It is always hard for a small fish to live in a big pond. Pluto's recent departure from the classical planet family clearly proves that size really matters.

Astronomers voted on August 24 to create the first scientific definition of the word planet, and Pluto obviously didn't make the cut. It turned out to be only a "dwarf planet" (矮行星). After weeks of heated debate, over 2,500 astronomers from 73 countries voted on the definition of a "planet" at a conference of the international Astronomical Union (IAU). According to the definition, a planet must have a clear neighborhood around its orbit. Pluto has widely been considered a planet since its discovery in 1930. Unfortunately, it has a special orbit which overlaps with Neptune's. It is all because, compared with Neptune, Pluto is very small. It is attracted by Neptune's gravity when the two planets get closer.

According to IAU, a "dwarf planet" should have an orbit around the Sun. It will not have a clear neighborhood around its orbit, and must not be a satellite. The new classification means that the science textbooks will have to be updated. The solar system is now made up of the eight "classical planets," together with a number of dwarf planets. The classical planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The debate over Pluto's status started in 1992. After an advanced telescope was sent into space, astronomers started find a belt of objects, which lies beyond Neptune. The belt contains nearly 1,000 objects, including Pluto. As they continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system. There are at least two objects of a similar size to Pluto.

It seems that even if the IAU had kept Pluto's status as a planet, the classical theory of nine planets in the solar system would have had to be changed, but the other way around. More dwarf, planets of a similar size to Pluto would join the family of planets. Scientists will probably find many more dwarf planets.

1.According to the passage, Pluto is ________ .

2.The sentence "It is always hard for a small fish to live in a big pond" quoted in the beginning of the passage is used to ________.

3.From the last paragraph we can infer that if IAU kept Pluto's status as a planet, the number of planets in the solar system would be________.

4.Which of the following statements is NOT true aceording to the passage?

If you read the news about honeybee survival, it's all very confusing.

The Hoover Institution's Dr. Henry Miller notes “The reality is that honeybee populations are not declining. According to U.N. Food and Agriculture Organization(FAO) statistics,the world's honeybee population rose to 80 million colonies(群落) in 2011 from 50 million in1960.”Meanwhile Jennifer Sass of the Natural Resources Defense Council points out “The number of managed honeybee colonies in the U. S. has dropped from four million hives(蜂群) in 1970 to 2.5 million today.”

Surprisingly, both of these claims are correct. Miller points to the “global” commercial honeybee-hive count, which has grown considerably. Sass points to domestic colony numbers only, which have in fact declined.

Far more bees are farmed for making honey than for pollination(传粉) services. Since more honey is now made overseas than it was in the past, more hives are kept overseas, and fewer in the United States and Europe. And the global number of commercial hives and honey they produce has grown to meet the demands of an expanding world population. Such shifts offer no evidence of a honeybee hive crisis. They simply represent the market forces of supply and demand.

The FAO data also clarify that national or even regional declines in the size of the managed honeybee population cannot prove claims of a global pollinator decline or a pollination crisis. However, it emphasizes that solutions to those problems must be motivated locally, rather than globally.

Solutions will follow only if we take a non-subjective look at the issues, so we can address them appropriately rather than have a crisis mentality. As I highlight in a recent post for The Hill,a big part of the solution lies at the very local level: with the beekeepers, farmers, and communities that surround them.

1.What makes the news confusing?

A.Various species. B.Different affects.

C.Complicated statistics. D.Contradictory conclusions.

2.What contributes to the growth of commercial hives?

A.The claims of the FAO.

B.The shift of honey export.

C.The increasing demands of honey.

D.The more services of pollination.

3.What's the author's attitude to the honeybee population issue?

A.Supportive. B.Objective.

C.Confused. D.Doubtful.

4.What would be the best title for the text?

A.Honeybee Crisis Solved or Not?

B.Honeybee Population Declining or Not?

C.Honeybee Market Global or Local?

D.Honeybee Research Global or Local?
