　　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.
