For the last couple of weeks, I had been stuck in front of my computer working on a project that was very important to me. My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but to no avail. It was only when I turned to meditation(沉思)for a solution that the answer came to me: turn to nature!
The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing, "I'm singing in the rain", a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we restrain(限制) our own spirits, which only leads to depression and stress.
Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city centre.
If you feel a little low in spirit and know that you have spent too much time indoors, relax completely, remove your shoes and let your inner child come out and play.
【小題1】The author felt depressed because she __________.

A.couldn't consume her waking hour
B.had not seen a film for a long time.
C.had not finished her work on time
D.had worked on a hard job for too long
【小題2】The author walked in a nature reserve in the rain in order to__________.
A.take photosB.find a solution to the project
C.hop along the pathD.cheer herself up
【小題3】The underlined part "to no avail" in Paragraph 1 probably means " __________.".
A.unsuccessfulB.unrelatedC.uninterestingD.unexpected
【小題4】In the author's opinion, __________.
A.a bath can make people relaxed
B.depression is usually caused by hard work
C.walking in a busy city centre harms people's health
D.adults should express their inner feelings freely
【小題5】The last paragraph mainly serves as a(n) __________.
A.explanationB.suggestionC.introductionD.reminder
