Found a “class” on YouTube and this was some of many sentences in the lesson.

Edit: To save a click to imgur they slides say (both in English and Spanish):

• “If you think education is expensive, wait till you see what ignorance costs you.”
• “The fact (that) nowadays fewer men smoke is a headache for the Chinese tobacco industry”
• “If you lend someone $20 and never see that person again, it was probably worth it”
• “The old cottage had only one bed, so we all took turns sleeping in it.”
