The Open University is unique in that it es students of all ages。

including those who left school two decades ago。

However。

all students must be at least 21 years old。

This sets it apart from nal universities。

as its students are typically employed full-time or
stay at home。

such as mothers with families。

Unlike other universities。

there are no entrance exams required to enroll in courses at the Open University。

This is why it is called an "open" university。

The n was founded with the purpose of assisting a specific group of individuals who missed out on obtaining a university n when they were younger。

Overall。

the Open University provides a flexible and accessible approach to higher n。

Its diverse student body includes individuals who may have missed out on nal university opportunities due to work or family ns。

The university's lack of entrance exams makes it an attractive n for those who may not
have achieved stellar academic results in the past。

The Open University's n to provide n to those who may have missed out earlier in life is truly admirable.
The Open University。

originally named "The University of the Air," was founded with the n of providing n through。

and n broadcasts。

While these mediums have allowed for a classroom experience in people's homes。

they alone are not sufficient for a university n。

To supplement this。

the Open University has 283 study centers across the country where students can receive guidance and advice。

nally。

students are required to send written work to a tutor for 36 weeks of the year and must spend three weeks as a full-time student during the summer。

Tutors and students also have the opportunity to meet and study together。

similar to nal universities。

they can complete their studies in four to five years.

Throughout history。

humans have come to terms with the inevitability of death for all living things。

While people now live longer than they used to。

the effects of aging are still evident。

Aging is not a disease。

but as a person ages。

the cells and organs of the body do not n as efficiently as they did in youth。

This can result in a weaker immune system and a greater susceptibility to disease.
There are us factors that contribute to aging。

Some cells in
the body have a longer lifespan but are not replaced when they die。

As a person ages。

the number of brain and muscle cells decreases。

Other cells in the body die and are replaced by new ones。

but in
older individuals。

these new cells may not develop as well as those in younger people。

Overall。

aging is a natural process that occurs as the body changes over time。

While it is not a disease。

it can lead to a weaker immune system and a greater risk of illness。

Understanding the causes of aging can help individuals take steps to maintain their health and well-being as they age.
Which of the following is a factor in aging?
A.Living in a polluted environment.
B.Eating too many fruits and vegetables.
C.Changes in protein chemicals in cells.
D.Exercising regularly.
答案关键: C
改写建议：
Aging is a complex process that involves us factors。

One of these factors is changes in protein chemicals within cells。

As people age。

these chemicals e less elastic。

which can lead to wrinkles and loose skin。

nally。

this loss of elasticity can cause a
decrease in height among older individuals。

It is important to note that aging is not a disease and happens to everyone。

While organs may not n as well in old age and there may be a decrease in n against disease。

living in a polluted environment or eating too many fruits and vegetables are not identified as factors in aging。

However。

regular exercise can help slow the aging process and promote overall health.
Possible revised n:
Which factor may not contribute to aging according to the passage?
A。

Non-replacement of some body cells after they die.
B。

n in the number of brain cells.
C。

n in the number of muscle cells.
D。

Answer key: D
What is the main topic of this passage?

The causes of aging.

Answer key: D
When three people observe a busy street corner from the same window。

they are likely to report different ns of the same scene.
n occurs within our minds。

When three people look out a window。

each may perceive something different based on what their senses。

particularly their eyes。

tell them。

For example。

one person may see a police officer giving a ticket to a motorist。

another may see a traffic jam at a busy n。

and a third may see a woman attempting to cross the street with several children。

This illustrates how n is the mind's n of sensory n.
Numerous psychologists are currently studying how individuals perceive the world around them。

Through scientific n。

these psychologists are able to control all variables and measure
the results of multiple experiments。

By doing so。

they aim to determine what factors contribute to people perceiving the same scene in vastly different ways。

Answer: B。

Two separate ns.
Perceiving is a fundamental cognitive process that occurs in every person's mind。

It involves the n of sensory n from the environment。

including visual。

auditory。

and tactile stimuli。

People can perceive different things about the same scene due to individual differences in n。

past experiences。

and cognitive biases。

Psychologists study n by setting up many experiments to investigate how people perceive and interpret sensory n。

Through scientific research。

we can learn more about our minds and how they process n。

Therefore。

the best title for this passage is "Learning about Our Minds Through Science."。
