My name is Wang Kun. Ever since middle school, my sister and I     1     (dream) about     2     (take) a great bike trip. When we graduated     3     college, we finally got the chance to do it. It was     4     (I) sister who first had the idea to cycle along the Mekong River from where it begins to     5     it ends. The Dai live near the Lancang River,     6     Chinese part of the river that is called the Mekong River in other     7     (country). Wang Wei soon got them     8     (interest) in cycling too. She insisted that we should find the source of the river. She gave me a determined look. Once she has made     9     her mind, nothing can change it.     10     (final), I had to give in.
