"She likes to run for half an hour every day."
I'd learn more and faster if I could play the audio of this correct answer. Hearing it aloud would help me figure out what I got wrong more easily. Maybe it's me, and I simply haven't figured out how to play the audio for right answers? If so, please advise. Many thanks!
it would help if they would put hints over the answers as well, to see what each word means
Why is duolingo splitting the verbs "跑步" and ”游泳“ in half?
Also, is it grammatically correct to say something like "我每天喜欢游泳" to mean "I like swimming every day"?
These are separable verbs (also called verb object phrases). You can typically identify them when the first character indicates an action and the second character indicates a noun. For example in 跑步, 跑 is actually the verb "to run" while 步 is a noun meaning "a step" as in a step in a process.
Modifiers should come after the verb word, and therefore are usually placed between the two characters that make up a separable word. These modifiers are typically auxiliary words like “着 (zhe), 了(le), 过(guò) and quantifiers as we see in this case with the quantifier “半个小时".
It is correct to say 我每天喜欢游泳 since there are no modifiers in your sentence. However if you wanted to say I swam for an hour then 我游了一个小时泳 would be correct. Note the verb modifiers come after the verb word which in this case is 游.
