物干Cyber (网络的) bullies, like any bully, want to feel power and control over their victim. Many kids live and breathe on the Internet. It is essential to how they see themselves and how they socialize with their peers. The computer is as essential a social tool today as the telephone was decades ago.This is part of why a cyber bullying attack can be disastrous. Targets are faced with threats and intimidation in emails and instant messages, but it is not only fear that the cyber bully can instill (灌输) over the web.The potential for public humiliation (羞辱) has been expanded from a target’s classmates or school to effectively the entire world, or at least the wired world. To be humiliated in front of a classroom of students is bad enough but to be humiliated for the amusement of thousands is more than most kids can bear.So, as parents, what should you do to deal with cyber bullying?First, do not respond to the cyber bully’s attacks. This is what the bully wants. They want you to engage with them. They want to manipulate you into responding. If you respond in any way that is emotional or lets them know that they are getting to you and are able to make you upset it only encourages the cyber bully.Second, report the cyber bullying to police and schools. You need to let appropriate authorities know about the cyber bullying or they cannot take corrective action. Cyber bullying is not something you want to ignore. It is your responsibility to report this behavior so the perpetrators (作恶者) can be dealt with. This helps to not only protect your child but to intervene before the cyber bully harms even more kids.Finally, be aware of what your child is doing on the Internet. It is vital to keep up with what is going on in your child’s world. More and more a large part of that world involves online activities and communication. You need to talk with them about what they are doing and with whom they are communicating.Cyber bullying can be every bit as dangerous as bullying; more so in some cases. Keep open communication lines with your children so they will feel comfortable enough to tell you. They need to know that cyber bullying is not their fault. The fault and the problem both lay with the cyber bully.1. Why can a cyber bullying attack be disastrous for kids?A) Because they can hardly escape from the harm of bullying attack from the Internet. B) Because they cannot see themselves and socialize with their peers any more.C) Because they haven’t expected that the fear of cyber bully will last so long.D) Because they have to use computers as an essential social tool.2. Why are parents suggested not to respond to the cyber bully’s attacks?A) Because that will just fall into the trap of the attackers. B) Because that will bring more harmful cyber bully attacks.C) Because that is too emotional and will let the attackers know what you are doing.D) Because that will make parents upset and thus engage with them.3. How to protect more kids from being harmed by cyber bullying?A) Work with other parents to take corrective action.B) Talk with cyber bullies about their dangerous behavior.C) Let appropriate authorities know about the cyber bullying. D) Participate actively in kids’ online activities and communication.4. What should parents do when their children become victims of cyber bullying according to the passage?A) Remind them that cyber bullying is as dangerous as bullying.B) Try to make them feel comfortable enough to ignore it.C) Limit their access to the internet.D) Tell them that cyber bullying is not their fault. 5. Which of the following could be the best title for this passage?A) The harmful effects of cyber bullying.B) Dealing with cyber bullying. C) How to avoid cyber bullying.D) Cyber bullies are bringing in more victims.物干

The first Antarctica Marathon on King George Island indicates that ______ .Passage One Sometimes a race is not enough. Sometimes a runner just wants to go further. That’s what happened to Dennis Martin and Brooke Curran. Martin, 68, a retired detective form New York City, took up running after his first wife died. Curran, 46, a philanthropist (慈善家) from Alexandria, started running to get out of the house and collect her thoughts. Both she and Martin got good at running but felt the desire to do more. "The more I trained, the better I got," Curran said, "but I would cross the finish line with no sense of accomplishment." Eventually, they worked up to running marathons (马拉松) (and longer races) in other countries, on other countries. Now both have achieved a notable---and increasingly less rate--- milestone: running the 26.2-mile race on all seven continents. They are part of a phenomenon that has grown out of the running culture in the past two decades, at the intersection of athleticism and leisure: "runcations," which combine distance running with travel to exotic places. These trips, as expensive as they are physically challenging, are a growing and competitive market in the travel industry. "In the beginning, running was enough," said Steen Albrechtsen, a press manager. "The classic marathon was the ultimate goal, then came the super marathons, like London and New York. But when 90,000 people a year can take that challenge, it is no longer exciting and adventurous .Hence, the search for new adventures began." "No one could ever have imagined that running would become the lifestyle activity that it is today," said Thom Gilligan, founder and president of Boston-based Marathon Tours and Travel. Gilligan, who has been in business since 1979, is partly responsible for the seven-continent phenomenon. It started with a casual talk to an interviewer about his company offering trips to every continent except Antarctica. And then in 1995, Marathon Tours hosted its first Antarctica Marathon on King George Island, off the tip of the Antarctic Peninsula: 160 runners got to the starting line of a dirt-and ice-trail route via a Russian icebreaker through the Drake Passage.A、international cooperation is a must to such an event B、runcations are expensive and physically challengingC、Marathon Tours is a leader of the travel industryD、adventurous running has become increasingly popular

Passage One Questions 46 to 50 are based on the following passage. We're eating more fish than ever these days. At around 20 kilograms per person global fish consumption is now more than twice what it was in the 1960s. What's really remarkable, though, is where that fish comes from. For the first time in human history, most of our aquatic(水产的) food now comes from farming rather than fishing. People ate around 73 million tonnes of farmed fish—just more than half of the volume of fish that humans consumed—in 2014. That's out of a total fish supply of 167 million tonnes; the remaining 20 million or so tonnes go into things like animal feed and medical products. To keep eating fish at the current rate, we're definitely going to need to keep aquaculture(水产养殖) developing. That's because the volume offish caught in the wild has leveled off since the 1990s. Back in 1974, only 10%of marine fish stocks had been overfished. Now, more than three-tenths are. Only a tenth of our oceans' fish stocks could sustain heavier fishing than current levels. But while catchings at sea have suffered, fish-farming has been growing at a fast rate. A lot of that is coming from China, which produces 60% of the world's farmed fish. In fact, some 35 countries, including China, now produce more farmed than wild-caught fish. This shift toward aquaculture isn't just good for ensuring salmon(三文鱼) on your plate; it's also crucial to ensuring food security and sustainability. By 2050, the world will need to feed an estimated 9.7 billion people. They'll have to get their protein somewhere. However, raising cattle, pigs, and other land-based animals requires vast sums of grain and water. For example, pound for pound, beef requires 15 times more feed to raise than carp, a freshwater fish farmed all over Asia. That grain-and the water needed to grow it-could be consumed by people instead. However, aquaculture is no silver bullet. In some southeast Asian countries, shrimp farming does disastrous damage to marine ecosystems. Despite these problems, however, shrimp continues to be among the most popular sea foods worldwide. 46. What does the author say is remarkable about the fish we eat?A) They reproduce quickly.B) They are mostly farmed.C) They have become as important as grain.D) They have a longer history than humans. 47. What do we need to do if we keep consuming fish at the current rate?A) Increase the fishing volume considerably.B) Develop more advanced fishing technology.C) Enlarge the marine fish stocks effectively.D) Expand the scale offish-farming continuously. 48. What does the author say about China in terms of aquatic food?A) It places increasing emphasis on fishing now.B) It boasts of the world's largest fishing stocks.C) It raises more fish than caught from the wild.D) It supplies 60%of the world's fish products. 49. Why does the author say aquaculture is so important these days?A) It is a must for feeding the world's fast-growing population.B) It proves a reliable source of protein for humans and animals.C) It is essential to maintaining both mental and physical health.D) It ensures a balanced healthy diet for people the world over. 50. What does the author imply by saying aquaculture is no silver bullet?A) Shrimp-farming is a risky business.B) Fish-farming will not be sustainable.C) Fish-farming may cause serious problems too.D) Shrimp-farming can become quite expensive.
