The three men built a small boat and set sail. All of a sudden, two dinosaurs rose to the surface and began to fight each other. The small boat was almost     1    by the dinosaurs before they were able to get away

They sailed to shore and explored the forest. They came across huge insects and many strange creatures. As they were     2     around, they noticed a man sitting    3    a tree in the distance-he was at least four meters tall. The men became afraid, and ran back to the boat.

They set sail again, and saw what looked like an exit, but it was    4    by rocks which had fallen down from the ceiling. They made a bomb to blow up the rocks. After the bomb exploded, their boat rushed     5    forward into a large hole. The boat floated down with the water. It was too fast for them to escape, They could only hold on to the boat in terror.

Old French made other    1    to Middle English as well. In old English Germanic way of making words plural was used. For example, they said housen instead of houses, and shoen instead of shoes. After the Normans took    2    they began using the French way of making plurals, adding an-s to house and shoe.

Over time I have been changed quite a lot. I began as a     1     machine in France in 1642. Although I was young I could     2     difficult sums. I developed very slowly and it     3     nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was     4     by an operator who used cards with holes, I could “think”

    5     and produce an answer quicker than any person. At that time it was     6     a technological revolution and the start of my “    7     intelligence”.

Dinosaurs did out suddenly about 65 million years ago. Some scientists think it came after an unexpected     1     when a huge rock from space     2     the earth and put too much dust into the air.     3     think the earth got too hot for the dinosaurs to live on any more.

Along with these physical changes, there come many psychological changes. Boys and girls tend to be different in this     1    . Many boys become risk-takers—they want to find their own limits and the limits of the world around them, but may not have the     2     to make good     3     in their behavior.

7 . However, the     1     of scientists towards this rise are completely different. On the one hand, Dr Foster thinks that any     2     in which the temperature increases     3     5 degrees would lead to a catastrophe. She says, “We can’t predict the climate well enough to know     4     to expect, but it could be very serious.” Others who agree with her think there may be     5     rise of several metres in the sea level, or predict severe storms, floods, droughts, famines, the     6     of diseases and the disappearances of     7    . On the other hand, there are those, like George Hambley, who are     8     to this view and believe that we should not worry about high levels of carbon dioxide in the air. They predict that any warming will be mild with few bad environmental       9    . In fact, Hambley states, “More carbon dioxide is actually a positive thing. It will make plants grow quicker; crops will produce more; it will     10     a greater range of animals, all of which will make life for human beings better.”

In 1983, he joined the army, and went to flight school He graduated in 1987 and became a     1    , In 1998, he    2     to be a member of Project 921, which is now called Shenzhou. He was one of the only 14     3     from 1,500 candidates. The team spent the next five years being trained. They not only studied all the subjects    4    to be an astronaut, but also learnt    5     skills and all about how spaceships and rockets are built. Yang     6     among the very top in the everything the group studied.

Sang Lan’s story is so special. Everyone who saw her, from nurses to famous visitors like Lconardo DiCaprio from the film Titanic, who went to see her in the hospital to     1    her up , add said she was in good     2    . Sang Lan knew that for many people the secret to happiness is to have     3     for the good things in life ,and to focus on goals, Instead of crying about what she had lost and feeling hopeless, Sang Lan thought about what she could do to get better . Her teammates were competing while she was in hospital . When they visited her and told her about their     4     she was happy for them . When the doctor told her that she would never again be a gymnast , she was able to     5     her sorrow by being proud of the things she had accomplished . She felt thankful to be alive and lucky to have the rest of her life to learn new things.

Since the 1970s many new    1     have been found for me. …I have even been put into space rockets and sent to explore the Moon and Mars.     2    , my goal is to provide humans with a life   of high quality. I am now truly filled with happiness that I am a    3     friend and helper of the human race.
