I was punished once while I was at school. That was only because I forced to do something I didn't want to do it. I got punished because of the boy, who I was really frightened for. One day, he told me he will be sitting behind me. I was asked to move my paper so that he could read that I'd written. I did as he said, but we were all caught cheating. I had to write a composition about honest. Learning what had happened, my head teacher criticized me or encouraged me to be trustworthy. I can hard forget the experience.
Now at some level, all moms and dads know they shouldn't yell at kids. But if you don't _______or talk angrily, how do you discipline（管教）？

Instead of _______, “Don't go near the water!” Inuit parents take a unique _______ and tell kids a special story about what's inside the water. _______, those stories seemed to me too scary for little children.

Summer is fast approaching and warmer temperatures bring pests like mosquitoes.
1. An easy way to protect yourself from mosquitoes is to use a repellent（驱虫剂）.Joseph Conlon, technical advisor of the American Mosquito Control Association, recommends using a repellent that is registered with the EPA （Environmental Protection Agency） , which promises that it causes no harm to humans. 2. Repellents with 25 — 30% concentration of DEET （避蚊胺）will provide 4一6 hours of protection and it is the “gold standard by which all repellents are judged," according to Conlon.
3. Conlon explained that mosquitoes can bred （繁殖）in water collected in areas as small as bottle caps but they have a limited flight range, meaning they can’t travel far. "The best way to avoid them is to not have them around in the first place, he explained. "If you've got them in yor backyard, it's because you're breeding them in your backyard."
Is there anything better than “the gold standard"? Repellents made from coconut（椰子） oil work better than DEET, a government study says. 4. A slight wind from a fan can help keep them at Bay.
If you have water around your house. Beth Ranson, public relations officer for Florida Keys Mosquito Control District, suggests acquiring fish that will eat mosquito larvae（幼虫）.
5.She and her team experimented with male mosquitoes infected with bacteria that stop females from producing larvae when they mate. "There's not a lot of companies producing new chemicals or treatments that we can use, she explained. " We need new technologies and products as these mosquitoes develop this resistance.
A.They can bring deadly diseases.
B.Mosquitoes are also weak fliers.
C.It is not suitable from children under three.
D.You can wear protective clothing and keep your windows closed.
E.Another key is to get rid of all the standing water every five days.
F.The repellent is also guaranteed to provide at least two hours of protection.
G.Ranson also started to find high-tech solutions to growing mosquito populations.
The popular streaming service Netflix announced plans to exclude (排除) tobacco use from any of its new shows and movies that target younger audiences, specifically those below the age of 15. According to media reports, the decision comes from pressure from Truth Initiative, a large non-profit organization aiming to get rid of tobacco and make its use “a thing of the past”.
Smoking is a bad habit and no parents want their kids to start smoking. As such, excluding the vice (坏习惯) from television shows and movies young people watch makes good sense. I’ll acknowledge that Netflix’s decision to exclude smoking is a good one — but it’s a wildly inconsistent standard. What about other vices? For example, the use of bad language?
As parents of three young boys, my wife and I are trying to expose our children to good things. We want to encourage them to grow up to become responsible men who see the value and potential in every person. We want to see them avoid the landmines that so often entrap young people today.
Sadly, typical television shows and movies contain material that’s the exact opposite of that. It’s often said that companies only produce what people will consume — and there’s some truth in such a claim. But the organization I work for has long had an online site that helps parents know about what's in a movie, show or music album. We don’t tell you whether you should watch or listen — we simply let you know what it’s about — and let you decide. It’s our most popular site, attracting millions of visits each month.
Netflix might be surprised how many new customers they would win if they started producing content that parents actually want instead of themes that regularly stand in opposition to the values of the millions of moms and dads like me who want to see our kids accomplish more in life rather than simply avoiding the smoking habit.
1.Why did Netflix plan to cut smoking from youth-targeted content?
A.Because of appeals from parents.
B.Because of the influence of media reports.
C.Because of requests from young audiences.
D.Because of pressure from a tobacco control organization.
2.What are “the landmines” in Paragraph 3?
A.Bad habits. B.Comfort zones.
C.Unrealistic dreams D.Improper friendships.
3.What does the online site mentioned in Paragraph 4 do?
A.It teaches parenting skills.
B.It promotes youth programs.
C.It advertises movies and shows.
D.It serves as an entertainment guide.
4.What does the author think of Netflix’s decision to exclude tobacco use?
A.It is helpless.
B.It is far from enough.
C.It is against popular values.
D.It is a warning to tobacco makers.
In a world where nearly 6 million fingerprint records of government employees are stolen in one computer hack, and here millions of people are victims of identity theft every year, the next step in cybersecurity may well be mapping your brain.
Researchers at Binghamton University, State University of New York are working on a biometric system that records how your brain reacts to certain images. With a little more polishing, the scientists’ brainchild could become the way you get into a safe deposit box, your office or past scanners at the airport. It could replace the password for your online banking, your email or your social media accounts.
The started their project by measuring the brain waves of 30 subjects, The subjects were fitted with a cap that had 30 electrodes attached to it, and then shown various images and symbols—celebrity faces, words, pictures of food—on a computer screen in 200- millisecond bursts. The brain's reaction was recorded.
The idea is that every time a person needs to use a “password”, he or she goes through the same procedure, and the results are matched with their first-time reaction. If the “brainprint”' is compromised—like what happened with the fingerprint records—then the system is merely reset by running another set of images and collecting a different set of brain waves. “Even if that was stolen, you could just cancel it and record one to something else”, says professor Laszlo.
Laszlo and her team have shown that their system can be 100 percent accurate. So one of the more difficult parts of making the system practical already has been overcome. Now they're spending much time recording accurate brainprints with as few as three electrodes, which could make recording in the future as easy as wearing a pair of special glasses. They're also working with cheaper material and methods to see if they can bring the cost down.
1.What does the underlined word “brainchild” in Paragraph 2 refer to?
A.The brain function. B.The fingerprint record.
C.The biometric system. D.The online password.
2.Why were the images and symbols shown to the subjects?
A.To create their brainprints. B.To check the brain's reaction.
C.To match brainprints with pictures. D.To connect brain waves to electrodes.
3.What are the researchers doing with the program now?
A.Making it user-friendly. B.Improving its accuracy.
C.Recording more brainprints. D.Increasing the number of electrodes.
4.Which's the best the title of this passage?
A.Brain waves—the necessity of passwords B.Biometric systerm—the hope of cybersecurity
C.Brainprint—the future of passwords D.Fingerpint—the challenge of cybersecurity
