For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.

In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.

However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.

“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls,” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, self?harm, low concentration and poor performance at school,” she added.

While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.

Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.

1.According to the passage, we can know ________.

A.it's a good habit to play with smartphones or iPads late into night

B.scientists suggest we should avoid using smartphones or iPads

C.darkness makes a great impact on the amount of melatonin

A.who are young adults or adolescents

Over 500 dogs being delivered to a butcher house were saved by a Chinese animal protection organization. The incident then resulted in a debate among Chinese netizens about the necessity of pouring so much money and efforts into saving dogs.

On Friday, a truck loaded with over 500 dogs was stopped by volunteers from animal protection organization on Beijing section of Jingha expressway.

Beijing Times reported these dogs were being delivered to slaughter houses in the city of Changchun, northeast one in Jilin Province and would be eventually served on dinner tables.

After negotiations (协商) with the truck driver and a philanthropic (慈善) founda tion, Shangshan Foundation purchased these dogs with much money. Dogs were then delivered to the headquarter of China Small Animal Protection Association (CSAPA) , being taken care of and waiting for adoption.

After the dog saving mission was reported, Chinese net users debate over whether saving dogs worth so much efforts and money while there are still many poor and needy people in China lacking assistance.

Some net users argue the dog saving mission is placing too much attention to animals while lots of needy people are still left unattended.

A microblogger "Xiaowulaitajie" said on China's twitter-like website, weibo. com, "Dogs are saved, adopted and they attracted media attention. We'd better spend such money and take such efforts in helping the needy people. "

Another microblogger, Liluping, said "We poured such huge sum of money into saving dogs. I would rather the money be spent on disaster relief. "

Some applaud volunteers' actions and show eagerness of offering their helping hands to those saved dogs.

Still many disapprove those "saving dogs" critics. They argue that such act nevertheless embodies social progress.

A microblogger named "broken bridge" said, saving dogs does not go against taking care of people. Such enthusiasm in public affairs will help raise social awareness in helping the needy.

I think people and animals are created equal. Attention should be paid to people as well as animals.

One night in March 1999, a man was driving from California to Oregon, US, to visit some friends. He had stopped his car to have some food when he started to hear strange noises. Turning on the headlights, he saw an 8-foot-tall creature covered in thick, dark hair. The creature stared at him for a minute, turned in the road and walked off slowly into the woods.

In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜马拉雅山地区)and even Hubei Province in China. The creature is known as bigfoot.

Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(类人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.

Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet’s undiscovered secrets. There is a little evidence(证据)to support the believers’ theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.

But so far, no one has found bones or any other definite proof that the giant creature exists.

As a result many people believe the evidence is just part of a big trick.

The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.

They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.

1. So far what we can be sure about is that    .

A. there exist savages(野人)in several places in the world

B. there are some traces of hair, footprints and body prints of the “bigfoot”

C. bigfoot is a direct descendent of ancient gigantopithecus

2.It was in   that man first found the ape-like creature.

A. 1999B. the 1960’s

C. the 1950’sD. the 1940’s

3. The article infers but doesn’t say so that some people    bigfoot’s existence.

A. may fool the world into believing

B. have definite evidences to prove

C. refuse to believe

D. will soon offer proofs of

4.If bigfoot is just a misunderstanding, what they saw might NOT be    .

A. apes

B. bears

C. gigantopithecus

Many people think that the most popular way of communicating with other people is through the mouth. But what they don’t know is that actual communication using the mouth accounts for(占……比例)only around 10%(or even less)of all the means to communicate a message.

Moreover, you can never determine the truthfulness or honesty of people by what they say alone. In fact, words expressed through the mouth often do not reflect what people really think or feel. The more reliable way you can determine their true inner feelings and thoughts is by reading their body language. Everybody communicates using these gestures and if you understand the gestures and their meanings you will be able to read people and know what they are really communicating to you. One researcher even went as far as to say that we speak to hide what’s on our minds. But gestures cannot lie.

Have you ever wondered what it would be like if you can “see through” the emotions of other people? Let’s say you ask a person whether he can do an important task. He says “OK”. But deep inside, you are questioning yourself, “Is he really willing to do this job? ” or “Does he have the confidence in finishing this task? ”You can’t question him directly because that would be like belittling him. And even if you ask him those questions, his replies will not tell you what he really feels or thinks. So the most useful way is to observe his body language. Expressions like smiling, frowning(皱眉), pouting(撅嘴), facial reddening, sweating, toe curling and sideways glances are visible hints that can help you make a right judgment.

1. According to the passage, we know   .

A. words through the mouth are the most common way in communication

B. body language is the quickest way to help people understand each other

C. expressions are the most powerful tool to judge whether a man is confident or not

D. you may know what a person really thinks with the help of reading his body language

2.What does the underlined sentence mean in the second paragraph?

A. We can express ourselves well by body language.

B. We use words to prevent others knowing our true thoughts.

C. Spoken words can fully reflect our true self.

D. We use body language to help express ourselves.

3.The underlined word in the third paragraph can be replaced with   .

A. looking down upon   B. speaking highly of
