1．The evidence demonstrates how easily people can hold contradictory (相互矛盾的) beliefs.2．Was his mother too severe (严厉) on him?3．The driver of the crashed car received multiple (多样的) injuries.4．We should transform our subjective world while transforming (改变) the objective world.5．According to official statistics (统计数字)，the island had 37 people.6．The traffic accidents in the city decreased (减少) last year.7．They made substantial (重大的) changes to the arrangements.8．The prime minister was always demanding active intervention (干涉) early on.9．The police have now narrowed down their list of suspects (犯罪嫌疑人)．10．He was not displeased at the way he handled (处理) the problem.Ⅱ.阅读理解ABrian Greene, a professor of physics and mathematics at Columbia University, has created an online science education platform. He tries to “build a bridge” with things you know about, and then “bring you across that bridge to the strange place of modern physics”．Recently I had a chance to ask Greene about wormholes (a hole which some scientists think might exist, connecting parts of space and time that are not usually connected), time travel and other mysteries of the universe. I asked him a million­dollar question：W hat if I went through a wormhole and prevented my parents from meeting? “Most of us believe that the universe makes sense，” Greene said. Although there are several interesting theories about time travel, he added, the laws of physics would probably prevent something so illogical from taking place. The good news is that the time paradox (悖论) is open for future physicists to solve.When asked how physics could become more exciting for kids, Greene said that books by Stephen Weinberg, Leonard Susskind, and other physicists, “make it a great time for people who want to learn about big ideas but aren't yet ready，perhaps, to learn math. ”When I pointed out that some students still might find physics boring, Greene said that the key is to teach them about things that are strange. “The basic stuff is important，” Greene said. “But I think it's really important to also describe the more modern ideas, things like black holes and the Big Bang. If kids have those ideas in mind, then at least some of them will be excited to learn all the details. ”Greene has followed Albert Einstein's lead in trying to solve the mysteries of the universe. Now he wants kids to do the same. As Greene said, physics is “not just a matter of solving problems in an exam”. It's about experimenting, showing an interest in strange phenomena (现象)—and having fun!【语篇解读】本文是一篇说明文。

课时分层作业(十三) Section Ⅰ(建议用时：35分钟)[高考题型练习提能力]Ⅰ.阅读理解AJ. K. Rowling turned another year older this week. Born Joanne Rowling, J. K. Rowling is, of course, her adopted pen name. Concerned that young boys might not go for a book written by a woman, her publisher suggested she come up with a pseudonym(笔名). So, upon combining her first initial with the initial of her paternal grandmother, Kathleen, the moniker J. K. Rowling was born.That's the interesting fact about Rowling, apparently, and she can only fool some of the people some of the time.Back in 2013, a crime novel appeared on the shelves. It was entitled The Cuckoo's Calling, and it was written by Robert Galbraith. According to Galbraith's bio, he spent “several years with the Royal Military Police” and the leading character of his novel, a fellow by the name of Cormoran Strike, “grew directly out of his own experiences and those of his military friends.”Only, upon further review, he didn't! The book was actually penned by J. K. Rowling, who apparently wanted to try and sell a novel based on complete craftsmanship rather than on her name.Unfortunately, however, the wife of a partner in the media in whom she placed her trust, shared the secret on Twitter. Rowling was angry and disappointed concerning the betraying of trust.I'm not sure whether I would be terribly upset for too long，if I were her. Previous to her being known as the author，Rowling saw her book listed 4，709th on Amazon. After the big revelation, her book jumped all the way to No. 1!More importantly, I think she got what she wanted. The novel has received nearly universal critical acclaim. Rowling passed her own test with flying colors. Clearly, she's pretty good at her craft!In any case, I personally look forward to reading her newest writing endeavor.【语篇解读】本文主要报道了J.K. Rowling用其他名字写书这一秘密暴露一事。

课时分层作业(十三) Section Ⅰ[高考题型练习提能力]Ⅰ.阅读理解AListening to music is considered a good thing for adults.Indeed it is.Scientific studies have proved it.Music has so many good effects on our body，mind and mood that this world will certainly not be a good place without music.Then，is music good for children? Some parents think so and let their children learn or listen to music.But some parents don't know the importance of music to children.Here are some reasons why music is important to children.First，music is good for children's intelligence.Studies have proved that children who learn music are likely to have higher intelligence than those who have no interest in or dislike music.This is because the brain gets stimulated (刺激) by the rhythm and tone of music.Music also has soothing (抚慰的) effect on children and helps remove their stress.Today's children are under a lot of stress from schoolwork.Being under too much stress impairs children's health.Luckily，listening to music can help them feel better.Music can improve children's moods.Some children are sad by nature.They seem to be lost in their own thoughts and don't take interest in their surroundings.In such cases，a method known as “music therapy” comes to their rescue.It changes their moods and places a new kind of spirit in them.Music is also a universal language that children ought to learn.Our world has become a global village.People are getting more and more interested in other cultures and countries.Music can help them in understanding foreign cultures.Now we can say that music is very important not only to adults but also to children.So children should be encouraged to learn music or listen to music.【语篇解读】小孩接触音乐对他们很有好处，父母应该多让小孩接触音乐。

67 million pieces are housed in more than 200 museums in 47 countries,which accounts for 10 percent of all lost Chinese cultural relics，and the rest are in the hands of private collectors。

In some cases，private collectors donated the relics to the government。

Also the government can turn to official channels to demand the return of relics。
