The Lost Generation

by Jonathan Reed

I am part of a lost generation.

And I refuse to believe that

I can change the world.

I realize this may be a shock, but

'Happiness comes from within'

Is a lie, and

'Money will make me happy'

So in 30 years, I will tell my children

They are not the most important thing in my life.

My employer will know that

I have my priorities straight because

Work

Is more important than

Family

I tell you this:

Once upon a time

Families stayed together

But this will not be true in my era.

This is a quick fix society

Experts tell me

Thirty years from now, I will be celebrating the tenth anniversary of my divorce.

I do not concede that

I will live in a country of my own making.

In the future,

Environmental destruction will be the norm.

No longer can it be said that

My peers and I care about this Earth.

It will be evident that

My generation is apathetic and lethargic.

It is foolish to presume that

There is hope.

And all of this will come true unless we reverse it.

Travelling can be an expensive hobby but it also is compensates the financial loss with all benefit. If a travelers have interest in life and its manifestations, they can find much to keep themself happy and absorbed. One can definitely find everything that satisfies his intellectual and sensuous cravings.

As a hobby, travelling keeps us busy during leisure time; it is the best method to use time. Till a person breaks from dull routine, physically and mentally; one cannot find satisfaction. Travelling helps us to achieve this break. At a new place, one is curious to know and eager to gather all the unknown information about the place which he has neither read nor heard before he gets thrills and surprises which keep the interest and enthusiasm alive and encourages us to keep our journey on.

While travelling, one comes across a number of people from varied backgrounds and places. By interacting with them, he comes to know about their heritages also. In case one has psychological bent of mind, one increases one’s experience and power to understand others. Understanding human nature is, perhaps, the best part of education. Travelling satisfies all demands of a good hobby – it is absorbing education and refreshment to the mind, body and soul.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.

A newborn baby can see, hear and feel. By the age of five, a child can talk, ride a bike and invent imaginary friends. How does this development happen? We don't understand the way language, thinking and planning develop very well. Now scientists are using new technology to ‘see’ into children's brains. And they are discovering new information about the way a baby's brain develops.

A study in 2010 showed that the experiences a child has in their first few years affect the development of the brain. It showed that children who received more attention often had higher IQs. The brain of a newborn baby has nearly a hundred billion neurons. This is the same number as an adult's brain. As they grow, a baby receives information through the senses of sight, hearing, smell, taste and touch. This information creates connections between different parts of the brain. At the age of three, there are a hundred trillion connections.

One experiment looked at images of babies' brains while they were listening to different sounds. The sounds were in different sequences. For example, one sequence was mu-ba-ba. This is the pattern ‘A-B-B’. Another sequence was mu-ba-ge. This is the pattern ‘A-B-C’. The images showed that the part of the brain responsible for speech was more active during ‘A-B-B’  patterns. This shows that babies can tell the difference between different patterns. This experiment is interesting because sequences of words are important to grammar and meaning. Compare two sentences with the same words in a different order: ‘John killed the bear’ is very different from ‘The bear killed John.’ So babies are starting to learn grammatical rules from the beginning of life.

Researchers also know that babies need to hear a lot of language in order to understand grammar rules. But there is a big difference between listening to television, audio books or the internet, and interacting with people. One study compared two groups of nine-month-old American babies. One group watched videos of Mandarin Chinese sounds. In the other group, people spoke the same sounds to the babies. The test results showed that the second group could recognise different sounds, however the first group learned nothing. The scientist, Patricia Kuhl, said this result was very surprising. It suggests that social experience is essential to successful brain development in babies.

What did the study described in the last paragraph do? 

A. compared the effects of different languages 

B. divided babies into two groups with different treatment 

C. investigated if babies can learn Chinese
