3 . Two years ago, I was sitting in my car waiting in a long line for a toll booth (收费站). When I ________ reached the booth, the toll operator told me that the person in front had paid for me and I was ________ to go. I was so ________. I didn’t ________ to save the 5 dollars. I would never know who it was. I was ________ by the traffic and the long line, and that gesture was surprising and unbelievable. It really ________ my heart. I ________ to pay the toll for the next car for life.

The first time I tried to pay forward the toll, I kept ________ my rear view mirror to see who I’d be paying for. In the mirror, I saw a tired looking Uber driver. I felt satisfied that my ________ would be going to a good place. But before we got to the ________, the Uber driver had ________ lanes (车道) and now there was someone else behind me. She looked ________ and was gesturing angrily in a ________ with her friend. I wasn’t thrilled to be paying for a woman like that and was ________ judging her by what I was seeing in the mirror. Anyway I paid the toll for both of us and left.

Thirty seconds later I was surprised to ________ a honk (汽笛声). It was the woman and her friend ________ at me from the next lane! She looked bright and ________ . She wasn’t what I thought she was like. This was a valuable ________ that I shouldn’t ________ people so quickly... I don’t know their ________.

4 . As I put down the exercise equipment, my brain tries to focus on what my trainer has said.

“Describe that to me,” asked Rob. He is looking for an answer that required me to connect my brain to my body.

Yes, I know. My brain is connected to my body — the thing that has been carrying my head around for the last 56 years. Since completing my undergraduate degree I have been increasingly immobilized by my working life. Sitting still at a desk, staring at a screen, it’s mostly through my fingers that I connect to my brain.

“I felt great,” I reply. “I could feel it in my back.” Rob is quick to encourage and set up more weight. Then cheerfully he’ll say “okay, next set.”

Every accomplishment in my life has been centered in my head — grades, degrees, promotions, published papers and teaching. But on reflection, I wasn’t paying much attention to my body.

Weightlifting is different. Rob is a trainer and manager at my local gym, my guide in helping me with a single goal — get strong. Despite my age, size and beginner status, Rob has made me feel safe. He is always close by, watching and posing questions. Like “where did you feel that?” or the more general request, “Describe that for me.”

Early on I took these as rote (机械性流程) pleasantries (客套话). Over time I realized he wanted more than just routine answers. Having shown me how to do an exercise, Rob would encourage me to think about the muscle or chain of muscles as they moved. The questions were a test of that connection. Gradually, I started thinking my way back into my body. Not my body as a whole but as individual, connections to newly identified places. Intentionally. Specifically. Magically. It’s surprisingly difficult.

I am five months into a new way of living with this 56-year-old body. It talks to me in a tally different way now. It reminds me of my capabilities, my muscles calling me to move, demanding to be challenged. And I long to continue this dialogue so that I’m ready the next time Rob says: “Describe that to me.”

5 . The engineer’s motto is: “Keep it simple and serious.” But Dr. Arnold, though the fifth woman engineer in history to win the Nobel Prize, is somewhat ________. She always seems to meet something unexpected or have the talent to make things ________.

Here’s a picture of a beaming President Obama, ________ her for winning the National Medal. That should have been a moment of ________. But you can never imagine what happened to her. The minibus that ________ the medal receivers should catch fire at the White House door. The bus filled with smoke, passengers within were gasping and crying and staggering toward the ________, the younger ones carrying the older ones — and all were greeted by a team of Secret Service agents, ________ aimed at the medalists’ heads. They were amusingly ________ as terrorists. What a joke!

Another ________ story! When Dr. Arnold and her little son, landed in London, the border agent asked what brought them to the UK. Feeling very proud and hot-stuff, Dr. Arnold ________ she was going to a reception to meet the Queen. She then ________ shot her mouth off about her next award ceremony at the palace in Italy. The agent skeptically ________ her slightly disheveled (凌乱的) clothes and demanded the invitation letter. But she said it was in her suitcase. Without more ________, she, along with her son, was grabbed to the detention room (拘留室). They spent the next two and a half hours there ________ their story was verified (证实), and ________ made it to meet the Queen. Once again, the should-be ________ engineer was mistaken. Afterwards, she ________, “We should have been simple, sensed the environment and then respond.” Her son replied, “Mom, next time why don’t you keep your mouth ________.”

See what the engineer has ________ ! Yes, indeed we can never tell one’s experiences from their ________.

6 . High school graduations are one of the most important moments in a teenager’s life. However, heading into the _________ on June 6th, David was stopped at the door by a gatekeeper. So you can imagine how _________ David was. Although his sneakers were not extremely unacceptable, David learned they were in _________ of the school’s dress code and he was _________ entry.

David was about to _________ his chance to walk across the stage with his classmate when he caught sight of a _________ face. Butler, a famous local educator, came to the graduation as a parent. Learning David’s unpleasant situation, he _________ the young man back to the entry to see if he could _________ the gatekeeper’s mind.

“I was hoping that she would let it go, but she _________ not letting this young man in, and I didn’t have time to __________ with her, ” Butler said. “I wasn’t going to let him miss the most __________ moment in his life for anything. ”Without missing a beat, Butler simply changed his __________ with David. Just as the __________ closed, David made it inside the hall. Eventually he __________ David from ruining his graduation day.

Although firstly __________ by the last-minute substitution, Butler’s family were thrilled that his quick thinking turned a very __________ situation into a joyful celebration. “I wasn’t __________ because Mr. Butler is always helpful,” a __________ parent of David’s said.

