Many people like the feeling of the gentle wind in spring. Many people like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive (毁灭性的)．
Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict (预测) how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.
Predictions are improving. “We’ve gotten better over the years, especially the last few years，” says Phil Klotzbach, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the
storm to a new direction. “For a hurricane to happen, conditions have to be just right，” Klotzbach says.
First, the ocean water needs to be warm enough so that it evaporates (蒸发) and rises into the air. As it rises, the vapor cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.
If wind speed reaches 40 miles per hour, the system is called “tropical storm”， and it gets a name. At 75 miles per hour, it becomes a hurricane.
The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.
Section_Ⅰ Introduction & Reading — Pre-reading
[原文呈现]
What Is a Tornado①？
A tornado is a rotating② column③ of air from a thunderstorm④ to the ground. The most violent⑤ have winds of more than 400 kilometres per⑥ hour. Almost all of them occur⑦ in the US, in the area from Texas in the southeast to South Dakota in the north.
Tornadoes can pick up⑧ cars, trains and even houses and put them down in the next street — or even in the next town. They can take the fur⑨ off⑩ the back of a cat and the feathers⑪off a chicken. They can destroy houses, but leave the furniture⑫ inside exactly where it was⑬.
On average⑭， there are 800 tornadoes in the US each year, causing⑮ about 80 deaths and 1,500 injuries⑯. The worst tornado of all time⑰ occurred in 1925, affecting three US states⑱： Missouri, Illinois and Indiana. By the time it ended, more than 700 people had been killed and 2,700 had been injured.

[我的发现]
(1)②句采用了过去完成时，其构成形式为：主语＋had_done。
(2)①③句采用了过去完成时的被动语态，其构成形式为：主语＋had_been_done。
(3)④～⑦句均为直接引语变间接引语的句子，在变间接引语时，人称、时态、语序等方面都要做相应的变化。
(4)由⑦句可知，若直接引语为客观真理，变间接引语时，时态不变。
一、过去完成时的被动语态
1．概念：过去完成时的被动语态表示动作在过去某一时刻或某一动作之前已完成，且主语与谓语动词存在被动关系。
2．构成
(1)肯定结构：主语＋had been done
(2)否定结构：主语＋had not been done
(3)疑问句结构：Had＋主语＋been done ...特殊疑问词＋had＋主语＋been done
3．用法
(1)在told, said, knew, heard, thought, found等动词后的宾语从句中，表示宾语从句中的动作已被做完时，要用过去完成时的被动语态。
He heard that the tickets had already been sold out.
