In the summer of 1848, in Guatemala, a man called Ambrosio Tut went into the jungle, as he did almost every day. Tut was a gum-collector(树胶采集者),(look) for gum in the jungle. To do this, he had to climb the trees.
this particular day, he got to the top of one tree and something caught his eye. He looked out across the trees and saw the tops of some old buildings.
Tut didn't really know what he had seen but he knew it was something (specially). He ran to tell the local governor, and together they
(walk)into the jungle. There they found Tikal(蒂卡尔),the city that the Mayans (玛雅A) had built many hundreds of years before. The two men saw temples and pyramids, squares and houses, and places
kings had lived when the Mayan people ruled the region.
For a long time before that day, local people had known that somewhere in the jungle there was an old Mayan city, no one had seen it for centuries.
200 and 900 AD, the city of Tikal had been the center of Mayan civilization in the region, but then the Mayans left
─nobody knows why! After 1000 AD, the jungle began to cover it and people forgot that it was there.
Seven years before Tut looked out for the trees, two British explorers had gone to Guatemala and had written a report about Mayan treasures in the jungle, but they didn't mention Tikal. Even (early)than this, local Indians had told European travelers about a great city
(hide) in the trees, but no one would listen to them. Now the lost city had been found again, and archaeologists (考古学家) went there immediately to see it.

(hard). It called for a complete change in my view on life. Here is the method I tried.
Each morning during a fifteenminute bath, I determined to cultivate a big, happy smile. I found out, however, that it couldn't be a (force) smile developed just for the purpose of putting dollars in my pocket. It had to be
honesttogoodness smile from down deep inside, an outward expression of happiness from within!
Let's see starting off with a good fifteenminute training of the smile muscles helped me during the day.
entering an office I would think of many things I had to be thankful for, work up a big smile and then enter. Seldom did it fail

What do people do with their old, out of date but still useful computers? Most people don’t know to do with them. Many old computers are put away in homes. Many more
(throw) away as rubbish.
Finally, some companies are thinking of ways (bring) down the number of old computers. Sony has agreed to help recycle old Sony products. Dell, Hewlett Packard and other
(company) now also take back some old computers.
In some countries, laws have been passed, too. Computer companies have to pay for collecting and (recycle) their used products. And 70% of computer waste must be recycled. The idea behind the laws
(be) that computer companies themselves should pay for the cost. That will encourage them to make computers
(easy) to repair and upgrade (升级).
Yet while many people are throwing away good computers, others cannot afford at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.
computers then go to schools, charities (慈善团体) and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish
someone else's useful things and cut down waste, too.

A
History is one long story, or (real), a lot of stories of competing narratives (叙述),
about the people who shaped the world we live in.
Family history can give people a sense of history that is much personal than hearing about far‑off events about
(stranger). Telling your family history is a great way for the younger members of your family
(learn) some history and really understand and connect with it.
For example, it’s much more meaningful to discover the Great Depression meant that your grandparents didn’t taste butter until
were in their teens than to hear an abstract fact that the Great Depression meant rationing (定量配给). You feel much more
(connect) to a story about your uncle’s experience of living in France than a book about it.
(tell) stories of people that you knew or ancestors
stories you know is a powerful way to help young people feel a connection to those who came before them, family and otherwise, linking the stories of the past
their own experience of the present and imaginings of the future.

In this constantly changing world, how to put the knowledge (gain) every day into
(real) has interested numerous people. As a proverb goes, “Knowledge is a treasure, but practice is the key
it.” Apparently, this saying
(try) to deliver the message
we ought not to stop practicing it if we
(true) want to master the knowledge we learn,
There are several reasons (account) for this statement. To begin with, human beings are forgetful beings; therefore, only when we use knowledge, make
(mistake), and try to use it again will we be able to remember it by our heart. Moreover, knowledge has become growingly complicated and we can seldom grasp the essence of it if we do not practice it again and again.
Practicing, to sum up, (be) of greatest importance for those who are determined to learn knowledge well. As a student, I hope that the young can focus more attention on practicing
they learn.
