One of the best-preserved fossils (化石) yet discovered has revealed that the young dinosaur used the same technique as baby birds     1     (break)out of its shell. The fossil, named Baby Yingliang, was found in southeast China and     2     (belong)to a group of feathered dinosaurs.

The creature is folded over, with its head resting between its legs and its arms pressed     6     either side of its neck.

In modern birds such postures are critical for     7     (success)hatching. The researchers now propose that this behaviour, which had been considered unique to birds, appeared in some dinosaurs,       8     (possible)hundreds of millions of years ago. Fion Waisum, one of the lead authors of the study, said, “It is interesting to see that this dinosaur baby     9     a chicken one pose in a similar way inside the egg, indicating similar pre-hatching     10     (behaviour).”

As the largest rainforest, the Amazon rainforest plays a significant role     1     maintaining the fine balance of the Earth’s ecosystem. The Amazon River, from     2     the rainforest gets its name, is close to 6, 400 kilometres in       3     (long) — roughly 100 kilometres longer than the Yangtze River. The forest’s different     4     (level) provide food and shelter for an unbelievable     5     (vary) of wildlife. More     6     1, 300 species of birds and over 400 species of mammals hide among the Amazon rainforest’s plant life. The Amazon rainforest is a treasure house of species     7     can be used for food or medicine. Over the past 50 years, about 17 percent of the rainforest     8     (disappear) due to human activities. As the impact of human activities continues to grow and the list of species in danger of     9     (extinct) becomes longer, we are     10     (leave) with a question: can we afford to damage the “lungs of the planet” ?
