[单项选择]Young people are moving to cities at a faster rate than the rest of the population, according to a new Survey. It also shows the employment rate of young people is declining.
The Contemporary China Youth Population Development Studies Report was released last November by the China Teenagers Research Center and China’s Population Development Studies Center at Renmin University. The report shows that, although urban birthrates are declining, the percentage of young Chinese living in cities and towns is rising faster than that of the rest of the population. This is a result of migration from the countryside to the cities.
Lu Yilin, Dean of the Department of Youth Work at Beijing Youth Politics College says the cities can draw on fresh blood for future growth; the youth have a better chance to develop themselves and be in touch with new ideas. However there are also hidden difficulties. According to Lu, the urban youth who don’t have a registered permanent residence might f

Learn About Noble Gases（惰性气体）
1 Have you ever ridden on a balloon?Many tourist spots offer balloon rides in order for people to see
the beauty of a place from above.A balloon contains a noble gas called helium（氦）.Formerly,balloons con-
tamned hydrogen but hydrogen is very flammable and dangerous when uncontrolled.Therefore,people shifted
to helium,which is safer. Helium is safe because it has the properties of the noble gases.
2 People once believed that noble gases couldn't chemically react at all.For this reason,they were
called inert gases(隋性气体）.They were also listed under Group 0 in the old periodic table because scien-
tists believed that the gases have zero valence（价）electrons in their outer shell.This was later proven to be
untrue when some noble gas compounds were discovered.
3 The gases are elements,which share similar properties.These properties include being monoatomic,
colorless,odorless,being able to conduct electricity,and having low chemical reactivity.Noble gases
include helium,neon,argon,krypton,xenon and radon.These are all found in Group 18,in the right most
column of the periodic table.If you look at the periodic table,you will notice that these elements are the only
ones which do not have a charge. Helium has the lowest molecular（分子的）weight while radon is the
heaviest.
4 Remember that chemical reactions occur because atoms have valence electrons,which are electrons
in their outer shell.When the outer shell is"unfilled"or the required number of electrons is not yet com-
plete,the atom is more reactive.Noble gases have a full outer shell,meaning that they have complete elec-
trons in their outer shell.This complete number varies.For instance,the outer shell of helium has 2 valence
electrons while the outer shell of xenon has 8 electrons.Nowadays,there remains to be a few noble gases
because of the low chemical reactivity of these said gases.
5 because of their properties,noble gases have many important applications.They are widely used in
medicine and industries. For instance , liquid helium is used for superconducting magnets（磁体）.These
magnets are very important in physics and medicine.When a doctor suspects that a person's brain has been
damaged,he might request for Magnetic Resonance Imaging(MRI).MRI allows the doctor to"see"the
brain,without operating on the patient.
