Step 3 While-reading Activity 3 Reading comprehension of the text 1. Look at the title and skim the text. Decide what type of essay it is. Strategy of identifying text type: A title usually covers the main point of the subject or keywords of the essay. It shares the theme of the essay and tells the reader what to expect. There are the four major types of essay: narrative, descriptive, expository, and argumentative. A narrative essay is a story with a beginning, middle, and end. A descriptive essay describes a subject and lists interesting details. An expository essay is factual, giving information on a subject. An argumentative essay aims to convince the reader. This essay is an expository essay. 2. Read the text again. Summarize the main idea of each paragraph. Para.1 Travel from east to west began long before Columbus. Para.2 In ancient times, travel east to west was on the Silk Road. Para.3 Zheng He’s sea voyages built relations with other countries. Para.4 The 21st Century Maritime Silk Road has encouraged cooperation and strengthened the bonds between China and the rest of the world (Today, the Belt and Road Initiative is picking up where Zheng He left off.)
