四、阅读理解（共15小题，每小题2分，满分30分）

The two friends -- Sevareid, 17 and Port, 19 -- had to shout in each other's ears to be heard over the noise of the rushing water. They were moving fast in a boat. To the left and right were cliffs（悬崖）.

Before the boys had left their homes in Minneapolis, Minnesota, on June 17, 1930, their families had tried to talk them out of the dangerous trip. But the boys were determined. They would start at their homes near the Mississippi River and paddle their boat to Hudson Bay, a distance of more than 2,000 miles.

Sevareid and Port had never traveled by boat before and knew very little about life in the woods. But as they neared the end of their four-month journey, they had learned many lessons firsthand. They had endured(忍耐) cold rain, icy winds, and

sleepless nights. They were nearly out of food like sugar and hardtack, a kind of hard biscuit. They could, however, catch fish they wanted. But the days were getting shorter, and they had to pay attention to getting to Hudson Bay before the winter freeze set in.

As they neared the end of their adventure, Sevareid and Port realized that the challenges of survival in the wild made the difficulties of ordinary life seem small.

In October 1930 they returned to Minneapolis. They had traveled more than 2,000 miles down rivers and across lakes and had faced many difficulties and dangers. They discovered the trip had changed them. Sevareid, who later became a famous reporter, said, “It was as though we had suddenly become men and were no longer boys.”

56. How long had they traveled?

A. Less than 2,000 miles.

B. More than 2,000 miles.

C. Less than 1,500 miles.

D. More than 2,500 miles.

57. What does the underlined word “determined” mean?

A. Becoming better.

B. Making a firm decision.

C. Feeling afraid that something bad might happen.

D. Making something clear.

58. Paragraph 3 is mainly about _________.

A. how Sevareid and Port had trouble sleeping at night

B. what Sevareid and Port ate while they were on their boat

C. what might have happened to Sevareid and Port

D. the difficulties Sevareid and Port faced on their trip

59. Which is TRUE according to the passage?

A. Sevareid and Port ate only fish on their trip.

B. Port later became a famous reporter.

C. Sevareid and Port had traveled by boat a few times before.

D. Sevareid and Port’s families didn’t allow them to take the dangerous trip first.

60. The writer probably wrote this article to ________.

A. warn young people not to do things like the two boys

B. encourage young people to travel across the country

C. tell the readers a dangerous trip shared by two boys

D. explain what would be helpful on a long boat trip

And now I know the end is better than the beginning, for my children can walk alone."

The power of positive thinking

A man once telephoned Norman Vincent Peale. He was despondent and told the reverend that he had nothing left to live for. Peale invited the man over to his office. “Everything is gone, hopeless,” the man told him. “I’m living in deepest darkness. In fact, I’ve lost heart for living altogether.”

Norman Vincent Peale smiled sympathetically.

“Let’s take a look at your situation,” he said calmly. On a sheet of paper he drew a vertical line down the middle. He suggested that they list on the left side the things the man had lost, and on the right, the things he had left. “You won’t need that column on the right side,” said the man sadly. “I have nothing left.”

Peale asked, “When did your wife leave you?”

“What do you mean? She hasn’t left me. My wife loves me!”

“That’s great!” said Peale enthusiastically. “Then that will be number one in the right-hand column--- Wife hasn’t left. Now, when were your children jailed?”

“That’s silly. My children aren’t in jail!”

“Good! That’s number two in the right-hand column——Children not in jail,” said Peale, jotting it down.

After a few more questions in the same vein, the man finally got to point and smiled in spite of himself. Funny, how things change when you think of them that way,” he said.

Change your thoughts and you change your world.

积极思考的力量

有一个男人曾打电话给诺曼?文森特?皮尔。他很沮丧并且告诉牧师他已经生无可恋。皮尔邀请这人来到他的办公室。“什么都没有了，毫无希望。”这个人对他说，“我生活在最深的黑暗中。实际上，我已经完全失去了生活的信心。”诺曼?文森特?皮尔同情的笑了笑。

“让我们一起来看看你的情况吧，”他平静的说。他在一张纸的中间划了一条垂直线。他建议他们在左边列出这人失去了的东西，在右边列出他拥有的。“你不需要右边的那栏，”那人悲伤的说，“我什么都不剩了。”

皮尔问道“你妻子是什么时候离开你的？”

“什么意思？我妻子没有离开我，我妻子爱我。”

“很好”，皮尔热诚的说，“那么这将是右手边栏目的第一项——妻子没有离开。那么，你的孩子什么时候进了监狱？”“真可笑，我的孩子没有进监狱。”

“好，那是右手边栏目的第二项——孩子没有进监狱。”皮尔说着，并草草记录下来。

在几个同样的问题之后，这个男人终于明白了其中的道理并不由自主地笑了，“真有意思，怎么当你用那种方式思考的时候事情就变样了。”他说。改变你的思维，你就改变了你的世界。

武汉实验外国语学校初中部物理光的折射透镜(提升篇)(Word版含解析)

