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. Read the dialogue and pay attention to the expressions in red.
S1: Wow! Look at the library! What a cool building!
S2: Yes. I've never seen a building like this before.
How well they designed it! Let's go inside and explore.
S1: Check out those bookshelves! How tall they are! They go all the way up to the ceiling! Come on, let's have a look at the exhibition.
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!
