Last Saturday, my friend and I were walking back home after a nice evening. I     1     (ask) my friend if we could walk through the town instead of taking our usual shortcut. So we did.     2     (sudden), a few     3     (step) ahead, we saw a woman,     4     was sitting on the edge of the sidewalk. She looked bad and when we asked her if she felt all right, we realized she was badly injured     5     covered with blood. While my friend can back to our closest friend’s place to get a thick cover, a young fellow joined     6     (we) and called an ambulance. All along I sat next     7     her, talking and     8     (listen) to keep her awake until the ambulance arrived. She was badly     9     (shock) and started to fall asleep. I knew that it was of great     10     (dangerous) and she might have lost consciousness（意识）. We hope she is safe and sound now.

The tables quickly turned for an 89-year-old pizza delivery driver     1     received a surprise delivery of his own from "regulars". It was     2     $12,000 tip. Derlin Newey was in disbelief. “I don't know what     3     (say), except thank you,” said Newey as he held back     4     (tear) of joy.

Newey delivers pizzas about 30 hours a week. He started the job after realizing he couldn't live just only     5    social security. In addition to being a delivery driver, Newey is also a rising TikTok star thanks to some regular customers inspired by his spirit. The Valdez family said they always asked for him when     6     (order) pizzas and started recording his deliveries. With more than 53,000 followers, they often got comments asking why Newey was delivering pizzas at his age. The family     7     (decide) to do some good.

Newey was     8     (complete) unprepared. He didn't even know what TikTok was     9     was grateful for the unexpected blessing. “I'm glad to help him,” said Valdez. “We just need to treat people with     10     (kind) and respect. He stole our hearts.”

We live in a world of plastic. Shopping bags, drink bottles, your toothbrush and even your clothes are among the everyday items     1     (make) from plastic. But plastic isn’t fantastic, and neither is the current state of our environment.

Humans     2     (produce) plastic on a large scale (大规模地) since the 1950s. We produce hundreds of millions of tons of plastic every year and production is only increasing.     3     (fortunately), most of it is used only once and then thrown away. Only a small part of plastic     4     (recycle). The majority ends up in our oceans.

A Plastic Ocean is a documentary film directed by the Australian journalist Craig Leeson. It investigates the serious harm plastic has done     5     our oceans. What starts off as an adventure to film the blue whale, the     6     (large) animal on the planet, leads to the shocking discovery of a thick layer (层) of plastic     7     (float) in the middle of the Indian Ocean. The film sends the message that our actions and choices can severely influence the planet.

Plastic is so widely used because it is durable (耐用的) and cheap. However, this durability is the same quality that makes it so     8     (harm) to the environment. Most plastics do not break down chemically. Instead, they break into smaller pieces     9     can remain in the environment for     10     long time.

With the     1     (develop) of industry, air pollution is getting more and more serious. In Beijing, many people suffer different kinds of illnesses because     2     air pollution.

Air pollution is caused by the following     3     (factor): about half of the problem is caused by vehicles. There are more and more cars, buses on the roads, and they give off     4     (poison) gases. 25% of air pollution is caused by factories. Another factor is the smokers. Smoking not only does harm to their health     5     to others.     6     these, about 10% of air pollution is caused by other reasons. We should take some measures to fight     7     pollution. New fuel can be used to take     8     place of gas. We can plant more trees. If everybody realizes the     9     (important) of environment and does something to stop pollution, the problem will     10     (solve).