一、初二物理光的折射透镜实验易错压轴题（难） 1．探究凸透镜成像的规律。 (1)选取焦距为10cm的凸透镜、蜡烛和光屏，将它们置于光具座上。点燃蜡烛，调整凸透镜和光屏的高度，使它们的中心与烛焰的中心大致在______； (2)当蜡烛、凸透镜在如图所示的位置时，调整光屏到______（填“A”、“B”或“C”）位置时，生活中的______（填“照相机”“投影仪”或“放大镜”）就是根据这个成像原理制成的； (3)保持凸透镜的位置不变，将蜡烛和光屏位置对调，光屏上______（填“能”或“不能”）再次看到清晰的像。若在此基础上将一个度数合适的远视眼镜放到蜡烛和凸透镜之间，还想在光屏上看到清晰的像，应将光屏适当______（填“靠近”或“远离”）凸透镜。【答案】同一高度C投影仪能靠近【解析】【分析】【详解】 (1)[1]为使烛焰的像成在光屏的中心，在做实验的过程中，调整凸透镜和光屏的高度，使烛焰、凸透镜和光屏三者中心大致在同一高度。 (2)[2]当蜡烛、凸透镜在如图所示的位置时，蜡烛在1倍焦距和2倍焦距之间，像会成在2倍焦距以外，所以光屏要调整光屏到C点。 [3]生活中的投影仪成像原理是物体在1倍焦距和2倍焦距之间，像在2倍焦距以外。(3)[4]保持凸透镜的位置不变，将蜡烛和光屏位置对调，根据光路的可逆性光屏上仍能成清晰的像。 [5]若在此基础上将一个度数合适的远视眼镜放到蜡烛和凸透镜之间，光线通过凸透镜后会会聚一些，还想在光屏上看到清晰的像，就要让光屏靠近凸透镜。 2．做“探究凸透镜成像规律”的实验。如图所示，一束平行光射向凸透镜，在光屏上得到一个最小、最亮的光斑，该凸透镜的焦距是____________cm。 (1)点燃的蜡烛、凸透镜、光屏三者在光具座上的位置如图之所示，则烛焰的像将成在光屏

武汉实验外国语学校初中部2020-2021年上册期末化学试题(含答案) 一、九年级化学上册选择题 1．某化学兴趣小组为了测定鸡蛋壳中碳酸钙的含量，取一定质量洗净、粉碎后的鸡蛋壳样品放于烧杯中，向烧杯中滴加稀盐酸(整个过程不考虑盐酸的挥发和气体的溶解)，实验测得烧杯中剩余物质的质量与加入盐酸的质量之间的关系如图所示。下列有关说法正确的是 A．所取的鸡蛋壳样品的质量为125g B．当滴入150g稀盐酸时，样品与稀盐酸恰好完全反应 C．反应完全后产生二氧化碳的质量为9.9g D．该鸡蛋壳样品中碳酸钙的质量分数为80% 2．在反应X + 2Y → M + 2N中，已知M和N的摩尔质量之比为，当1.6g X与Y完全反应后，生成4.4g M。则在此反应中Y和N的质量之比为 A ．B．C．D． 3．下列实验设计合理的是（） A．测定空气中氧气含量B．探究燃烧的条件 C．验证质量守恒定律D．氧气验满 4．下列问题的研究中，没有利用．．．．对比实验思想方法的是（）

A．研究空气中氧气含量B．比较金属活动性 C．研究燃烧的条件D．研究二氧化碳与水反应 5．运用推理、归纳、类比、对比的方法得出下列结论，其中合理的是( ) A．不同元素组成的物质是化合物，同种元素组成的物质是单质 B．水和过氧化氢的组成元素相同，则两者的化学性质相同 C．Na+、Mg2+、Cl-的最外层电子数均为8，由此得出离子的最外层电子数均为8 D．同温下分解氯酸钾,加催化剂的反应速率快，说明催化剂可以改变反应速率 6．实验是进行科学探究的重要手段，实验方案的设计是实验成功的基本保证。下列实验方法设计不合理的是（）选项实验目的实验方法 A检验一瓶气体是否为氧气将带火星的木条伸入瓶中 B鉴别空气和氧气将燃着的木炭放入集气瓶中 C鉴别食盐和白糖观察颜色进行区别 D验证浓度对反应的影响将燃着的木条分别伸入氧气和空气中 A．A B．B C．C D．D 7．有氧化镁和另一种金属氧化物组成的混合物共 4g，经测定其中含有氧元素 1.8g，则另一种金属氧化物是（） A．Al2O3B．CuO C．CaO D．Fe2O3 8．将25克甲物质跟5克乙物质发生反应，所得混合物中有10克甲，11克丙，还有另一种新物质丁，若甲、乙、丙、丁的相对分子质量分别为30、20、44、18，化学式分别为A、B、C、D。则下列化学方程式正确的是 A．2A + B ═ C + 2D B．A + 2B ═ 2C + D C．A + 2B ═ C + 2D D．2A + B ═ 2C + D
