4 Key Strategies for Running to Lose Weight
As one of the most active exercises out there, running is an extremely efficient way to burn calories and lose weight. A 150-pound person will burn approximately 100 calories per mile when running. 1.
1. Healthy Eating is the First Step
If you want to lose weight by running, keep in mind that you’ll only lose pounds if you burn more calories than you consume. To lose a pound, you have to burn, through exercise or life functions, about 3500 calories. 2. Runners do have special nutrition needs, but the basic principles for healthy eating still apply. Try choosing smaller portions of high-fat and high-calorie foods and eating more whole grains, fruits, and vegetables.
2. Follow a training schedule
Sticking to a training schedule is a simple way to stay motivated to run. 3. So it’s much harder to postpone or skip workouts. Following a schedule can also help you avoid a running injury by not increasing your mileage too quickly.
3. Run regularly
If you don’t want to follow a schedule, you still need to have some consistency with your running because you won’t lose weight by running once a week. It’s best to get some activity every day. 4. If you find that your motivation to run is suffering, follow some necessary tips to get inspired.
4. 5.
Incorporating speed work or interval training (running at a very fast speed for short intervals of time) into your running routine can also help your weight loss efforts. Speed work burns a great amount of calories in a short period of time. You’ll also increase your muscle mass, causing you to burn more calories throughout the day.
A. Keep it challenging
B. Eat for Performance
C. You’ll know exactly what you need to do every day and each run builds on the next.
D. So you’ll need to combine running with a healthy diet.
E. If you’re hoping to use running to lose weight, here’s some advice on how to be successful.
F. Here are ways to improve your running motivation.
G. But if that’s not possible, try to shoot for at least 3-4 times per week.

Most people have had songs stuck in their heads at some point. The scientific name for this is involuntary musical imagery (INMI), which simply means that the people do not choose to keep the songs in their heads. Experts have nicknamed this condition “earworm,” even though it is not an actual worm, and it does not take place in the ear. Rather, it takes place in the memory centers of the brain. It occurs when a catchy tune “sticks” in a person’s mind. What makes a song stick depends on the individual. Some people get stuck on their favorite songs, while others end up fixated (念念不忘的) on songs they find annoying.
Nobody knows exactly why, a particular song gets caught in a person’s brain. It can be brought on after recently hearing a song, or it can be started by a memory. Although earworm can happen to anyone at any time, certain people are more likely than others to suffer from it. Most commonly, musicians experience it, but people who simply listen to music more frequently than others are also more prone to (倾向于) earworm.
No evidence has proven one effective cure, but anything that disturbs the brain can help. The best way to shift the brain is to occupy it with a new activity. For example, actively chewing gum might switch the brain’s focus from the repeating song to the moving jaw. Engaging in a task that requires concentration can remove the annoying earworm as well. However, if the task requires too much effort, it can actually make the earworm last, because the mind tends to wander to escape the difficulty of the job at hand.
While earworm can be very annoying, there is no evidence that suggests it is actually harmful. In fact, some experts are studying earworm to see what they can learn about memory centers. After all, these songs repeat automatically with no effort. What if science could apply this information to learning? What if everyone could learn new things without having to try so hard? If scientists can figure out how to tap into this type of memory, learning might look different in the future.
1.Which description is right about earworm?
A. It is shaped like an insect in the ear.
B. It results from listening to amazing songs.
C. It is a nickname for a disease called INMI.
D. It is a condition happening in one’s brain.
2.Who is more likely to suffer from earworm?
A. A brain scientist. B. A retired physicist.
C. A famous painter. D. A pop music fan.
3.Which of the following activity can stop earworm effectively?
A. Reflecting on the song. B. Going on listening to a song
C. Enjoying a tasty snack. D. Solving a hard math problem.
4.What can be inferred from the last paragraph?
A. Earworm may make learning less painful.
B. Earworm has little to do with memory.
C. Earworm can be cured by the scientists.
D. Earworm does more good than harm.

For most of us, the rain that falls on our roof runs off into the ground or the sewer(下水道) system. But if you want to save a little water and reuse it on your lawns or plants --- or even use it for laundry, dishes, or other needs --- collecting rainwater from your gutter’s downspouts(檐槽的水落管) is a no-brainer.
According to John C. Davis, writing in E / The Environmental Magazine, just about any homeowner can collect rainwater, given that the roof and gutters do most of the work. And since an inch of rain falling on a 2,000-square-foot roof produces some 1,200 gallons of water, you can harvest enough to water your lawn or garden.
Plants and grass actually do better when fed rainwater instead of tap water, which is usually treated with substances that can hold back plant growth. Using rainwater can also extend the life of pipes, since the salts added to tap water may gradually damage the pipes. However, homeowners should set up a water purification system if they do plan to use rainwater for inside needs.
Rainwater harvesting can also be good for the local community, as it reduces the erosion, flooding, and pollution associated with heavy rainfall, and reduces dependence on public water supplies. So some states fund rainwater collection systems in their local communities.
Many varieties of rain barrel(桶) systems, starting at just $100, are available for home use. A typical setup is simply a rain barrel positioned under a gutter’s downspout. Skillful homeowners can make their own water harvesting systems, but buying one is a lot easier. Most garden centres offer a range of choices as well as tips.
1.The underlined word “no-brainer” in Para. 1 probably means something that ______.
A．is hard to deal with B．is very easy
C．is of no real value D．deserves more attention
2.From Paragraphs 3 and 4, we can learn _______.
A．how to set up a water harvesting system B．how a rain barrel system works
C．some advice on saving tap water D．the benefits of using rainwater
3.What is the topic of the passage ?
A．Basic gardening skills. B．Water-saving techniques.
C．Wastewater treatment systems. D．Roof rainwater collection.
