Her frozen fingers touched the flame trying to feel alive. She could feel the warmth but it was a cold heat, as if the candle was rejecting her.

Her arms turned red because of the cold, her short sleeved shirt not giving her enough warmth. The winter air grabbed(抓住) at her arms, causing her pain, but she didn’t mind. She knew she should put her jacket on, it was winter in Connecticut, but that would be giving up. Up here, in this tree she felt safe.

She looked at the candle, surrounded by hardening wax(蜡). She placed her fingers gently on the warm green wax. This candle was a reminder of her life inside that house, a life she would have to return to eventually.

As a child, she had gotten this candle. She spent all she had on it. The beautiful crystal box (水晶盒)had caught her eye. Five whole nickels(五分币) had brought her that candle.

She gave it to her mother for Mother’s Day. Her mother had managed a smile and put it on a shelf. “It’s very pretty, honey! I will put it right here.” Since then that candle had never been moved, never been lighted, sitting dusty on a cluttered shelf that no one could see. Later on, her parents got divorced.

By now the candle was colder than the air and the darkness was complete. The snow on the ground made the night lighter and less satisfying than it had been before the first snowfall. She liked the darkness because she felt safe in it. From the glances of her friends who liked the girl she used to be. From the boys who could never figure out who she was. From her guidance counselor(顾问) whose endless worried looks never made her feel any better.

No one was outside at this time of night. She was alone in the world, just how she liked it. Just as she was about to lean back against the branch, she heard a sound.

She heard footsteps breaking the ice in the snow, heading toward her. He was making his way toward the white fence at the edge of the building, right against the road. Normally she would have ignored this person and stayed on her branch faraway from human contact, but this figure had something with him. He trudged(吃力地走) toward the white fence carrying a case. The figure reached the fence, opened the case and took out a shiny object.

She took her eyes off this figure only long enough to climb down the tree to get a better view of him. She reached the bottom and saw that the person had turned to face the street, sitting on the white fence that she and her friends once sat on. She stepped carefully on the ice, making her way toward him.

And then a beautiful sound of music came from the shiny object. She stopped and listened to it. She started walking towards the guy again. Just as she was about to step onto the snow banks, she slipped on the ice crashing to the ground. The figure turned around in surprise and a sudden recognition fell upon them both.

小题1:The girl was hiding in the tree at deep night to ______.

A.keep herself from the cold

B.wait for the boy to come

C.want to be left alone

D.seek safety from any hurt小题2:From the story, we can learn that ______.

A.the girl suffered a lot in her life

B.the girl’s parents divorced because of her

C.teachers and friends treated the girl badly

D.the girl used to stay in the tree when feeling sad小题3:The underlined word “it” in the story refers to ______.

A.leaning back against the branch

B.being alone in the world

C.not being disturbed at night

D.it being dark with snow around小题4:From the end of the story, it can be known that the girl _______.

A.knew the person

B.knew what the object was

C.realized her wishes

D.would never feel alone any more

答案

小题1:D

小题2:A

小题3:B

小题4:A

题目分析:文章讲的是一个女孩喜欢独处在深夜中,由于父母离婚等原因自己遭受了很多的苦难,在深夜中她喜欢这种孤独,喜欢藏在树上以寻求安全感。

小题1:细节题。根据文章Up here, in this tree she felt safe可知,这个女孩在深夜藏在树下是为了保护自己不受到伤害。故选D

小题2:细节题。从第一段及第二自然段可知,及后文讲到Later on, her parents got divorced.

她的父母亲也离婚了,所以可知这个女孩人生中经受了很多的苦难,故选A

小题3:推断题。从文章No one was outside at this time of night. She was alone in the world, 可知,在这个夜晚没有人在外面,她在这个世界是孤独的,但是她喜欢这种孤独,故选B

小题4:推断题。从The figure turned around in surprise and a sudden recognition fell upon them both.可知,这个惊讶的转身,很快他们俩都认出了对方,故选A

点评:本文理解较难,对于景物的描写非常多,通过景物来衬托出人物的孤独与落寞。句子生词较多同时短句及句子成分复杂也给文章增加了很大的难度,值得注意的是这类文章如果第一遍没有看懂可以通过做题在解题的过程中通过选项来反推题目的意思,这样有助于我们更好地解题。

计算题

镁、铝、铁及其化合物在生产和生活中有广泛的应用。

(1)镁铝合金用在飞机制造业,现有3.90克镁铝合金溶于足量的2mol/L稀硫酸中生成0.2mol氢气,计算并确定镁铝合金中物质的量n(Mg): n(Al)=        

(2)硫铁矿的主要成分为FeS2(假设杂质只含SiO2)是生产硫酸的原料。取某硫铁矿10g在足量的空气中煅烧(4FeS2+11O2→2Fe2O3+8SO2),充分反应后冷却,称得固体质量为7.4g(杂质SiO2不反应)。该硫铁矿中FeS2的质量分数为              

(3)现有一定量的铁粉和铝粉组成的混合物跟100 mL稀硝酸充分反应,反应过程中无任何气体放出,往反应后的澄清溶液中逐渐加入4.00 mol·L-1的NaOH溶液,加入NaOH溶液的体积与产生沉淀的质量的关系如图所示(必要时可加热,忽略气体在水中的溶解):纵坐标中A点的数值是               

(4)炼铁厂生产的生铁常用于炼钢。取某钢样粉末28.12g(假设只含Fe和C),在氧气流中充分反应,得到CO2气体224mL(标准状况下)。

①计算此钢样粉末中铁和碳的物质的量之比为                (最简单的整数比)。

②再取三份不同质量的上述钢样粉末分别加到100mL相同浓度的稀H2SO4中,充分反应后,测得的实验数据如下表所示:

实验序号
加入钢样粉末的质量(g)2.8125.6248.436
生成气体的体积(L)(标准状况)1.1202.2402.800
 

则该硫酸溶液的物质的量浓度为                  

③若在上述实验Ⅱ中继续加入m克钢样粉末,计算反应结束后剩余的固体质量为   g (保留3位小数)
