Winners Are Made, Not Born

No one is born a winner. People make themselves into winners by their own ______. I learned this lesson from an experience many years ago. I took the head coaching job at a school in Baxley, Georgia. It was a small school with a weak football program.

It was a tradition for the school's old team to play against the ______ team at the end of spring practice. The old team had no coach, and they didn't even practice to ______ the game. Being the coach of the new team, I was excited because I knew we were going to win, but to my disappointment, we were defeated（擊敗）.

Thinking hard about it, I came to realize that my team might not be the number one team in Georgia, but they were depending on me. I had to change my ______ about their ability and potential（潛力）.

I started doing anything I could to help them build a little pride. Most important, I began to ______ them like winners. That summer, when the other teams enjoyed their vacations, we met every day and practiced passing and kicking the football.

Six months after suffering our defeat on the spring practice field, we won our first game and our second, and continued to ______. Finally, we faced the number one team in the state. I felt that it would be a victory for us even if we lost the game. But that wasn’t what happened. My boys beat the best team in Georgia, giving me one of the greatest ______ of my life！

From the experience I learnt a lot about how the attitude of the leader can affect the members of a team. Instead of seeing my boys as losers, I pushed and encouraged them. I helped them to see themselves ______, and they built themselves into winners.

Creative and New Ideas from Teenagers

Teenagers are known for being creative and full of new ideas. Let's have a look at these teenage inventions that might change the world.

Banana leaves usually go bad in two or three days. Richard, a teenager from India, used UV to make the leaves stay fresh for a year. Richard thinks that one day the leaves will be used for making plates, cups and other things.

David, an American teenager, built an earthworm (蚯蚓) robot. It is able to go into the smallest places, where humans or dogs can't go. It will be finding people in a fire or an earthquake.

Sara, a 14-year-old girl, from South Africa, found it tiring and boring to hand wash clothes in the nearby river. She reused some bicycle parts and created a washing machine that saves time, energy and keeps people fit at the same time.

Alex, a 15-year-old boy, from England, noticed that his grandfather who got Alzheimer's disease（老年癡呆）would often leave home and get lost. So he invented the wearable sensors（感應(yīng)器）to help people find their family members like his grandfather.

1.Who built an earthworm robot?

A.Richard. B.David. C.Sara. D.Alex.

2.The wearable sensors invented by Alex can ___________.

A.make things stay fresh B.help people wash clothes

Best Trip I've Ever Had

Clara Daly was seated on an Alaska Airlines flight from Boston to Los Angeles when she heard a worried voice over the loudspeaker：“Does anyone on board know American Sign Language? We need your help.”

Clara, a fifteen-year-old girl at the time, pressed the call button. An air hostess came by and explained the situation. “We have a passenger on the plane who's blind and deaf,” she said. The passenger seemed to want something, but he was traveling alone and the air hostesses couldn't understand what he needed.

Clara had been studying ASL for the past year to help blind and deaf people and she knew she'd be able to finger spell into the man's palm. So she rose from her seat, walked toward the front of the plane, and knelt（跪）by the seat of Tim Cook, a sixty-four man. Gently taking his hand, she signed, “How are you? Are you OK?" Cook asked for some water. When it arrived, Clara returned to her seat.

She came by again a bit later because he wanted to know the time. On her third visit, she stopped and stayed for a while. “He didn't need anything. He was lonely and wanted to talk, ”Clara said.

So, for the next hour, that's what they did. She talked about her family and her plans for the future. Cook told Clara how he had become blind over time and shared stories of his days as a traveling salesman.

"Even though he couldn't see her, she looked attentively（聚精會(huì)神地）at his face with such kindness, ”a passenger reported.

“Clara was amazing, ”an air hostess told Alaska Airlines in a blog interview. “You could tell Cook was very excited to have someone he could speak to, and she was such an angel.”

1.What was the air hostesses' problem?

A.They had a very difficult passenger. B.They couldn't understand the passenger.

3.From the passage we can know Clara Daly is ___________.

However exciting space travel sounds, astronauts must still suffer with bad food. Now, food in space has to be dehydrated（使脫水）or pre-cooked and stored. This means astronauts aren't really eating fresh food.

New technology may change this. Scientific American reports that a specially-designed oven will be sent into space this autumn with NASA's NG-12 cargo（貨物）.Far from the common vacuum-packed（真空包裝的）meals, astronauts may get to enjoy freshly baked cookies before the end of 2019.

Why aren't they baking cookies in space already?

For one thing, there's the risk of a fire. Engineers also have to overcome the challenge of microgravity, which prevents heat from circling inside ovens the same way it does on Earth.

Astronauts will still have to wait a while before they can have their cookies, though. After baking, the results will be sent back to Earth for safety testing. If successful, this will be the first oven to bake food in space.

“I believe…that will be game-changing for both science and astronauts, ”food technology researcher Maeena Naman Shafiee told Scientific American.

One of the main driving forces behind this project has been NASA's 2018 research into the effects of " confinement（封閉）and isolation（隔離）”. Unlike on the International Space Station（ISS）, astronauts traveling out of Earth's orbit may not be able to speak to their loved ones on future missions, which could lead to negative feelings.

It's hoped that the chance to bake and sense familiar smells can bring joy to crews（宇航人員）.

“Is the ISS going to smell like fresh-baked cookies? We don't know, ”said NanoRacks' communications manager Abby Dickes. “But that's a feeling we all know and love…that will make someone feel at home.”

Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel. Astronauts have already grown plants aboard the ISS.

With commercial（商業(yè)的）space travel now being planned, who knows what other developments may surprise us in the future

1.What can the new technology help astronauts to do in space?

A.Store more food. B.Enjoy fresh cookies.

C.Quickly prepare food. D.Cook many different kinds of home-made meals.

2.Why is it difficult to bake cookies in space?

A.Because it's difficult and costly to send food into space.

B.Because microgravity stops food from staying in one place.

C.Because baking cookies in space would pollute the spaceships.

D.Because it is hard to heat food properly because of microgravity.

3.What was the main purpose of the cookie project?

A.To improve astronauts' health. B.To make improvements in space travel.

C.To encourage more people to travel to space. D.To make space travel more comfortable for astronauts.
