0 Congratulations on winning of the tennis championship! You must be

4 all those hours for every day, but it is worth it in the end, isn’t it?

5 Perhaps you are thinking of going on holiday so that you can have

6 a break from tennis and reỉax. Can you tell me exactly what is kind of

7 tennis racquet you chose for the competition? If I would get the same,

8 it might help me to improve my game. Anyway, congratulations on

9 your great victory! I’m still studying English every single day and the

10 course has three months to go.  I have moved house, as if you can see

11 from my new address. Make sure you reply back to the right address!

12 Your last letter went to my old address, but it wasn’t by your fault

13 because I hadn’t told anyone which I had moved then. Did you know that

14 I have had a job for the last three weeks? I work in a restaurant four

15 evenings a week. I like it, but I don’t arrive to home until one o’clock in the morning, which is a bit inconvenient.

On the provincial level, some women in Canada could vote beginning in 1916. Suffrage expanded to the federal level over the next few years: In 1917 nurses and women in the armed forces could vote, then women whose fathers, husbands, or sons were serving overseas. In 1918 legislation passed expanding suffrage to female citizens excluding Asian-Canadian women and First Nation women, who did not win the right to vote until the 1940s and 1960s, respectively.

Non-indigenous women in Australia got the right to vote beginning in 1895, when the state of South Australia passed colony- and state-wide suffrage, in addition to the right to stand for parliament. In 1899, state suffrage expanded to Western Australia. In 1902, non-indigenous women won the right to vote on the federal level with the passing of the Commonwealth Franchise Act. Indigenous Australians didn't get the federal right to vote until 1962.
