Over the last 100 years, many dinosaur egg fossils(化石)     1    (find), but finding one with a well-preserved embryo(胚胎) inside is extremely rare. A dinosaur embryo     2    (date) back to 66 million years ago was recently discovered in Ganzhou, Jiangxi Province. The    3    (perfect) preserved fossil is helping researchers understand the link between modern birds and their dinosaur ancestors.

The egg,     4    was named “Baby Yingliang”, is placed in the Yingliang Stone Nature History Museum in Fujian Province. The creature     5    (measure) 27 centimeters from head to tail, and it lies inside a 17-centimeter-long egg. Its position within the egg indicates that these dinosaurs developed     6    birdlike position close to hatching, according to the study published in the journal iScience in 2021. 

Paleontologists believe it belongs to a toothless dinosaur     7    (call) Oviraptor. They had varied beaks(喙) and body sizes,     8    they can adopt a wide range of diets. Team member Steve Brusatte from the University of Edinburgh, Scotland, told China Daily that this little dinosaur looks just like a baby bird in its egg, providing more evidence that many features of today’s birds first evolved in their ancestors.

Dinosaur embryos are some of the rarest fossils and most of them are incomplete with the bones dislocated. The embryo is preserved     9    great condition and helps us answer many questions about dinosaurs’     10    (grow).

The Honghe Hani Rice Terraces(梯田), in southern Yunnan, China, cover a huge 16, 603-hectare area. The terraces,     1    (know)to all of the world now, were made out of a thick forest by the Hani people. The terraces rise at different angles from a shallow 15°    2     a steep 75°, forming a wonderful landscape(景观)that     3    (be)rare in the world.

In 2003, the terraced fields were     4    (official)recognized by UNESCO as a World Cultural and Natural Heritage site. About 1,300 years ago, the Hani people first     5    (come)to the steep mountains. They struggled against the difficult terrain(地形), successfully creating the terraces, where they grew rice in order to make     6    (they) living. Over the past 1,300 years, the Hani people have developed a complex system of channels     7    (bring)water from the forested mountaintops. They show great appreciation for natural phenomena such as rivers, mountains, the sun, fire     8     the moon. They have also created a complete farming system     9     involves cattle, ducks, and fish and supports the     10    (produce)of red rice, the area's main crop.

The landscape changes through the year. In April the terraces are all green as rice starts to grow; in later parts of the year it is yellowish brown as the rice ripens. In February, the terraces become bare earth, with the water reflecting(反射)the sky.
