阅读下面的句子，根据文章内容进行判断，正确写“T”，错误写“F”。Stop Yelling At Your KidsParenting is hard. If you’re a parent, I’m sure that I don’t need to tell you that our job is a tough one. When youre managing children, it can be difficult to remember that they are still learning. If you find yourself yelling at your kids more often than you want to, here are some ways that can help you reduce the yelling. I’ve been working on this for the past few months and I have to say,it’s been amazing for both the kids and me.If you are having an argument with your child, you need to make sure you both take the time to really listen. It gives both of you time to think and really listen to each other, which is important. Kids are more likely to listen to you if you listen to them!One of your biggest struggles is to remind yourself of appropriate expectations. You can’t expect that your youngest acts as responsibly as your oldest. You should lower what you expect -taking into consideration things like their age - it can make a big difference. You should do your best to take a moment before yelling and take in a deep breath. It makes a world of difference for you. Instead of yelling, you’d better whisper. It can also help diffuse any situation by making things quieter, not louder. Besides, the more time you spend with your kids, the better you’ll get at communicating with them. You’re both more likely to understand each other.If your children aren’t listening or it seems they only don’t listen to you, you don’t take it personally. You should remind yourself that your kids are still learning and they’re not going to be perfect.( )21. As a parent, you may know that parenting is an easy job.( )22. Listening to each other is a good way to stop argument between parents and their kids.( )23. Usually younger kids behave less responsibly than elder children.( )24. Parents should lower their expectation for their kids.( )25. Both yelling and whispering can help make things quieter.

第三篇Cheating is when a person misleads,deceives,or acts dishonestly on purpose.For kids,cheating may happen at school,at home,or while playing a sport.A new study finds that most high school students say they have cheated on tests and homework.This study showed that 89 percent said glancing at someone else's answers during a test was cheating,but 87 percent said they'd done that at least once.Also,94 percent said providing answers to someone during a test was cheating,but 74 percent admitted to doing it.Cheating can happen in a lot of different ways.You can do it by sneaking answers to a test,but it's also cheating to break the rules of a game or contest or to pretend something is yours when it isn't. When people cheat,it's not fair to other people,like the kids who studied for the test or who were the true winners of a game or contest. If students today want to cheat,they have a more insidious tool at their disposal:cellphones.More than one third of teens with cellphones admit to having stored information on them to look at during a test or texting friends about answers.Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can't pass the test without cheating. Even when there seems to be a "good reason"for cheating,cheating isn't a good idea. Kids who cheat may feel worried about getting caught.Whether they are caught or not,these kids may feel guilty,or embarrassed,or ashamed,or all three.Teachers can ban cell phones in exams and principals can suspend or expel students who cheat,but it's important to know if students continue to cheat they will have a lot of problems in the future.What does the word"sneak"refer to?A:Write down.B:Offer.C:Bring in a secretive manner.D:Provide.

The Benefits of Lifelong Learning for AdultsLifelong learning is the process of keeping your mind and body engaged一at any age一by actively pursuing knowledge and experience.In fact,it has many benefits.Firstly,it keeps the mind sharp and it improves the memory.Secondly,it improves self-confidence and offers an opportunity to try something new. Thirdly,it gives the learner the feeling of accomplishment. Also,it offers the learner the opportunity to keep in touch with people who share with him/her the same interests and make new acquaintances.Finally,it offers an opportunity to learn a new skill or trade.Achieving retirement means having a lot of spare time and becoming more stressed and bored. However,some adults think that learning at that age is a way to get rid of this situation of boredom and stress.For them learning should be a lifelong process and even retirement should be an opportunity to try new things rather than being passive and pessimistic.Lifelong learning helps you remember things better.A:Right B:Wrong C:Not mentioned

第三篇Internet Helps Families Stay More in TouchMuch has been said about how anti-social the Internet and mobile phones are.The truth is however,according to new research,communication technology is bringing people closer together. A study by the Pew Internet and American Life Project found family members were keeping in regular contact today more than ever before. And this is all down to e-mail,chat,our cellphones and SMS messaging. It makes sense.Years ago,it took a long time to write a letter,then find an envelope and go to the post office to buy a stamp and post it.Today we write mails while we wait for our change in the convenience store and they're sent in an instant.Having free Internet telephone calls also helps us to stay in touch more often and for longer. Everyone's using it,from five-year-olds to tech-savvy grandparents.According to the Pew survey,technology has a very positive effect on communication within families.Researchers asked 2,252 adults whether new technologies had increased the quality of communication with their family. Fifty-three percent said it increased communication with family members they did not live with,two percent said technology decreased this.Numbers were similar for those living in the same house as their family.The project director Lee Rainey said:"There's a new kind of connectedness being built inside of families with these technologies."Survey co-author Barry Wellman agreed:"It used to be that husbands went off to work,wives went off to a different job or else stayed home…and the kids went off to school…and not until 5:30 or 6 o'clock did they ever connect,"he said.What does the verb"tech-savvy"mean?A:Being frightened by new technology.B:Knowing a lot about technological things.C:Knowing little about technological things.D:Being indifferent to new technology.

Losing WeightGirls as young as 10 years old are dieting and in danger of developing unhealthy attitudes about weight,body image and food,a group of Toronto researchers reported Tuesday.Their study of 2,279 girls aged 10 to 14 showed that while the vast majority had healthy weights,nearly a third felt they were overweight and were trying to lose pounds. Even at the tender age of 10,nearly 32 percent of girls felt"too fat"and 3 1 percent said they were trying to diet.McVey,a researcher at the Hospital for Sick Children in Toronto,and her colleagues analyzed data collected in a number of surveys of southern Ontario school girls between 1993 and 2003,reporting their findings in Tuesday's issue of the Canadian Medical Association Journal.Nearly 80 percent of the girls had a healthy body weight and only 7.2 percent were considered overweight using standard weight-to-height ratios.Most researchers suggest the rate of overweight children in this country is several times higher than that figure.Nearly 30 percent of the girls reported they were currently trying to lose weight,though few admitted to dangerous behavior such as self-induced vomiting.Still,a test that measured attitudes towards eating showed 10.5 percent of survey participants were already at risk of developing an eating disorder."We're not talking about kids who've been prescribed a diet because they're above average weight or overweight. We're talking about children who are within a healthy weight range.And they have taken it upon themselves to diet to lose weight,"McVey said,acknowledging she found the rates disturbing. She said striking a balance between healthy weights and healthy attitudes towards food and body image is a complex task,with no easy solutions. The study showed that most of the girls______.A: were overweightB: were on a dietC: had unhealthy attitudes about weightD: had a healthy body weight
