1We arrived at the city library before it opened.
2A short line of students was waiting outside.
3We found two free desks on the second floor.
4I started by reading my history lecture notes.
5My friend worked on her science project nearby.
6The library was completely silent all morning.
7I borrowed three books about the industrial revolution.
8The librarian helped me find them very quickly.
9At noon we ate sandwiches in the small café.
10We were not allowed to bring drinks upstairs.
11In the afternoon I printed my essay draft.
12The printer broke, so we waited fifteen minutes.
13A kind assistant fixed it and apologized politely.
14I corrected my essay and checked the references.
15My friend memorized twenty new science terms.
16We tested each other during a short break.
17By five o'clock we both felt quite tired.
18Still, we had finished everything on our list.
19We returned the books before leaving the building.
20It was a long but very productive Saturday.
