For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy(隐私). Would you want to have a video phone conversation with someone after you just step out of the shower(淋浴)? Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.

Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents (啮齿目动物) and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well.
“This is a huge find,” says Rick Greenwood, a scientist studying the site. “I don’t think most people had any idea that those types of animals were wandering around here more than a million years ago.”
San Timoteo Canyon is located about 85 miles from Los Angeles. The area of the canyon where the fossils were found was once part of a green river valley. Today, the region is dry and plant life is rare.
Most of the fossils are well preserved. Experts say a muddy lake bed may have trapped thirty animals that wandered over for a drink. The mud helped to protect the animal fossils.
The remains are a million years older than those discovered at the famous La Brea Tar Pits in Los Angeles. Scientists studying the bones will be able to learn more about how the animals adapted to changes in the environment.
“We have a confused view of what this time period was like, ” says another scientist. “A discovery like this could really be an important contribution.”
About 35 different animal species are represented in the fossil collection. Scientists began removing bones from the site last fall. The project was completed this summer. Starting next year, the fossils will be on display at the Western Science Center in the nearby city of Hemet, California.
小题1:
What does the passage mainly focus on?

B.the canyon in ancient times was quite different. |
C.more research work will be carried on in the canyon. |
D.the river water helped to protect the animal fossils. |
Compared to the discovery at the La Brea Tar Pits, the canyon-involved fossils _______.
A.are far older | B.include more species |
C.are better preserved | D.make experts more confused |
What do we know about the fossils from the passage?
A.All of them are of new species. |
B.Some of them have been destroyed |
C.They were looked for under experts’ guidance. |
D.They will be on show in the near future. |
Like many other birds, the ostrich swallows small stones that stay inside its “gizzard”. The gizzard is a bird’s second stomach. It is where the food is ground up. The small stones help to grind up the food so it can be digested. The small stones do the chewing because birds don’t have teeth. In that case of the ostrich with the diamonds, the bird simply had expensive taste in rocks. It used the diamonds to digest its dinner.
Diamonds and stones aren’t all that an ostrich will swallow. If there are no stones around, it will eat just about anything. Sadly for ostriches in zoos, this can be a fatal habit. The tendency to swallow anything it sees has caused the death of many an ostrich. Cruel or careless people often throw things into the bird’s living space. They throw keys, coins, and even large objects such as horseshoes. The ostrich swallows them without hesitation. Coins can be the worst. Inside the ostrich they wear down to a razor-sharp edge. They will cut open the bird’s gizzard from the inside. When one young zoo ostrich died, 484 coins weighing more than eight pounds were found in its gizzard.

This nature reserve has had a lot of work done recently in order to help butterflies. Management of the land has included bringing in sheep to keep the grass under control in a more natural way and planting wild flowers for butterfly species. The nature reserve is home to a number of butterfly species. In fact the way that this reserve has been managed means that it is probably the best reserve in Hertfordshire to see butterflies with at least 25 species now living in the area.
There are a number of threats to British butterflies and the greatest threat is the loss of their habitat. Changing farming practice has affected British native butterfly species greatly with many more now being at risk. Butterflies are such an excellent species that they can clearly tell the situation of local environment because they are easily influenced by environmental changes, A wide species of butterflies will generally mean a healthy environment.
The type of land management at the nature reserve in Hertfordshire offers a hope for many species of butterfly to live as usual. Butterflies need all the help they can get at the moment. Although the number of butterflies is beginning to increase, many are still at risk.

Over 550 meters, it is one of the tallest building in the world; on a clear day the view is wonderful. Each year, around 2 million people take the elevator ride to the top of the tower to take in the breath-taking view at the top of the world. Once you are at the top, see if you have the courage to walk across the see-through glass floor .
If you are hungry, plan to eat at the revolving restaurant at the top of the tower. The floor in the 360-degree restaurant rotates once every 72 minutes allowing everyone a complete view of the city below. The CN tower has broken record many times, winning such titles as World’s Longest Metal staircase ,World’s Tallest building and , most recently , World’s Highest Wine Cellar. In 1995, the CN tower was considered as one of the seven wonders of the Modern World.
Today, the top of the tower, more than 333m in the air, serves as the year-round workplace for more than 550 people. The tower’s workers help to make the world-class attractions and food there.
While at the CN tower, you’ll also have the chance to visit gift shops. You will find the CN Tower in the heart of downtown, on Front Street. On the north shore of Lake Ontario, the CN Tower is open 364 days a year(closed on Christmas Day).

Successful people are nicer to those who are jealous of them, psychologists have found.
The fear that they may become the target of malicious(恶意的)envy makes people act more helpfully toward people who they think might be jealous of them.
Previous research found jealousy could be divided into benign and malicious envy. Those with benign envy were motivated to improve themselves, to do better so they could be more like the person they envied.52-------- The Dutch researchers then set out to question the effect on the target of the envy.
In lab experiments a group of people were made to feel like they would be maliciously envied by being told they would receive an award of five euros(欧元)53-------The researchers thought that the deserved prize would lead to benign envy, while the undeserved prize would lead to malicious envy.
Then the volunteer was asked to give time-consuming advice to a potentially envious person.People who had reason to think they would be the target of malicious envy were more likely to take the time to give advice than targets of benign envy.
In another experiment, an experimenter dropped a number of erasers on the floor as the volunteer was leaving.54-------- He said: "This sort of serves a useful group function. We all think better-off people should share with others but that"s not something we are inclined to do when we are better off..55----------
A.Those who thought they would be maliciously envied were more likely to help him pick them up. |
B.Helping others is a virtue. |
C.However those with malicious envy wanted tobringthe more successful persondown. |
D.Malicious envy. is terrible. |
F. People are more likely to help others if they think they are envious of them.
G.. Sometimes the prize was deserved and was based on the score they were told they had earned on a quiz. But sometimes it was not based on their score at all.
