Unit 4 单元主题语篇训练

Ⅰ.完形填空

I've been into environment­friendly things for ages, which started when I was 13 and my favorite teen magazine   1   in the mail with a “Save the Earth, Girl！” cover. I remember it   2  ！ It was filled with all sorts of easy   3   to go green.

Among many of the   4   I learned that day: turning off the water while you brush your teeth   5   200 gallons of water every year — per person! I started doing that   6  . I mean, it is kind of a big deal considering Earth doesn't have an unlimited   7   of fresh water.

My parents were also   8   for recycling and reusing, so we became the ones who   9   rejected containers and used them for   10  ， and the ones who carried our own bags to the grocery store and our own   11   to the coffee shop. I knew it was the right thing to do for the environment.

Later, I tried to let my   12   flag fly! I either called out to whoever littered in public or collected magazines from my friends to   13  . Then the strangest thing happened: people started   14   me. One by one, my friends began to turn off the lights, buy recycled notebooks, and   15   paper back into the printer to make use of the other   16  . It's not that they were so   17   about the environment, but they were drawn to my confidence.

I'm wild about environmental protection and would stand   18  ， saying, “Yeah, this is what I'm into.”   19   others don't share your enthusiasm, they will envy your confidence and want to be like you, and that means   20   your example.

Ⅱ.阅读七选五

To make sure that the foods are delicious and safe, the Food and Drug Administration provides several tips to reduce the risk of the most common foodborne illnesses.

  1   Bacteria can spread throughout the kitchen and get onto cutting boards, knives, and counter tops.To avoid the risk of foodborne illnesses, people should pay special attention to the handling and preparation of foods.

Keep foods apart.Bacteria can spread from one food product to another.This is especially true for raw meat and seafood.  2 

Put foods in a refrigerator without delay.Public health officials advise consumers to refrigerate foods quickly.  3   Refrigerators should be set at 40 degrees F and the freezer at 0 degrees F, and the accuracy of the settings should be checked now and then.

Keep foods at a safe temperature during thawing (解冻)．Let's take turkey for example.Thawing the turkey completely before cooking is important and necessary to reduce the risk of foodborne illnesses.  4   For example, a 20­pound turkey needs two to three days to thaw completely when thawed in the refrigerator at a temperature of no more than 40 degrees F.

  5   Foods are properly cooked when they are heated for a long enough time and at a high enough temperature to kill the harmful bacteria that cause foodborne illnesses.

A．Cook to proper temperatures.

B．So keep them away from ready­to­eat foods.

C．Wash hands and food contact surfaces often.

D．Washing hands before meals is good for health.

E．So allow the correct amount of time to thaw a whole turkey.

F．The turkey is done when the temperature reaches 180 degrees F.

G．That's because cold temperatures stop most harmful bacteria growing.

语篇解读：本文是一篇说明文。文章主要介绍了几种避免食源性疾病的方法。

1．选C　根据空后的内容可知，细菌会在整个厨房内传播，切菜板上、厨房刀具上和厨房台面上都可能会有细菌。C项中的“food contact surfaces”与下文中的“cutting boards, knives, and counter tops”相对应，故C项“经常洗手并清洗接触食物的物体表面”符合语境。

2．选B　根据本段的主题句“Keep foods apart.”可知，本段主要讲的是要把食物分开放置，再结合空前两句可知，生肉、海鲜特别容易传播细菌，因此应该把它们与其他食物分开放置。故B项“因此要把它们和立即可食的食物分开放置”符合语境。B项中的“them”指代的就是上文中的“raw meat and seafood”。

3．选G　根据本段的主题句“Put foods in a refrigerator without delay (将食物立即放进冰箱)．”及公共卫生官员建议人们快速冷藏食物的内容可知，空处应该是说明这样做的原因，故G项“那是因为低温可以阻止最有害的细菌生长”符合语境。

4．选E　根据空前一句可知，在烹饪前完全解冻火鸡对降低患食源性疾病的风险很重要，再结合下文中所举的例子可知，空处说的应是要有一定的时间来使一整只火鸡解冻。故E项符合语境。

5．选A　根据空后的内容可知，当食物被加热到足够的时间时，食物就被做好了，而且足够高的温度能够杀死那些引发食源性疾病的细菌。因此本段主要讲的应是烹饪时要达到一定的温度，故A项符合语境。

tips 利用代词的指代关系解阅读七选五

在英语表达中，代词出现的频率极高，代词的作用无非是指代前面提及的名词或形容词概念，或指代前文的某个句子。如果设空处后一句或选项中出现代词(尤其是人称代词、指示代词或替代词)时，往往可根据代词的指代关系来解题。指代相关是指文中空白处前后句中的某个名词或代词与正确选项中的某个代词或名词之间存在指代关系。此时，准确理解该代词的指代范围或内容是解题的关键。例如it可指代单数名词或整个句子；they或them指代复数名词；one指代单数可数名词；that指代不可数名词或句子；this指代单数名词或句子；these或those指代前句的复数名词。

例如上文第2题，B项中的“them”指代的就是上文中的“raw meat and seafood”。　　　　

Ⅲ.语法填空

Humans share Earth with many different kinds of wildlife. However, many of our animal friends may not be around for much   1   (long)．

According to the Living Planet Report released by the World Wildlife Fund (WWF) in October, the populations of animals   2   (fall) by an average of 60 percent since 1970. And one of the biggest causes of wildlife losses   3   (be) human activity. Three quarters of the world's land is   4   (large) affected by human activity. Many natural habitats have been destroyed to create farmland.

“The astonishing decline   5   wildlife population is a reminder and perhaps the ultimate sign of the pressure we put on the planet，” Marco Lambertini, the general   6   (direct) of the WWF, wrote in the report.

WWF has called on world governments and businesses   7   (strike) a deal to protect people and nature. To protect   8   (endanger) animals, measures have been taken in China and progress has been made,   9   more efforts are still needed to protect wildlife in China and around the world.“We are the first generation to know we are destroying our planet and the last one   10   can do anything about it，” WWF UK Chief Executive Tanya Steele told CNN.

语篇解读：本文是一篇说明文。文章主要讲述了由于人类的活动，许多动物濒临灭绝，因此我们应该采取措施保护它们。

1．longer　考查形容词比较级。分析该句可知，设空处前的much修饰形容词比较级，故填longer。

2．have fallen　考查时态和主谓一致。分析该句可知，since引导时间状语从句时，前面的主句用现在完成时，且主语the populations of ...为复数形式，故填have fallen。

3．is　考查主谓一致。分析该句可知，主语为one of the biggest causes of wildlife losses，当one of位于句首时，谓语用单数，且此处描述客观情况，故填is。

4．largely　考查副词。分析该句可知，设空处应用副词修饰动词affected，故填largely。

5．in/of　考查介词。此处of译为“属于，关于”，表示所属关系；而in译为“在……之内”，表示领域或范围，所以of和in都适用，故填in/of。

6．director　考查名词。根据Marco Lambertini可知，general后接表示人的名词，the general director译为“总干事”，应用名词形式。故填director。

7．to strike　考查不定式。设空处使用不定式作目的状语，故填to strike。

8．endangered　考查形容词。设空处应用形容词修饰其后名词animals。故填endangered。

9．but/yet　考查连词。分析该句可知，前后两句构成转折关系，but和yet都译为“但是，然而”，表示转折和对照关系。故填but/yet。

10．that/who　考查定语从句。该句为定语从句，先行词为the last one，在从句中作主语，此处one指代generation，应使用关系代词that或who。
