大学英语六级（2013年12月考试改革适用）模拟试卷309
作文
1.For this part, you are allowed 30 minutes to write a short essay based on the picture below. You should focus on the impact of social networking websites on students. You are required to write at least 150 words but no more than 200 words.
As the picture shows, when students are back to school after summer vacation, they are required to share what they have done because not all of their friends or family members follow them on such social networking websites as Twitter and Facebook. We can see from the picture the adverse impacts of these websites on students: lack of verbal sharing.
Nowadays, students would rather have what they’ve experienced shared via virtual space than talk with their intimate friends or parents. Sorrow and happiness are all recorded in implicit pictures and words. And it appears that the only way to show our care and tenderness is to give comments or thumbs up. However, the very excitement or the subtlety at the moment of occurrence can hardly be known from a glance of those pictures and words. It should be detailed by a more amiable communication.
Phones now have become the dominant medium for people to know about each other and to share daily events with friends or relatives apart. But an addiction to sharing via virtual space can only lead to a decrease in the ability to consolidate close bonds with the people we truly love.
解析： 题目要求考生围绕社交网站对学生产生的影响进行论述。根据题目要求，文章的结构可安排如下：
第一段：准确且简要地描述漫画内容并开门见山指出社交网站会导致学生缺乏“口头分享”。
第二段：从当下人们都习惯在虚拟的社交网络分享生活这一普遍的现象切入中心论点，分析这种速食式分享无法真正使人们加深情感，并指出只有通过亲近的沟通和交流才能使亲友领会当时的微妙与激动。
第三段：重申这种现象的普遍性，接着点题，指出如若沉迷网络分享，我们与亲友的沟通能力将会下降。
词汇理解
Secondhand smoke is accountable for 42,000 deaths annually to nonsmokers in the United States, including nearly 900 infants, according to a new study. Altogether, annual deaths from secondhand smoke【C1】______nearly 600,000 years of potential life lost—an average of 14.2 years per person—and $6.6 billion in lost productivity,【C2】______to $158,000 per death, report the researchers. The new research reveals that despite public health efforts to reduce tobacco use, secondhand smoke continues to【C3】______a grievous toll on nonsmokers.

2.【C1】
L
解析：空格前的名词中心词是annual deaths，空格后是名词600,000 years，故需填入谓语动词，时态与上一句的is一样是一般现在时，因此是原形。本句说明二手烟的危害，句意为：每年二手烟引起的死亡……差不多60万年的潜在寿命损失。空格后是对二手烟引起的损失的具体说明，故填入represent“代表，表示”逻辑合理。take后也可接时间，表示“花费”，常用于it takes sb．to do sth．结构。
3.【C2】
M
解析：空格前的中心词是$6．6 billion这个金额，空格后的$158,000也是金额，故此处应填入分词，与to搭配，说明前后两个数额的关系。amounting与to搭配，表示在意义、价值等方面“等同，接近”，填入后逻辑合理，句子表示：二手烟造成66亿美元的生产力损失，等同于人均损失15．8万美元。adhering也可与to搭配，但意为“黏附；遵守；追随”，不符合上下文语境。
4.【C3】
G
解析：根据空格前的continues to，可判断此处应填入动词原形，与其后的toll搭配。句子应表达二手烟对非吸烟者仍有严重的影响。take a toll on为固定搭配，表示“对……产生不良的影响”。
5.【C4】
C
解析：空格位于be动词are和表语very large之中，故应填入副词。上一句提到吸烟的人越来越少，许多人也已经改变了生活方式，本句说但我们的研究显示二手烟的影响巨大。nonetheless意为“尽管如此，仍然”，相当于still，呼应上文but。
6.【C5】
D
解析：空格前为the，空格后为of从属结构，故需填入名词。句子表示生物指标测量信息使我们能更加准确地评价二手烟对健康与生产力的影响，availability表示“可利用性，可得性”，符合上下文语义，表示生物指标测量信息的“获取”。take也可作名词，指鱼或动物的“捕获量”，跟信息获取的语境不符。
7.【C6】
I
解析：此处需填入修饰illnesses(疾病)的词，可以是形容词、分词或名词。根据
