【难题27】阅读理解。请阅读下面短文，根据短文内容从每小题所给的A、B、C、D四个选项中选出最佳选项。
Most parents hope that their children can be happy and successful. But do you know the most powerful way to
encourage them to be so? The answer is to allow them to make their own decisions.
Different people have different ideas about children’s decision making. Unfortuna tely , most parents make decisions for their children—what they wear,what they eat and what movies they watch. In fact, it’s not good for children’s growing.
Children should be allowed to make decisions when they are very young. But this doesn’t mean th ey are allowed to do everything. For example, you shouldn’t take your children into a convenience store and tell them they can have anything they want. They would be overwhelmed(不知所措的) by the choices. But you can give them a choice among snacks. When children get older, expand (扩大) the number of choices you give them. For example, allow them to decide the activities they want to take part in or when they decide to go to bed.
The next step is to get your children to think before they act. Ask themselves several important questions. First, why do I want to do this? Second, what are my choices? Third, what are the results of the actions? After the three questions, they are sure to have right decisions.
1. The best way to make children happy and successful is to ____________ .
A. help children go to college
B. make children read more books.
C. allow children to buy more books
D. allow children to make their own decisions
2. What’s the writer’s opinion on children’s decisions?
A.Parents should allow children to make decisions.
B.Children could do what they want to do.
C.Children could not make decisions for children.
D.Parents should make decisions for children.
3. Parents should _________ when their kids are older according to the passage.
A. take their kids to the store
B. do everything for the ir kids
C. take their kids to take part in activities
D. give them more chances to make decisions
4. From the passage we can learn ________ .
A. all children like snacks in the store
B. few parents make decisions for their children
C. the kids can learn about how to make decisions
D. the passage wants to tell the kids how to be successful
【答案】
1.D
2.A
3.D
4.C
2.A推理判断题。根据第二自然段的描述可知作者认为父母应该允许孩子们自己做决定，故选A。
3.D细节理解题。根据文中信息When children get older, expand (扩大) the number of choices you give them. 可知随着孩子们的年龄增大应给他们更多的选择机会，故选D。
4.C推理判断题。通过这篇文章我们可以知道孩子们能够学会怎样做决定，故选C。

2015年中考化学走出题海之考前必做难题30 题 参考答案与试题解析 一、选择题（共17小题，每小题3分，满分51分） 1． 解答：解：由于碳酸钙高温分解生成了氧化钙和二氧化碳，随着碳酸钙的分解放出了二氧化碳，碳元素的含量逐渐减少直到为零．由题意可知，碳酸钙中钙元素与碳元素的质量比为40：12=20：6，剩余固体中钙元素与碳元素的质量比为20：3，则已分解的碳酸钙占原碳酸钙的质量分数为50%，所以，D正确，A、B、C错误． 故选D． 2． 解答：解：某H 2 O 2 溶液中H、O的质量比为2：17； 则：19g 双氧水溶液中氢元素质量为：19g×=2g 根据过氧化氢分解的化学方程式可以知道，过氧化氢完全反应后生成水和氧气，该过程中氢元素的质量没有改变；所以反应后水的质量为： 2g÷×100%=18g 所以根据质量守恒定律可以知道生成氧气的质量为 19g﹣18g=1g； 故选A．
3．解 答： 解：A、由流图可知固体b为铁，故A正确． B、操作①中玻璃棒的作用是引流，②中玻璃棒的作用是搅拌．故B正确． C、滤液a中含有硫酸亚铁、硫酸锌和硫酸3种溶质，故C正确． D、固体a中含有锌，c是硫酸锌，滤液a中含有硫酸锌，b中含有硫酸锌．故 D错误． 故选：D． 4． 解答：解：A、物质甲、乙分别为硫酸、硫酸钠，含有相同的硫酸根离子，相互间不能发生反应，不满足题中的转化关系，故A错误； B、物质甲、乙、丙分别为氯化钾、碳酸钾、氢氧化钾，含有相同的钾离子，相互间不能发生反应，不满足题中的转化关系，故B错误； C、物质甲、乙分别是碳、水，碳和水之间不会发生反应，不满足题中的转化关系，故C错误； D、物质甲为铁可与物质乙氯化铜、丁盐酸反应置换反应，物质乙为氯化铜可与甲铁、丙锌两种金属发生置换反应，物质丙为锌可与乙氯化铜、丁盐酸发生置换反应，物质丁为盐酸可与甲铁、丙锌两活泼金属发生置换反应，物质丁盐酸可与氧化铜反应生成乙氯化铜，满足题中的转化关系，故D正确； 故选：D．

In the 19th century, many people were interested in science and inventions. Jules Verne wrote about scientific subjects in his stories and, as a result, they were very popular. Verne's writing included many predictions（预言）for the 20th century and many of them came true. He described space flight, movies, and air conditioning, a long time before they appeared. These books were very successful and they made Verne rich. Jules Verne's books have been the subjects for many movies. 20, 000 Leagues under the Sea was a successful movie for Walt Disney.

