3.根据下面一段文字,概括说明全球首张水渗透性地图的意义。
(不超过40个字)(4分)加拿大不列颠哥伦比亚大学的汤姆•格利森和他的同事完成了全球第一张显示地表渗透性的地图。
他们收集世界各地不同岩石的数据,通过每种岩石的渗透性信息计算得出该地区的渗透性。
它显示出水通过地表向下渗透的容易程度,这将有助于我们了解地球的水循环系统,并能对地下水资源的可利用程度进行预测。
格利森说,该图可以帮助计算出地下水从一片区域或含水层向其他区域的流动量,这对保护水资源可持续发展至关重要。
重要的是,这些水资源在预测气候变化时并没有成为考虑因素。
目前,我们并不能确定地下蕴含多少水资源,也不清楚这些水资源的分布。
因此,地下水并没有成为衡量气候变化的因素。
格利森说,这是个重大遗漏,因为地下水运动在很大程度上能影响区域气候。
4.仿造下面的示例,以“青春”为话题,再写两个句子。

While I was chatting to my grandmother about my busy day, my sister interrupted us wanting to know if we, too, could smell burning.As my parents were overseas, the thought of a fire terrified us and we quickly checked every room in the house. Nearing the lounge room, I could see a glowing light and hear a roaring sound. To my horror, the mantelpiece was ablaze and smoke was billowing out a window.I yelled to my sister and grandmother to get out of the house. My sister grabbed the phone to call the fire brigade and, together with the dog, we ran away from the house.While we anxiously waited for help, a lady and her young daughter ran towards us to check if we were hurt. She had noticed smoke coming from our window and had already alerted the fire brigade. She hugged us and was very relieved to see us safe.She led us to her car where we waited until the fire brigade had finished dousing the flames. She also helped us answer questions so the police could start their investigations.Once the lady was convinced that some order had been restored, she apologized for not being able to stay longer, as she had to take her daughter to a dance performance. She promised to return later to check in on us.I was completely lost for words. This kind lady had gone out of her way to make sure we were safe and now she was apologetic about leaving us. We thanked her profusely and urged her not to delay any further.Hours later, we were allowed back into the house. It was about midnight when the doorbell rang. To my disbelief, it was the lady from earlier at the door.As promised, she’d returned to check on us. She was relieved that we all were settled and gave us a warm hug before leaving.Unfortunately, in all the commotion, I didn’t ask her where she lived so my family hasn’t been able to thank her properly for her thoughtful actions that day.56. The thoughtful lady was most probably ____.A. a neighborB. an onlookerC. a passer-byD. a firefighter57. What does the underlined word “douse” mean?A. put outB. put awayC. coverD. fan58.

My Terrible ExperienceC. What a Terrible FireD. Warm Glow From a FireBIn this age of the importance placed on human liberties, the idea of forcing someone to do something he does not want to do may receive condemnation. In my opinion, forcing should be resorted to only when all persuasion fails.Forcing a child to brush his teeth is quite sound. That is if all else fails – educating him about tooth decay, using a carrot and stick approach and even buying him an electric toothbrush. It is very important that he brushes his teeth and he is a child. Children have to be taught what’s good and bad and be trained too.In choosing a secondary school, a twelve-year-old may not have the maturity to weigh the pros and cons involved. If the child does not want to study in the school of his parents’ choice, he may have to be persuaded. Otherwise the issue may be thrashed out and the parents firmly, but gently lay down the rule. Children do not have the experience of life and the foresight to make major decisions that affect their lives. It is important though that parents, should they force, do so carefully and sensitively. Children cannot do without their parents or guardians watching over them.In school, teachers and principals are given the authority to make the students do what is to be done. A teacher expects submission to his or her commands. In detention classes, students are made to do unpleasant tasks as a punishment.On the other hand, adults shouldn’t be forced to do things against their wishes. They are autonomous, no longer under their parents’ control. They have been through much of life and have trained by parents and teachers through childhood and adolescence. Now they are independent and know what they want and what they do not want. They should be guided and advised, not forced.Thus, depending on the circumstances, children can be forced to do things which they prefer not to do. Adults, on the contrary, should not be.60.

Here are a few tips and tricks to prevent you becoming overwhelmed.* Set aside time to read your incoming emails at certain times of the day.* To avoid being interrupted by incoming emails, deactivate the function telling you an email has arrived (usually a sound alert), or turn the volume right down so that the chime or sound can’t be heard.* Make the most of your anti-spam settings (or get your Information Technology [IT] team to set them up for you).* Make sure your computer software is up to date, including anti-virus filters. If you’re not sure how to load up or activate anti-virus filters, find out by goingonline, or seek professional support.* Make sure your Internet Service Provider (ISP) is dealing with as much spam as possible and check the anti-spam settings on your computer.* Sort incoming emails quickly, deleting as you go (always delete emails withattachments from unknown senders).* Limit the use of your primary email address to avoid being flooded with spam (and jokes). Set up two addresses: one for work-related email and the other for staying in touch with friends.* Unsubscribe from e-newsletters you don’t have time to read.* Downloading emails on a mobile phone or PDA can take a long time, but some smart phones now compress emails before they hit your inbox. This saves time, especially if pictures or documents are attached.* If you need a quick reminder to do something when you get home, send yourself an email from work.64.

The number rose from less than 30 percent in 1970 to 45.5 percent in 2008.Young adults are also delaying marriage and starting a family. In 1970, the median age for a first marriage was 20.8 for women and 23.2 for men, compared to 25.9 for women and 28.1 for men in 2009.“Some research suggests that the notion of adulthood is changing and that marriage and parenthood, once the hallmarks of adult status, are no longer as important to defining a successful transition to adulthood,” Wight said.“Others have argued that changes in values and attitudes have contributed to rising individualism. So, we are less willing to get married,” she added.American Indians and Alaskan native communities had the highest percentage of young adults who were not financially and economically independent.“Relative to other race / ethnic groups, they have historically suffered from poor employment opportunities within their community, higher unemployment rates, and range of factors such as high rates of depression,” she said.Wight believes that a public policy approach can help ameliorate (改善) thelong-term impact of young disconnection.“We need to focus on keeping children and youth on track to be connected in young adulthood… And we need to focus on reconnecting those who fall off the track and fail to launch.”67.
