A

People in Los Angeles are known for their love of cars. The city is very large, and its public transportation is slow. So people drive everywhere. But now, a group of bicyclists are trying to get people out of their cars and on bikes.

Devon Fitzgerald say s he has to be careful when he rides his bike in the streets. ―A lot of people are in a rush, and it's very difficult to keep careful, for they would rather care for their speed than your safety.‖ Although riding a bike to work can be dangerous, he prefers it to a car. ―It's much simpler than driving a car. For example, I don't have to worry about parking.‖

Roger Rosas drives to work. "You always have to make sure you look to the other side because someone would rush across by bike. Or you can easily get into an accident. "

To make bicycling safer, some people who live and work near each other are riding to work together, which they call a "bike train". Nona Varnado helped create the group L. A. Bike Trains. "You're in a big group. If you're afraid of riding alone, you can now ride with experienced riders. " Nona said that people would feel safer by riding together in a group.

B

I still remembered my first day of second grade. I was led to a room. No teacher yet. Girls talking. Boys trying to kill each other.

I took some paper and a pencil, picked a desk, and went to work. Minutes later, a girl came over and sat on top of my desk.

―What're you doing?‖ she said.

―Writing to 100,‖ I replied.

―Is that you can do?‖

―No,‖ I said.

Then I rose from my seat to get my pencil sharpener. I had no idea that when I stood, the desk would fall over and hurt her leg.

Her name was Jane. From that day on--she was my best friend. Wherever we went--to school or church or basketball games, Jane saved me a seat or I saved one for her.

Many years later, after college, I moved to California and married. Jane stayed in our hometown to be a social worker. We were friends for more than 50 years. After her death seven years ago, I still think of her often, especially at the start of the school year.

TV ads try to tell us what children need for school—new shoes, clothes, backpacks. But really, children's needs are simple. Besides the basics—to be fed, cared for, and loved—they need the gift of friendship.

For years, I feared how people saw me. But one day, I finally understood. I didn't need to be smart or pretty or popular. I just needed to be kind.

My grandson Henry recently finished his preschool and received a prize for ―Friendship‖. Even an Olympic medal wouldn't make me prouder! I think children need to know that they are loved. They need to know that they have all they need and the best way to win friends is to be one.

5. When she came into the classroom, the writer ________.

A. went to talk with Jane quickly

B. helped Jane write the numbers to 100

C. worked quietly at her desk alone

D. was afraid that others would fight with her

6. From the passage we know that__________.

A. the writer's leg was hurt on the first day of school

B. the two girls were close friends until Jane died

C. Jane often helped the writer to do some social work

D. the two girls stayed in the same city after college

7. Henry received a prize for "Friendship" probably because _________.

A. he was kind to others

B. he was smart at his schoolwork

C. he was loved by his grandma

D. he joined in the Olympics

8.The best title of this article would be__________.

A. My Best Friend Jane

B. How to Choose Friends

C. My First Day at School

D. Friendship Values

C

The winter of 1948 was very difficult for our family of eight living in Knoxvile, Tennessee. Unfortunately, Dad became ill and soon was out of a job. I was only 8 years old and my younger brother, Buddy was 7. After school we went to pick coal(煤) that fell from the coal train along the railroad near our home. When the train slowed down, we ran alongside it. After the train passed, we picked up the fallen coal.

One day, the train stopped for a short time unusually. My brother and I were digging around in the snow when the train's fireman came to the window and shouted to us, ―Why are you boys digging in the snow? Are you looking for gold?‖ he laughed.

―No, sir,‖ I replied, ―We are finding coal.‖

―Why doesn't your daddy buy coal? It's really dangerous here.‖

―Our daddy is very sick and we have no money to buy food and coal,‖ I answered.

The fire man turned and went inside. After a moment, he shouted again. ―Hey! Bring that coal bucket(桶子) here. I got something for you.‖ Then the fireman filled our bucket with clean coal. We were happy with his gift, and we knew we could go home early that day.

He smiled the kindest and warmest smile I had ever seen. ―You two boys come here the day after tomorrow and I'll throw off some coal.‖

2018年中考化学真题分类汇编创新题(有答案解析)

专题分类:创新题 1.(2018吉林)请完成下列思维导图。 【答案】(1)< (1分);(2)纯净物(1分);(3)C(1分);(4)P2O5(1分) 【解析】(1)白醋是酸,pH<7;(2)物质分为混合物和纯净物;(3)金刚石含有C元素;(4)五氧化二磷的化学式为P2O5。 2.(2018安徽)归纳法是学习化学的重要方法之一,下列图示正确的是为() 【答案】A 【解析】化学反应的四种基本类型:化合反应、分解反应、置换反应和复分解反应;物质的分类:纯净物和混合物,纯净物包括单质和化合物;地壳中元素含量:氧>硅>铝>铁;金属的化学性质:活泼金属与酸反应生成盐和氢气,金属与氧气反应生成金属氧化物,不能生成盐。故选A。 3.(2018重庆B)小明笔记中有处错误你认为是图中的哪一处() A.a处 B.b处 C.e处 D.d处 【答案】B 【解析】赤铁矿的主要成分是氧化铁(Fe2O3);用一氧化碳在高温下与氧化铁,利用了一氧化碳还原性把铁从氧化铁中还原出来,一氧化碳发生了氧化反应,氧化铁发生了还原反应;该反应不属于置换反应。故选B。 4.(2018南京)如图为三种不同浓度的氢氧化钠溶液与对应浓度的盐酸反应的曲线。

下列说法正确的是() A.在a、b、c三种曲线所示的实验中,所用盐酸浓度越大,V时所得溶液的pH越大 B.在a曲线所示的实验中,若用酚酞做指示剂,酚酞溶液由红色变为无色 C.在a、b、c三种曲线所示的实验中,反应速率相同 D.在a、b、c三种曲线所示的实验中,溶液酸性由强到弱的顺序是a>b>c 解析:A、由图可以看出是向盐酸中加入氢氧化钠溶液,在a、b、c三种曲线所示的实验中,恰好完全反应,即pH=7时,需要氢氧化钠溶液体积相等,因此所用盐酸浓度越大,需要加入的氢氧化钠溶液浓度也越大,V 时氢氧化钠溶液过量,所得溶液的pH越大,该选项说法正确; B、是向盐酸中加入氢氧化钠溶液,在a曲线所示的实验中,若用酚酞做指示剂,酚酞溶液由无色变为红色,该选项说法不正确; C、在a、b、c三种曲线所示的实验中,由于反应物浓度不同,反应速率不相同,该选项说法不正确; D、在a、b、c三种曲线所示的实验中,随着加入氢氧化钠溶液的多少,溶液分别显酸性、显中性、显碱性,该选项说法不正确。 故选:A。 5.(2018成都)如图物质经一步反应转化的两种途径,相关说法正确的是() A.氧化物为SO2B.X只能是硫酸 C.②可能有沉淀生成 D.①②属于复分解反应 解析:A、二氧化硫与氢氧化钠溶液反应生成亚硫酸钠和水,氧化物应为三氧化硫,故选项说法错误。 B、氢氧化钠与三氧化硫反应生成硫酸钠和水,X不一定只能是硫酸,故选项说法错误。 C、氢氧化钠与硫酸铜溶液反应生成氢氧化铜沉淀和硫酸,②可能有沉淀生成,故选项说法正确。 D、非金属氧化物与碱的反应,不属于复分解反应,故选项说法错误。 故选:C。 6.(2018重庆B)某课外活动中,学生利用下图所示的材料完成探究实验,杠杆已调至平衡。
