50 Marathon races in America
Many Americans enjoy running. And one kind of race, the marathon, has
captured the imagination of people all over the nation. The race has roots in
ancient history. The Boston marathon in Massachusetts is the oldest marathon
which was started in 1897. It was not until 1972 that women could officially
compete in Boston. Today’s marathons do not bar anyone because of sex or age.
Racing has expanded to average runners. Hundreds of these races are organized
in America every year which are often in connection with the cause like fighting
disease or supporting local hospitals and schools.
49 Open-source software
Open source software is computer software that is available to the general
public in source code form. If a person has enough knowledge about computers
and computer programming, he or she can change the program’s source code.
The source code is like a set of directions that show the program how to operate.
People change the codes so that the program will operate in a way that will meet
their needs. Sometimes changing the code will make the program run faster or it
will take problems out of the program. These problems can cause a computer
program to shut down.
48 Pedestrian Safety
Roads are dangerous places for people on foot. So it’s important for
pedestrians to be aware that traffic may be approaching from unexpected
directions. Here is some general knowledge to bear in mind. First pedestrians are
not allowed walk along or across any motorway at any time. Second it’s advisable
to use crossings whenever you can, although it is not illegal to cross the road at
any point apart from the motorway. Third you may cross the road when the green
man is showing. You must not start to cross if the light is flashing.
47 Trees
Trees are the oldest living organisms on earth. The great age of trees makes
them useful for all sorts of scientific research. Besides, trees also have a lot to teach
us about being part of a community and how cooperation is better for a society
than competition. A community of trees growing together share all the available
resources with each other. They do this through their roots, though the soil, and
also through the network of tiny fungi growing in the soil between them. They
don’t only share with trees of the same species. Any type of tree can benefit.
46 Teaching assistants
A teaching assistant usually works about 20 hours each week. Teaching
assistants are paid to help professors teach students in entry-level study programs
(初级课程的教学). Generally the professor gives a talk (演讲) or lecture （讲课授课）
to a large group of students one or two times a week. The teaching assistant meets
with smaller groups of students during the week. The TA gives tests and reads (批
