What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work .So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

This morning, a Virgin Atlantic 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈)oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work. While this is a great initial step in trying to reduce CO2(carbon-dioxide) emissions(排放)from airplanes, there are a lot of hurdles(障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes(known as Jet A), biofuel freezes at high altitudes. Also, Jet ‘A’ fuel burns consistently (at the same pace), which means it provides a sale and reliable fuel for long flights – engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops, will come from clearing more of our forests and the second that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae(藻类)produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this years, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fucl may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
66.Why does Virgin Airlines try to replace normal fuel with biofuel?
A.To cut down the flight cost of the company.
B.To remove some hurdles for the biofuel to work.
C.To reduce CO2emissions from airplanes.
D.To test plane engines on biofuel.
67.Which is NOT true for a full biofuel switch of airplanes?
A.Biofuel cannot run for long flights.
B.Biofuel cannot work at high altitudes.
C.Man has not enough land to grow extra crops for biofuel.
D.It’s not easy for sewage treatment plants to manufacture biofuel.
68.One of the hurdles to be overcome for a full biofuel switch is to .
A.alter the engine for airplanes
B.make biofuel burn consistently
C.open more land to grow more crops
D.develop sewage treatment plants
69.We can infer from the last paragraph that .
A.there is a long way to go for a complete switch to alternative fuel
B.it won’t be long before alternative fuel comes into use
C.airlines, oil companies and airplane manufacturers are reliable
D.alternative fuel has a bright future
