[单选题]Text l Cycling in London is less pleasant than in many European cities.Main roads teem with lorries;winding back streets are hard Lo navigate.The number of bicycle journeys has nonetheless doubled since 2000.Nationally,just 2qo pedal to work.In Hackney,in London's East End,fully 9%do.But only 2%of women cycle to work in London,compared with 5%of men.Blacks and other ethnic minorities are reluctant to do it,too.Bori6 Johnson,London's mayor,oversaw the introduction of a bike-hiring scheme,which was started by his predecessor but quickly became known as the"Boris bike".He pushed for bright blue cycle paths on some busy roads.But the new cycle highways are far more ambitious and permanent.One will run east-west through the City and the West End.Another will run two miles from Elephant and Castle in the south to Farringdon in north London.Four existinE;routes will also be improved,while around 30 0f the city's busiest junctions wiU be made a bit less dangerous.The new superhighways ought io be much safer than London's existing cycle lanes.A raised pavement will keep cyclists away from cars and lorries.Junctions will be redesigned and some parking bays-including a rew for the disabled-will be removed.Cars will be prevented from turning down certain streets.Similar schemes exist elsewhere:since 2007 around 30 miles of protected cycle lanes have been created in New York.In Amsterdam,where lanes have existed for decades,old people and women are far more inclined to cycle.Greens have long lobbied for cycle paths on the grounds that movin8 people out of cars cuts air poUution.A series of highly publicised accidents,including one involving a newspaper journalist,and several deaths in the city have also put pressure on the mayor to make London safer.And the social transformation of the capital has encouraged officials to smile on cyclists.The population of inner London is rebounding as affluenL folk move in.The new inhabitants want cleaner streets and fewer cars,which are viewed as suburban.Cycling was once a means of transport for the poor.But it has become an imporlant marker of an affluent world city,argues Isabel Dedring,the deputy mayor for transport."There's more pressure on cities to be nice places to live,"she says.

Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate.A black
hole in the universe is not a solid object,like a planet,but it is shaped like a sphere（球体）.
Astronomers（天文学家）think that at the center of a black hole there is a single point in
space with infinite（无限的）density（稠密）.This single point is called a singularity（奇点）.
If the singularity theory is correct,it means that when a massive star collapses,all the
material in it disappears into the singularity.The center of a black hole would not really be a
hole at all,but an infinitely dense point.Anything that crosses the black hole is pulled in by
its great gravity.
Although black holes do exist,they are difficult to observe.These are the reasons.
No light or anything else comes out of black holes.As a result,they are invisible to
a telescope.
In astronomical terms,black holes are truly tiny.For example,a black hole formed
by the collapse of a giant star would have an event horizon（视界）only 18 miles across.
The nearest black holes would be dozens of light years away from Earth.One light
year is about 6 trillion（万亿）miles. Even the most powerlul telescopes could not pick out
an object so small at such a great distance.
In 1994 the Hubble Space Telescope provided evidence that black holes exist.There
are still answers to be found,however,so black holes remain one of the mysteries of the
universe.
Black holes exist but are difficult to observe.
A.Right
B.Wrong
C.Not mentioned
