1 . What will people die of 100 years from now? If you think that is a simple question，you have not been paying attention to the revolution that is taking place in bio-­technology（生物技术）. With the help of new medicine，the human body will last a very long time. Death will come mainly from accidents，murder and war. Today’s leading killers，such as heart disease，cancer，and aging itself，will become distant memories.
In discussion of technological changes，the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells（细胞） are the basic units of all living things，and until recently，scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells，such as those of brain cells，would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100，medicine will have advanced to the point at which every 10 years or so，people will be able to take medicine to repair their organs（器官）. The medicine，made up of the basic building materials of life，will build new brain cells，heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence，but many technical problems still must be cleared up on the way to this wonderful future.

2 . Life can be so wonderful, full of adventure and joy. It can also be full of challenges, setbacks and heartbreaks. Whatever our circumstances, we generally still have dreams, hopes and desires—that little something more we want for ourselves and our loved ones. Yet knowing we can have more can also create a problem, because when we go to change the way we do things, up come the old patterns and pitfalls that stopped us from seeking what we wanted in the first place.
This tension between what we feel we can have and "what were seemingly able to have is the niggling   suffering, the anxiety we feel. This is where we usually think it's easier to just give up. But we're never meant to let go of the part of us that knows we can have more. The intelligence behind that knowing is us—the real us. It's the part that believes in life and its possibilities. If you drop that, you begin to feel a little "dead" inside because you're dropping "you".
So, if we have this capability but somehow life seems to keep us stuck, how do we break these patterns?
Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today's challenges.
While, deep down, we know we can do it, our mind—or the minds of those close to us—usually says we can't.
That isn't a reason to stop, it's just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It's all about starting simple and doing it now.
Decide and act before overthinking. When you do this you may feel a little, or large, release from the jail of your mind and you'll be on your way.

3 . Let us suppose it is now about A.D. 2060. Let’s make believe (假设；虚构) it is about sixty years from now. Of course, things have changed and life is very different.

Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment (娱乐) of young and old.

What are people eating now? People are still eating food. They haven’t yet started to take on heir (继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.

Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.

Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.

People are now largely vegetarians (素食者). You see, as the number of people increases, the number of animals decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.

Such would be our life in 2060.

1. According to the passage, what will be on the moon in about A.D. 2060?

A．Many tourists.	B．Many other animals.
C．Many plants.	D．A sea.

2. What will people eat then according to the passage?

A．Biscuits in pill form.	B．Foods in pill form.
C．Foods in water form.	D．Foods in gas form.

3. The passage tells us that in 2060, ________ on the earth than now.

A．there are fewer population	B．there are more pests
C．there is less water	D．the crops are getting better

4. Why are people largely vegetarians in 2060?

A．Because they don’t eat meat.

B．Because doctors advise them not to eat meat.

C．Because the number of animals decreases.

D．Because all the animals have died of diseases.

4 . Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a territory is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting(筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.
1. Some scientists believe that most of the time bird’s singing is actually ________.

A．an expression of happiness	B．a way of warning
C．an expression of anger	D．a way of greeting

2. What does the underlined word “territory’’ mean?

A．A place where families of other species are not accepted.

B．A place where a bird may shout at the top of its voice.

C．An area for which birds fight against each other.

D．An area which a bird considers to be its own.

3. Why do birds keep on singing at nesting season?

A．Because they want to invite more friends.

B．Because their singing helps frighten outsiders away.

C．Because they want to find outsiders around.

D．Because their singing helps get rid of their fears.

4. How does the writer explain bird’s singing?

A．By comparing birds with human beings.

B．By reporting experiment results.

C．By describing birds’ daily life.

D．By telling a bird’s story.
