Mr. Jones had a big tree in his garden， and the children had tied a long _7_ to one of the branches， so that they could swing on it.
Mr. Jones saw the professor _8_ when he saw the rope and looked carefully up and down the road. When he saw that there was _9_ in sight， he stepped into the garden (there was no fence)， put his umbrella， newspaper， bag and hat nearly on the grass and _10_ the rope. He pulled it _11_ to see whether it was strong enough to take his weight， then ran as fast as he could and swung into the _12_ on the end of the rope， his grey hair blowing all around _13_. _14_ he swung， sometimes taking a few more _15_ steps on the grass when the rope began to swing _16_ slowly for him.
_17_ the professor stopped， straightened his tie， combed his hair carefully， put on his hat， _18_ his umbrella， newspaper and bag， and continued _19_ his way to the university， looking as _20_ and correct and respectable as one would expect a professor to be.

A.because
B.as
C.so
D.for
