【题目】如图是一组检验氯气性质的装置。

(1)现关闭活塞K,若有色布条是干燥的,溶液B为浓硫酸,则有色布条________;若溶液B为水,则有色布条________;若溶液B为饱和的NaHCO3溶液,则有色布条________。

(2)现打开K,溶液B为氢氧化钠溶液,通入的Cl2是湿润的,布条是干燥的,则有色布条________。

【答案】(1)不褪色 褪色 不褪色

(2)褪色

【解析】(1)关闭K通入Cl2,若B为浓硫酸,则进入()的是干燥的Cl2,有色布条不褪色;若B为水,则进入()的是湿润的Cl2,有色布条褪色;若B是NaHCO3溶液,则Cl2在()中被消耗,有色布条不褪色。

(2)打开K,尽管B是NaOH溶液,湿润的Cl2还是直接进入(),有色布条褪色。

【题目】阅读理解

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

A

Most people usually traveled by ship and train which are driven by steam engine. It played an important part in many kinds of vehicles several scores of years ago. Who invented steam engine and what units could be used to measure the power of engine?

The word "horse-power" was first used two hundred years ago. James Watt from a worker’s family made the world first widely used steam engine. At first, he couldn’t tell people how powerful it was, because there were no units at that time. Watt decided to find out how much work one strong horse could do in one minute. He named that unit one horse-power. In this way he could measure the work of his steam engine.

He discovered that a horse could lift a 3,300-pound weight 10 feet into the air in one minute. His engine could lift a 3300-pound weight 100 feet in one minute. Because his engine did ten times as much work as the horse, Watt called it a ten horse-power engine.

【1】 The main idea of the passage is ___________.

A. how much power does a horse have

B. James Watt invented the steam engine

C. why Watt’s engine is called a ten horse-power engine

D. James Watt first used horse-power as a unit of measure

【2】The story says that Watt made the first ___________.

A. widely used steam engine

B. horse-power engine

C. useful engine

D. engine

【3】 James Watt was born in ___________.

A. a farmer’s family

B. a worker’s family

C. a teacher’s family

D. a doctor’s steam engine

【4】One horse-power means the _____________.

A. weight a horse could do in ten minutes

B. work a horse could do in ten minutes

C. work a horse could do in a minute

D. weight of one horse

My little cousin is greatly interested on science. And he does some dangerous experiments sometime. Although his parents want to encourage him to be great scientist, at times they worry about his safety. Last week, when my cousin was doing an experiment, he hurts his thumb. My aunt felt sadly and wanted him to stop from doing that experiment. However, my cousin didnt want to give up. She said, "Many scientists got hurt when they were doing experiments, so they didnt give up." My aunt had to let him finish the experiments and he finally succeeded in finish it.
