When salmon （大马哈鱼）and steelhead don't get the cold water they need, it costs them more energy to survive. Their reproductive success can be reduced and they become more vulnerable to disease. "And in the worst case, when water temperatures get too high, it can lead to death, says Joseph Bogaard, executive director of the Seattle-based nonprofit Save Our wild Salmon Coalition.
That's what happened in the hot summer of 2015, when temperatures all over the Northwest rose quickly and about 250,000 adult sockeye salmon died in the Columbia River Basin. Many scientists refer to that year as a dress rehearsal for climate change. The clear trend is rising water temperatures and falling returns of endangered salmon. Bogaard says the water temperatures routinely rise above 68 degrees.
Bogaard says that 2015 dress rehearsal scientists refer to will only get worse." Those kinds of conditions are unusual, but they're becoming more common and they're going to become more frequent as we move forward. “He says the Environmental Protection Agency has a model showing dam removal and restoration of the rivers would bring the temperatures down on all but a few days a year. But after 20 years of planning, no federal agencies have taken that advice. Conservation groups appealed and last October, a judge ordered the EPA to take action, mentioning the hot water as violation of the Clean Water Act.
Advocates say dam removal is the only real option to keep endangered fish from going extinct. Many communities near the dams disagree and are concerned about economic impacts if they're taken down.
Save Our Wild Salmon is pressing the governors and members of congress from Washington, Oregon and Idaho to find ways to take action.
8. Which of the following statement is true according to the passage?
A. Lack of enough cold water will make salmon less energetic.
B. High temperature can be beneficial to salmon's productive success.
C. High temperature will result in salmon's immediate death.
D. Lack of cold water will make salmon easier to fall ill.
9. What does the underlined expression "a dress rehearsal" mean?
A. The sign indicating more fish will die due to high water temperatures.
B. The final practice of a show that will be in the performance soon.
C. The trend that water temperatures will rise above 68 degree.
D. The condition that increasing water temperatures are unusual.
10. The obstacle to getting the dams removed is________.
A. that it will influence the economy near many communities.
B. that there are other better ways to save the endangered fish.
C. that many people near the dams refuse to accept the option.
D. that the governors and congress members oppose the solution.
11. What is the best title for the passage?
A. Water temperatures are increasing.
B. The urge to save fish from hot water.
C. Dam removal can surely save fish.
D. Fish are dying out in Columbia.
