More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night’s sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends.

Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen.

Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, “Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed.”

They wrote in the journal Applied Ergonomics(應(yīng)用人類工程學(xué)) that iPad makers should adjust the spectral power distribution(光譜功率分布) of the devices so that they affect the sleep patterns of users less.

It is not just a good night’s sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.

1.Blue light prevents iPad users from sleeping well because ____.

A. it is the same as daylight which keeps people awake

B. it makes the brain more active

C. it is brighter than light that is more orange or red

D. it can help decrease the production of melatonin

2.The underlined phrase “dim the display” means ____.

A. keep away from the display

B. make the display less bright

C. clean the display carefully

D. turn off the display

3. In the last paragraph, the author intends to ____.

A. warn of the seriousness of long-term poor sleep

B. call on researchers to study sleep patterns

C. show the danger of obesity and cancers

D. show how sleep is harmed by using iPads too much

4.What’s the main idea of the passage?

A. Scientists are warning that blue light is bad for our health.

B. People should limit the use of electronic devices

C. Using iPads before bed can cause a poor night’s sleep.

D. Looking at screens of iPads increase chances of sleeplessness.

A student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃驚的) ways of cheating every day; some claim that certain accounts of cheating can be justified, but overall it can always be prevented.

Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The Internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.

There are countless opinions on whether or not cheating can be justified. The truth is this behavior will always be a matter of opinion with each scenario of cheating. Students often rationalize their cheating by claiming they forgot to look over the material or did not understand what the teacher or professor was saying. Some may counter these arguments by saying that the students could have set reminders or asked the teacher to explain the material before the day of the test. Some other reasons why students believe cheating is justified are their heavy workloads and trying to find time for school, sports, friends, and family. This may be true in certain instances, however, all students have these problems, and it is unfair to the students who refrain(忍耐，節(jié)制) from cheating when the student who is dishonest receives a better grade. The majority of students who think cheating is acceptable may believe the reason for this is that sometimes students are unaware they are cheating, there is not enough time given for assignments, or that the information is too much for the course.

It may be difficult to accomplish, but cheating can be prevented. Teachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test?takers out in a room, to expelling(驅(qū)逐) a student, which will most likely hinder their plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self?esteem. Another simple way to avoid cheating is to create many different kinds of the same test. This prohibits(阻止) students from getting the answers off of a neighbor's test, but students still have the option of using other cheating tactics.

There may be a million ways to cheat and get away with it, but there are few times, if any, that it is justified. Cheating never has to be a necessity and it is never worth compromising morals and losing years worth of working towards a degree. This problem is spreading throughout America; with everyone's help, it can be stopped.

1.Which is the best title of this passage?

A．To cheat or not to cheat

B．Show your opinion on cheating

2.The second paragraph mainly tells us that ________.

A．cheating through the Internet is the most basic way

B．students who cheat in exams are cleverer

A．they don't understand their teachers' words

B．they bury themselves in a lot of homework

C．they don't have enough time to complete the study tasks

D．they forget to look over the material

4.What does the underlined word “hinder” in Paragraph 4 mean?

A．Prevent. B．Benefit. C．Confuse. D．Protect.

5.What is the author's attitude toward cheating?

A.It is reasonable. B．It is necessary.

C．It can be praised. D．It must be prevented.
