•Read the following passage below about Chicago.

•For questions 23 - 28, choose the correct answer.

•Mark one letter (A, B or C) on your Answer Sheet.

Chicago

Chicago, lying in the east of the USA, is the rather young American city. It was almost completely rebuilt after the Great Fire of 1871. One's first impression of the city may include streams of cars running to-and-fro on the highways, skyscrapers and the wide green water of Lake Michigan, which lies to the northeast of the city. The area of the city is over 228 square miles with a population of about 3 million.

The climate of Chicago on the whole is almost the same as that of Beijing with rather hot days in summer, colorful and fresh days in fall and icy but often clear days in winter. The spring in Chicago is a little changeable in temperature. For instance, I saw a snowfall in early April this year while some of the flowers were already in full bloom. Chicago is also famous for its frequent strong winds, and as a result has got the name of "the Windy City".

Chicago is a rather young American city because.

A．it was completely rebuilt in the late 19 century

B．there are smaller areas in Chicago than in Beijing

C．its population is in fact rather small

It is true that as a social organization moves from the simple to the complex, so does the organization through which it educates its children. Growth and change are vital f education is to meet new needs and demands. In a very simple social order it may suffice to have the parents carry on the education of their children. However, as will be shown later in more detail, such a method may become entirely untenable, and special individuals are entrusted with the task. These may be hired privately at first, but soon the social group---the church, village, and the like--will be responsible for education. Eventually, special training is needed. Thus the influence of the local governmental unit, such as the town, township, and later the state or the province, becomes necessary. It was generally considered simpler to use as a unit the already existing local unit.

The writer would probably argue for ______.

A．more parental influence in education

B．an educational system which takes social complexity into account

C．strict state control of education

D．more special training for teachers
