The study of animals is an important part of scientific ___. Scientists have been studying animals for a long time to learn more about them and to understand their behaviors. In the past, scientists would conduct ___ to observe animals in their natural habitats. However, with the development of technology, new ___ have been developed to study animals.
Nowadays, scientists use various methods to collect data about animals. One of the most common methods is to observe animals in the wild. By doing so, scientists can learn about the animals' natural behaviors and habits. In addition, scientists also use technology to study animals. For example, they use cameras and sensors to monitor animals' movements and activities.
The ___ of these studies have provided scientists with valuable ___ about animals. Through these studies, scientists have learned that animals have many ___ behaviors to humans. These similarities have led scientists to believe that animals may have some of the same cognitive abilities as humans.
Furthermore, the study of animals has also contributed to the development of medical ___ and treatments. Many diseases that affect humans can also affect animals. By studying animals, scientists have been able to develop new drugs and treatments that can be used to treat both humans and animals.
The study of animals is not only beneficial to science, but it is also important for the protection of wildlife. By learning more about animals, we can better understand their needs and how to protect them.
A. important
B. discovered
C. experiments
D. animals
E. scientists
F. results
G. research
H. knowledge
I. methods
J. similar
K. human
L. information
答案解析：
1.G. research：句意表示“動物的研究是科學(xué)研究的重要組成部分”，research意為“研究”，符合句意。
2.C. experiments：后文提到“科學(xué)家會在自然棲息地觀察動物”，這里應(yīng)該是提到過去科學(xué)家會做實(shí)驗(yàn)（experiments）來觀察動物。
3.I. methods：隨著技術(shù)的發(fā)展，科學(xué)家已經(jīng)開發(fā)出新的方法來研究動物，methods意為“方法”，符合句意。
4.F. results：句意表示“這些研究的結(jié)果為科學(xué)家提供了有關(guān)動物的寶貴信息”，results意為“結(jié)果”，符合句意。
5.L. information：后文提到科學(xué)家通過這些研究學(xué)到了很多，所以這里指的是他們獲得了關(guān)于動物的寶貴信息（information）。
6.J. similar：句意表示“通過這些研究，科學(xué)家發(fā)現(xiàn)動物有許多與人類相似的行為”，similar意為“相似的”，符合句意。
7.K. human：與前面的animals相對應(yīng)，這里指的是“人類的”，即animals have many similar behaviors to humans（動物有許多與人類相似的行為）。
8.H. knowledge：句意表示“動物的研究不僅有利于科學(xué)，而且對野生動物的保護(hù)也很重要”，knowledge意為“知識”，符合句意。這里指的是通過研究動物，我們獲得了更多關(guān)于它們的知識，從而可以更好地保護(hù)它們。
