0331托福綜合寫作的閱讀：
Hooligans太平洋細齒鮭數量減少了，有以下三個原因。
1. Upperstream dam 限制了水流，沒有sand和gravel來附著產出的卵。
2. By catch，漁夫捕魚的時候順便把Hooligan抓了(fishers use nets to capture shrimps and hooligans will be caught by accident in this way)。
3. 其他魚，比如hake游進來跟Hooligans競爭食物。

0331托福綜合寫作的聽力：
這三種原因都有解決方式。
1. Temporary adjustment Hooligans only hatch in spring, so we can let more water go through dams to carry more sands and gravel;
2. Use a small bright light along the rivers which the hooligans are sensitive to but the shrimps are not；
3. Add more food, like krill (這是the Pacific hake和hooligan共同的食物) into rivers for hooligans by humans，這樣就能減緩食物競爭。
