Ⅳ.七选五
(2024·石家庄高一检测)
Wildlife workers in Florida are feeding manatees(海牛) to keep them from starving. 1.F So far, the rescue workers have already given out 25 tons of lettuce.
Manatees are huge sea mammals that can be as long as 4 meters when grown. 2.B In spite of their size, manatees only eat plants that live in the sea.That's one reason why they're sometimes called “sea cows”．They spend most of their time in warm shallow water looking for food.
But Florida's manatees have been on the US government's list of endangered animals since 1967.Most threats to manatees come from humans.One of the biggest problems facing the creatures is boat. 3.E Manatees are curious and fairly slow, which has led to thousands of manatees being injured or killed.
4.D At one point, there were only about 2,000 manatees left in Florida.But by 2016, there were roughly 8,800 manatees.
But now manatees are facing a new challenge：they can't get enough to eat.Many of the beds of sea grass that manatees depend upon have been killed by human-caused pollution.Sea grass began to disappear around 2011.Warming seas, combined with polluted water and fertilizers that have washed off of farmlands, have created huge growths of algae on the ocean's surface.
In 2021, about 1,100 manatees died from starving. 5.A Many of the manatees that remain are so thin that their ribs can be seen.Often they have trouble swimming.
So last December, wildlife experts came up with a plan to get emergency food to the manatees.They decided to feed them green vegetables like lettuce and cabbage.In the long term, Florida is working to help restore sea grass beds.But that will take time.
A．That was a record.
B．They can weigh up to 590 kilograms.
C．The feeding station has been very successful.
D．With protection, the number of manatees managed to increase.
E．It blocks the sunlight that allows the sea grass to grow.
F．But feeding these massive sea creatures takes a lot of food.
G．Research needs to be done to determine what food would be best.
语篇导读：本文是一篇说明文。介绍了海牛这种海洋动物，它们的特点以及习性等情况。
解析：
1．根据下文“So far, the rescue workers have already given out 25 tons of lettuce.”可知，提到了投喂海牛的莴苣，可见这些海洋生物需要的食物量很大。故F选项“但是喂养这些巨大的海洋生物需要大量的食物。”符合语境。故选F。
2．根据上文“Manatees are huge sea mammals that can be as long as 4 meters when grown.”可知，海牛是巨大的海洋哺乳动物，成年可以长到4米长。所以本段主要是在说明海牛的身体特点，上文提到了身长，推测空处应是在说明体重。故B选项“它们可以重达590千克。”符合语境。故选B。
3．根据上文可知，本句应具体说明人类船只是如何影响海牛的生存的：阻挡了让海草生长的阳光，故E选项“它阻挡了让海草生长的阳光。”符合语境。故选E。
4．根据下文可知，提到了海牛数量有所增加，说明保护措施起效了。故D选项“在保护下，海牛数量成功地增加了。”符合语境。故选D。
5．根据上文“In 2021, about 1,100 manatees died from starving.”可知，上文具体说明了死于饥饿的海牛数量，可知本句对此进行评价：那是一个记录。故A选项“那是一个记录。”符合语境。故选A。
