【題目】 Oscar Valera likes to use 3D printers to build a collection of crafts (模型), but he is now turning his hobby toward the fight against the coronavirus pandemic (新冠大流行).

In just four days, the New Jersey high school teacher has printed and distributed 200 face masks to medical professionals across the country, including Florida and Texas. He is far from done. “One woman told me what you’re doing right now is giving people peace of mind. You’re probably saving lives,” said Valera, who found a mask design posted online.

Demand for face masks, along with N95-masks and other personal protective equipment (PPE) has increased with the surge (大量涌現(xiàn)) of patients infected with the highly infectious virus. That has prompted volunteer 3D printers like Valera to step in to support doctors, nurses and first responders, who are all in danger of contracting the sometimes deadly illness.

In Sunnyvale, California, community workspace nonprofit Maker Nexus has been running its 13 3D printers and three laser cutters (激光切割機) nonstop. The company produced 1,800 masks for local hospitals and now has requests for another 13,000.

Elsewhere in Silicon Valley, more companies are joining in. Fremont-based PrinterPrezz, a 3D-printing medical device contract manufacturer that specializes in metal spinal implants, switched production to printing PPE after getting a request from nearby Washington Hospital Healthcare System.

Snap Lab, a unit of Snap Inc, is also producing face masks to donate to hospitals. In New Jersey, Valera said he will continue to do his part. “I don’t mind doing this,” Valera said. “I just hate the fact that I have.”

【題目】閱讀下面短文，根據(jù)所給情節(jié)進行續(xù)寫，使之構(gòu)成一個完整的故事。

Twenty years ago, I drove a taxi for a living.One night I took a fare at 2:30 AM. When I arrived to collect, the building was dark except for a single light in a ground floor window. I walked to the door and knocked. “Just a minute.” answered a weak, elderly voice. I could hear something being dragged across the floor.

After a long pause, the door opened. A small woman in her 80’s stood before me. She was wearing a print dress and a pillbox hat, like somebody out of a 1940s movie. “Would you carry my bag out to the car?” she said. I took the suitcase to the cab, then returned to assist the woman.She held my arm and we walked slowly toward my car.

She kept thanking me for my kindness. “It’s nothing”, I told her. “I just try to treat my passengers the way I would want my mother treated.”

“Oh, you’re such a good man,” she said. When we got in the car, she gave me an address, and then asked, “Could you drive through downtown?”

I looked in the rear-view mirror(后視鏡). Her eyes were shinning. “I don't have any family left,” she continued. “The doctor says I don’t have very long.” I quietly reached over and shut off the meter. “What route would you like me to take?” I asked.

For the next two hours, we drove through the city. She showed me the building where she had once worked as an operator.We drove through the neighborhood where she and her husband had lived. Sometimes she’d ask me to slow in front of a particular building or corner and would sit staring into the darkness, saying nothing.

As the first ray of the sun appeared, she suddenly said, “I’m tired. Let’s go now.” We drove in silence to the address she had given me. It was a small hospice(臨終關(guān)懷醫(yī)院), with a driveway that passed under an entrance hall. Two nurses came out to the car as soon as we pulled up.

注意：

1. 所續(xù)寫短文的詞數(shù)應(yīng)為150左右；

2. 應(yīng)使用5個以上短文中標有下劃線的關(guān)鍵詞語；

3. 續(xù)寫部分分為兩段，每段開頭語已為你寫好；

【題目】 How to live a happy life? The following suggestions may be of great help to you.

Keep positive. 【1】 Optimists have a 35% less chance of having a heart attack or stroke, are more likely to eat a healthy diet and exercise regularly, have stronger immune systems and even live longer. If you face a challenge or obstacle, you’re more likely to see it as a temporary or even optimistic thing, allowing you to learn and grow.

Start volunteering. 【2】 It can reduce the risk of cognitive (認知的) disorder. It can even help us live longer. Even if you have a little time to offer, just the act of giving has been shown to improve your health, possibly by temporarily reducing your sense of pain.

Be grateful. Counting our blessings protects us against anxiety and depression and boosts optimism. One of the best ways to make thankfulness a part of your life is to keep a journal. 【3】 Keeping gratitude and recording your good deeds may help you live happily.

【4】 People who are more socially connected to family, friends and community are happier. They’re physically healthier, and they live longer than people who are less connected. High-conflict marriages, without much affection, turn out to be very bad for health, perhaps worse than getting divorced. 【5】
