Events such as hurricanes, earthquakes, floods, volcanic eruptions, and tornadoes are all natural disasters. They are mostly related to the weather. Some are predictable ----like a hurricane. Some, like an earthquake, surprise us. It is necessary for us to learn about them, so we can be prepared!

Flooding happens during heavy rains, when rivers overflow, when ocean waves come onshore, when snow melts too fast or when dams or banks break. Flooding is the most common of all natural disasters.

Hurricanes are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation(蒸發(fā)) from the sea water increases their power.

Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars.

Tornadoes are nature’s most violent storms. Tornadoes must always be taken seriously. Tornadoes can be very dangerous ---- sometimes even deadly. They come from powerful thunderstorms and appear as moving. Tornado winds can reach 300 miles per hour. They cause damage when they land the ground. They can damage an area one mile wide and 50 miles long.

While thunder won't hurt you ----lightning will! So it's important to pay attention when you hear thunder. Thunderstorms happen mostly in summer and every thunderstorm has lightning. Lightning can strike people and buildings, which is very dangerous.

Thunderstorms affect small areas when compared with hurricanes and winter storms. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes.

A volcano is a mountain with a large opening at the top through which melting rock, steam, gases escape from time to time with violent force from inside the earth. When pressure increases, eruptions occur. Gases and rock shoot up through the opening fill the air with small pieces. Eruptions can cause lava flows, hot ash flows, mudslides, falling ash and floods, which is likely to knock down entire forests, cause floods and earthquakes. Fresh volcanic ash can cause damage to the lungs of older people, babies and people with respiratory problems.

64. From the passage, we know that ______.

   A. all natural disasters can be predicted 

   B. all natural disasters are connected with the weather.

   C. human beings can do nothing with natural disasters

   D. the more we know about natural disasters, the less we will suffer.

65. Which of the following is NOT true according to the passage?

   A. Flooding is the most common natural disaster. 

   B. Hurricanes and tornadoes can land the ground and cause damage.

   C. Thunder can strike people and buildings.           

   D. Fresh volcanic ash can cause illnesses.

23. In modern times, people have to learn to _____ all kinds of pressure although they are    

leading a comfortable life.

A.keep with    B. stay with    C. meet with      D. live with

31. There was a teapot shaped like a duck, out of ____open mouth the tea was supposed to come.

A. which            B. its                  C. that                 D. Whose

The Princess and the Frog is a fairy musical that          the days when Walt Disney was a person, not a brand.

   A. was dated back to         B. dates back to   

C. has been dating from        D. had dated from

  Things similar continuously happened in Haiti and Chile．Thousands of people were

buried in the earthquake and lost their fives．What if we could have warned them? People are always trying hard to find a way of preventing building collapsing(坍塌)．Better materials and technology help，but are not a solution．Just like humans，a building has its own life circle from  “birth” to “death”．If we know when a building is going to collapse，we can repair it in advance or get out before it falls．

    Now, scientists at the University of Illinois ha、，e developed a material that turns red before it breaks．The invention could be used in things like climbing ropes，or bridge supports．The secret behind the color-changing material is a type of molecule(分子)．A molecule is a group of atoms held together by chemical bonds(化學鍵)．Imagine you and your friends standing in a circle，holding hands．Each person stands for one atom，your hands represent the bonds，and the entire circle represents a molecule．If one person lets go of his or her hands，the molecule changes color．The research team put the molecule into a soft material．When the researchers stretched(拉長) the material：it turned bright red a few seconds before it broke into two pieces．

When they repeatedly stretched and relaxed the material，without breaking it，it only turned a little red．

The major problem is，light can get rid of the red color．When the team shone a bright light on the molecule，the broken bond was fixed，and the color disappeared．If bright fight keeps the red color from appearing，the material’s warning system will be useless．Scientists still have a lot of work to do before the color-changing molecule can be used outside the lab．

49. The passage mainly about

A. a way of preventing building from breaking down

B. a series of earthquakes in Haiti and Chile

C. a way of warning before buildings collage

D. a newly-discovered structure of a molecule

50．According to the passage，we call conclude that

A．there are problems to solve before putting the new material to use

B．scientists have found the life circle of buildings from “birth” to “death”

C．bright fight makes the red color visible to human eyes

D．the new material is unlikely to be used in building bridges

51．The color-changing molecule can

A．make building materials much stronger

B．help building materials get stretched if necessary

C．prevent the earthquake from killing people

D．remind people to leave buildings before they fall

52．The warning system is based on the fact that

A．red color won’t show up when it meets bright fight

B．a(chǎn) material with a certain type of molecule Can turn red when s廿etched

C．a(chǎn) building has its own life circle of “birth”to“death”

D．the broken bond will fix itself when a molecule meets bright fight
