1 . The measure of a good night’s sleep is usually based on two things—the amount of time spent sleeping and the quality of that sleep. But now researchers say there is a third thing that matters even more than the other two when it comes to keeping good sleep habits, and that is having a regular bedtime.

A study has found that going to sleep and waking up at the same time every day have an important effect on one’s health. Adults who stick to a regular bedtime tend to weigh less, have lower blood sugar and reduced risk of heart disease.

The researchers studied the sleeping habits of 2,000 adults with an average age of 69. They found that people with greater irregularity (无规律) in their sleep patterns tended to go to sleep later at night, feel sleepy and sleep more during the day, and experienced reduced light exposure. These people were also more likely to be stressed. Among the three kinds of sleep problems, sleep regularity was the most strongly associated with health.

Of course, there are many people for whom this may be impossible, such as night-shift workers or those with late-night duty. But for those who don’t have mandatory (强制的) reasons to stay up late, they should make an effort to go to bed at the same time every night. Skip the late afternoon coffee. Get off the phone. Try this calculator to figure out the best bedtime.

As Matthew Walker, a scientist, wrote, “The shorter your sleep, the shorter your life.” Surely that’s reasonable enough to go to bed on time.

6 . One Concern is an AI company (人工智能公司) in California. It is using machine learning and AI to help firefighters. The company hopes its software (软件) can make exact predictions about earthquake damage. It can tell firefighters how to plan for an earthquake and how to do their jobs better when it happens.

Nicole Hu, a technology officer from One Concern, says the key is to feed the computers a lot of data (数据) about an area. The data may include information about homes and other buildings, the natural environment, and the size of an earthquake. The computers then use the information to make predictions about what would happen if there were an earthquake in the area. It then uses data from past earthquakes to see whether its predictions are any good, and changes its predictive models accordingly.

Gregory Deierlein, earthquake engineer at the Stanford University, says one of the most surprising things about the company’s software is its ability to make use of data from an earthquake as it’s happening, and to change its predictions in real time.

In the past, researchers would collect data after an event and a few years later they’d produce new models, says Deierlein. Now the new models appear in a matter of minutes.

Dan Ghiorso leads the Woodside Fire Protection District (区) near San Francisco, which covers about 32 square miles. He says in the past, when an earthquake hit, he’d have to make educated guesses (based on experience and training) about what parts of this district might be badly damaged and then drive to each place to have a look around. He hopes One Concerns’ software will change that.   “Instead of driving thirty-two square miles, in fifteen minutes on a computer I can get a good idea of the damage,” he says. ‘‘Instead of me taking my educated guess, they’re putting science behind the predictive models.”

1. What do we know about the software’s predictions?

A．They can tell people the size of an earthquake.

B．They are about when an earthquake may happen.

C．They are based on data from many different areas.

D．They can be made before and during an earthquake.

2. What is an advantage of the software according to Deierlein?

A．It can make predictions very fast.	B．It is sold at very low prices.
C．It has many different uses.	D．It can be used by common people.

3. What does the underlined word “that” in the last paragraph refer to?

A．How to save people during earthquakes.

B．How Ghiorso gets to know earthquake damage.

C．How to train firefighters to make guesses.

D．How Ghiorso looks at new predictive models.

4. How does Ghiorso feel about the new technology?

A．Worried.

B．Uncaring.

C．Hopeful.

D．Doubtful.
