【答案】A
【解析】句意:--仓颉什么时候创造了中国的汉字?--大约4000多年前。
A. characters:“characters” 常见意思为 “文字;字符” ,“Chinese characters” 就是 “汉字”,根据问句 “仓颉什么时候创造了最初的中国……”,这里说仓颉创造汉字是符合历史事实的,所以该选项符合题意。
B. furniture:意思是 “家具”,仓颉并不是创造家具的人,所以此选项不符合语境。
C. culture:意为 “文化” ,文化是一个广泛的概念,仓颉主要贡献是创造文字,而不是创造整个中国文化,这个选项不太准确。
D. symbol:意思是 “象征;符号”,虽然汉字也可说是一种符号,但相比之下,“characters” 更直接准确地表达 “汉字” 这一概念,所以该选项也不合适。

B. symbol:意思是 “象征;符号” ,通常强调抽象意义上的象征,比如鸽子是和平的象征(The dove is a symbol of peace.),而 “福” 是一个具体的汉字,用 “symbol” 不太合适。
C. sign:常见意思为 “迹象;符号;招牌;手势” ,侧重于有指示、警示等含义的标志,比如交通标志(traffic signs),与 “福” 字的语境不匹配。
D. mark:意为 “标志;记号;分数” ,常指留下的痕迹、印记等,如纸上的污渍印记(a mark on the paper),也不符合 “福” 字的表达。故选A。

A. imagine 意为 “想象”,强调在脑海中构思、设想事物,与传播坏消息的语境不符.说 “我们可能想象一些不好的东西”,不符合在网上传播消息这个情境。
B. stretch 有 “伸展;拉伸;延长” 等意思,与传播消息毫无关系。
C. discover 意思是 “发现”,通常指发现原本存在但未被人知晓的事物,与在网上传播消息的逻辑不搭。
D. spread 有 “传播;散布” 的意思,放入句子中,“If not, we may spread something bad.” 意思是 “如果不(确保消息真实),我们可能会传播一些不好的东西”,符合在网上传播消息,如果不确认真实性可能会传播不良信息的语境。
2. Because of the Internet, the news seems to________ more quickly than we expected.
A.remain B. spread C. disppear D. stretch
【答案】B
【解析】A. remain 意为 “保持;停留;剩余” 语义不通顺,所以 A 选项错误。
B. spread 意为 “传播”,常用来表示消息、疾病、文化等的传播 ,在本句中,“因为互联网,新闻似乎传播得比我们预期得更快”,符合语境,所以 B 选项正确。 C. disappear 意为 “消失”,用在此处,“新闻似乎消失得比我们预期得更快”,不符合互联网对新闻影响的实际情况,所以 C 选项错误。
