Three Things to Do Before You Are 18
Are you bored with your daily life? Here are some things you should try before you are 18.
★Learn to swim
Seriously, this is so important that it can save your life. If you can’t swim well, you won’t be able to dowater
sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make sure you do it.
★Try at least one kind of team sports
Being a good team player is an important skill in life. You can’t just think of yourself, but have to work well
with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit
and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and
make many friends.
★Collect something
One of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could
collect things that make you remember what you have done, like cinema tickets for films you have seen or letters
from friends. The best way to collect is to have a special album to put your collection in and to write what each
thing means to you. That way you won’t forget.

B Scientists have recently discovered thatAndean condors (秀鹫)— some of the world’s largest birds——barely
flap their wings at all while flying. Instead, they use rising air currents to remain in the air for hours.
The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when
spread out, measure up to three meters. Their main food source is the meat of large animals which have died.
Soaring high in the sky allows condors to easily spot possible meals on the ground.
Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use
when flying. To study the birds while they were in the sky, the researchers attached special devices which could
record every beat of their wings.
The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off.
Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their
wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly
117miles.
Soaring without flapping is important because birds bum energy every time they flap their wings.
The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, it
often creates “thermals”— currents of warm air moving upward. The condors soar by making use of these
thermals. The tricky part is finding thermals and moving between them.
When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned
that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the
ground and looking for a new thermal.
The scientists reported that even though all of the condors they studied were young, they knew well how to
take advantage of the air currents.
4. What can we learn about the Andean condor from the text?
A. They live mairly on small animals.
B. Their wingspan is at least three meters.
C. They rely on hot air to remain high in the sky.
D. They are the birds with the strongest flying ability.
5. Why was the equipment tied to the birds?
A. To measure how far they could fly without flapping.
B. To keep track of how often they flapped while flying.
C. To calculate the energy required for their flight. D. To confirm their flight patterns.
6. Which of the following acts consumes the most energy for a condor?
A. Hunting for food. B. Flying in the sky.
C. Getting off the ground. D. Landing on the ground.
7. What can we infer from the text?
A. Condors flap the most when looking for a new thermal.
B. No condor can fly for more than five hours without flapping.