It’s said that a truly __________ man will give the shirt off his back to someone in need. Now it seems, the saying also __________ to the shoes off his feet.

7 . Of all the problems that people face today, depression proves to be one of the hardest to pinpoint. People often suffer secretly, not wanting to admit their need of professional help. They continue with their normal routines and, many times, unhealthy eating habits. Now, health professionals are actually linking diet and depression and have found success in using diet to treat the disorder.

Several researchers and Australian institutions at Deakin University in Victoria, Australia, set out to evaluate the direct link between diet and depression. They carried out the study over a 12-week period and observed 67 patients with moderate to severe depression. For their control group, the patients received social support rather than switching their eating habits to a well-balanced diet. The other patients then received dietary counseling sessions where they were advised to eat a diet high in fruits, vegetables, and lean meats. After the trial period, over 30 percent of the patients had gone into remission with their depression. Only 8 percent of the control group actually experienced this same improvement. This trial has greatly helped researchers understand and better help patients suffering from depression.

Most Americans today do not associate their diet and depression together. Nearly 60 percent of Americans eat over processed foods. 90 percent of added sugar comes from these processed foods. For people with depression, this diet might give a short energy burst, but it will eventually cause energy to sink, bringing happy moods down with it. Many people also love caffeine, drinking multiple cups each day. Again, they consume extra sugar. However, the caffeine can also disrupt sleep and cause anxiety. In addition, people with depression may have a tendency to turn to alcohol Unfortunately, alcohol depresses the central nervous system, which will directly influence a person’s mood for the worse, especially those dealing with depression.

According to the research, diet and depression do go hand in hand. Those suffering from depression should do away with processed foods as much as possible. With a few simple changes in lifestyle, these patients can improve their mental health and return to normal activities with renewed energy and joy.

8 . Kwane Stewart stepped outside a Modesto, California, convenience store with his morning coffee and spotted a _________ man sitting with his back against the building. A _________ sat in the man's lap. Stewart, a vet at an animal shelter,   _________ its scratched-off fur and chewed-up skin - common _________ of an allergic reaction to fleas (跳蚤). He approached the man and _________ flea medicine for the dog's skin, a gift the man _________ accepted.

“I remember returning a week and a half later, the _________ was coming back and the rash (皮疹) was gone,” Stewart told the Modesto Bee. The man said his dog was _________ sleeping at night again because it was no longer staying up _________ and chewing. “‘And you know,’ he said, ‘I'm __________ at night. I used to be kept awake.’ He started to cry, thanking me repeatedly, and I got __________ up too,” Stewart says.

Stewart was __________. “When you give back, there is something you get in return that feels much __________ I knew I wanted to keep doing it,” he told medium.com. Stewart can often be found __________ dark underpasses alone, anywhere he thinks the homeless might __________, with his medical bag for most of the cases he comes across.

He knows there are some people who question __________ the homeless should even have pets. How can they __________ them on the street? “I think that more than __________, they need a pet and they deserve a pet,” Stewart told the Bee. “They love their pet probably more than the __________ person. Because, you know, the owner is the pet's __________.”

9 . If you look up in the sky, you probably see, at some point, an aircraft. And behind that aircraft are white, fluffy streaks (条纹). And that's what we call a contrail. Contrails are made up of ice crystals that form when aircraft engines emit exhaust (废气) that hits the cold air.

The ice crystals reflect incoming light from the sun back into space, which has a cooling effect on the atmosphere. But the contrails also stop heat coming up from the ground from escaping into space. It is reflected back down toward the ground. And so that's a warming effect. Stettler, an engineer from Imperial College London, says, on balance, contrails warm the atmosphere more than they cool it. And that's mainly because the cooling effect due to reflecting of sunlight can only happen during the day, when the sun's shining, whereas the warming effect due to trapping of outgoing heat happens all of the time.

How long do contrails last? This depends on the atmospheric conditions at the altitude where a plane is flying. Some contrails can form clouds that last for up to 18 hours. During that time, they spread out, trapping even more heat. This process allows contrails to warm the planet about as much as the carbon dioxide emissions from aircraft.

But when Stettler and his team analyzed flight data they obtained of Japan airspace, they found that most contrail warming was caused by just 2 percent of flights. And most of those flights originated in the late afternoon because as the sun goes down, cooling can no longer offset (抵消) the warming. And the warming effect continues to exist throughout the evening into the night. But what if the contrails that contribute the most to warming could be got rid of?

10 . Adnan, a 56-year-old father, wants to make it clear that it's not just mothers who can feel like failures in their home life. “I had the fairytale of what I'd be like as a dad,” he says. “When our first child was born, I had images of all this stuff we'd do together. It didn't include pictures of sleepless nights, or every item of clothing being covered in snot and yoghurt.”

He also says it doesn't get any easier with more children, because each child will have a different personality requiring different methods of parenting. “There's a fine line between child management, focusing on health and safety, and being a present dad, trying to listen to all their voices,” he says.

“No one explains that you're their protector as well as the person meeting their hygiene (卫生) factors, feeding them, listening to playground politics and building their confidence. You're the person who is the narrative in their head about how great they are.”

Adnan says that though he doesn't compare himself with other parents, he still finds it hard to shake the fairytale that is firmly in his head, compared with which he always comes up short. “The continuous refereeing (调解) and the delegate decision-making go beyond anything I've done in the workplace,” he says,

“I keep asking myself' Am I equipped to deal with this?' I'm a father, a counsellor (咨询师) and a coach. There's also something about being a parent in your 50 s: you don't have the physicality of your 30s.”
