部编版八年级语文上册第二单元课外语段阅读题（附答案）（一）小提琴的力量（21分）①那天中午，我驾车回到花园别墅。
刚刚进客厅门，我就听见楼上的卧室里有轻微的响声，那种响声我太熟悉了，是那把阿马提小提琴发出的声音。
“有小偷！”我一个箭步冲上楼，果然不出我所料，一个大约12岁的少年正在那里抚摸我的小提琴。
那个少年头发蓬乱，脸庞瘦削，不合身的外套鼓鼓囊囊，里面好像塞了某些东西。
我一眼瞥见自己放在床头的一双新皮鞋失踪了，看来他是个小偷无疑。
我用结实的身躯堵住了少年逃跑的路，这时，我看见他的眼里充满了惶恐和绝望。
就那刹那间我突然想起了记忆中那块青色的墓碑，我愤怒的表情顿时被微笑所代替，我问道：“你是拉姆先生的外甥鲁本吗？我是他的管家，前两天我听拉姆先生说他有一个住在乡下的外甥要来，一定你了，你和他长得真像啊！”②听见我的话，少年先是一愣，但很快就接腔说：“我舅舅出门了吗？我想我还是先出去转转，待会儿再来看他吧。
”我点点头，然后问那位正准备将小提琴放下的少年：“你很喜欢拉小提琴吗？”“是的，但我很穷，买不起。
”少年回答。
“那我将这把小提琴送给你吧。
”我语气平缓地说。
少年似乎不相信小提琴是一位管家的，他疑惑地看了我一眼，但还是拿起了小提琴。
临出客厅时，他突然看见墙上挂着一张我在悉尼大剧院演出的巨幅彩照，于是浑身不由自主地颤栗了一下，然后头也不回地跑远了。
我确信那位少年已明白是怎么回事，因为没有哪位主人会用管家的照片来装饰客厅。
③妻子回来后，我把将中午的遭遇告诉了她，然后问道：“你愿意再听我讲述一个故事吗？”妻子迷惑不解地点了点头。
“当我还是一个少年的时候，我整天和一帮坏小子混在一起。
有天下午，我从一棵大树上翻身爬进一幢公寓的某户人家，因为我亲眼看见这户人家的主人驾车出去了，这对我来说，正是偷盗的好时机。
然而，当我潜入卧室时，我突然发现有一个和我年纪相当的女孩半躺在床上，我一下子怔在那里。
那位女孩看见我，起先非常惊恐，但她很快就镇定下来，她微笑着问我：你是找五楼的劳德先生吗？我一时不知说什么好，只好机械地点头。

统编版八年级语文上册第二单元课内、课外阅读训练(含答案)
八年级语文期中复习：第二单元课内、课外阅读训练一、课内精读（一）阅读《藤野先生》中的两个选段，完成下面的问题。
【甲】“你改悔罢！”这是《新约》上的句子罢，但经托尔斯泰新近引用过的。
其时正值日俄战争，托老先生便写了一封给俄国和日本的皇帝的信，开首便是这一句。
日本报纸上很斥责他的不逊，爱国青年也愤然，然而暗地里却早受了他的影响了。
其次的话，大略是说上年解剖学试验的题目，是藤野先生在讲义上做了记号，我预先知道的，所以能有这样的成绩。
末尾是匿名。
我这才回忆到前几天的一件事。
因为要开同级会，干事便在黑板上写广告，末一句是“请全数到会勿漏为要”，而且在“漏”字旁边加了一个圈。
我当时虽然觉得圈得可笑，但是毫不介意，这回才悟出那字也在讥刺我了，犹言我得了教员漏泄出来的题目。
我便将这事告知了藤野先生；有几个和我熟识的同学也很不平，一同去诘责干事托辞检查的无礼，并且要求他们将检查的结果，发表出来。
终于这流言消灭了，干事却又竭力运动，要收回那一封匿名信去。
结束是我便将这托尔斯泰式的信退还了他们。
【乙】中国是弱国，所以中国人当然是低能儿，分数在六十分以上，便不是自己的能力了：也无怪他们疑惑。
但我接着便有参观枪毙中国人的命运了。
第二年添教霉菌学，细菌的形状是全用电影来显示的，一段落已完而还没有到下课的时候，便影几片时事的片子，自然都是日本战胜俄国的情形。
但偏有中国人夹在里边：给俄国人做侦探，被日本军捕获，要枪毙了，围着看的也是一群中国人；在讲堂里的还有一个我。
“万岁！”他们都拍掌欢呼起来。
这种欢呼，是每看一片都有的，但在我，这一声却特别听得刺耳。
此后回到中国来，我看见那些闲看枪毙犯人的人们，他们也何尝不酒醉似的喝采，﹣﹣呜呼，无法可想！但在那时那地，我的意见却变化了。
1.分别概括甲乙两文的内容。
______________________________________________________________________________________2.“日本报纸上很斥责他的不逊，……受了他的影响了。

