绪言第一、二单元知识点复习题知识点1：什么是化学？1. 通过化学学习，我们知道化学在人类社会开展中起着重要的作用。

请你分析以下四个选项里面化学学科不涉及的研究领域是〔〕A. 开发新的能源B. 合成新的物质C. 空间形式和数量关系D. 防治环境污染2. 在一些科普读物中常见以下语汇，其中跟相关物质的颜色没有必然联络的是〔〕A. 蓝色固体B. 黑色粉末C. 绿色食品D. 白色烟雾知识点2：物质的变化1：化学变化的本质特征是〔〕A. 发光、放热B. 有气体或者沉淀生成C. 物质颜色发生变化D. 有其他物质生成2：以下变化中，与其他的变化不同的一项是哪一项〔〕A、葡萄酿成酒B、冰雪融化C、湿衣服晾干D、瓷碗破碎3：某固体物质受热后变为气态物质，这种变化属于〔〕A. 化学变化B. 可能是物理变化，也可能是化学变化C. 物理变化D. 既不是物理变化，也不是化学变化知识点3：物质的性质1、物理性质：物质不需通过化学变化就表现出的性质。

包括：颜色、状态、气味、熔点、沸点、密度、硬度、溶解性、挥发性、延展性、导电性、吸水性、吸附性等。

2、化学性质：物质在化学变化中表现出来的性质。

可燃性、氧化性、复原性、活泼性、稳定性、腐蚀性、毒性、金属活动性等。

3、它们的区别是：物质的物理性质在静止状态中就能表现出来，而物质的化学性质那么要在物质的运动状态中才能表现出来4、物理变化、化学变化、物理性质、化学性质之间的联络。

联络：在变化语句中加“能〞或者“可以〞或者“易〞“会〞“难于〞等词语，变成了相应的性质。

1. 以下各物质的性质中，属于化学性质的是〔〕A. 氢气的密度最小B. 浓盐酸有挥发性C. 一氧化碳难溶于水D. 二氧化碳不燃烧也不支持燃烧2. 以下描绘哪些是物理变化〔〕哪些是化学变化〔〕哪些是物理性质〔〕哪些是化学性质〔〕A、铜绿受热时会分解；B、纯洁的水是无色无味的液体；C、镁带在空气中燃烧后变成了氧化镁；D、氧气不易溶于水且比空气密度大；E、木棒受力折断。

A’s and B’s were a kingdom I could never enter.Once my teacher, Miss Mills, had given me a list of ten spelling words. My mother and I went over the list until I knew those words. I felt great. I thought, “Wow! This time, I’m going to pass”. The next day, I went into the classroom and began to write down the words. The first word was carpet. I wrote that one down: c-a-r-p-e-t. I was feeling pretty confident. Then came neighbor--I wrote down the letter n. Then rhythm--I knew there was an r. Suburban--I wrote s-u-b. My confidence failed me. I had gone from 100 percent to maybe a D-minus. Where did the words go?Some people talk about information sliding off your brain. That was my life. I was an underachiever (未能充分发挥学习潜力者).Now I know I have dyslexia (诵读困难症). A person with dyslexia might see the as teh, andbird as brid. My brain learns differently. A learning disability can really change the way you feel about yourself. Now I know that even if I learn differently, I can still be filled with greatness.Today when I visit schools as an actor, director, and co-author of children’s books, I tell children that everyo ne has something special inside. It’s our job to find out what that is and get it out, and give it to the world as a gift.( ) 1. What’s the writer’s problem in grade school?A. He had trouble spelling.B. He often got C-minuses.C. He was absent-minded.D. He had a physical disability.( ) 2. From Paragraph 2, we can infer that the writer __________.A. wrote down 20% words correctlyB. knew he had dyslexia thenC. felt upset about himself at lastD. studied hard and passed the test( ) 3. The underlined phrase “sliding off” in Paragraph 3 probably means __________.A. coming intoB. going throughC. moving aroundD. disappearing from( ) 4. After the writer knew he had dyslexia, he __________.A. felt very excitedB. had more difficulties in studyC. was filled with sadnessD. changed his view of himself( ) 5. What would be the best title for the passage?A. A Change for SureB. A Great UnderachieverC. A Gift from the WorldD. A Special Spelling Bee四、短文填词On 28 1 [mɑːtʃ], millions of people around the world switched off their lights to mark Earth Hour. Earth Hour is an annual(一年一度) event that brings 2 [əˈtenʃn] to the climate change. It’s run by the World Wildlife Fund (WWF), 3 organization that protects wildlife and the environment. People are encouraged to turn off the non-essential(不必要的) lights for an hour, 4 8:30 pm to 9:30 pm. It’s about giving people a voice on the planet’s future and 5 (work) together to create a better environment.Sydney Opera House was not the only landmark to turn off its lights this year.
