内容简介

Clues from the past History is the study of people, places and events from the past. We study history to learn about the past. Experts, such as historians and archaeologists, help us understand the past. To learn about life from long ago, they examine clues and records from people in the past. How do they do this? Historians use both primary sources and secondary sources. A primary source is material written at the time an event happened. It is often written by a person who was an eyewitness to the event. Primary sources can be books, diaries, reports, official documents and photographs. A secondary source is material written based on primary sources. Some historians also study oral history. This is a collection of stories that are told and passed down from one generation to the next. What happens when there is no record or written history left behind? That is where archaeologists are needed. They examine artifacts. These are man-made objects used by past civilizations. Historical artifacts include tools, pottery, clothes, jewelry and even paintings. Archaeologists also study human remains, such as bones and hair. There are many ruins of ancient buildings for them to study as well. All of these contribute to archaeologists learning how people lived in the past. Many historians often make timelines to list events in history. Timelines show the dates that various events occurred and let historians see the order of past events. On many timelines, there are sometimes the abbreviations B.C. and A.D. after dates. B.C. stands for “before Christ”. A.D. stands for “anno Domini ”. That is Latin for “years after the birth of Christ”. Nowadays, historians h**e access to many modern technologies. This makes studying the past much easier. Many primary sources h**e been translated and pu**ished in books or on CD-ROMs. Other books, such as encyclopedias, almanacs and atlases provide much information, too. Studying the past has never been easier than today. 《跟着美国课本学英文阅读2》编辑**： ◆本书精选美国课堂教材，内容广泛，涉及历史、人文、科学等多个方面，让学习者深入了解各类趣味知识，扩展知识面！ ◆每篇阅读材料前后都有相应阅读训练，帮助学习者快速掌握阅读重点，*加关注文章主旨以及重要细节，熟悉考试答题节奏！ ◆每篇文章都配有与主题相关的图片，使学习者对主题和关键观点有*直观的理解。边看图边学百科知识，让阅读*加轻松有趣！