新人教版英语选修八第二单元Reading的课文译文克隆：它将把我们引向何方？克隆一直与我们同在，而如今它还要持续下去。
这是一种用来生产与原型完全相同的动植物的方法。
当园艺师从生长着的植物上剪下枝条来培植新植物时，或者当你从植物上取下一小部分放在实验室里生长时，就会产生这种现象。
这种现象也发生在动物身上，从同一个原生卵子产生性别和相貌相同的双胞胎也是克隆。
实际上，它们是自然克隆现象。
克隆技术有两大用途。
第一，园艺师一直用它生产大量的供商用的植物；第二，它在对新植物物种的研究以及在对动物的医学研究方面都是很有价值的。
克隆植物简单，但克隆动物就比较复杂了，在程序上也就难以处理了。
起初，这种程序不够精确，所以克隆哺乳动物的多次尝试都失败了。
但是，科学家的决心和耐心最终得到了回报，这就是1996年具有突破性的克隆羊“多莉”的诞生。
它的程序如下图（略）所示：1.母羊（甲）提供一个卵细胞。
2.在卵细胞中取出细胞核。
3.卵细胞准备接受新的细胞核。
4.母羊（乙）提供一个供克隆的躯干细胞，该细胞应包含有生产一头新羊所需要的全部基因。
5.取出该细胞的细胞核。
6.用电把母羊（乙）的躯干细胞核和母羊（甲）的卵细胞连接起来。
7.细胞分裂并生长成胚胎。
8.把胚胎置入另外一头寄生的母羊（丙）体内。
9.这头小羔羊就是母羊（乙）所提供的细胞核克隆而成的。
整个科学界都在关注着首例成功的克隆动物多莉羊的成长。
多莉看来是在正常地成长着，这很令人鼓舞。
接着传来了多莉病重的坏消息。
研究克隆的科学家发现多莉得的病更容易发生在年老的羊身上，这让他们很沮丧。
可悲的是，同样无法控制的命运也在影响着其它物种，如克隆鼠。
科学家们脑海里产生的问题是“这是不是所有克隆动物的一个主要困难呢？”多莉只存活了六年，这是它的原型羊寿命的一半，然而多莉在死之前却又成功地以自然方式生产了一头小羔羊。
另一方面，多莉的出生引起了一阵强烈的反对，对媒体和公众的想象力也产生了巨大的影响。

There's only one place, and that's Hollywood, in California. Those you see from the tourist train are film sets(布景)in the Universal Studios, one of the oldest and largest film companies in the USA.A visit to Universal Studios brings back memories of great days of Hollywood, the films and the stars. But they are only memories. Hollywood isn't quite the same as it used to be. Costs have gone up and film-makers are afraid to spend their money on expensive new ideas. Instead, they repeat old ones.The film industry(产业)is changing fast. Teenagers still go out to the cinema. The cinema is a good place to meet friends away from home. But older people mostly stay at home to watch TV plays which have become as important as expensive films. These "soap operas(肥皂剧) " show rich families living in beautiful homes and wearing beautiful clothes, but They cost little and the actors and actresses are nearly all middle-aged, like many of the people who watch them.However, more and more films are made outside Hollywood now. New York is the most important new center, but there are many others as well. Film-makers have realized that they don'tneed Hollywood any more. Modern cameras and real houses instead of expensively made copies in a studio. Other states(洲)，especially Florida and Texas, are working hard to take the film business away from California. They are offering better working environment and,lower cost.But Hollywood is fighting back. The state of California is trying hard to keep its best-known industry.6. From the passage, we know Universal Studios is .A. a very large townB. a busy London streetC. a famous film companyD. an old Hollywood film7. What can we learn about "soap operas" from the passage?A.

Sports days, or sports meetings, are usually held in the warmer seasons, either at the beginning or the end of the school year. They are also called field days.Primary school sports days are fun．They usually have activities such as the egg and the spoon race and the sack race. Other events include the skipping race(跳绳)and the three—legged race. In middle and high schools，sports days include many of the common track and field events. They are more serious and competitive than primary school ones．Students’ parents and other relatives also come to the school on sports days．They watch children play. Many schools in the West have ’mothers and fathers’ races for parents to take part in!In the US，sports days have become too competitive to be good for students．Some parents put too much pressure on the children. Some schools don’t have ‘mothers and fathers’ races any more as there is much fighting and cheating1.What do children try to do when they take part in sports meetings?_____________________________________________________________2.What does the writer think about sports days?_____________________________________________________________3.Do you think sports days are good for students?
