Nanowires are thin wires about one-hundredth the width of a human hair, used as electronic parts, and also as solar cells.“On Mars, about 96% of the atmosphere is CO2.

25、 dog Khan would act with aggression (攻击性) towards her young 17-month-old baby, Charlotte!The day began with the usual playtime outside. Although baby Charlotte had her parents watching from a distance, they did not notice anything out of the ordinary. Charlotte and the new dog had been making a habi
26、t of playing like this. However, things were different that day. Catherine watched as Khan threw her baby across their backyard! Why was Khan acting as though a lovely child were a threat? Catherine watched him drag her child, hoping he would stop. Sadly, it seemed Catherine needed to immediately in
27、tervene because this was only the beginning. He tightly clenched his jaws into her diaper (纸尿片) to throw her back and forth. Things got out of hand. Certainly, Catherine was angry with Khan for throwing her girl. However, something deep down told Catherine there was more to this than what they were
28、seeing. Little did she know, these doubts would turn out to be true.But her baby was still in great danger. Catherine noted that her baby seemed a target. That moment we mentioned when the dog sunk his teeth into Charlottes diaper and used his strength to throw her baby like “a doll”. How terrifying
29、! Luckily, those teeth did not go near her skin and especially the face and the baby was actually quite calm. Perhaps, the baby understood something about Khans intentions.Catherine knew that she needed to act fast and catch her poor child. Something happening to Khan next confused the whole family.
30、While the baby stayed calm, others could not help but panic. Catherine said, “Had I not seen it with my very own eyes, Id never have believed it.” Therefore, she ran to Charlotte and carried her to safety.注意:续写词数应为150左右。Paragraph 1:While Catherine brought her baby to shelter, Khan barked madly and t

32、类。technologies是名词,应用形容词修饰。故填Advanced。2.terrifying考查形容词。句意:尽管那个手术令人害怕,但它对我的健康有好处。此处应用形容词作表语,且手术是“令人害怕的”,应用v.-ing形式的形容词。故填terrifying。易错分析本题易错填为terrified,主要是因为分不清v.-ing形式的形容词和v.-ed形式的形容词的意义。v.-ing形式的形容词表示“令人的”,而v.-ed形式的形容词表示“感到的”。3.Exposure考查名词。句意:众所周知,接触铅会损害儿童的大脑。设空处作句子的主语,因此该空应该填名词。4.dusty考查形容词。句意:他的
33、黑色的帽子成了土褐色,衣服也又脏又破。根据句子结构可知,此处应用形容词和torn并列作表语。故填dusty。.1.Taking off his coat2.can we wipe out3.does have an effect on4.before the police arrive.1.to see考查非谓语动词。句意:一种选择就是探索其他星球看看我们是否能在它们上面居住。在该句中应该用动词不定式表示目的。2.which考查非限制性定语从句。句意:最有可能的选择是火星,它离地球比较近,环境也没有其他行星那么恶劣。设空处引导非限制性定语从句,且关系词在定语从句中作主语,指代的先行词Mars为
34、世界上独一无二的事物,因此用关系代词which引导该从句。注意不能用that引导非限制性定语从句。3.that考查代词。that在此处指代前面的名词environment。4.sending考查非谓语动词。句意:我们的航天探测器已经沿该行星轨道运行,发回了宝贵的数据和令人震惊的图像。send与句子的主语Our probes构成主动关系,所以用现在分词作伴随状语。故填sending。5.intelligence考查词性转换。句意:然而,送人去那里需要人类所有的技能、勇气和智慧。此处and连接并列的名词作并列宾语。intelligent的名词形式是intelligence。6.have succe
