The books are in every language — new books, ancient books, 5____ a book on the history of Iraq that is seven hundred years old.She had asked the government for 6______to move the books to a 7_____place, but they refused.

Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金)(our kindergarten daughter is serious about becoming a doctor).For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with less need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball-simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.1.What do the words "more is more" in paragraph 1 probably mean?3 / 5A. The more, the better.B. Enough is enough.C. More money, more worries.D. Earn more and spend more.2. What made Georgia agree to sell some of her objects?A. Saving up for her holiday.B. Raising money for a poor girl.C. Adding the money to her fund.D. Giving the money to a sick mother.3. Why did the author play the ball with Shepherd?A. To try out an idea.B. To show a parent's love.C. To train his attention.D. To help him start a hobby.4. What can be a suitable title for the text?A. Take It or Leave ItB. A Lesson from KidsC. Live More with LessD.

寒假训练01 化学实验基础一、典题温故1.【答案】B【解析】柠檬烯不溶于水,密度比水小,因此当馏出液无明显油珠,澄清透明时,说明蒸馏完成,A正确;蒸馏结束后,先把乙中的导气管从溶液中移出,再停止加热,B错误;长玻璃管与大气相通,能够起到平衡气压,防止由于导管堵塞引起爆炸,C正确;得到的精油中含有其它成分,要想的得到柠檬烯,要进行萃取、分液、蒸馏操作才能实现目的,D正确;正确选项B。
二、经典集训1.【答案】A【解析】①用试管夹夹持试管时,试管夹从试管底部往上套,夹在试管的中上部,故①正确;②给试管中的液体加热,为避免液体沸腾时飞溅出来,液体的体积不能超过试管容积的1/3,故②错误;③不能把鼻孔靠近容器口去闻气体的气味,要用手轻轻煽,让少量气体进入鼻孔,故③错误;④将固体粉末倒入试管中时,把试管平放,用纸槽往试管里送入固体粉末,然后缓慢竖立试管,故④正确;⑤取用放在细口瓶的液体时,取下瓶塞倒立放在桌面上,倾倒液体时瓶上的标签对着地面,会使残留的液体腐蚀标签,应该标签朝着手心,故⑤错误;⑥将烧瓶放在桌上,用力塞紧塞子,容易把烧杯口弄破,这些玻璃仪器都是很脆弱的,塞塞子要慢慢的旋紧,故⑥错误;⑦坩埚钳可用于移走正在加热或很热的蒸发皿,是实验基本操作的要求,故⑦正确;⑧滴管垂直悬空,不能伸进试管内,会污染滴管,故⑧错误;⑨稀释浓硫酸时,应把浓硫酸沿烧杯内壁慢慢倒入水中,并不断搅拌,因为水的密度比浓硫酸小,如把水加入浓硫酸,溶解过程中温度升高容易引起液体飞溅,从而导致安全事故,量筒是量取液体体积的量具,不能用来溶解液体,故⑨错误;⑩检验装置的气密性时,把导管的一端浸入水中,用手捂住容器的外壁或用酒精灯微热,导气管口处有气泡冒出,松开手,导气管中上升一段水柱,证明气密性完好,故⑩正确;综上①④⑦⑩正确。
故选:A。
2.【答案】C【解析】A.量筒的感量为0.1mL,选100 mL量筒误差大,可选20mL量筒量取12.5mL 盐酸,故A错误;B.氢氧化钠具有强烈的腐蚀性,不能放在托盘上的纸片上称量,故B错误;C.需用220mL 1mol·L−1 CuSO4溶液,选择250mL容量瓶,CuSO4·5H2O晶体的质量为0.25L×1mol·L−1×250g·mol−1=62.5g,所以C选项是正确的;D.稀释浓硫酸时,一定要将酸缓缓加入到水中,不能将水加入到酸中,防止瞬间放出大量热,导致仪器炸裂,故D错误。

The first half-hour on the bike is free, but if you don’t return it after 30 minutes, you have to pay. But it’s only ?1 a day or ? 29 a year! The bicycles are heavy ( 25 kg), and they are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!Paris is not the first city to have a scheme like this. But not everybody thinks it’s a great idea. One Parisian said, “These bicycles are only for short journeys. If people want to travel across the city, they won’t use a bicycle —they’ll still use their cars.”A city spokesm an said, “The bicycle scheme won’t solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren’t any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so theproblems in our environment will get worse. The bikes might help people to lead a healthier life, too.”.1.What can we learn about the Velib scheme?A.Its bikes have no baskets.B.Its bikes are light and colorful.C.It aims to make traveling easier.D.It owns more stations than the subway.2.If you use a Velib for 1 hour, you should pay _____.A.-1B.-30C.-29D.no money3.Why do some people disagree with the Velib scheme?A.The cost is rather high.B.It's hard to find a Velib station.C.It's not suitable for a long journey.D.The distance between two Velib stations is long.4.What’s the city spokesman’s attitude towards the bicycle scheme?A.Positive.B.Doubtful.C.Uncaring.D.Worried.完形填空9、阅读下面短文,从短文后各题所给的四个选项(A、B、C和D)中,选出可以填入空白处的最佳选项。
