Last month, a Uber driver stopped her work so she could help a helpless new mother with a sick child.

John Henry, Linda’s son, was born with a serious disease. Linda and her husband, who live in Kansas City and are both excellent athletes in the US, tried to find a doctor from Minnesota and Missouri to treat John Henry for the condition—but failed. Luckily, Linda managed     1     (contact) the best doctor in the world in St. Petersburg, Florida. The doctor asked for many of the     2     (detail) of the baby’s disease. It was said that the doctor was quite     3     (responsibility) and able to treat the disease so Linda said to her husband, “Next week I     4     (travel) to the Sunshine State to give our newborn son a fighting chance.”

After John Henry was put into the ICU, Linda decided to go and buy him some new clothes. Upon ordering a Uber ride to the nearby clothing store, she was picked up by a woman     5     age was about forty. Her name was Nancy.

Shortly after she got into Nancy’s car, Linda couldn’t help having a talk about her heartbreaking situation. “She told me her story and I really felt sorry for her,” Nancy said. Rather than simply drop Linda off at the store,     6     (amazing), Nancy parked the car and took her passenger to the store so she could treat John Henry to new clothes.

Linda said, “For this stranger to go completely out of her way, who stopped what she was doing and stopped making money to come to be with me for     7     couple of hours, it was just moving and unbelievable.” Moved by Nancy’s good deed, Linda applied     8     a job in a charity (慈善组织) last week and signed     9     for some voluntary work to give a hand to others in trouble. Now Linda has changed her former personal     10     (prefer) and spends more time caring for her child and doing some volunteer work.

Emerging evidence in humans suggests a     1     (typical) Western high-fat, high-sugar junk food diet can quickly weaken your brain's appetite control.

After offering volunteers a week-long binge (大吃大喝) of waffles, milkshakes and similarly rich foods, researchers in Australia found young and healthy ones scored worse on memory tests and experienced a     2     (great) desire to eat junk food, even when they were already full.

The findings suggest something is special in the hippocampus (海马体)-a region of the brain     3     supports memory and helps to regulate appetite. When we are full, the hippocampus is thought to quieten down our memories of delicious food, thereby     4     (reduce) our appetite. When it’s interrupted,     5     control can be seriously damaged. Over the years, extensive research on     6     (mouse) has found the function of the hippocampus is very sensitive to junk food, but recently this has been observed only in young and healthy humans.

In 2017, after a week of Western-style breakfasts of     7     (toast) sandwiches and milkshakes, researchers found participants performed worse on learning and memory tests which are typically dependent     8     the hippocampus.

Now, in this latest study the scientists of the team     9     (find) that not only do such high-fat, high-sugar diets impair memory in humans, but they appear to directly affect our ability     10     (control) our appetite.

Six weeks before his 97^th birthday, Giuseppe Paternò fulfilled the dream of a lifetime: He     1     (get) a university degree.

Mr. Paternò’s     2     (graduate) has inspired news reports around the world, partly because     3     his age. But he has also drawn attention because his life story speaks of commitment, a theme that has resonated (产生共鸣) as millions of schoolchildren in Italy and elsewhere face extraordinary uncertainty during the coronavirus pandemic.

Born in Palermo in 1923, the first of seven children in a “ very poor family ” , Mr. Paternò began working soon after     4     (finish) elementary school. It was only after he retired, in the mid-1980s, that he returned to his books.

“ His story proves that dreams can come true and that you can remain young — if not in age at least in spirit — if you develop interests. ” said Rosella Cancila, his essay adviser and     5     professor of history at the University of Palermo.

Italy’s university system is based on a three-year degree,     6     (follow) by a two-year master’s course. University officials are hoping that Mr. Paternò     7     (continue) his studies.

He isn’t so sure. “ I have to admit that in this moment, I don’t know     8     I would handle it with the same spirit. ” he said, noting that all the attention had been a bit tiring. Still, Mr. Paternò said, he would     9     (probable) register anyway. “ I want to keep my     10     (choice) open. ”

Chinese astronauts in Tiangong space station opened a science lecture on December 9th, 2021 as they traveled around     1     Earth.

There     2     （be）a lecture and some interesting activities on that exciting day. First, Zhai Zhigang, Wang Yaping and Ye Guangfu, all members of the Shenzhou XIII mission crew, greeted students, teachers and other participants as the lecture began at 3:40 pm. They then showed viewers the place     3     they live and work. The astronauts carried out experiments     4     （show）interesting physical phenomena（现象）in space,     5     （include） "disappearing buoyancy（浮力）" and a "water ball". At last, before the end of the livestreamed activities, they     6     （happy）answered questions from students.     7     （million）of primary and middle school students across China watched the 60-minute televised event, which was the first lecture of the Tiangong Class, China' s first extraterrestrial（地球大气圈外的）lecture series to make students interested     8     space science.

The manned space agency said that more lectures would     9     （hold）based on the country's manned spaceflights and would also be presented by some     10     （profession）Chinese astronauts. Such activities are intended to spread knowledge about manned spaceflights for science among young people.

Finding new passion（热情）

Many     1    （retire）athletes become public servants or help take the reins（掌管）at state-owned- businesses. The data platform of Net-Ease, one of the Internet technology companies,     2    （show）that about 63 percent of 199 Olympic champions from the period 1984 to 2016 hold positions within the government system,     3     about 85 percent work in their own sporting fields.

Those athletes who are     4    （addict）to sports usually push themselves into the fields     5     they started their careers and achieved success.     6    （use）their deep experience, they have trained many other champions. Lang Ping chose to coach the Chinese women's volleyball team. Meanwhile, Liu Guoliang became our head coach of the national table tennis team.     7     of them brought great honor to our country.

Some well-known Olympic champions have done extremely well after starting their own businesses or joining the entertainment industry. Former gymnast Li Ning founded his sportswear empire（帝国）and name brand. Diver Tian Liang has been     8    （attract）to many fans after entering the entertainment industry.

Some athletes choose to pursue（继续）further education. In 2003, Beijing Sport University founded a "champions' class", allowing high-achieving athletes in certain sports     9    （study）for postgraduate degrees without taking any entry exams. Up to now, many other universities have introduced classes that make     10     easier for high-achieving athletes to enter.

You may remember back at the start of December,     1     China carried out their unmanned Chang’e-5 mission and the spacecraft touched down on the moon to collect samples for research. Now it     2    (success) returned to the Earth. This is the most significant event in China’s space field, and also one of the most notable space     3    (activity) globally. Chang’e-5,     4     (launch) by a Long March 5 heavy-lift carrier rocket early on Nov 24, is the nation’s     5    (large) and most complex lunar probe. It returned with 1,731 grams of lunar rock and soil to the Earth,     6    (mark) a historic accomplishment 44 years after the last lunar substances were taken back. The 23-day mission was China’s first space journey to claim extraterrestrial samples, making     7     the third country to accomplish the task, the first being the USA in the 1960’s and the second Soviet Union in the 1970’s.

The spacecraft     8    (enter) the Earth’s atmosphere at an altitude of around 120km. As soon as it was 10km above land, it released its parachute and landed smoothly in China's Inner Mongolia. Now the spacecraft has been air lifted to Beijing where the samples     9    (examine) by scientists very soon.

The mission’s results will contribute     10     mankind’s deeper understanding of the moon’s origins and the evolution of the solar system.
