A camera and a computer can “see” something that perhaps millions of pairs of eyes failed to see for 480 years: the Mona Lisa’s necklace. The discovery about the famous painting was made by an American physicist.

The Mona Lisa, painted by the Italian, Leonardo da Vinci, has been on show for many years in Paris. Now a row of white spots on the neck have been “seen”. They are said to be the remains (痕迹) of a necklace which the artist later painted over.

The painting will be examined further by using infrared scanning (红外线扫描) techniques. Laser (激光) technology can be used to show what lies directly under the surface of the finished work, too. This will help us to understand how the artist drew the picture: Did he begin with a quick-made drawing or have second thoughts as he painted the picture?

This kind of knowledge will show us the famous artist at work. It may also help to explain Mona Lisa’s smile, which has puzzled art lovers for centuries.

Did you know that something as simple as the wallpaper on your computer can tell people a lot about you? According to researcher Donna Dawson,our computers say something about what we're like because they are part of our “personal space.”

A picture of a child or family on the screen often means the person cares deeply about their loved ones.A photo of the person surrounded by friends shows they value their popularity and probably work well with other people.On the other hand,pictures showing examples of past successes,like winning a prize may mean a person is only interested in themselves.

Pictures of nature and natural scenery tell people that you are driven to succeed and use the pictures to relax and remove the pressure（压力）in your life.Cityscapes,pictures of cities or towns,show that you enjoy travel and adventure.Most people with cityscapes as their wallpaper are optimistic（乐观的）,happy people who feel even better thinking about the places they’ve visited or want to visit.

Pictures of animals show that you are optimistic and kind-hearted.You are often happy and you enjoy life and act young.Cartoons（漫画）or drawings show that you are a multitasker,someone who does many things at once.You have many responsibilities,but you deal with them well.That's one reason you like having something to smile about when you look at your computer wallpaper.

Do you have a dream, something you always see yourself doing? Perhaps you see yourself as a lawyer, businessman, or even a scientist. Whatever it is, don’t let it die.

A dream is a wonderful thing. It can give you hope for your future and encourage you to try when all odds are against you.

However, there are dream killers that want to kill your dream. They may tell you that it is impossible for you, that you are not smart enough or that it’s never been done before. However, many times the biggest dream killer is yourself.

Don’t let fear, doubt or lack of finances prevent you from fulfilling（实现） your dream. Talk back to these killers, “I can and fulfill my dream.” You may have to do this every day. The more often you talk to your heart that you can do it, the more safely your dream will be held within you.

It is very important to take steps towards fulfilling your dream. For me, in order to fulfill my dream of one-day owning my own magazine, I needed to go back to school and finish my college degree. For you, it may be something different. You know deep inside what the voice of your dream calls for. Don’t be afraid and just do it. Try not to let too much time go by. Time is another one of those dream killers.

Think about the words of a song by Yolanda Adams, “Keep the dream alive. Don’t let it die. If something deep inside keeps inspiring you to try, don’t stop. And never give up. Don’t ever give up on you. Sometimes, life can place a stumbling block in your way. But you have to keep the faith.”

When you dream, dream big and never give up. Your dream is just yours. Never let anyone tell you that your dream can’t happen -- it can! Keep seeing yourself do what’s never been done before. As you continue to feed your dream and protect it, not only will you keep it alive, but it will come true.

1.What does the underlined words “all odds are against you” in Parragraph 2 mean?

A. You are in hopeless situation.

B. You find everything seems strange.

D. You have all your friends against you.

A. It takes money to fulfill our dream.

B. The first step is to know our dream.

C. It is important for us to take action.

D. We should not listen to the call of our heart.

高一英语单项填空简单题查看答案及解析

We've known for years that plants can see,hear,smell and communicate with chemicals.Now, reported New Scientist,they have been recorded making sounds when stressed.

In a yet-to-be-published study, Itzhak Khait and his team at Tel Aviv University, in Israel, found that tomato and tobacco plants can make ultrasonic(超声的)noises. The plants "cry out" due to lack of water,or when they are cut. It's just too high-pitched(音调高的）for humans to hear.

Microphones placed 10 centimeters away from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz(干赫兹)。Human hearing usually ranges from 20 hertz to 20 kilohertz."These findings can change the way we think about the plant kingdom,”they wrote.

On average,"thirsty"tomato plants made 35 sounds an hour,while tobacco plants made 11. When they were cut,tomato plants made an average of 25 sounds in the following hour,and tobacco plants 15.Unstressed plants produced less than one sound per hour,on average.

Perhaps most interestingly,different types of stress led to different sounds.The researchers trained a machine-learning model to separate the plants' sounds from those of the wind,rain and other noises of the greenhouse.In most cases,it correctly recognized whether the stress was caused by dryness or a cut.Water-hungry tobacco appears to make louder sounds than cut tobacco,for example.Although Khait and his colleagues only looked at tomato and tobacco plants,they think other plants also make sounds when stressed.

If farmers could hear these sounds,said the team,they could give water to the plants that need　 it most.As climate change causes more droughts,they said this would be important information for farmers. "The sounds that drought-stressed plants make could be used in precision(精准) agriculture, "said Anne Visscher at the Royal Botanic Gardens,Kew,in the UK.

Khait's report also suggests that insects can hear the sounds up to 5 meters away and respond. For example,a moth(蛾子）may decide not to lay eggs on a water-stressed plant.Edward Farmer. at the University of Lausanne,Switzerland,is doubtful.He said that the idea of moths listening to plants is"a little too speculative”。

If plants are screaming(尖叫）for fear of their survival,maybe we should be glad we can't hear them.

1.Paragraph 3 mainly explains_______.

A.where humans differ from plants

B.how the research was carried out

C.what the findings of the study are

D.why humans can't hear the cries of plants

2.Which of the following is TRUE according to the study?

A.All plants make sounds when they feel hungry.

B.Stressed plants make more sounds than unstressed ones.

C.Tobacco plants are more afraid of thirsty than being cut.

D.The more stressed a plant is,the louder sounds it makes.

3.What does the underlined word"speculative"in Paragraph 7 probably mean?

A.Surprising.

B.Uncertain.

C.Incorrect.

D.Unique.

4.What is the best title for the text?

A.Deaf humans

B.Stressed plants

C.Silent screams

D.Precision agriculture
