6． The bank of England is making plans to introduce plastic banknotes to the UK．
Paper notes，meaning pieces of paper money，have been used in England for more than 300 years，but replacing them with plastic ones could be better．
  Plastic notes were first introduced to Australia back in 1988．Since then other countries，including Romania，Vietnam，Mexico and Malaysia，have also begun using money made in this way．
  Fans of water sports，such as surfing，find this type of money more useful and easier，as they can take it with them in the water and won't worry that it will fall apart．It is also good for people who by mistake put clothes in the washing machine with a note in the pocket!
  It is more hygienic （clean and free of bacteria） than paper money as it absorbs less bacteria（the simplest and smallest form of plants，some of which cause disease）．And it is stronger．This means it lasts longer．According to a survey，a usual 5 note in the UK lasts around six months，while the $5 Australian bill lasts for an average of 40 months．
  A downside of plastic cash is that it costs more money to produce．Cash and money-counting machines will also have to be adapted to accept the new money．
  It is expected that the Bank of England，who hopes to start printing plastic notes from 2015，will introduce the money slowly，using the most common notes first．
42．Which country was the first to use plastic notes？D
A．The UK．
B．Romania．
C．Vietnam．
D．Australia．
43．You can put the sentence"Besides being waterproof，there are other good effects of using plastic notes instead of paper ones．"at the beginning ofC．

44．What can you infer （推断） from Paragraph 6？B
A．Plastic notes should be printed in cash machines．
B．There are some disadvantages of using plastic notes．
C．Every country will have to accept the new money．
D．Plastic notes should be produced by the cashiers．
45．Which is NOT the reason why the UK wants to use plastic notes instead of paper ones？A
A．They take up less space．

12．Many people like diving（跳水） in water because they can explore（探险） the underwater world．But there is another kind of diving，some people dive in the sky!This is really a very exciting sport．A skydiver goes high up in the air on a plane．Then he jumps off the plane and floatsC漂浮）in the air with the help of a parachute．A parachute is like a huge umbrella，it is put on the back of the skydiver．When the skydiver reaches a certain height，he will pull a string（绳子） and the parachute will open up in seconds and carry him gentle down to the ground．Skydivers like doing a lot of fantastic tricks in the air．After jumping off the planes one after another，they will try to stay in the air and hold each other's hands．They can form different shapes．
Is it safe to do skydiving？Yes，if we receive proper training．But sometimes，accidents do happen．In Canada，two skydivers were killed in 1991when they jumped off the plane but their parachutes got tied up （缠住）each other．The parachutes could not open up and both crashed down and died．

66．Why do people like diving in water？Because they can explore the underwater world．
67．How does a skydiver go up into the sky？By plane．
68．Is a parachute like an umbrella？Yes，it is．
69．What will a skydiver do to open his parachute？He will pull a string when the skydiver reaches a certain height．
70．Is it always safe to do skydiving？No，it isn't．．
