It was the first day of our youth group ski trip. While I waited for the ski lift, I saw a booth (亭子) _______ ski lessons. I considered taking an hour-long lesson, but then I heard my voice in my head: Nah, you don’t need any help. _______, you’ve skied once before.
As I stood on the edge of the beginner’s slope (斜坡), my _______ shrank, for I hadn’t skied for two years. But _______ enough, I’d be able to figure it out.
So, I pushed off and _______. I was like a _______ moose (驼鹿) on roller skates. My skis crossed each other. I couldn’t stop or _______. I fell about eight times on that beginner’s slope _______ I finally came to a stop by hitting a small tree. The second time down, I only fell four times, so I _______ I was getting better. I rode up for a third try with my friend Jen.
“Todd, you might really hurt yourself,” Jen said gently. “I think you should take a ________.”
I don’t need help! I screamed in my head. With that, I ________ down the hill. Near the bottom, my left ski rocketed out from under me. My upper body threw ________. My entire weight ________ on my face.
As my head pounded and my face started to swell, I finally ________ that I needed help. I swallowed my ________ and marched up to the ski lessons booth.

75 years—that’s how long it took to conduct the Harvard Grant Study that revealed the state of success and happiness depends on two things: love and work ethic (工作准则). 1. And the idea that children doing chores are more likely to succeed is surely new.
Kids who grow up doing chores contribute.
Chores help a person develop a certain attitude which can lead to them taking charge when there’s help needed. 2. Those who’ve learned to take the initiative since childhood are more likely to be leaders.
Kids develop self-efficacy.
When a kid sees that his / her actions lead to a certain outcome, it opens a door to a whole network of other activities like thinking, coping, trying, failing and succeeding. It gives the kid more space to experience life in general. 3.
They become more capable and responsible.
4. And protecting your child from household duties and building a dependent pattern of behavior does more damage in the end. More or less independent living will cause a definite stress for a child who gets used to the fact that a certain part of their life is done without their participation or effort.
They figure out how to get tasks done.
Parents should not put all the effort into kids’ good grades and thick resume, but rather on forming a certain set of habits, skills and a mindset in general. 5. This includes, for example, the ability to schedule a day, prioritize urgent and important tasks.
A.It’s more or less obvious with love.
B.Kids should be rewarded for doing chores.
C.This quality will be useful in group projects.
D.This will help them more in life than good grades ever will.
E.Parents should encourage kids to do chores for the good of health.
F.Chores are a big part of everyday life which is impossible to avoid.
G.Doing chores gives them more control over another area of their life.
Before the end of the year, employees at Ubiquitous Energy, a company in Redwood City, Calif, will gather in a window-lined conference room to stare toward the future. That’s because their new glass windows will offer more than an amazing view of the North California landscape. They will also be able to power the company’s lights, computers and air conditioners.
Several years in the making, Ubiquitous’ energy-producing glass is a remarkable technological achievement. Its power lies in the layers of organic polymers (聚合物) between sheets of glass. As light enters the window,the flow of electrons between the polymer layers creates an electric current, which is then collected by tiny wires in the glass.
“It’s sort of like a transparent computer display run in reverse (反过来),” says Veeral Hardev, director of business development at Ubiquitous Energy. “Instead of electricity being shuttled to different points in a display to light them up, light is producing electricity to be shuttled out of different points in the window.”
Right now the windows produce about a third as much electricity from a given amount of sunlight as the typical solar cells used in roof panels (板).These windows, about half as transparent as ordinary glass, don’t work as well as transparent ones. Hardev says the company is likely to improve the transparency significantly. As for the lower output of electricity, he notes that windows can cover a much greater surface area than a roof, so numerous windows will produce a surprisingly larger amount of electricity than the production from a rooftop full of higher-efficiency solar panels. “You could do both.” says Hardev. “But you’ll get more from the windows. The biggest challenge, he adds, is increasing the windows from less than two square feet currently to about 50 square feet.”

We all know that regular exercise is good for us. In recent years we’ve been told to aim to walk 10,000 steps a day to remain healthy, although other advice to do three 10-minute walks a day is thought to be even more effective. But the latest piece of research might put a spring in your step if you’re someone who walks at a fast pace. That’s because, according to scientists, the speed at which people walk in their 40s is a sign of how much their brains, as well as their bodies, are ageing.
The BBC’s Philippa Roxby writes that tests on 1,000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of “accelerated ageing”. Their lungs, teeth and immune systems were in worse shape than those who walked faster. And to add insult to injury, the study found not only did slower walkers’ bodies age more quickly, their faces looked older and they had smaller brains. Professor Terrie, lead author of the study, told the BBC: “It found that a slow walk is a problem sign decades before old age.”
This might be seen as a wake-up call for people with a slower pace who might feel it’s time to work out and get fitter. But it might be too late; researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will go on to have a healthier life.
So, what’s the point of knowing that a slower walking pace might mean a smaller brain? Well, researchers say measuring walking speed at a younger age, and understanding what this might mean, could be a way of testing treatments to slow human ageing. This might help us make lifestyle changes while we’re still young and healthy. Any steps we can take to prolong a good mental and physical state is a no brainer!
