题文
If you are ever planning to buy a telescope and want to get yourself involved in astronomy it is always a good idea to know a bit of the sky.Get acquainted with a few constellations(星座) so that it will be easier for you to spot the constellations when you are using your telescope.It’s a good idea to buy a few magazines on astronomy to help you to get familiar with the constellations in the sky and also read a few reviews on the different types of telescopes in the market.This will help you gather all the information that is out there regarding telescopes and what people have to say about them.
It’s advisable to go in for a pair of binoculars(双筒望远镜) before you buy your first telescope so that you can get used to spotting constellations before your view of the sky is narrowed down.This will also help you know if you really want to get involved in astronomy.Many people buy a costly telescope and then discover that they’re not actually interested in astronomy.
Experience has no substitute,and there certainly is nothing better than using different telescopes before you buy one.This will help you to get the feel of all the types of telescopes and you will know which one is easier for you to use.A large aperture(光圈) refractor(折射) may give you an excellent image but you may not be able to keep a steady hand while using it resulting in a blurry image.
There are three types of telescopes that are available in the market.If you want a more elegant looking telescope you can always choose to buy a fine brass telescope.It’s good to become acquainted with each type before going for the plunge of a first telescope.The first type of telescope is the refractor telescope,which uses lenses to gather light to a focus at the eye piece.The use of lenses helps the telescope have a superior image.A refracting telescope is not as portable as the other two types of telescopes and so you will have to buy one with a small aperture.
The second type of telescope is the Reflector.Made by Sir Isaac Newton,this telescope functions by focusing the light back at the front of the tube,which is where the eyepiece sits,by using parabolic(抛物线的) mirrors and another smaller mirror to deflect the light.There is no added color in the image caused by refraction of light since this telescope does not use lenses.These are the cheapest of all telescopes and are more portable than refractors.

【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小,追根溯源,探索各项风俗的历史渊源,内容有趣。命题也以送分题为主,如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松,试题做起来比较顺手,但绝不能掉以轻心。因为稍不留神,就会丢分。
【备考提醒】
为了保证较高准确率,建议同学们做好以下几点:
1、保持正常的考试心态。笔者在教学中发现,越是容易的试题,同学们越是容易失分。为什么呢?因为在这种情况下,同学们极易产生麻痹思想,认为题目好做,就不引起高度重视,于是思维不发散、不周密。而命题人就是利用同学们的这一弱点,设计陷阱题。所以,无论试题难易与否,我们都要保持正常的考试心态。试题容易,不欣喜;试题难,不悲观。
2、根据前面讲到的方法,认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义,确定多义词或短语在文中的意思,确认文中的某个代词所指代的对象,或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子,切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提,以具体事实为依据进行推理,做出判断。这种推理方式比较直接,只要弄清事实,即可结合常识推断出合理的结论。
