The Science of Risk-Seeking

Sometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth tasking. 1.Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.

The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring.2.As the quality of Risk-taking was passed from on ration to the next, humans ended up with a sense of adventure and a tolerance for risk.

So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 3.

No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 4.To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

5.,for the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

As experts continue to study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

G. New brain research suggests our brains work differently when we face a nervous situation.

A ban on smoking in public places has come into effect in China — home to a third of the world’s smokers. The move is aimed at controlling the number of deaths from smoking-related diseases, running at a million a year. But the rules have been criticized, because they do not include punishments for those who choose to ignore them. Many business owners hate rules that force them to ban smoking because many customers do not like the rules and complain. The rules do not allow smoking in places like restaurants, hotels, railway stations or theaters, but not at the office. Employers have a duty to warn staff off the dangers of smoking but do not have to forbid them from lighting up at their desks.

Shanghai introduced similar rules a year ago, but people do not seem to take much notice of them. Often you find people smoking at the next table while you are eating your meal or having a drink in a bar. The problem is that the rules do not include punishments for businesses or individuals who ignore them.

It appears that many Chinese people are unaware of the dangers of smoking. Research suggests that only one in four knows the harm cigarettes of second-hand smoke can cause. Officials say they have to try to persuade people not to smoke to reduce the numbers dying from smoking-related diseases. But it is hard to deal with the problem and there is still a long way to go.

1.The number of smokers in China makes up about ______ of the world’s smokers.

A. 66% B. 44% C. 33% D. 55%

2.Why have the rules been criticized by some people?

A. Because those people don’t want to be punished.

B. Because they do not include punishments for those who ignore the rules.

C. Because the rules are ignored by all the people who smoke.

D. Because nobody takes notice of the rules.

3.What does the last paragraph mainly talk about?

A. How to punish those who ignore the ban.

B. What the dangers of smoking are.

C. Why it’s hard to ban smoking.

D. How the non-smokers suffer from second-hand smoke.

Got big plans for Friday night? That's OK, we don't either.

Guess we'll all have to make do by watching the celestial(天空的) show that will take place that night.

First, there will be a full moon. That's always fun, but this one will be a little more special. It's known as a “snow moon.” The name comes from the fact that the heaviest snows usually fall during February, according to the Old Farmer's Almanac.

But if that's not special enough, there's also an eclipse(月食) that night. It'll be a penumbral lunar eclipse, meaning it’s a partial eclipse that leaves sections of the moon darkened by the earth's shadow. No, it won't be as spectacular as those "blood moon" eclipses, It'll be subtler. The level of darkness it reached during the eclipse may or may not be apparent; it just depends on where you are when you view it.

In North America, the eclipse begins at 5:34 p.m ET and ends at 9:53 p.m. ET, according to astronomy website EarthSky. The eclipse will be at its height around 7:44 p.m.ET.

If that's still not enough, let's throw in a comet(彗星)to the night's festivities.

Comet 45P (it has a much longer name, but we won't burden you with it here) is visible as it flies by Earth. The comet will get within 7.4 million miles of the planet as it makes its closest approach this weekend, according to Universe Today.

Comet 45P will be the most visible a couple of hours after the eclipse, so look to the skies again around 3 a.m.ET Saturday and find the greenish-blue light with a tail.

And don't forget, a total big-time solar eclipse will streak across the United States on August 21st.

1.According to the text, what can be viewed on Friday night?

A. A blood moon. B. A total solar eclipse.

C. A partial lunar eclipse. D. A comet without a tail.

2.If you want to see Comet 45P, you will need to ________.

A. wait around 7:44 p.m.ET B. stay up until 9:53 p.m.ET

C. wake up before 3:00 a.m.ET D. start watching at 5:34 p.m.ET

3.The author writes the text with the purpose of ________.

A. introducing basic astronomy to the media

B. sharing new discoveries with astronomy researchers

C. promoting astronomical events among science students

D. informing average readers of recent celestial phenomena

4.Which can be a suitable title for the text?

B. Penumbral lunar eclipse will happen on Friday night

C. Suggestions of fun scientific exhibitions for the coming weekend

D. Eclipse, full moon, comet team up to put on a show on Friday night
