1、12月8日雅思阅读考题回忆来源：朗阁培训中心编辑：xm发布日期:-12-14摘要：厦门朗阁培训中心为烤鸭们整顿了12月1日雅思听力考题回忆以及备考建议。考试日期：12月8日Reading Passage 1Title:对于鸟类发展的研究Question types:Table Completion; True/False/Not Given文章内容回忆用一种正例和一种反例讲达尔文的进化论。最后结论归到要保护环境也要保护动物进化的历程不被人打扰。开头先讲了达尔文在一种岛上观测一种鸟被选择的过程。然后是两个科学家在自己生活的地方也观测到同样的状况，三种鸟，不同的喙可以咬开不同大小的seed, 分别

2、是一场干旱一场大雨和另一场干旱影响了土地上种子的大小，进而影响三种鸟的数量。然后两位科学家就在一种岛上观测到动物的进化被人类影响的状况。在这个岛中部，没有人的影响，鸟类自由繁衍，别的地方由于有人的影响，本应当灭绝的鸟活得较好。英文原文阅读The major structural characteristic of avian, reptilian, and mammalian gastrulation is the primitive streak. This streak is first visible as a thickening of the epiblast at the post

3、erior region of the embryo, just anterior to Kollers sickle. This thickening is caused by the ingression of endodermal precursors from the epiblast into the blastocoel and by the migration of cells from the lateral region of the posterior epiblast toward the center. As these cells enter the primitiv

4、e streak, the streak elongates toward the future head region. At the same time, the secondary hypoblast cells continue to migrate anteriorly from the posterior margin of the blastoderm. The elongation of the primitive streak appears to be coextensive with the anterior migration of these secondary hy

5、poblast cells. The streak eventually extends 60-75% of the length of the area pellucida.The primitive streak defines the axes of the embryo. It extends from posterior to anterior; migrating cells enter through its dorsal side and move to its ventral side; and it separates the left portion of the emb

6、ryo from the right. Those elements close to the streak will be the medial (central) structures, while those farther from it will be the distal (lateral) structures.As cells converge to form the primitive streak, a depression forms within the streak. This depression is called the primitive groove, an

7、d it serves as an opening through which migrating cells pass into the blastocoel. Thus, the primitive groove is analogous to the amphibian blastopore. At the anterior end of the primitive streak is a regional thickening of cells called the primitive knot orHensens node. The center of this node conta

8、ins a funnel-shaped depression (sometimes called the primitive pit) through which cells can pass into the blastocoel. Hensens node is the functional equivalent of the dorsal lip of the amphibian blastopore (i.e., the organizer) and the fish embryonic shield.As soon as the primitive streak has formed

9、, epiblast cells begin to migrate through it and into the blastocoel). The primitive streak has a continually changing cell population. Cells migrating through Hensens node pass down into the blastocoel and migrate anteriorly, forming foregut, head mesoderm, and notochord; cells passing through the

10、lateral portions of the primitive streak give rise to the majority of endodermal and mesodermal tissues. Unlike the Xenopus mesoderm, which migrates as sheets of cells into the blastocoel, cells entering the inside of the avian embryo ingress as individuals after undergoing an epithelial-to-mesenchy

11、mal transformation. At Hensens node and throughout the primitive streak, the breakdown of the basal lamina and the release of these cells into the embryo is thought to be accomplished by scatter factor, a 190-kDa protein secreted by the cells as they enter the strea. Scatter factor can convert epith

12、elial sheets into mesenchymal cells in several ways, and it is probably involved both in downregulating E-cadherin expression and in preventing E-cadherin from functioning题型难度分析比较简朴的填表题和是非无判断题的组合。本篇文章从话题到题型组合都较为简朴。题型技巧分析是非无判断题是雅思阅读的典型题型，是复习备考时应关注的题型。一方面应当注意看清是TRUE还是YES, 本篇是TRUE/ FALSE/ NOT GIVEN。解题环

13、节：1. 速读问题的句子，找出考点词（容易有问题的部分）。考点词：比较级，最高档，数据（时间），限度副词，特殊形容词，绝对化的词（only, most, each, any, every, the same as等）2. 排除考点词，在余下的词中找定位词，去原文定位。3. 重点考察考点词与否有提及，与否对的。TRUE的原则是同义替代，至少有一组近义词。FALSE是题目和原文截然相反，不可共存，一般有至少一组反义词。NOT GIVEN原文未提及，不做任何推断，特别多考察题目的主语等名词在原文与否有提及。剑桥雅思推荐原文练习剑4 Test 1 Passage 2Reading Passage 2T

14、itle:新西兰一种多种族区域的演变历程Question types:List of Heading; 人名观点Matching; 填空文章内容回忆在新西兰的一种地方，有了新的建筑，为了融合各民族人民而建的，还为了融合建立了新的community, 并且组织人们喝茶什么的。题型难度分析两种配对题的组合，耗时比较久，难度较高。题型技巧分析Heading题型做题环节：1. 读题目规定，注意是将heading前的序号写在答题卡上2. 划去Example项，在Lists of headings中将例子的标题划去，同步将相应段落在文章中划去，以免做题时反复找3. 在给出的标题中划出核心词，以名词为主4.

15、 读文章段落，重要读段首和段尾，找出主题句5. 将段落主题句和标题相比较，选出答案注意事项：1. 在找主题句的时候，段首不一定是段落的第一句，诸多时候特别是第二段及后来的段落，第一句往往是对上一段的概况，第二句第三句才是主题句2. 如果本段有however, but等转折词汇以及also, although等，主题句即作者的中心在其背面3. 如果某段中反复浮现标题中的某个核心词，也可以鉴定此段的标题即是具有这个核心词的标题剑桥雅思推荐原文练习剑4 Test 2 Passage 1&3Reading Passage 3Title:What Can Company Do to SurviveQue

16、stion types:True/ False/ Not Given; 段落细节Matching文章内容回忆有关一种公司怎么在商界生存的。题型难度分析考生普遍反映词汇量规定不是很高，但是题目非常险恶。段落细节题和是非无判断题的组合，难度不是最高，但是需要通读文章。题型技巧分析段落细节配对难度较大，做时注意切不可逐题去原文整篇文章搜寻答案，这样会导致文章来来回回看诸多遍，耗时太长。1. 划出所有题目的keywords, 同步考虑到有也许浮现近义替代的词，有针对性的去原文寻找答案。例如：看到be conscious of立即想到雅思高频近义替代是be aware of, 看到reproduce想到

17、copy。2. 某些题目可以对题目进行细致的分析。平时通过精读多多熟悉文章构造安排，理解行文模式。3. 做题时以文章为基准，每看一段，浏览题目中的keywords与否与其有关。剑桥雅思推荐原文练习剑5 Test 3 Passage 1考试趋势分析和备考指引：Summary总体有所下降，T/F/NG优势仍然明显；虽然Summary总体有所下降，但是完毕句子题的浮现事实上跟它是一种完全契合的点，因此Summary题的中流砥柱的地位是不会变的。判断题无论浮现多少，都是我们该拿分的项，因此一定要注重它。Matching三种类型分派均衡，考察综合能力；Matching题已经不再着重于人物理论题或者信息配对题了，而是三种题型并驾齐驱，因此在复习Matching题时，一定要有的放矢，三种题型一定要均衡考量，不能忽视综合能力。小题型如简答题、流程图和表格题保持着一种轮换考试的趋势。因此在复习大题型的时候，一定要注意某些小题型的解题特点。
