READ AND EXPLORE
Peple in Amsterdam have been enjying the benefits f cycling fr years. The idea began abut 50 years ag，and was first knwn as “white bikes”Amsterdam is a gd city fr cycling because it′s flat and therefre cnvenient fr bikes.
There are als plenty f places fr bicycle parking and mst streets in the city centre have a bicycle path. Because f its cnvenience fr bicycles, Amsterdam has becme very ppular with cyclists - an amazing 38% f all trips are made by bike. Sme peple even call Amsterdam “the City f Bicycles”.
Where did the idea f “white bikes” cme frm? In the 1960s， a grup f cycling fans came up with an idea. They believed that it wuld be better fr everybdy if cars weren′t allwed in the city centre and nly bicycles were. They were hpeful that this wuld help t save energy， reduce pllutin and prvide free public transprt. The grup painted hundreds f bicycles white and placed them in many areas arund Amsterdam fr peple t use.
Anyne was allwed t take them and use them fr shrt jurneys. Peple wuld leave the bike in the place where they finished their jurney，s that smene else culd then take it and use it frm there，Sn after，hwever， prblems came up and the “white bikes” all disappeared—thieves stle them all in a matter f weeks!
In 1999，the “white bikes” returned t Amsterdam - this time with a cmputer tracking system t recrd their every mve! T take a bicycle，yu had t put in a special card. The new “white bikes” were nt actually white but painted in bright clurs. The bikes were parked at special parking places. Thus peple wh wanted t use them had t take them t anther special parking place near their destinatin and leave them there.
Thanks t the ideas and effrts f many peple，like the cycling fans f the 1960s and thse wh enabled there turn f “white bikes”，yu can nw enjy clean air and easy transprt in central Amsterdam.
Nwadays，the idea f “white bikes”has pedalled its way arund the wrld and there has been a glbal increase in bike-sharing.
In China，mre and mre cities have their wn “white bike” prgrammes. Bth the lcals and turists like t use shared bikes because bike-sharing is a cheap and easy way t save energy，reduce air and nise pllutin，and enjy the benefits f exercise in cities. Hwever，prblems can als develp，like the theft f bikes and parking issues. Frtunately，peple are trying different ways f slving thse prblems. Where will bike-sharing g in China? Yu decide.
It′s flat and therefre cnvenient fr bicycles.

Develpment f “White Bikes”
Peple in Amsterdam first had the idea fr“white bikes”. They wanted t reduce the amunt f traffic and pllutin in the city centre. They painted hundreds f bikes white and left them arund the city centre fr peple t use. Within a matter f weeks，the bikes had all been stlen and the prject came t an end.
“White bikes” returned t Amsterdam. This time every bike had a cmputer tracking system in it t make it pssible t recrd its mvements and yu had t use a special card t take a bike.
Bike-sharing is becming mre and mre ppular in cities arund the wrld，including Chinese cities
1 Why did cycling fans put frward the idea f “white bikes” in the 1960s?2 What is the difference between the “white bikes” f the 1960s and f 1999?3 What effects have “white bikes” had n Amsterdam?4 Why has the idea spread t ther parts f the wrld in recent years?
1 What des the title “White Bikes′ n the Rad” mean?
The title refers t “white bikes”being used t ride arund the streets f a city. Apart frm the literal meaning，the title can als mean that the effrt t implement “white bikes”prjects takes time and itis still n the way. There′re still aspects that need t be imprved.
2 What des the writer mean by saying “Where will bike-sharing g in China? Yu decide.”?
Yung peple like the students will determine hw successful bike-sharing is in the future by deciding whether r nt and hw much they want t use it. It can als mean that whether r nt bike-sharing can exist successfully depends n each individual. Everyne has t take the respnsibility t take care f bike-sharing s that it can last lnger and help peple better.
