Fortunately it is（51） longer necessary that every lecture or every book about this subject has to start with the proof of this idea. At present it is（52） accepted, although more as a self-evident statement（53） on the basis of a closely-reasoned scientific proof. The recognition of the importance of greenspaces in the urban environment is the（54） step on the right way. this does not（55）, however, that sufficient details are known about the functions of greenspace in towns and about the way in which the inhabitants （居民） are using these spaces.

So it is obvious that recreation in the open（62） has to begin at the street-door of the house. The urban environment has to offer as many recreation activities as（63）, and the design of these has to be such that more obligatory （必须做的） activities can also have a recreative aspect. The very best standard of living is nothing if it is not possible to（64） a pleasant walk in the district, if the children cannot be allowed to play in the streets because the risks of traffic are too great, if during shopping you can nowhere（65） a spot for enjoying for a moment the nice weather, in short if you only feel yourself at home after the street-door of your house is closed after you. 51 A not B no C any D some 52 A generally B scarcely C rarely D seldom 53 A no B less C than D then 54 A one B second C third D first 55 A produce B utter C speak D mean 56 A district B region C area D scope 57 A lives B life C living D live 58 A lecture B opinion C talk D speech 59 A little B much C lot of D many 60 A reach B come C arrive D derive 61 A walking B running C activities D eating 62 A sky B house C home D air 63 A might B probable C could D possible 64 A make B take C bring D go 65 A look B seek C look for D find 答案 51.
