Conversation Two
M: Is that a map? Are you going sailing or something?
W: I wish. It's a hurricane-tracking chart. [22]It's a map of tropical ocean areas southeast of us. It follows the development of tropical storms, even hurricanes. They develop and move around the Atlantic in Caribbean and here on Florida coast. We get hit a lot by those in July or August, at least winds or rain.
M: Do you think that the tropical storm is on the way?
W: Too early to tell, but we need to be prepared. The radio mentioned possible evacuation routes.
M: Really? It's that serious?
W: You'd better believe it. Late summer is hurricane season. The television updates locations and speeds every hour.
M: What did they say is out there now?
W: A couple of tropical depressions, two storms and two hurricanes.
M: [23]What's the difference?
W: [23]Wind velocity. A depression is least serious actually, and a hurricane is the most serious.
M: How serious are the winds in hurricanes?
W: They have sustained winds of 74 miles per hour and up.
M: What are the names on the map? David, Arlene, Francisco, and Gina.
W: [24]You know weather forecasters give the hurricanes the names of people to make storms easy to identify.
M: I wonder what the status of the storm is now.
W: [25]You shall turn on the television, and it has the best coverage. There is an up-date coming up in five minutes.

Questions 22 to 25 are based on the conversation you have just heard.
22. What is the conversation mainly about?
正確答案：A
解析：對話開頭女士就說到，“這是一張颶風路線圖”，之后兩人就一直討論颶風問題，故A正確。對話提到過幾個颶風的名字，也說到風速是區別熱帶低壓（tropical depressions）、暴風（storm）與颶風（hurricane）的指標，最后還提到電視上會有對颶風的最新報道，B、C、D均是一些細節，但它們都不是對話的主題，都不對。正確答案特征：在對話開頭就會提及，往往在對話中多次提到。
23. Which is true about a depression, a storm and a hurricane?
正確答案：B
解析：對話中女士提到了低氣壓、暴風和颶風，男士就問“它們有什么區別”，女士說，其區別在風速。故B正確。A中的the time they land應改為wind velocity或the speed wind travels；C中的least應改為most，D中的less應改為more。
24. Why are hurricanes named after people?
正確答案：B
解析：男士在問到地圖上的人名時，女士解釋說：“天氣預報工作者給颶風取上人的名字，以便使它們容易區別開來。”B項中的tell apart即對話中的identify之義，故B正確，含有因果、目的等關系的語義突出之處常設考點。|
25. What are the man and woman going to do next?
正確答案：D
解析：對話結尾處女士說，“你該打開電視，它報道最清楚。5分鐘后就會有最新報道了。”因此對話中的兩人是準備看電視上的天氣預報，選D。四個選項的動詞及其賓語構成的搭配，一般由動詞確定答案（原詞再現或同義替換）。本題原文是turn on the television，應為D而不是B！這里應根據名詞TV選出答案！
