托福阅读最后一道主旨题怎么做?托福阅读最后一道大题是六选三,即从六个选项中选取三个,加上给出的句子,合成对全文的概括。正确选项的特征是"the most important ideas in the passage",是文章的核心信息;错误选项的典型特征是文章细节。
托福文章题目:MINERALS AND PLANTS
下面分别是没段段首的信息:
Paragraph 1 Research has shown that certain minerals are required by plants for normal growth and development.
Paragraph 2 Mineral deficiencies can often be detected by specific symptoms such as chlorosis 【loss of chlorophyll resulting in yellow or white leaf issue】, necrosis 【isolated dead patches】, anthocyanin formation 【development of deep red pigmentation of leaves or stem】, stunted growth, and development of woody tissue in an herbaceous plant.
Paragraph 3 Much of the research on nutrient deficiencies is based on growing plants hydroponically, that is, in soilless liquid nutrient solutions.
Paragraph 4 While mineral deficiencies can limit the growth of plants, an overabundance of certain minerals can be toxic and can also limit growth.
Paragraph 5 Scientists have known for some time that certain plants, called hyper accumulators, can concentrate minerals at levels a hundredfold or greater than normal.
Paragraph 6 Only recently have investigators considered using these plants to clean up soil and waste sites that have been contaminated by toxic levels of heavy metals - an environmentally friendly approach known as phytoremediation.
题目:
Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some answer choices do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.
Plants need to absorb certain minerals from the soil in adequate quantities for normal growth and development.
1. Some plants are able to accumulate extremely high levels of certain minerals and thus can be used to clean up soils contaminated with toxic levels of these minerals.
2. Though beneficial with lower levels, high levels of salts, other minerals, and heavy metals can be harmful to plants.
3. When plants do not absorb sufficient amounts of essential minerals, characteristic abnormalities result.
4. Because high concentrations of sodium chloride and other salts limit growth in most plants, much research has been done in an effort to develop salt-tolerant agricultural crops.
5. Some plants can tolerate comparatively low levels of certain minerals, but such plants are of little use for recycling nutrients back into depleted soils.
6. Mineral deficiencies in many plants can be cured by misting their roots with a nutrient solution or by transferring the plants to a soilless nutrient solution.
正确选项是123。不难发现,选项1对应第5和6段;选项2对应第4段;选项3对应第2段。这是因为,所谓的文章主要信息,其实就是某一段或几段的主旨信息。因此,如果有的选项不确定,可以回到文中把每段的主旨信息找到,作为判断的依据。
托福阅读备考要清楚的三个问题
托福阅读复习时间安排
关于复习的时间安排:弄完词汇以后,就应该着手突击一下阅读了。如今各种各样的模拟题犹如英语辅导班一样大量涌现。不会出现我们早期考生有题舍不得做的情况了。但也不能太急功近利,单词没弄好就硬上阅读,有时候会适得其反。用1周的时间大量的突击,也是对单词的一个巩固。找到感觉以后就可以开始下面的复习了。复习听力口语作文的日子里,每天一定要少做3篇文章的题量,按照考试的时间要求,千万不可放松。做得多了,就可以把阅读当作一种放松了。ETS的托福阅读文章能教给我们各种学科的基础知识。
托福阅读必须要读懂每字每句
托福阅读考试中许多考生认为阅读文章时必须要读懂每字每句,事实上,这是不必要的。托福阅读考试中,即使遇到陌生的词,但是根据上下文的意思以及自己的一些常识判断,也不太会影响对文章的理解。特别是托福阅读这种题目涉及面广,信息量大的形式,掌握阅读和答题的技巧,对在托福阅读考试中是会有很大帮助的。
在托福阅读中,甚至可以扩展到ETS所有考试的阅读题目中,如果要用一个词来概括的话,那就是paraphrase,意译。无论是题干还是正确选项,大都能在原文中找出一句话来与之相对应。即题目是原文的意译。这种意译是通过同义词来完成的。即题干中多用近义词来对原文中的句子进行替换,来达到提出问题或者提出正确答案的意思。准确把握意译,是多数题目中准确在原文中定位信息、或者在迷惑选项中选出正确的那个,都有着重要的作用。
托福阅读先看题目还是先看文章
关于先看题目还是先看文章的问题。也就是做题时间安排的问题。在此问题上我与有的朋友也有过争执。我个人习惯是先用5—7分钟的时间通读全文,然后平均每个问题有1分钟的时间来回答。由于对问题的回答建立在了熟悉全文的基础上,每个问题又有足够的时间返回全文,每个选项都一一进行斟酌。我认为这样准确率比较高。但有的朋友本着居家过日子的心,认为1000多字的文章只出十几个题,必然有一些信息是没用的。这样通读全文就会浪费掉一些时间,不如先看题再回去找来的痛快。每个人都应该通过考前大量的练习来制定出为适合自己的方法。
专业托福词汇怎么积累
1. 托福词汇阅读更偏向专业性质的,主要是由于托福考试目的是看考生的英语水平可不可以计划证它在大学中顺利学习专业知识,所以考察的内容更是偏重在学术上,但是阅读文章同样是从大学课本的简易内容中选取。所以在背单词的时候对于学术词
2.托福阅读考察的专业词汇难度上有限制。这点是很自然的,由于托福是一门英语水平考试,但又并非是专业考试。难度较大的专业词汇在阅读里真的会出现,但根本不会考察内容,同时它的意思能够更加容易地猜出来。
3. 托福阅读要求有6以上的词汇量,同时还要去记忆相对常用的专业词汇,但一定别将精力都放到死抠生僻的专业词汇上,由于那并非是托福阅读考察的内容。因此托福阅读词汇备考要有针性,既不能轻视,也不能乱背一通不加选择的背。找到备考重点,托福阅读就可能拿到满意的分数。
