Compare the descriptions of the role models Which sentences show stronger feelings? Zhang Guimei worked tirelessly. How tirelessly Zhang Guimei worked! When we want to express feelings or emphasize certain things, we use exclamations（感叹句）. Two students are visiting the Qian Xuesen Library & Museum.

S2: Oh, look over there: that's China's first satellite. What an amazing collection they have in this museum! Tip: Pay attention to the differences between the exclamations with “what” and “how”. What a coocl building it is! What an amazing collection! What smart engineers they are! What bad weather it is! How well they designed it! How tall they are! We often begin an exclamation with the word _____ or _____. We can also use a word or phrase as an exclamation, such as Wow!
