The unbearable winter chill can’t stop their steps. With curiosity and excitement villagers at the foot of Mount Qomolangma hurry up to open their parcels at a delivery office. At     1     altitude of 4,119 meters, this is the world’s highest delivery service station.

The delivery office,     2     (locate) in the town of Tashi Dzom in Tibet autonomous region,     3     (set) up in 2016. Before that local people had to spend around four hours collecting parcels from the county center. But the delivery office brings great convenience and therefore encourages more people     4     (order) online. The office handled only 17 parcels in     5     (it) first month. But thanks to the fast-growing logistics (物流) industry, the number has grown     6     (steady) to an average of 200 per month. Not only has the number of parcels increased, but the items being delivered have become richer in     7     (various).

Though people in China’s eastern regions may think it     8     granted, the delivery office indeed makes a difference for the local people.

Tsering Dekvi, a 25-year-old primary school teacher in the town     9     (be) a big fan of online shopping since university. She said, “It is out of my expectations     10     we can have a delivery service here.” Now the service can help people in remote areas explore a different world.

7 . When I was about 5 years old, I experienced my very first random act of kindness. I was sitting at the roadside one evening, crying alone for some reason when suddenly, a boy came up to me and gave me a plastic rose, I remember the moment when I took the rose from his hand; I was smiling from ear to ear, whispering “I want to be like him” to myself as I watched him walking away.

From then on, I made it as my life mission to do random acts of kindness whenever I can. I was very determined to make other people smile. That was the only reason why I joined my school’s Red Crescent Society and became a volunteer. Unfortunately, not everyone thinks in the same way as I did. Whenever I do something nice to others, people around me will start to judge my actions. Often I will just keep quiet and ignore what they say, but every once in a while, they do drive me up the wall.

These people like to complain about how humans nowadays are lacking of humanities and compassion. However, when they actually see somebody doing a good deed in front of them, they start to question and criticize that person’s honesty. Perhaps it is the increasing crime rate and the never-ending rat race that caused them to be so suspicious to nice strangers. In other words, people nowadays have lost sight of the real meaning of kindness and just let it go unnoticed. That is why I think random acts of kindness are really important. These selfless acts are not only capable of bringing joy to the receivers but also to the givers. Because of this, I want to help spread the idea of these random acts to the whole world. I want to show the people how the little things they give could make a big difference in someone else’s life.

8 . College debt is becoming as much of a problem for Americans close to retirement as it is for new graduates. There are now about 8. 7 million Americans aged over 50 who are still paying off college loans. They borrowed the money either to pay for an education for their children or themselves. Their debt is growing fast, increasing by about half since 2017 to a total of $ 370 billion — an average of $ 40, 900 per borrower. In 2019, roughly $4.9 billion was deducted (扣除) right from retirees’ Social Security income.

"Part of the blame falls on the federally backed PLUS program,” said Tara Siegel Bernard in The New York Times. "Parent PLUS loans”, which have few application requirements other than a basic credit check, have broadened access to capital for many parents. But the “loans can be unforgiving”. William and Kate Schweizer “didn’t want their two daughters to begin their adult lives burdened with college debt”. So they borrowed $ 220, 000 for their schooling. Increasingly they had trouble paying. Now their debt has ballooned to $500, 000. The consequences of defaulting (拖欠) are serious: “The government can take their wages and Social Security.”

“Unfortunately, President Biden’s $ 6 trillion budget doesn’t offer much assistance,” said Eric Levitz in NYMag.com. “During his campaign, Biden called for forgiving $ 10, 000 in federal student loan debt for every borrower among other ways to ease the college debt burden. But the chances of passing such measures through Congress are slim.”

“Don’t bankrupt yourself for your kids,” said Beth Akers in USA Today. The safer option to pay for college is “a student loan taken out in your child’s name”. A federal student loan — not a private one — can protect borrowers through income-driven repayment programs. There is also a better chance that a loan forgiveness program could materialize to help out student borrowers. And remember that “if you overextend yourself financially to make a college dream come true for your child, you are taking away your ability to be your child’s financial backstop.”

10 . Physical education(体育), or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students receive physical education? The answer is certainly “Yes.”

Today many people don’t do sports. But as is known to all, doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

The American Heart Association says that 10 million kids and teens suffer from obesity(肥胖症). The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activity each week improved their academic(学业的)performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.
