1 . It was realized that if an apparatus (装置) could be designed to send out radio waves all the time and record the echoes from any approaching airplanes, it would be a wonderful method of defense in the last war.

Scientists set about solving the problem and radar was invented. An apparatus was made which sent out waves in pulses, and the presence of a distant airplane was shown on the screen (this is what we have in a television set). In this way radar station could detect the approach of enemy aircraft.

After the war radar was put to peaceful uses. It is now installed at airports to guide airplanes down safely in fog. It is fitted to ships so that they are warned of obstructions (障碍物) ahead, such as icebergs. It guides ships into port. It provided airplanes and ships with a magic eye, with which they can see far into the distance, in the dark or in fog.

2 . My brother and I often fight with each other over small things. One day our father said to us, “Tomorrow we will take part in the Ray Home Sports Day. Both of you must go with me. Perhaps you can learn something from those children.” My brother laughed, “Dad, Ray is a home for physically disabled children. What can we learn from them?”

“You will see,” our father said.

Our father works as a volunteer at Ray. The children there have problems with their hands, speech, walking or hearing. Every day, he spends hours helping them to move or exercise their legs or arms.

The following day, he took us to Ray Home. When we got there, we found a nice place to sit down. Finally, the sports began. There was a 50-meter race to see who could run fastest. All the runners were physically disabled. As the race started, all the children moved as fast as they could. Just then, one of the girls fell over and hurt her leg. She began to cry at the top of her voice.

All the children stopped to help the poor girl. Then they all held hands and finished the race together. My brother and I were surprised to see this: the children weren’t interested in winning the race－they were more interested in helping each other to finish the race.

1. Why did the father take the writer and his brother to Ray Home?

A．The father wanted them to do something at Ray.

B．The father asked them to help the children at Ray.

C．The father wanted them to take part in the Sports Day.

D．The father wanted them to learn something from the children.

C．They stopped to laugh at the girl.	D．They didn’t want to finish the race.

3 . How to Talk to Your Parents

You need to talk to your parents about some things.     1    You might be surprised if you give them a try.

    2     Try to talk to your parents a bit every day about little things — the dog, your baseball game, what’s for dinner. This keeps you connected, so moving on to a big topic isn’t so difficult.

Know what you want to accomplish. Do you have some bad news to break to you parents?    3     Or do you just want them to listen to you, without offering any advice? Try writing down for yourself what you want from the conversation. That will help you let your parents know what you need

Pick the right time and place. It’s not a great idea to give your parent bad news when they’re rushing off to work. Talking in the car when you’re doing errands (差事) can be a good time.     4     Go for a run, cry, or hit a punching bag or pillow first.

Find other adults you trust. In some cases, it just may not be possible to talk to your parents. Maybe your mom can’t be there for you because she has her own troubles. Or your dad is not even willing to listen.     5     In that case, find another adult you trust like a favorite aunt, a teacher, or a counselor. The most important thing is to have a reliable adult that you can turn to when you need to talk.

A．But maybe you don’t like to turn to them for personal or social advice.

B．Listen when your parents talk.

C．And if you’re angry, wait until you cool off.

D．Do you need their permission to do something?

E．One of your parents may not even be around.

F．It’s tempting to dismiss your parents’ opinions.

G．Engage in small talk.

I couldn’t help but________— reading his book, getting laughed at by friends, convincing my family that I wanted to “study black holes”... I gathered some________and told him that I joined physics because of his ________ and he was such an inspiration. At first, I wasn’t sure if he understood my thick accent. So I quietly continued my ________. But minutes later________a voice from his computer: “Thank You! I am very glad to see you here.”

It was only then that I________that during the pause he was writing, one letter at a time, while being spoon-fed. It’s how he had been doing unimaginable research almost his entire________. His ability to use his brain in such an incredible way despite a ________body has always inspired me not to be________by difficulties and to concentrate energy on things other than pains of life.

My work keeps me going: it’s my passion, it’s my life and it’s a great pleasure and motivation, which________me to contribute to society. My lifespan (寿命) might be________, but my achievements could be endless. I owe all this to him.

5 . I had an opportunity to teach at a five-star hotel in Nevis, a small island in the Caribbean Sea. After that, my friend Clayton and I flew into Panama City for a surfing outing at a surfing camp in the bay of Chiriqui, whose tourism is booming. To get there, we had to take my tennis bags on and off several buses and boats. After eight hours of travel we finally arrived. The camp was perfect, and the accommodations were not bad. We had an unbelievable week there!

On our return trip, when we got to the bus station, we learned that our bus had been delayed for 2. 5 hours. The sun was beating down on us.

As we walked over to the shaded area, a couple of kids started throwing rocks at me. I opened a can of tennis balls. They stopped and took an interest in the balls. I had a special racket (球拍) with me. I had the strings cut out and replaced them with a net, which is prefect for hotel teaching. I got them to throw the balls into the net. They seemed to enjoy that. Then an older boy got interested, to whom I gave another racket to hit the ball into the net of the catching racket. I showed him how to position and hold the racket. Soon, their bus arrived, and they were on their way.

