One day, Nick invited his friends to supper. He     1     (prefer) to do such a thing now and then. He was cooking some delicious food in the kitchen. Suddenly, he found that he needed salt. So Nick called to his son, “We are     2     (have) dinner in some time this evening. Go to the village and buy some salt, will you? But pay a fair price for it: neither too much nor too little.”

His son looked a little     3     (amaze). “I can understand the reason why I shouldn’t pay too much, Father, but if I can pay less, why not save a bit of money?”

“That would be a very reasonable thing to do in a big city, but it could destroy a small village like ours. Let’s remember this,    4     we?” Nick said.

Nick’s guests, who had heard their conversation, asked why they should not buy salt more cheaply if they could. Nick replied, “The only reason why a man would sell salt at a lower price would be that he was desperate for (渴望) money. And anyone who took advantage of (利用) that situation would be showing a lack of respect to the sweat and struggle of the man     5     life was poor and who worked very hard     6     (produce) it. We should help those who are suffering     7     poverty or an illness or a disaster. We should help     8     (they) survive from the troubles. Even if we can’t succeed, it is not a     9     (fail) if we have tried our best to help others.”

“But such a small thing couldn’t possibly destroy a village.”

“In the beginning, there was only a very small amount of unfairness in the world, but everyone added a little, always thinking that it was only small and not very important, and look where we have ended up today.”    10     (unique), he expressed his opinion about buying and selling.

Youth volunteers make a difference

Students of a Nanjing senior high school brought joy to     1     elderly and brightened up their day by volunteering at a local nursing home last weekend. The nursing home,     2     (locate) on a housing estate, has more than 150 senior citizens, some of     3     are over 90 years old.

Though it was the first time many of the students     4     (take) part in a volunteer program like this, they were eager to share various interesting topics with the residents, such as how to use mobile phones and go online on the computer, After lunch the residents and the young volunteers amused     5     (them) with art activities which included Chinese painting and calligraphy. They enjoyed each other's company so much     6     Su Ming, 16, said he hoped to return to the nursing home     7     (regular) to spend time with the seniors that he made friends     8     .

Wang Hong, the program organizer, said, “I     9     (concern) that the students and the senior residents wouldn't get along easily, but it turned out to be the exact opposite. I can say that today's activities have made a big difference to the     10     (life) of the residents as well as the students.”

Some misunderstanding is putting shark populations at risk now. Thousands of sharks are dying as    1     result of people’s false beliefs.

Female sharks need males to make babies. Some female sharks have the ability     2    (produce) a baby by themselves and have young sharks without a male shark. That’s something commonly     3    (see) in plants and insects like ants and bees.

Shark fins have medical function.     4    (tradition), it     5     ( believe) that shark fin soup has health benefits and is quite special in China.     6     modern scientists point out that shark tissue(组织) can be extremely high in poison. What’s more, shark fishing kills up to 100 million animals each year, endangering several different species.

If you’re bitten by a shark, you will be a goner. You are more than twice as likely to die from a lightning strike as from a shark bite, according     7     the Florida Museum’s International Shark Attack File (ISAF). “Even if you are bitten, the large     8    (major) of people survive”, says Dr. Chapman. In fact, there were sixty-six unprovoked(无端的) shark bite    9    ( incident) around the world in 2018, only six of    10     were dangerous.

This year, Zhang Guimei sent 150 female students to college from a free all-girls high school she founded in 2008 in southwest China's deep mountains. For the past 13 years, a total of 1,954 female students have graduated    1     this school, the first and only one of its kind in the country.

"To educate a girl is to change the destiny(命运) of three     2     (generation)," Zhang said.     3     64-year-old teacher from southwest China's Yunnan Province was presented with the July 1 Medal by Xi Jinping at a ceremony in Beijing on Tuesday. Because of her efforts to improve female education in China, more girls can change     4     (them) destiny.

When the People's Republic of China     5     (found) in 1949, female illiteracy(文盲) was much higher than that of their male counterparts. In the 1950s, the Chinese government launched campaigns    6     helped some 16 million females become educated.

In recent decades, wiping out illiteracy and     7     (improve) the reading skills of women has been regarded as one of the    8     (high) priorities in China, according to the government's guideline for helping the country's females. The female illiteracy rate for those above age 15 has decreased from     9     (rough) 90% in the early 1950s to 7% in 2019.

In 2021, China scored 0.973 in the Global Gender Gap Report     10     (release) by the World Economic Forum (with a score of 1 being completely equal).
