THE TIME MACHIN
I
am Professor Huang and I have just invented a time machine that allows
people to travel into the past or the future for five hours.
I thought that it would be fun to see what my father was like when he was 10 years old.
I packed a small bag and got into my time machine. I keyed in the words,
"1964, 11 Niven Road, Singapore" then pressed the button. There was a
"whoosh" and a "bang" ... the time machine was shaking and spinning and
in a moment, I was in front of the pre-war house, 11 Niven Road.
I saw four children looking for a lost dog. I recognised them ... they
were my father, my uncle Kelvin, my auntie Peek and auntie Janet. I
introduced myself as an old friend and agreed to help them look for
their lost dog, Blackie.
The children wanted to climb a hill and looked into the houses below. By
the time we reached the top, we were tired and decided to sit down and
rest. Suddenly I heard a dog barking. "Blackie!" my father shouted. We
traced the source of the barking to one of the houses. We looked down
and saw a dog chained to a pole. It was Blackie and he looked
frightened.
The children boldly knocked on the door of the house and demanded that
the man (who came to the door) return Blackie to them. The man asked the
children to prove the black dog was Blackie. My father called out
Blackie's name and the dog responded with an enthusiastic woa woa. The
man reluctantly gave Blackie back to the children.
We went back to 11 Niven Road and I bid them goodbye. My five hours were
almost up. I ran to a dark alley and in a flash I was gone. I found
myself back in my time. What an adventure!

CUNOSTINTE/PLANETE
Planetele
sunt cele mai mari obiecte exceptand Soarele. Spre deosebire de Soare,
planetele nu produc energia lor proprie, in schimb planetele reflecta
caldura si lumina vizibila produsa de Soare. Planetele Jupiter si Saturn
emit radiatii radio, undele radio, emise de Jupiter sunt asa puternice
incat pot fi receptionate pe pamant cu radiotelescoape. Cele patru planete
de langa Soare: Mercur, Venus, Pamant si Marte se numesc planete terestriale,
ele par sa contina fier si roci. Planetele terestriale si Pluto sunt cele
mai mici planete. Pamantul are un satelit, Marte are doi si Pluto are
unul. Mercur si Venus nu au sateliti.
Distantele dintre planete se masoara in unitati astronomice.
Cele mai mari planete, Jupiter, Saturn, Uranus si Neptun sunt numite planete gigant. In comparatie cu planetele terestriale ele contin fier usor si roci. Fiecare din planetele gigant au cateva sateliti. De asemenea ele au inele in jurul lor. Doar inelul luminos al planetei Saturn poate fi usor vazut cu un telescop mic. Toate planetele sunt inconjurate de variate tipuri de gaze. Gazele care inconjoara o planeta se numesc atmosfera. Pamantul este singura planeta care are destul oxigen in jurul sau si destula apa pe suprafata sa pentru a mentine viata.
