Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.

But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.

Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.

“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”

     Nowadays, being a teacher is a difficult yet rewarding job. Not everyone is suited for teaching. Aside

from having love for working with children, teaching is a career like no other.

    An effective teacher is not only the master of his/her subject area, but also an educator with the strong

emotional backbone. Daily, the teacher communicates with students from different backgrounds, with

different learning skills, and with different emotions.

    The teacher will set high expectations of all students and never give up the underachievers. The teacher will always be available to students whether it's before classes begin or after school. He/She will also have additional work for students need extra assistance in learning the subject.

    An effective teacher will contrast his/her lesson with the material so that students will look at the

material in various ways. This will ensure that students remain on task during the entire class session.

Being asked openended questions, students will remain interested and not be bored. Difficult as this may

sound, it can be achieved.

    The teacher will always be an enthusiastic, organized, and caring individual, and will make learning fun. He/She will not simply write the assignment on the board，and tell students "There's your assignment.

Get to work!"  and proceed to sit at his/her desk for the remainder of the period. Instead, the teacher will

add games or use media in the learning process; in this way, students will crave (渴望) learning.

    Our children need support, guidance and proper instruction so that they will succeed in life, not only in

the career they choose, but also as the person they become.
