Globalcall Communications has grown from a telecommunications solutions provider for local businesses in the greater Seattle metropolitan area to a truly global corporation pro- viding telecommunications solutions for clients both large and small.

[分析] 语义的理解和判断。
根据原文“Globalcall Communications has grown from a telecommunications solutions provider：for local businesses in the greater Seattle metropolitan area to a truly global corporation．”可判断该句中的has grown from…to…句型实际上点明了该公司由起家到发迹的历史，该公司一开始是为西雅图大商圈中的企业服务，而后成长为国际性公司。因此，该题的说法是正确的。
[解题关键] 同义词替换。原文中has grown from与题干中began意思相同，使听者可由此抓住听的重心。

【正确答案】 A

The 350,000-square meter, granite-floored and glass-walled terminal can accommodate 25 million passengers a year and the airport, which has two runways, can handle 1.2 million tons of air freight, the world's third-highest cargo capacity.

[分析] 数字信息的找寻。
根据题干中的数字信息，与原文相关处作对照，发现细节均相符，因此该题的说法是正确的。
[解题关键] 1)根据题干特点抓住原文数字信息重点听；2)同义词替换，在相关信息处，原文中数字修饰的中心词“freights”与题干中使用的“cargo”意思相当，均指“货物”。

【正确答案】 B

【答案解析】[解析]
U.S. scientists discovered that the soft orange glow of a common Caribbean coral comes not from the coral itself but from bacteria that live inside it. And the bacteria not only give the coral a little nightlight, but they also break down seawater to help nourish the coral.

[分析] 事实细节的找寻和判断。
根据题干，需要与原文核对的细节有两处：1)某种细菌是否发出橘黄色的光；2)该细菌是否阻止海水向珊瑚提供养分。根据原文“the soft orange glow…but from bacteria that live inside”可知，题干中第一处细节与原文相符；根据原文“the bacteria…break down seawater to help nourish the coral”即“该细菌还可分解海水，使其更有助于为珊瑚提供养分”，由此可见，第二处细节与原文说法不符，因此该题的说法是错误的。
[解题关键] 掌握反义词的识别，有助于迅速解题。原文中的help与题干中的prevent…from是反义词。

【正确答案】 B

【答案解析】[解析]
Now, text messaging is increasingly being used by UK hospitals to remind patients about outpatient appointments— and could potentially save the National Health Service millions of pounds every year. Ealing Hospital in West London sends 20 texts per day, reminding the patients in advance of the date and time of their appointment. Before using the text messaging system, the hospital relied solely on sending patients a letter as a reminder.

[分析] 事实细节的找寻和判断。
将题干中关键词与原文对照，发现没有short messages或其相近的表达。原文出现的核心词是text messaging。由此可见，题干的说法是错误的。
[解题关键] 排除干扰信息的影响。题干中message与原文中频频出现的messaging，在形式上非常相近，听者会因其相近而忽略其附加内容，造成判断的失误。

【正确答案】 A

【答案解析】[解析]
There's no doubt that athletes are playing hard enough to suppress immune defenses. The normal population in Australia expects to get between three and four upper respiratory infections each year. But if you look at groups of elite athletes, about 15 percent of those athletes can have six or seven or more, even up to 11 or 12. They seem to get more vulnerable as they train harder.

[分析] 比较结构的表达和判断。
原文中关于得呼吸道感染的比较表达有两处：1)The normal population...get between three and four...而运动员，尤其是优秀运动员却“have six or seven or more，even up to 11 or 12”，由此可见，优秀运动员的得病几率更高；2)they seem to get more vulnerable as they train harder．即“这些运动员们训练得越刻苦，身体越脆弱”。从这两处都可推测出题干的说法是错误的。
[解题关键] 1)熟悉比较结构的表达法。表示比较的手段很多，可以通过固定结构，也可通过统计数字作对比；2)掌握信号词，判断上下文逻辑关系，有助于迅速解题，如原文在说明普通人群得呼吸道感染的几率后使用了单词but，表明后面的对象的事实肯定与前面不一样，从该词的使用，也可猜测出优秀运动员得病的几率更高。
