Mr.Jones woke early one morning，before the sun had risen.It was a beautiful morning，_31_ he went to the window and looked out.He was _32_ to see a neatly-dressed and mid-aged professor，who _33_ in the university just up the road from Mr.Jones‘house，coming the direction of the town.He had grey hair thick glasses，and was _34 an umbrella，a morning newspaper and a bag.Mr.Jones thought that he must have _35_ by the night train _36_ taking a taxi.
Mr.Jones had a big tree in his garden，and the children had tied a long _37_ to one of the branches，so that they could swing on it.
Mr.Jones saw the professor _38_ when he saw the rope and looked carefully up and down the road.When he saw that there was _39_ in sight，he stepped into the garden(there was no fence)，put his umbrella，newspaper，bag and hat nearly on the grass and _40_ the rope.He pulled it _41_ to see whether it was strong enough to take his weight，then ran as fast as he could and swung into the _42_ on the end of the rope，his grey hair blowing all around _43_._44_ he swung，sometimes taking a few more _45_ steps on the grass when the rope began to swing _46_ slowly for him.
_47_ the professor stopped，straightened his tie，combed his hair carefully，put on his hat，_48_ his umbrella，newspaper and bag，and continued _49_ his way to the university，looking as _50_ and correct and respectable as one would expect a professor to be.
