1     (我写信感谢你的及时救援), without which my life couldn’t return to normal.

A few days ago,     2     (一场极其可怕的地震袭击了我的家乡), leaving many houses in ruins.     3     (shock) to find everything buried under the fallen houses, I burst into tears.     4     (世界似乎到了尽头). Thankfully, although you were strangers, you     5     (不遗余力) provide enough food and water for us to survive on. With strong support from the government and your generous aid, a new town was built upon the earthquake     6     (ruin).

I can’t express my gratitude too much.

Yours sincerely,

Nicholas, intrigued by adventure stories,     1     (出发去滑雪) with his father. They had a wonderful day. When they were to leave, Nicholas decided to go down unusual trails himself. Unfortunately, a fierce snowstorm swept the area and Nicholas was lost. He remembered the story he ever read, in which a man was abandoned in a wild area and had to help himself out. “I would not shrink from danger. It’s time to     2     (我学到的技巧付诸实践了),” he whispered. He determined to     3     (逃命). Although in a subdued mood, he would not retreat.     4     (再三考虑之后), he     5     (全身心地建一个雪洞) to keep himself warm. The next day, he was found by his father, safe and sound.

Suddenly, the aftershock struck, which made the rescue work more difficult. “A nurse in the ward was covered with rubble,” a doctor screamed with horror then. We volunteers rushed to     1     (帮助医生抢救被掩埋在废墟里的护士). Although we were faced with falling rubble from time to time, we focused our efforts on removing the bricks and the rubble that trapped her.     2     (通过我们的共同努力), the nurse was rescued. It was a miracle that she survived the earthquake.     3     (我们的努力和付出是值得的).

One day, while Tom was behind the wheel, some yellow vests     1     (分散了他的注意力). It is some volunteers dedicated to environmental protection work who are cleaning up the garbage on the roadside.     2     (相比) those who spit in public and litter about, these volunteers       3     (激励他做一些促进环境保护的事情). On reflection he decided to join the volunteers since the beautiful environment       4     (依靠每个人的贡献).

About 75 percent of the city’s factories and buildings, 90 percent of its homes, and all of its hospitals were gone.     1     covered the ground like red autumn     2    .

With the    1    (发展) of economy, people are    2    (遭受) more and more     3    (自然的) disasters. Due to the strongest typhoon called “Dussuri”, there was a heavy rain in many areas and it caused great losses,    4    (尤其) in the north China. The roads were    5    (覆盖) with water and thousands of houses were     6     (破坏). In case of disasters, we are supposed to keep    7    (镇静的) and try to escape in time.

The bad weather may have something to do with the worsening of environment. People may think that big things must be done to protect the environment. Many forget protecting it begins with small things. For example, it’s a good idea to use reusable bags instead of     8    (塑料的) bags. You can also save electricity by turning off lights before leaving a room. Never use    9    (木制的) chopsticks when you buy takeaway food. All these small things can add up and make a big     10    (差异).
