    The Salton Sea in California is actually a salty inland lake. The level of salt in the lake’s water

    The level of salt in Salton Sea in California has been increasing for years, and the water will be unsuitable for populations near the sea if people do not take any solutions. This reading provides several ways to prevent bad things happening, however, the lecturer does not agree about those options.

    The first option is pumping water from the lake to provide to other facilities, so that the water can be evaporated into stream and cool down to become salt-free water. But the lecturer argues that pumping water can also bring other health risks, for example, it can bring other types of chemicals from the bottom of the sea. Some of this chemical are harmful and can dissolve into the air. It will cause some unpredictable problems if people breathe them in.

    In addition, the solution to dilute the salt level by pouring water from the ocean is also unacceptable. Because it would cost too much money by constructing such long pipes to take water from the ocean, and the local govenment may not have enough money to pay for the resources.

    Finally, the reading said some walls can be constructed by dividing the lake into several sections to let salinity go into smaller sections. However, if some activities happened like earthquakes, walls would be destroyed instantly. So, it is only works in a short term.

    Reading Material:

    The Salton Sea in California is actually a salty inland lake. The level of salt in the lake’s water—what scientists call its salinity—has been increasing steadily for years because the lake’s water is evaporating faster than it is being replaced by rainfall or rivers. If the trend continues, the lake’s water will soon become so salty that the lake will be unable to support fish and bird populations. The lake would then become essentially a dead zone. Fortunately, there are several ways to reverse the trend that is threatening the lake’s health.

    One option is direct removal of salt from the lake’s water in special desalination facilities. Water from the lake would be pumped into the facilities and heated. This would cause the water to evaporate into steam, while salt and other materials dissolved in the water would be left behind. The steam would then be cooled down and returned to the lake as salt-free water. Gradually, the high salt levels would be reduced and the lake’s overall health would be restored.

    Another possible solution is to dilute the salt level in the lake with water from the ocean. Since water in the Pacific Ocean is 20 percent less salty than water in the lake, bringing ocean water into the lake would decrease the lake’s salinity. The ocean water could be delivered through pipelines or canals.

    Yet another solution would be to control the lake’s salinity by constructing walls to divide the lake into several sections. In the smaller sections, salinity would be allowed to increase. However, in the main and largest section, salinity would be reduced and controlled by, among other things, directing all the freshwater from small rivers in the area to flow into that main section of the lake.

    The Salton Sea in California is actually a salty inland lake. The level of salt in the lake’s water—w

    The level of salt (salt level   )in ( the  )Salton Sea in California has been increasing for years(  . ), ( As a result,   )and the water will ( would  )be( become  ) unsuitable for ( the  )populations near the sea( lake  ) if people do( did  ) not ( failed to  )take any solutions( measures  ). This reading (passage   )provides several ways to (prevent bad things from happening)( preclude undesirable consequences ). However, the lecturer does not agree with those options.

    (The first option is pumping water from the lake to provide to other facilities so that the water can be evaporated into streams and cool down to become salt-free water.)( Unclear  ) However ( ,  )the lecturer argues that pumping water can also bring (about/result in/lead to   )other health risks. For example, it(this practice   ) can bring ( up  ) other types of chemicals from the bottom of the sea(lake   ). Some of these chemicals are harmful and can dissolve into the air. It will cause some unpredictable problems if people breathe them in.( For example, this measure is likely to bring up harmful chemicals from the lake bottom and then release them into the air, thereby posing health dangers to the people in the vicinity. 

    In addition, the solution (to dilute)( grammatical error )  the salt level by pouring water from the ocean is also unacceptable. Because it( this measure )  would cost too much money( . )  to ( As an illustration, constructing ) construct such long pipes to take water from the ocean, and (goes beyond  ) the local government (‘s budget.  )  may not have enough money to pay for the resources.

    Additionally, diluting the salt content by pouring water from the ocean is financially impractical. Without a doubt, constructing necessary facilities such as the long pipes from the ocean may bring an unbearable burden to the local government. 

     

    Finally, the reading ( passage ) said (suggests that  ) some walls could be constructed by dividing the lake into several sections ( by building walls )  (to let salinity go into smaller sections)( unclear ) . However, if some activities ( natural disasters )  happened , like earthquakes, walls would be destroyed instantly. So, it( this approach )  only works in the short term.
