How was that________—writing correct sentences after getting so little input(投入)？My e-mail included very simple sentences．________the most important thing was my research：I looked for example________on the Web and in dictionaries．
I________a lot of time on each sentence．It took me more than an hour to write my first e-mail，which included only a few German sentences．
