The first zoo     1     (establish) around 3, 500 years ago by an Egyptian queen for her personal enjoyment. Five hundred years later, a Chinese emperor     2     (build) a huge zoo to show his power and wealth. Later zoos were set up for the purpose of studying animals.

Some of the early European zoos     3     (consist) of dark holes or dirty cages, the bad conditions of which made people disgusted. Later the zoos     4     (replace) by research centers and animals there were studied and     5     (keep) in good condition. These places became the first modern zoos. As early as the 1940s, scientists     6     (understand) that many kinds of wild animals faced extinction. Since then, zoos     7     (try) to save many endangered species, but relying on zoos     8     (save) species is not enough. The best method of protection is to leave them in their natural habitat.

Today, animals in large and natural reserves are fed a balanced diet and     9     (watch) carefully for any signs of disease. With specially trained keepers looking after them and some hospitals where they can be treated when ill, all the animals there live a comfortable life. Anyway, it is true that zoo breeding programs     10     (play) an important role in protecting many species of wildlife now.

Though many foreign experts said Japan’s water discharge would have a slight impact     1     the environment and human health, China     2     (ban) seafood from Japan in response to it. Ministry of Commerce spokesperson Shu Jueting called the discharge “    3     (extreme) selfish and irresponsible” and said it would cause damage and harm to the     4     (globe) marine environment,     5     cannot be predicted. North Korea’s Foreign Ministry called the release     6     “crime against humanity” and said Japan would be entirely responsible for its consequences.

In South Korea, fierce domestic political     7     (argue) has erupted because of its own government’s approval    8     the Japanese plan. Liberal critics accused the conservative government     9     (lead) by President Yoon Suk Yeol of improving ties with Japan at the sacrifice of public health. Surveys of South Koreans show that more than 80% of respondents oppose the Japanese discharge     10     more than 60% said they won’t eat seafood after the water release begins.

People release balloons for special occasions like memorial services and grand openings. It is fun and exciting. But it really causes great destruction to the environment and threatens the     1    (life) of our wildlife.

When a balloon     2    (fly) into the sky, it doesn’t end up    3    (stay) there. It eventually bursts and returns to the earth as ugly litter. Balloons can even travel thousands of miles and pollute the most remote and pure places. More     4    (sad), they can present a threat to many animals. Birds, whales, turtles and other animals often mistake balloons     5     food, which can do damage to them because balloons contain     6    (harm) chemicals. Balloons even kill animals. When an animal swallows a balloon, it can block its intestinal tract(肠道), resulting in starvation.

Part of the reason why releasing balloons     7    (forbid) in so few places is that some balloons do break down eventually. However, it takes about four years     8    (break) down completely.

Watching hundreds of balloons slowly going up into the sky might give you a five-second thrill,     9     is it worth a bunch of dead animals and so many places full of rubbish? Absolutely not.     10     we should do is to get creative and come up with alternative ways to celebrate.
