striking appearance. The moon may be divided into two major terrains: the maria (dark
lowlands) and the terrace( bright highlands). The contrast in the reflectivity (the capability
of reflecting light) of these two terrains suggested to many early observers that the two
(5) terrains might have different compositions, and this supposition was confirmed by missions to
the Moon such as Surveyor and Apollo. One of the most obvious differences
between the terrains is the smoothness of the maria in contrast to the roughness of the
highlands. This roughness is mostly caused by the abundance of craters; the highlands are
completely covered by large craters(greater than 40-50 km in diameter), while the craters
(10) of the maria tend to be much smaller. It is now known that the vast majority of the Moon's
craters were formed by the impact of solid bodies with the lunar surface.
Most of the near side of the Moon was thoroughly mapped and studied from telescopic
pictures years before the age of space exploration. Earth-based telescopes can resolve
objects as small as a few hundred meters on the lunar surface. Close observation of
(15) craters, combined with the way the Moon diffusely reflects sunlight, led to the
understanding that the Moon is covered by a surface layer, or regolith, that overlies the
solid rock of the Moon. Telescopic images permitted the cataloging of a bewildering array
of land forms. Craters were studied for clues to their origin; the large circular maria were
(20) seen. Strange, sinuous features were observed in the maria. Although various land forms
were catalogued, the majority of astronomers' attention was fixed on craters and their
origins.
Astronomers have known for a fairly long time that the shape of craters changes as
they increase in size. Small craters with diameters of less than 10-15 km have relatively
(25) simple shapes. They have rim crests that are elevated above the surrounding terrain,
smooth, bowl-shaped interiors, and depths that are about one-fifth to one-sixth their diameters.
The complexity of shape increases for larger craters.
What does the passage mainly discuss?
A.What astronomers learned from the Surveyor and Apollo space missions
B.Characteristics of the major terrains of the Moon
C.The origin of the Moon's craters
D.Techniques used to catalogue the Moon's land forms

It is reported that China uses 20 million trees each year to feed the country"sdisposable chopstick habit. At about 4,000 chopsticks per tree, that"s roughly 80 billionchopsticks per year——far more than the 57 billion(1)by the country"s national forestbureau.
While this is hardly the first time that the chopstick issue has come up in China, thenew numbers make the problem look particularly(2). The country"s last forest survey,published in 2009, documented rampant ( 猖獗的 ) deforestation and forest quality farbelow the global(3). Greenpeace has even dedicated a campaign to the chopstickproblem,(4)it for the destruction of 1.18 million square meters of forest every year.
China has tried to clamp down on chopsticks before—— (5) by taxing them andwooden floor boards, another environmental offender. In 2008, the Wall Street Journal"sJane Spencer reported on a cultural backlash against the chopsticks, led by celebrities,activists and6minded youth.
"Disposable chopsticks are(7)China"s forests," a 26-year-old activist, dressedas an orangutan ( 猩猩 ) reportedly said at a protest at Microsoft"s Chinese (8). "Wemust protest this pointless waste!"
But protest does not appear to have done the trick. In 2010, a(9)mudslide ( 泥石流 ) that killed 700 was blamed on deforestation, reports the Wall Street Journal. Perhapsthe activist"s appeal to the government represents an appeal to more transparently confrontthe issue.
"We must change our (10) habits and encourage people to carry their owntableware," he said.
