It was the final part of the 2016 World Triathlon series in Mexico. Jonny was     1     when he was about to fall onto the track.     2     his brother’s timely help, he got second place at last. Alistair chose brotherly love rather than the chance to win the race. They were brothers     3    . Throughout their entire life, the brothers always     4     each other for help when they were in trouble, and their mother     5     them.

It was wonderful to hear from you. I know you are     1     (die) to know my life in PNG .The classrooms are made of bamboo and the    2     (roof) of grass .Many of the boys have worked a long way, sometimes up to two hours to get to school .Students have no concept of doing experiments and there is    3     equipment, either .Sometimes I wonder how relevant chemistry    4     (be) to these students, most of     5     will be going back to their villages after Year 8.

I    6     (visit) a remote village. The huts there were round    7     there were no windows .So it took time for my eyes    8     (adjust) to the darkness inside .I could not participate in the conversation,for I couldn't speak much of the local English dialect . It was    9     a privilege to have spent a day with Tombe’s family .

I    10     (real) enjoy the work as a volunteer teacher in PNG.
