吴淞中学2019年高三年级上学期一模考备考冲刺讲义
A. It can also be caused by the inappropriate use of fluoride drops or other fluoride supplements.
B. It’s evident that fluoride has negative effects on teeth, especially children’s teeth.
C. So you are right — fluoride can be poisonous if it is swallowed in very large quantities.
D. If a deadly amount of fluoride is taken, immediate first-aid could save a life.
E. That is why they should only have a tiny amount of fluoride toothpaste on their toothbrush.
F. Fluoride toothpastes are advertised too extensively in TV commercials.
I have heard that fluoride（氟化物）can help stop dental decay, but I recently read that it is poisonous. Which of these is true? How can children use fluoride safely?
This question is answered thanks to Dr Marcia M. Rich who practices general dentistry in Newholt. She is also a lecturer at the University and a writer for the monthly magazine Your Dentist Cares.
My answer to the first question is to stress that fluoride works well and is safe when users follow instructions. Young children have a tendency to swallow toothpaste. ___1___ If this simple measure is taken, parents can be confident that children will be protected against tooth decay, and come to no harm.
Almost all medicines can have a negative effect — or even be deadly — if they are not taken as directed. ___2___ It is for this reason that fluoride supplements can only be obtained on prescription from a doctor or dentist.
Taking too much fluoride while teeth are growing can lead to a condition called dental fluorosis（氟中毒）. The most likely cause is the swallowing of fluoride toothpastes by young children. ___3___ For example, when fluoride is already present in drinking water, the overconsumption of it can seldom be avoided. But don’t be too worried, since fluoride overdoses are rare. In fact, I have never heard of any fatal incidents related to the fluoride poisoning.
Scientific studies have shown that fluoride can help to prevent cavities（龋齿）as long as it is used correctly. But it is also true that if fluoride is abused, there is a risk of illness or even death in extreme cases. ___4___ A person who has swallowed a large amount of fluoride will probably start vomiting. If not, the patient should be given milk or antacid and taken to the nearest hospital for emergency treatment.

【知识梳理】
1．6选4的解题指导
此类题型的一般解题步骤是：读题干并确定关键词（中心词)——回到原文中定位关键词——分析定位句——分析题干——确定答案。

具体的解题技巧如下：
（1）用“打包”方法对付乱序
把整组题全部一次性吃透，然后回到原文从头到尾定位。

否则，考生如果按顺序逐题解答，时间会严重不足。

首先，先略读文章，获取文章大意，并提炼所读段落的核心意思（英文关键词）。

其次，浏览6个题干，划出每个题干句子的核心词(注意可能并非是定位词），初步判断该题干与所读段落是否匹配。

最后，划出剩下未匹配题干的核心词，并与剩下的文章交替阅读，直至做完。

（2）“吃透”题干，准确判断关键词（中心词）至关重要
如果没吃透题干，就无法准确判断关键词或中心词，就可能对原文中的重要信息没感觉。

一般来说，题干关键词或中心词为实词以及一些数字、专有名词等。

语句核心词提炼是英文阅读的必备技能之一，是提高阅读效率的必经途径。

要想获得该能力，需要考生在明了基本原理的基础上，配以大量练习方可，但这一能力确实值得考生花大力气训练。

（3）在解题的先后顺序上，采用先易后难的策略
67. C 这些包括了有更高的地位，产生更多的力量，更加自我关注，斗志昂扬和自信。

68. E 直到现在，研究员并没有检查出女性对于姓氏的选择如何影响着其他人看待她的丈夫。

69. A 这些发现也表明了他们也讲批判主义运用到他们的丈夫身上。

70. D 这些婚姻的姓氏的传统不仅仅是传统。

A.It was an enclosed outdoor office space built around a tree in London’s Hoxton Square.
B.More businesses will try this in the future, as advances in technology make it possible to work
anywhere.
C.People want to get outside the office and step away from their cubicle for fresh air.
D.Wind and rain can get in the way of work.
E.If that’s the case, then shouldn’t working outdoors should be as good, if not better, than
looking out the window?
F.But what if you could combine work and nature?
With summer right around the corner for those in northern hemisphere, many are eager to escape the office and spend more time outdoors.
____67____It’s something several cities and companies have been trying to do, creating outdoor spaces where workers can get back to nature, but with all the trappings of the modern office, such as wireless internet, electrical outlets and desks.Not all work is best done at the desk, says Jerry Tate, an architect and partner with London firm Tate Harmer. “Sometimes it’s best to talk at a meeting table, or a coffee shop –there’s no reason why a fair chunk of that stuff can’t be combined with sitting outside,”he says.
In June 2015, Tate, along with artist Natalie Jeremijenko, created TREExOFFICE. ___68___Only eight people could use it at one time, but it was at capacity for the two summers it was in operation. It’s not going up in Hoxton Square this year, but it may go up in Chelsea instead, says Tate.While the project was created to raise funds for the square –companies had to pay a fee to book the space–it was also developed to help workers increase their productivity.
而不是法律意义上的权利right，故选B。

70. 倒数第二段最后一句提及只要在a “reasonable”time就可以退换货，70空后面指出不同店
家时间限制不同“Some…within a week of purchase, while others…a much longer time limit”。

所
以由此得出70空也应与时间有关，除了C之外没有选项与时间有关，同时利用同义词复现“reasonable”也可以定位到C选项。
