farm.

So we knew about the _______ before we moved, but we didn’t figure on how much it would _______ us once we arrived. Every time we went to town we passed those fences, _______face down. The trouble was that we didn’t own a _______ .

One day, our neighbor said, “I _______ to put my cattle in another field for a while. If I use my tractor and __________ your fence, could I use your lower __________ ?”It __________ that we needed him and he needed us. Soon, not only were our fences fixed, but his cattle kept the field __________ and clean. “Isn’t it __________ how we need each other and can each __________ the needs of the other?” I said to my husband.

One night our neighbor asked my husband, “Want to ride with me to __________ my farm?“ So my husband did. When he __________ home, he walked in, smiled and said, “Do you know what? He didn’t need our fields at all. He has 150 acres not even being __________ !” I went to sleep that night thinking about the __________ in our new community and how our new neighbor found a way to help us by __________ he needed us.

2 . Cheating in sport is as old as sport itself. The athletes of ancient Greece used potions to strengthen themselves before a contest, and their modern counterparts have everything from anabolic steroids (类固醇) to growth hormones with which to_________their bodies. These days, however, such stimulants are_________, and those athletes must therefore face the challenges of anti-doping (反兴奋剂) agencies.

The agencies have had remarkable success. Testing for anabolic steroids was introduced in the 1970s, and the incidence of cheating seems to have_________dramatically as a result. The tests, however, are not entirely_________. And a study just published in the Journal of Clinical Endocrinology & Metabolism by Jenny Jakobsson Schulze and her colleagues at the Karolinska Institute in Sweden suggests that an individual’s genetic make-up could_________the tests in two different ways. One genotype, may allow athletes who use anabolic steroids to escape detection altogether. Another may actually be convicting (给……定罪) the innocent.

The test employed for testosterone (睾酮素) abuse usually relies on measuring the_________of two chemicals found in the urine (尿液): TG. and EG.. Any ratio above four of the former to the latter is considered_________and leads to more tests. However, the production of TG is controlled by a gene called UGT2B17. This gene comes in two varieties, one of which has a part missing and therefore does not work properly. A person may thus have none, one or two working copies of UGT2B17, since he inherits one copy from each parent. Dr. Schulze_________that different numbers of working copies would produce different test results. She therefore gave healthy male volunteers whose genes had been examined a single 360mg shot of testosterone — the standard dose for legal medical use — and checked their urine to see whether the shot could be_________.

The result was remarkable. Nearly half of the men who carried no functional copies of UGT2B17 would have gone undetected in the standard doping test.____________, 14% of those with two functional copies of the gene were over the detection threshold (门槛) before they had even received an injection. The researchers estimate this would give a ____________rate of 9% in a random population of young men.

Dr. Schulze also says there is substantial____________variation in UGT2B17 genotypes. Two-thirds of Asians have no functional copies of the gene which means they have a naturally____________ratio of TG to EG, compared with under a tenth of Caucasians (白种人) — something the anti-doping bodies may wish to take into account.

In the meantime, Dr. Schulz’s study does seem to offer innocents a way of____________themselves. Athletes who will travel to Paris for the Olympic games may be wise to travel armed not only with courage and the “spirit of Olympianism”, but also with a copy of their____________, just in case.

3 . It was a normal morning in March. Sondra Artis had just _______ the last student on her route.

As heading towards the school, Sondra noticed a burning smell. She _______ the bus window to see if it was fogging up from condensation（凝结）or if it was _______ . When a student asked her what was _______ , she did her best to hide her growing _______ .

Sondra pulled into a parking lot and turned to face the 20 students on _______ . She reminded them of the evacuation（疏散） _______ they once performed and directed them to leave through the doors.

“I told the kids that, ‘You know, we _______ at the beginning of the year, but this is going to be _______ , so I need you to be calm,’” said Sondra.

The students hurried to the ________ as smoke began to fill the bus. They were ________ , but Sondra remained calm. When they were out, she went back onto the bus to make sure everyone left ________ .

Seconds after they all ________ , the bus caught fire. Another bus came to the ________ to take the children away, and Sondra was left ________ that everything worked out okay.

The bus can be ________ , but human life cannot. The parents were incredibly ________ for her grace under fire. She's being considered as a ________ , and many of her students would like to see her ________ for her heroism.

“Sondra is a very good bus driver，”said a student. “She ________ a reward.”

5 . Nesmith rarely rejoined the others for reunion tours, leading many to believe he disliked the band and the show, something he steadfastly denied. For the Monkees’ 30th anniversary he persuaded the others to reunite to record a new album, “Justus,” for which all four composed the songs and played the instruments. He also rejoined the others for a brief tour and wrote and directed their 1997 TV reunion film, “Hey, Hey, It’s the Monkees.”

6 . A wildfire kills most things in its path, but despite the flames and intense temperatures, rarely is everything reduced to ashes -and that plays a key role in a forest's regeneration. Just one year after the fire, the survivors dominate the forest, and grasses replace the burnt ground. Wildflowers are abundant bushes and small trees have started to grow, and Jack Pine returned. So, it's an amazing ecological system of creating new forest life when it appears that all is lost, one that has evolved throughout the ages, where fire has always played a vital role.

7 . Over the next few weeks, Mika would stop by occasionally. Sometimes, she only stayed for a few minutes; other times, she would wander around my apartment much longer. Each visit brightened me. Mika even helped me connect with some new neighbors, who asked if Mika was my cat. Apparently, Mika visited them as well.

While the lockdown has been awful, I suspect I might not have ever met Mika if it had not happened. But perhaps she came by at this time because she sensed a need for connection on my part.

While dogs are said to be man’s best friend, a good cat can be everyone’s best friend.

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.