But families from across the street came over and wanted their 10-minute tennis lesson，too. The other passengers waiting for the bus each got a lesson. Eventually, restaurant workers next door and the bus terminal clerk invited me to give them a lesson, too. They learnt well and were having a great time. And so was I. In what seemed like no time, our bus arrived. Satisfied with what I did, I changed my shirt, and made it back to Panama City.

How Much Is an Olympic Gold Medal Worth?

If the International Olympic Committee still gave solid gold medals to first place finishers, medals would be pretty     1     (value). But after the 1912 Games, they made the switch to silver medals coated in gold.

The gold medals for the Tokyo Olympics,     2     (create) by the Japanese designer Junichi Kawanishi, consist of about 6 grams of gold atop about 550 grams of pure silver.     3     gold and silver rates, like stock prices, fluctuate(波动) pretty     4     (frequent), the value of the medal isn’t exactly static(不变的). But in general, it’s hovering(徘徊) somewhere above $800. A silver medal, which     5     (make) up of 550 grams of pure silver, comes in at $462; and bronze medals, mostly copper and a little zinc, are worth just a few bucks.

But Olympic gold medals have value beyond the sum of their parts, and plenty of     6     (athlete) have hocked(典当) them for much more than $800 or so. Mark Wells,     7     member of the “Miracle on Ice” US hockey team of 1980,     8     (sell) his to a private collector,     9     auctioned (拍卖) it off for nearly $311,000 in 2010. Wells’s teammate, Mark Pavelich, made $262,900 off his own medal four years later.

Others end up in the auction circuit long after the original     10     (own) are gone. In 2013, for example, one of Jesse Owens’s gold medals from the 1936 Berlin Olympics sold for about $1.47 million.

8 . In the deepest dive in a manned submersible(潜水器), US explorer Victor Vescovo spotted and video-recorded a plastic bag and a pile of candy wrappers on the seabed.

His _________ of plastic waste 11.2 kilometers below sea level in the Challenger Deep in the Pacific Ocean, the deepest known point in the Earth’s oceans, means there is _________ on this planet plastic waste cannot reach, _________ it has been found on Mount Qomolangma and in both Arctic and Antarctic waters.

Since the patent(专利) for plastics was _________ in 1907, 8.3 billion tons of plastic products have already been produced, of which 6.3 billion have been poured into oceans _________ processing.

Most of the discarded(丢弃) plastic products _________ in the ocean. In the Pacific Ocean, plastic garbage and other waste have already formed a(n) _________ that’s 1.6 million square kilometers in size. That is the size of Mongolia.

Every year, about 8 million tons of plastic waste flow into the ocean. It is _________ that the total weight of plastic waste will reach 12 _________ tons by 2050, more than the total weight of oceanic fish.

This plastic waste __________ life in the oceans and on the land alike by filling in their stomachs so they cannot eat, or __________ around their bodies so they cannot breathe. It pollutes the __________ and prevents plants’ roots from digging deep into the ground. Plastic micro-particles(微粒) also join the water __________ and enter the bodies of animals, including humans. As humans are at the top of the food __________ , plastic micro-particles accumulate inside our bodies.

We must do something to __________ the situation. Don’t get plastic bags at the supermarket and take your own reusable one __________ . Give up fast delivery lunches and instead cook or go to the restaurant. Get into the __________ of sorting your garbage.

But that’s so much __________ said than done. Environmentalists have been __________ behavioral changes for at least three decades, yet we __________ to use a growing amount of plastic products.

9 . Most important habits to keep your diet healthy.

1. Eat less: the 80% rule

According to the Okinawans, you should eat until you’re 80% full. Okinawans call this rule “Hara Hachi Bu”.     1     it takes about 15 to 20 minutes to inform your brain that you’re full. So when you start to feel like you’re more or less full, you probably are hitting the limit of your appetite.

2. Eat slowly and chew more

    2     So the more you chew, the better you can digest the food when it reaches your stomach. Tip: Don’t hold anything in your hands while you’re chewing. So tonight, I challenge you to put down your cutlery(餐具) and just focus on chewing while you’re eating.

3. Create a consistent eating routine

When your body doesn’t know when it’s getting food again, your body will go full “survival mode”. Your body will start storing every meal as fat in fear of running out of energy reserve. None of us want that.     3     Some people say eating every 2 to 3 hours is the way to go. Others say intermittent fasting(禁食)works for them. Others eat like the kids — consistent eating routine:     4    

4.     5    

The healthiest people (who also tend to be thin) follow a vegan diet, which means they eat plants. Most of the chronic diseases like diabetes, hypertension, atherosclerosis, gout, can be attenuated(缓解)and even reversed(治愈) by following a plant-based diet and supplementing it with Vitamin B 12 and Omega -3.

A．These are the three most important habits to keep your diet healthy.

B．whatever works for your body.

C．Here’s a simple fact:

D．But how frequent should you eat?

E．Lowering your fat intake is important for a heart-healthy diet.

F．It is not enough to be thin and the operative word is healthy.

G．Digesting your food actually starts in your mouth.
