1 . A Race against Death

It was a cold January in 1925 in North Alaska. The town was cut off from the rest of the world because of the heavy snow.

On the 20th of that month, Dr. Welch _________ a sick boy, Billy, and knew he had diphtheria, a deadly infectious (传染的) disease mainly affecting children. The children of Nome would be _________ if it struck the town. Dr. Welch needed medicine as soon as possible to stop other kids from getting sick. _________ , the closest supply was over 1,000 miles away, in Anchorage.

How could the medicine get to Nome? The town’s _________ was already full of ice, so it couldn’t come by ship. Cars and horses couldn’t travel on the _________ roads. Jet airplanes and big trucks didn’t exist yet.

_______ January 26, Billy and three other children had died. Twenty more were _________. Nome’s town officials came up with a(n) _________. They would have the medicine sent by _________ from Anchorage to Nenana. From there, dogsled (狗拉雪橇) drivers — known as “mushers”—would __________ it to Nome in a relay.

The race began on January 27. The first musher, Shannon, picked up the medicine from the train at Nenana and rode all night. __________ he handed the medicine to the next musher, Shannon’s face was black from the extreme cold.

On January 31, a musher named Seppala had to __________ a frozen body of water called Norton Sound. It was the most __________ part of the journey. Norton Sound was covered with ice, which could sometimes break up without warning. If that happened, Seppala might fall into the icy water below. He would __________, and so would the sick children of Nome. But Seppala made it across.

A huge snowstorm hit on February 1. A musher named Kaasen had to brave this storm. At one point, huge piles of snow blocked his __________. He had to leave the trail (雪橇痕迹) to get around them. Conditions were so bad that it was impossible for him to   __________ the trail again. The only hope was Balto, Kaasen’s lead dog. Balto put his nose to the ground, __________to find the smell of other dogs that had traveled on the trail. If Balto failed, it would mean disaster for Nome. The minutes passed by. Suddenly, Balto began to __________. He had found the trail.

At 5:30 am on February 2, Kaasen and his dog __________ in Nome. Within minutes, Dr. Welch had the medicine. He quickly gave it to the sick children. All of them recovered.

Nome had been __________.

3 . Walking or running outdoors, people usually see rubbish all over the ground. Well, some people are doing something about it.     1     “Plogging” began in Sweden. The name connects the Swedish word “plocka” which means to pick up, and the word “jogging” which means to run slowly.

A Swedish man named Erik Ahlström, started the movement in 2016. He moved to Stockholm from a small community(社区) in northern Sweden. Each day he would ride his bike to work. He became worried about the amount of rubbish and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the rubbish.     2    

Today, plogging is an official activity, which is becoming more and more popular. People of all ages are welcome to plog. Exercise while helping your community.     3     It can also build closer social connections in a community. When the street looks bad and it’s dirty, you’re going to feel bad about the community. You may even feel less safe because of that. So if we’re all doing our part and picking it up, it’s very easy to help beautify it, and help build those social connection.     4     You get to feel some social duty when you do this.

Along with cleaning up the environment, there may be another reason to choose plogging instead of just jogging. You may get a better workout. One fitness app, Lifesum, records one hour of plogging as burning 288 calories.     5    

As can be seen, cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. People would think twice before dropping a garbage on the ground.

Tomb-Sweeping Day is one of the eight most important traditional     1     (festival) in China. The actual day usually occurs around April 5 of the Gregorian calendar but the festival lasts longer. Traditionally,10 days before and after Tomb-Sweeping Day can be counted as the festival. The festival is said to originate from the funerals of emperors, generals and ministers     2     ancient times. The rituals (仪式)     3     (perform) at these funerals later became popular among ordinary people. Over time the tradition of offering sacrifices to the ancestors and sweeping tombs has been passed down from generation to generation and evolved into     4     custom widely observed by the Chinese nation. Despite the festival having no official status, the overseas Chinese communities take this festival     5     (serious) and observe its traditions faithfully .

Tomb-Sweeping Day is also known as the Qingming Festival-when spring is in the air, the earth looks clearer and     6     (bright) with increasing rainfall, and everything in the natural world waves goodbye to the unpleasant memory of winter. This     7     (consider) as a shift from yin to yang. During this beautiful season, flowers blossom in the     8     (warm) and everything is full of vitality. The tradition of spring outings     9     (date) back to the Tang Dynasty. Apart from enjoying glorious natural scenery, outings involve other activities     10     serve to bring out the best of the festival.

5 . The age range between about 13 and 19 is an important time in an individual’s life.    1    While you are a teenager, many exciting opportunities for success are given to you. Taking on the right amount of responsibility and independence can push you towards becoming a successful teenager.

First, participate in extra-curricular activities. Schools give students opportunities for staying active. Pick an activity that appeals to you such as athletics, academic clubs, or special-interest clubs. Extra-curricular activities build character through team work, time-management, and competition. Don't be too worried if you aren't very good at what you like, for the important thing is passion.    2    

Besides, volunteer.     3    Meanwhile, volunteering can teach you job-related skills such as responsibility or time-management. Some schools also reward the learning aspect of volunteer work with credit hours. If you are interested in college, volunteering makes you much more appealing during the application process.

Third, use your summer for academic programs. Getting a head start at college could mean sacrificing your summer vacation. Various universities offer programs for future college students based on interests such as journalism, photography, art, sports, etc.    4    Research different programs and then figure out which one is the best choice for you. Check the requirements and deadlines. Avoid getting into trouble because of a simple mistake, and you will have a great time.

Finally, know when to ask for help and advice. Being responsible and independent does not mean being alone.     5    So, seek advice from parents, older siblings, advisors at work, teachers, or someone whom you trust. Opening up channels of communication at a young age is a great habit for success.
