Keeping up with the Dinosaurs
Directions:
Read the dinosaur facts below. Then, write True or False in the blanks before the sentences
at the bottom of the page.
Paleontologists believe that the first true dinosaur evolved on Earth about 225 million years ago and became extinct or disappeared about 65 million years ago. All true dinosaurs were land-living creatures. The gigantic prehistoric sea creatures, such as ichthyosaurs, mosasaurs and plesiosaurs, were not really dinosaurs. Pterosaurs were not really dinosaurs either. They were flying reptiles that looked like lizards with wings.
The word dinosaur means “terrible lizard”, but dinosaurs were not lizards.
Modern science now links dinosaurs to birds. They are thought to be the closest relatives to the dinosaurs. Crocodiles are also thought to be more distant relatives of the dinosaurs. Scientists believe all animals and plants living on Earth today are descendants of creatures that lived when dinosaurs roamed the earth.
True or false?
1. The first dinosaur evolved on Earth
about 65 million years ago.
2. Ichthyosaurs were true dinosaurs.
3. Dinosaurs were not lizards.
4. Scientists believe birds are related to dinosaurs.
5. Some dinosaurs were flying reptiles.

译文：
恐龙追追追
指示：
阅读下列关于恐龙的论述。然后，判断本页下方句子的正误，并在句子前方写上True或False。
古生物学家认为第一只真正的恐龙出现在地球上的时间约为2.25亿年前，并在大约6,500万年前灭绝。所有真正的恐龙都是陆地生物。那些巨大的史前海洋生物，例如鱼龙、沧龙、蛇颈龙其实都不是真正的恐龙。翼龙也不是真正的恐龙，
它们是会飞的爬行动物，看上去像是长着翅膀的蜥蜴。
恐龙的意思为“可怕的蜥蜴”，但是恐龙并不是蜥蜴。现代科学把恐龙和鸟联系到一起，认为鸟类是恐龙的近亲，而鳄鱼则是恐龙的远亲。科学家们认为现在地球上所有的动植物都是恐龙时期生物的后代。
是非题：
1. 第一只恐龙出现在地球上的时间约为6,500万年前。
2. 鱼龙是真正的恐龙。
3. 恐龙不是蜥蜴。
4. 科学家认为鸟类与恐龙有关系。
5. 有些恐龙是会飞的爬行动物。
