I'd like to welcome Dr White to our series of lectures on Biology. This is the most popular lecture we have had all year. Thank you. Today I'd like to talk about sea animals. We all know the sea occupies a greater area of the Earth's surface than the land. It is the home of millions of living. Animals and plants of the sea have various shapes, colours and sizes. Do you know that there is more life in the sea than on land? The animals and plants of the sea are very important to Man as a source of food. Sea animals such as lobsters, crabs, fish and many shellfish can be eaten. Some se aplants, like seaweed, are also used as food. Animals in the sea range from tiny one-celled animals to huge mammals. The most well-known of all sea animals are the fish. The majority of fish live in the shallow parts of the sea.
我誠心歡迎維特博士參加我們的生物系列講座。這是我們一整年最受歡迎的講座。 謝謝，今天，我想講講海洋生物。我們知道海洋在地球上占了很大的地域，比陸地更多。海洋是十萬生物居住的地方。海洋的動物和植物有著不同種類的形狀，顏色和大小。你知道海洋的生物比陸地生物更多嗎？ 海洋動物和植物對人類非常重要，就像食物的來源一樣。海洋動物像龍蝦，螃蟹，魚和很多貝類都能吃。一些海洋植物，像海藻也經(jīng)常作為食物。 海洋動物的種類很廣泛，從單細(xì)胞動物到巨大的哺乳類動物。最熟知的海洋動物是魚。很多魚居住在海洋的淺水區(qū)域。 ——By lsy34