They're digging, cutting leaves and planting new seeds（种子）. By summer, their gardens will be full of bright colors. The British love their gardens. A British newspaper recently asked people for their opinions about them. Around 70% of the people felt it was important to spend time in the garden, and over 50% of these described gardening as the most enjoyable thing they ever did. Only one in ten houses in Britain do not have a garden. People who live in houses without gardens often rent（租用） land from the government. At first, only very rich people had gardens. You can still see the gardens around houses with a long history, such as Chatsworth House or Castle Howard. In the early twentieth century, however, gardening became a hobby. People bought different kinds of seeds and plants for their gardens. Although roses, sunflowers and tomatoes are often grown in British gardens, they originally（起初） grew wild in other countries. Every year, there are competitions for the largest vegetables, but don't expect to win：Britain's biggest carrot is almost six metres long. （1）In summer, British gardens are often . A. covered with grey leaves and plants B. colorful with different plants C. too hot for people to work there D. full of people digging there （2）A recent survey showed that of the British felt it important to do some gardening.

走出题海：聚焦地球运动规律
走出题海：聚焦地球运动规律 聚焦之一：千姿百态的经纬网线判断问题 经纬网线因视角的不同而形状不同从而衍生出千姿百态的经纬网线增加了判读难度。判读经纬网线的关键在于沿着经线、纬线将“变形”的经纬网线还原到平时熟悉的形状。这项能力的培养关键在于平时的训练对经纬网线应从立体的角度去看而不是简单地将其看成平面图。 例1、【浙江宁波市2011年第二学期八校期初测试高三地理】若图中线段ac为地球表面的一半圆弧。回答1—3题。 8 小时前上传 下载附件(6.66 KB) 1、若线ac位于同一经线圈上新年伊始a点的正午太阳高度正好达90°则 A、a点比c点的线速度大 B、a、c位于同一纬线上 C、a与c的纬度值相等 D、a、c可能在同一经线上 2、若线ac位于晨昏线上a点的地方时为8时则 A、a点昼长大于c点昼长 B、c点日出的地方时是4时 C、太阳直射点位于北半球 D、a点的区时一定比c点的区时早12小时 3、若线ac位于70°N纬线上且6月22日晨昏线与a点的距离最近时下列说法错误的是 A、a点的太阳高度为3.5° B、c点的正午太阳高度为43.5° C、a点处于极昼 D、c点的正午太阳高度达一年中最小值 【解析】线段ac为地球表面的一半圆弧却表现为一段线条说明视角与该圆弧处于同一水平面解题时应将其转化为平时常见的侧视图、俯视图。 8 小时前上传 下载附件(40.69 KB) 第1题、将图转化为侧视图图1读图1可知a、c的纬度值相等虽不在同一纬线上但其线速度亦相等A、B选项错误C选项正确。a、c分属于不同的两条经线D选项错误。 第2题、由a点的地方时为8时推断a点在晨线上因晨昏圈为大圆故弧abc两端a、c位于同一经线圈的两条经线上且a、c两点的纬度值相等。据此将图转化为侧视图图2图3图中阴影表示

中考英语阅读理解难题及答案
中考英语阅读理解难题及答案 一、初三英语阅读理解（含答案详细解析） 1．根据短文内容选择正确答案。 D If you could see a movie of your life before you lived it, would you want to live it? Probably not. The excitement of living is that you don’t know what’s coming. Sure, it’s hard to see unce rtainty in such positive（积极的）light when you’re out of work, or when you feel like you’re failing. But uncertainty is really another word for chance. When Allison graduated from Harvard, she had chan ces all over the place but had no idea what she wanted to do. She took a job in consulting（咨询）, but she knew she wouldn’t stay there. She took the GRE and scored so high that she was able to increase her income（收入）by teaching students. Still, she didn’t think she wanted to go to graduate school. Allison kne w she wasn’t doing what she wanted, but she didn’t know what she wanted. She worried. All her friends were going to graduate school or starting their own businesses. She was lost and felt that she would never find anything out. After six years, Allison, by having a general（全面的）plan in mind, got married, moved to the Midwest, and used her consulting experience to get a great job. Allison realized that she spent her years finding her way: time well spent, and time we must all take if we’re being honest wi th ourselves. The only way to lead an interesting life is to face uncertainty and make a choice. Otherwise your life is not your own—it is a path someone else has chosen. Moments of uncertainty are when you create your life, when you become who you are. Uncertainty usually begins with a job hunt, but it doesn’t end there. Every new role we take on means another round of uncertainty. Instead of fearing it, you should find some ways to deal with uncertainty. （1）From the first two paragraphs, we can learn that . A. being out of work is a sad thing B. uncertainty is what makes life interesting C. life in a film is more exciting than real life. D. chance never appears when we need it （2）What troubles Allison after graduation? A. She couldn’t find a well-paid job. B. She had no money to start a business. C. She was not sure what to do. D. She didn’t score high enough for graduate school. （3）How did Allison feel about her six years’ working experience? A. Uncertain. B. Amazed . C. Sorry. D. Satisfied. （4）What may be discussed in the following paragraph? A. How to deal with uncertainty. B. What role uncertainty plays in life.