35、eded考查动词的时态。此处表示科学家最近已经在一种类似火星的环境里成功地种植了各种植物。根据前面的时间状语More recently并结合句意可以判定时态为现在完成时。7.plants考查名词复数。a variety of意为“各种各样的”,由此可以判断此处用名词的复数形式。8.definitely考查副词。此处表示那肯定是向前迈进的一大步,应用副词作状语。故填definitely。9.on考查固定搭配。句意:这种变化正在对生物圈产生可怕的影响。have an effect on意为“对有影响”。10.better考查形容词的比较级。根据设空处前面的much并结合句意可以判断此处应该用比较级
36、形式。能力提升练.这是一篇说明文。文章主要介绍了可以在火星上自己生产有机化合物的新系统。文章分析了它运转的可能性以及它的优点。1.C推理判断题。根据文章第一段可知,人类若想在火星上生活,移民者需要生产一系列的有机化合物,从燃料到药物,它们从地球上运送过去会很昂贵。根据第三段可知,研究人员在研究一种新的系统,该系统可以捕捉阳光的能量,将二氧化碳(CO2)和水转化为有机物质的构成要素。综合分析,新生物系统的功能是帮助在火星上生产有机化合物。A项“减少火星上的空气污染”、B项“把许多有机物带到火星”和D项“不用阳光就能制造出有机物质的构成要素”都不是新生物系统的作用。故选C项。2.A细节理解题。根据
37、文章第四段内容和第五段“The only other requirement, besides sunlight, is water, which on Mars is relatively more than enough in the polar ice caps and likely lies frozen underground over most of the planet,” said Yang.可知,火星上存在着大量的二氧化碳,水和阳光让其自己生产有机物质成为可能。B项“火星比其他星球更容易登陆”和C项“太空技术已经有了很大发展”不是让火星自己生产有机物质成为可能的原因;D项“在
38、火星上发现了大量氧气”不符合文章内容。故选A项。3.C细节理解题。根据文章最后一段中的Plants, however, have a quite low.which is 4%5% efficient.(然而,植物的效率相当低,通常将不到0.5%的太阳能转化为碳化合物。杨的系统可与将二氧化碳转化为糖类效果最好的植物相媲美,其效率为4%5%。)可知,杨的系统的效率比自然光合作用要高。A项“它不需要二氧化碳和水”、B项“它可以被太空植物代替”和D项“它基于不同于光合作用的规律起作用”均不符合文章内容。故选C项。4.B推理判断题。本篇文章主要介绍了可以在火星上自己生产有机化合物的新系统。文章分析了它
39、运转的可能性以及它的优点。故本文应取材于报纸的“科学”部分。A项“生活”、C项“健康”和D项“教育”都不包括这样专业的科技内容。故选B项。.本文是一篇说明文。文中列举了保护自己免受病毒侵袭的方法。1.G该空的作用是承上启下,根据下文列举的预防方法可知,G项符合逻辑,是一个过渡句。2.F根据设空处后面的结构和意思可以判断,此空应该是一个从句,根据设空处后面的意思并结合该句所在的部分(这部分与口罩有关)可以看出答案为F项。3.C由该空所在的位置可以判断,此处应该是一个主题句,且其后项目都是有关洗手的,所以答案是C。4.E结合该空所在的段落可以看出,其与公共场合如医院、火车站和飞机场等有关,在这些公
40、共场合应该戴口罩,因此答案为E。5.B由文章的结构判断,此处应该是祈使句,并与家禽、家畜等有关,因此答案为B。.One possible version:Paragraph 1:While Catherine brought her baby to shelter, Khan barked madly and then fell down. He did not just fall down for nothing as he began crying. No one understood what was going on! The dog continued crying and then
41、 fell almost lifelessly. Now this sent Catherine into panic mode. She focused on the dog, watching his dying eyes and realized it was clear that he needed emergency care. And it occurred to her that Khan had been protecting her child instead of attacking her.Paragraph 2:Finally, the whole family rea
42、lized Khan was a hero of attacking a poisonous snake. It turned out that Khan was protecting Charlotte from a poisonous, deadly snake even though living with the family for only four days. Thus, it was lucky that Khan caught the snake and did really save that babys life, showing his unconditional love. With the rest of the family watching in shock, Catherine hurried to the vets. Fortunately, Khan, this heroic animal, impressed even the vets with his rapid recovery and progress. Finally, the family could be reunited!
