Tornadoes are nature's most violent storms, which can cause deaths and destroy a neighborhood in seconds. A tornado appears as a funnel-shaped (漏斗状) cloud from a thunderstorm to the ground with whirling (飞快移动) winds that can reach 300 miles per hour. Damage paths can be over one mile wide and 50 miles long. Every state is at some risk from this disaster.
Some tornadoes can be seen clearly, while rain or nearby low-hanging clouds obscure others. At many times, tornadoes develop so rapidly that little, if any, advance warning is possible.
Before a tornado hits, the air may become very still. A cloud of debris (散片) can mark the location of a tornado even if a funnel can not be seen. Tornadoes generally occur near the edge of a thunderstorm, when the strong wind may die down. It is not uncommon to see clear, sunlit skies behind a tornado.
The following are facts about tornadoes:
The average forward speed of a tornado is 30 MPH, but may also vary from still to 70 MPH. Debris is picked up or a cloud forms in the funnel.
The average tornado moves from southwest to northeast, but tornadoes have been known to move in any direction. Tornadoes are most often reported east of the Rocky Mountains during spring and summer months.
Tornadoes can happen together with tropical storms and hurricanes as they move onto land. Waterspouts are tornadoes that form over water.
The tornado season in the southern states of America is March through May; in the northern states, it is late spring through early summer. Tornadoes are most likely to occur between 3 p.m. and 9 p.m., but can occur at any time.

【题目】根据短文理解,选择正确答案。
Paparazzi, (狗仔队)or “paps”, are photographers who take pictures of famous people when they are not at the center of public attention. Paps are different from professional photographers or journalists because they never take ordinary photos.
The goal for paparazzi is to get pictures that no one else will get and then sell the pictures to the buyer who offers the most money — normainly a small newspaper, magazine or website.
There is no law against paparazzi taking pictures in public places. However, there are laws that protect certain individuals. For example, child protection laws stop improper pictures of anyone under 16 from being published.
There is also no law that stops paparazzi from following celebrities(名人) and taking their pictures either. However, if paps are secretly following them and taking pictures of their faces, they could get into trouble.
Most paparazzi hang out on streets and hot spots for celebrities, waiting for the opportunity to take a picture of a star. Many stay on the streets until the early hours of the morning when celebrities are leaving nightclubs and looking a little worse for wear. However, some have other ways to make sure they get pictures. Many paps are in contact with “informers” who know the locations of celebrities at any given time. They then pass the information on to paparazzi. An informer could be anyone — from a restaurant waiter to a salesman.
Most of the time, paparazzi get a bad reputation for following celebrities. But sometimes stars or their managers will contact paps themselves and tell them exactly where and when they will go. What a love-hate relationship between paparazzi and celebrities!
