How do we know the time? A clock, a watch or a mobile phone can help us. However, many years ago there were no clocks and knowing the time was not so easy.


        About 5, 500 years ago, the Egyptians invented the sun clock. This was a tall stone building. Its shadow (影子) showed the movement of the sun. So people were able to know midday. The Egyptians made a sundial about 3,500 years ago. It was smaller than the sun clock and could let people know the time for half a day. On cloudy days or at night it was impossible to tell the time with a sun clock or a sundial. Water clocks were the first clocks not to use the sun. The idea is simple. Water flows (流动) from one bottle to another. When the water reaches a certain level, it shows the hours. The Egyptians used water clocks about 3,400 years ago. These clocks were popular in the Middle East and China. But they failed to make people know the exact time.
        In the 13th century, the mechanical clock was invented. This was more exact, but it was expensive to make one. Over the next few centuries it was developed. For example, springs(发条) were added. This enabled people to get the correct time and allowed clocks to be smaller. In 1927, the first quartz clock was developed. Clocks became cheaper to build. It's also cheaper for ordinary people to own a clock. People began depending on them more and more to run businesses, markets and so on. More recently, in 1956, came the digital clock. And
nowadays satellites send our mobile phones the time to the exact second.

There has been a lot of progress in timekeeping. Clocks are always changing but some things never change.

文章大意:本文主要通过两个故事解释白鸽为什么是和平的象征。

【推荐1】Whenever the word “peace” comes into our mind, we can’t help thinking of a white-coloured bird with a leaf in its mouth. But do you know why this little bird became a symbol of peace?

The symbol first appeared in the story of Noah’s Ark (诺亚方舟). In the story, when the heavy rain that flooded (淹没) the earth stopped pouring down, Noah sent out (派遣) a white dove to see if there was any land. Then the dove returned with an olive branch (橄榄枝) in its mouth, which meant that it had found dry land somewhere. This brought hope to Noah. From then on, the white dove was considered the symbol of hope and new life.

In another very popular story from Central Asia, a big war was about to happen between two kingdoms. When one of the kings asked for his helmet, he was told that a dove had made a nest in it. The king’s mother wanted him to keep the nest and the doves. The king agreed and headed for the war without his helmet. After seeing this, the other king asked the reason. The king told the truth. The other king was deeply touched. And they finally agreed to make peace instead of war. A nest of doves became a reason for stopping a war. Since then, the dove has been connected with peace.

Later, many artists felt the bird is a symbol of peace. But it was Pablo Picasso who made the white dove a popular modern symbol of peace when he used it on a poster for the World Peace Congress (WPC) in 1949.

文章大意:本文主要讲述了狗理解我们说话的能力比我们想象中要好得多,它们不但能理解我们说的什么,也能理解我们说话的方式。

【推荐2】Why are dogs our best friends? Maybe because they can understand our words much better than we think, according to a study in Hungary. It found that dogs understand not only what we say, but also how we say it.

“The results were very exciting and very surprising,” said the researcher Attila Andics, from Eotvos Lorand University in Budapest.

For the study, the researchers first trained 13 dogs for months. The dogs had to sit quietly inside machines, so that the researchers could check their brain activity.

Then the researchers put headphones on dogs and played people’s voices to them. There were four different voices. Some were positive words, such as “well done”, or neutral(不带感情色彩的)words like “however”. The words were also in different tones(音调). Some were positive and some were neutral.

Brain scans(扫描)showed that the dogs could recognize(辨认)words, as well as the tone of words, much like people do. The positive words with a positive tone brought the stronger activity in their brain’s reward centers(反应中枢).

“It shows that for dogs, a nice phrase can work very well as a prize, but works best if both words and tones match,” said Andics.

They also found that dogs deal with meaningful words with the left side of the brain and tones with the right. Human brains work in the same way.

It gave us a new understanding of language, said Andics. That is, not only humans understand the meaning in words, other species(物种)do too.

1. What was found according to the study in Hungary?
A.Dogs can’t understand people’s words.
B.Dogs can only understand what we say.
C.Dogs understand not only what we say, but also how we say it.
D.Dogs can understand what we thought better than our words.

A.Dogs deal with meaningful words with the right side of the brain.
B.Human brains run in the same way as dogs’ do.
C.The researchers trained the dogs for years to check their brain activity.

【推荐3】根据短文内容,从短文后的 A-F 选项中,选出 5 个适当的选项补全短文(有一多余选项)。

Seeing blood in a scary movie might make you cover your eyes, but real blood isn’t scary at all.    1    That’s why blood donors are thought to be lifesavers.

Blood donors are those giving blood — usually about 200ml at a time — to blood banks or blood donation (捐赠) centers.    2    For example, someone may have lost blood in accidents, or have a serious illness that requires his blood to be replaced. Hospitals and blood banks store the blood and try to keep enough on hand.

    3    Medical workers ask donors several questions to make sure the blood is safe to use. Then the donors relax, often reading a magazine or talking as their blood is drawn. Afterward, the donors may receive some juice or water and maybe fruit to give them energy. The process is simple, not scary.    4    To give blood, a person must be at least 18 years old and must meet certain other requirements.

Students of all ages, though, can learn more about the donation process by visiting a local blood donation center.    5    It is also an easy way to help a community.

A.Then the blood can be used for people in need
B.Donating blood is not only one of the easiest ways to save lives.
C.In fact, blood is the gift of life and keeps us alive.
D.Donating blood is not difficult.
E.Most people are able to donate blood again in several months if they wish
F.We donate blood to save others in any situation.
