Goodbye Pluto
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．
1
After weeks of heated debate, over 2, 500 astronomers from 75 countries voted on the definition of a “planet” at a conference of the International Astronomical Union(IAU)． 2 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． 3 ．
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 to find a belt of objects, which lies beyond Neptune．The belt contains nearly 1, 000 objects, including Pluto． 4 There are at least two objects of a similar size to Pluto．
5 More dwarf planets of a similar size to Pluto would join the family of planets．Scientists will probably find many more dwarf planets．
A．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．
B．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”．
C．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．
D．Pluto will be cut away for ever．
E．As they continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system．
F．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．
G．Spaceships will be sent onto Pluto．

Freezing can keep food fresh and safe to eat. Freezing lowers the food temperature below zero degree Celsius. That is the point where water turns to ice. , it is important to lower the temperature to between minus fifteen and minus twenty degrees Celsius as quickly as possible. The faster the freezing process is, the fresher the taste of the food.
Fruits and vegetables can be spread out inside the freezer. Once the food is frozen, . Fruits are usually not cooked before they are frozen. This allows them to keep their fresh taste. The simplest way to prepare fruits is to cut them up and place them in a container inside the freeze before putting it in the container. This will keep it from sticking to the container. This is called the “dry pack” method.
, The fruit is prepared along with some of its liquid or juice. You can ad some sugar to fruits that are naturally juicy. The sugar sweetens the fruit and brings out its natural juices.
. Blanching means placing the vegetables in boiling water for a few minutes and then quickly placing them into very cold water. Blanching slows down the natural chemical aging process. All extra water should be removed before placing the vegetables into containers and freezing. .
A. it should be placed in containers and then stored at a temperature of about minus twenty degrees Celsius
B. Vegetables are either cooked or blanched before freezing
C. To start the freezing process
D. To keep them fresh for a long time
E. The second way is the “wet pack” method
F. Most foods can be stored frozen for up to one year
