4.根据以下资料，回答103-106题。 　　The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported Wednesday．Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is covering small island nations and threatening to destroy the low-lying, densely-populated low regions around the globe. 　　The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences rising oceans．It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change (IPCC), according to the authors. 　　Rising sea levels are driven by two things: the thermal expansion of sea water, and additional water from melting sources of ice．Both processes are caused by global warming．The ice sheet that sits atop Greenland, for example, contains enough water to raise world ocean levels by seven meters, which would bury sea-level cities from Dhaka to Shanghai. 　　Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say．But up to now, there has been a puzzling gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans. 　　The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reunite the models with observed data．Using new techniques to assess ocean temperatures to a depth of 700 meters from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimeter-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC. 106 The rise in water levels is especially dangerous for small island nations and __.

9.Friends become a child’s chosen family. If his social life is going well, he gains confidence. If he has trouble connecting, it hurts and can make him feel sad and withdrawn and lonely.1.Help your child communicate. Naturally outgoing kids have an easier time expressing their interest in other children than shy ones do. But you can help build this skill through practice. Ask your child about his favorite games and toys. Praise him for specifics when he shows interest in other people:” You were so nice to let Roger talk about his little dog. I am proud of you.”2.Keep play short and sweet. Parents should keep early play date short, so no one gets too tired and everyone has fun. Schedule the next one soon after that, so kids can quickly build on their comfort foundation.3.Know your child. If your child is bossy, tale with him and agree beforehand on which toys will be shared and which ones should be put away because your child just can’t seem to share them. If you have a shy child, match him with a younger child so he has a chance to be the leader.4.Help your child help others. Encourage your child to be a better friend by helping him include others in play. If you see someone being excluded, don’t ignore it. This is an opportunity to work on your child’s ability to understand others. “Rachel is being left out. That must make her feel very sad. Can you think of a way to include her in the game?”5.Help your kids help themselves. If your child is the one who’s being ignored or treated badly,teach him to speak up.Which word can best describe a child who is good at connecting?

Passage One

Telephone, television, radio and the Internet help people communicate with each other. Because of these devices, ideas and news of events spread quickly all over the world. For example, within seconds, people can know the results of an election in another country. An international football match comes into the homes of everyone with a television set. News of a disaster, such as a flood, can bring help from distant countries. With in hours, help is on the way. This is because modern technology information travels fast.

How has this speed of communication changed the world? To many people, the world has become smaller. Of course, this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago, communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the oceans. In the seventeenth and eighteenth centuries, it took six

weeks for news from Europe to reach the Americas. This time difference influenced people’s actions. For example, a few battles in the war of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed. They would not have died if news had come in time. In the past, communication took much more time than it does now. There was a good reason why the world seemed so much larger than it does today.News spreads fast because of ______.
