雅思托福考试对于想要出国留学或移民的人来说,是一个非常重要的考试。因此,了解考试的时间表和出分时间对于准备考试的考生来说非常关键。下面中国教育在线外语频道小编就为大家分享一下“托福阅读如何做修辞目的题呢?技巧一:牢记作者目的经典位置”?
我们知道常见的段落结构有总分、分总和总分总,而在托福阅读中先总后分的结构比较受偏爱。
所以通常情况下作者目的往往出现在所提及信息的前面,可能是比较直接的前一句,也可能是整段的中心句,放在段首部分,需要具体情况具体分析,我们可以结合下面的例子来理解。
例题一:
Magnification, the increase in the apparent size of an object, is one important factor in microscopy. Also important is resolving power, a measure of the clarity of an image. Resolving power is the ability of an optical instrument to show two objects as separate. For example, what looks to the unaided eye like a single star in the sky may be resolved as two stars with the help of a telescope. Any optical device is limited by its resolving power. The light microscope cannot resolve detail finer than 0.2 micrometers, about the size of the smallest bacterium; consequently, no matter how many times its image of such a bacterium is magnified, the light microscope cannot show the details of the cells internal structure.
2.Why does the author mention a telescope as part of the discussion of microscopes?
A. To show how microscopes and telescopes are different.
B. To emphasize the importance of magnification in all optical devices.
C. To explain how the development of the microscope depended on the invention of the telescope.
D. To illustrate the concept of resolving power.
这道题就属于作者目的在定位句前一句或者说前两句的情况。我们可以看到,包含a telescope的定位句以for example开头,明显是一个例子。
通常情况下,例子要论证的对象会放在例子的前面。不管是例子里面还是例子前面两句,都出现了resolve这个词,说明它们在论述一个point,是一个意群。
而段落的开头句讲到的是magnification,则是一个和例子无关的东西。所以,作者举出telescope的例子是为了让我们更容易理解resolving power这个概念。
