The theoretical separation of living， working， traffic and recreation which for many years has been used in town-and-country planning， has in my opinion resulted in disproportionate attention for forms of recreation far from home， whereas there was relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home…… We have come to the conclusion that this is not right， because an important part of the time which we do not pass in sleeping or working， is used for activities at and around home. So it is obvious that recreation in the open air has to begin at the street-door of the house .The urban environment has to offer as many recreation activities as possible， and the design of these has to be such that more obligatory activities can also have a recreative aspect.
The very best standard of living is nothing if it is not possible to take 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 find 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.

Passage 3
There are desert plants which survive the dry season in the form of inactive seeds. There are also desert insects which survive as inactive larvae（幼虫）。 In addition， difficult as it is to believe， there are desert fish which can survive through years of drought（干旱）in the form of inactive eggs. These are the shrimps（小虾）that live in the Mojave Desert， an intensely dry region in the south-west of the United States where shade temperatures of over 50.C are often recorded.
The eggs of the Mojave shrimps are the size and have the appearance of grains of sand. When sufficient spring rain falls to form a lake ， once every two to five years， these eggs hatch（孵化）。 Then the water is soon filled with millions of tiny shrimps about a millimeter long which feed on tiny plant and animal organisms which also grow in the temporary desert lake. Within a week， the shrimps grow from their original 1 millimetre to a length of about 1.5 centimetres.
Throughout the time that the shrimps are rapidly maturing， the water in the lake equally rapidly evaporates. Therefore， for the shrimps it is a race against time. By the twelfth day， however， when they are about 3 centimetre long， hundreds of tiny eggs form on the underbodies of the females. Usually this time， all that remains of the lake is a large， muddy patch of wet soil. On the thirteenth day and the next， during the final hours of their brief lives， the shrimps lay their eggs in the mud. Then ， having ensured that their species will survive， the shrimps die as the last of the water evaporates.
