Bill Bowerman was a track coach. He wanted to help athletes run faster. So he had learnt how to make running shoes. He had also started a shoe company with a friend. It was 1971.Running shoes at the time were heavy. They had spikes（鞋钉）on the sole（鞋底）. The spikes tore up the track and slowed down runners.
To make a lighter shoe，Bill tried the skins of fish. To make a better sole，he wanted to replace the spikes. Bill dug through his wife Barbara’s jewelry box. He hoped to find a piece of jewelry with an interesting pattern. He would then copy the pattern onto the new soles. Nothing worked. Bill was defeated.
Then，one Sunday morning，Barbara made Bill waffles（华夫饼）for breakfast. Bill watched her cook.
He studied the criss-cross pattern on a waffle iron.
Inspiration struck. The pattern on the waffle iron was just what Bill was looking for. The squares were flatter and wider than sharp spikes. The pattern would help the shoes hold any surface without tearing into it.
When Barbara left the house, Bill ran to his lab. He took the liquid chemicals that，when mixed, would harden into the sole of a shoe. He poured the mix ture into the waffle iron—and the Waffle Trainer was born.
Bills company put the Waffle Trainer on market in 1974. It was a huge hit. Maybe you've heard of that company—it’s called Nike. And today it’s worth around $100 billion.
It was the waffle iron that had changed the course of Bill’s life—and helped turn Nike into a well-known name. Today, the waffle iron is kept at Nike headquarters. It serves as a reminder that if we keep trying, we can find a solution to even the most difficult problems. And those solutions can come from unlikely places, even the breakfast table.

A. They were hard to wear.
B. They were too large.
C. They were impractical.
D. They were easy to break.
2.Where did Bill get the inspiration to invent the famous Waffle Trainer？
A. From the skins of the fish.
B. From his wife’s jewelry.
C. From the colour of the iron.
D. From his wife’s cooking tools.
3.What can we learn from Bill's success？
A. A cheerful wife is the joy of life.
B. Two heads are better than one.
C. Where there’s a will，there’s a way.
D. A bad workman quarrels with his tools.
4.What can be a suitable title for the text？

[山东枣庄三中2020高一月考]Researchers have found that short and intense stair climbing，which can be done almost anywhere，has great benefits for fitness.
The findings make the two most common excuses of couch potatoes untrue: no time and no access to the gym. “Stair climbing is a form of exercise anyone can do in their own home, after work or during the lunch hour,” says Martin, a lead author of the study. “This research takes interval(间歇) training out of the lab and makes it possible for everyone.”
Early studies have shown the benefits of stair climbing over continuous periods of time—up to 70 minutes a week—but researchers wanted to determine if interval training, which includes short and intense exercise separated by short periods of recovery, was a good way to improve heart fitness.
Researchers recruited 31 women and tested the effect of two different experiments, each of which required a 10-minute exercise period, including warm-up, cool-down and recovery periods. The exercise periods were done three times a week over the course of six weeks.
The first experiment included three 20-second periods of continuous climbing in an “all-out” manner. The participants were then compared to those who went through the same experiment using an exercise bike which has already been shown to improve fitness.
For the second experiment, some women climbed up and down one flight of stairs for periods of 60 seconds, an experiment which could be easily done at home.
Both experiments, each including a total time of 30 minutes a week, increased heart fitness, an important healthy marker that is connected with long life.
1. What does Martin say about stair climbing
A. It saves lots of time.
B. It is convenient to do.
C. It requires special training.
D. It is better than going to the gym.
2. Why did researchers do the two experiments
A. To test the results of early studies.
B To encourage people to climb stairs.
C. To prove the benefits of continuous stair climbing.
D. To find out interval training's effect on heart fitness.
3. What can we learn from the two experiments
A. The first one was better for fitness.
B. The second one required less total time.
C. Both of them were good for heart health.
D. People in the second one turned out healthier.
4. What is the best title for the text
A. How Stair Climbing Benefits People
B. Why Stair Climbing Is the Best Exercise
C. Stair Climbing—A Good Way to Increase Fitness
D. Simple Stair Climbing Exercises You Can Do at home

As you’re busy your studies，the weeks during the Spring Festival can be a time when training and healthy eating plans go out of the window. But you can continue running and avoid weight gain during the holiday season. 1
Pick a race
Having a race on your calendar（日历）is a motivation to keep running during the holiday. 2 Check our active com or Running in the City for events near you.
Don’t skip breakfast
If you’re going to a holiday party in the evening，don’t make the mistake of skipping breakfast. You may think you’re saving calories later. 3
Bring your own healthy dishes

4
If you’re heading to an evening event，eat regular meals and snacks every few hours up until party time. You won’t arrive at the party ready to attack appetisers. Make sure you include fibre at each meal because it keeps you full longer.
