Two of the most dangerous storms which affect America are hurricanes and tornadoes. They are very much feared by anyone who may live in the path of their destruction.

Every year homes are destroyed by their fury anf often lives are lost. Most people who live near the coast are forced to evacuate their homes and to move to safer areas until the storms passes. Floods are caused along the coast by both the heavy rain and a storm tide that is considerably above normal water level. The high winds, coastal flooding and heavy rains associated with a hurricane cause enormous damage. Hurricanes usually develop between July and October. Once they hit land they tremendous power with driving rain and wind.

Tornadoes are violent low-pressured storms. These storms occur most often during the summer months are noticeable by their strong wind and lack of rain. The sky turn black as dust is sucked up into the air. Tornadoes are capable of lifting quite heavy objects from the ground. They can pick up trees and cars right into the air and even uplift heavier objects such as homes and trains.

Both hurricanes and tornadoes cause millions of dollars worth of damage to life and property every year. Today they can be predicted more easily than in the past, but they can't be stopped or ignored.

Read the passage below and choose one correct answer for each question.

Global warming and cooling have occurred naturally throughout history. But in the last 200 years, humans’ uses of fossil fuels and clear cutting of forests have increased the amount of carbon dioxide and other gases in the atmosphere. These gases trap some of the radiation from the sun which then increases the Earth’s temperature. Given the current state of environmental pollution caused by human activities, scientists believe the average temperature of the earth may increase 1-2 degrees Celsius which put simply, means some places will get much hotter and some much colder. At the same time, this overall warming effect means more frequent and more intense weather systems, especially in terms of flooding and drought.    

Viet Nam is one of the most vulnerable environments due to its location on the planet. It is already subject to some of the earth’s most powerful weather systems and the increased frequency and intensity of storms will affect it often and directly, especially in coastal areas where most people live. Various estimates have been made as to the possible impacts. The most directly affected sector will be agriculture, which is very sensitive to flooding and the effects of extreme weather.

Viet Nam has the advantage of coming relatively late into the industrialization, urbanization, and modernization process. This means it can avoid many of the mistakes made by wealthier industrial countries. For example, wireless communication networks can be built from the start rather than installing lines that can easily be destroyed in extreme weather. Cities can be designed and located in less vulnerable locations. Climate-friendly building codes and standards can be created that are both more efficient and less prone to heat stress, wind damage, and flooding. Climate friendly transport systems, especially public transport, can be adopted.

But rising sea water caused by global warming is now increasing the salt content of the river water and (5) _______the livelihoods of millions of poor farmers and fishermen.

A. threatens

B. threaten

C. threatening

D. threatened
