1、The Book of Life
So far, scientists have named about 1.6 million living species, and that's a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.
To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, for example, will be able to input which bird they've seen and where. The technology for this kind of tool has only become available.
As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven't been reviewed.
Another convenient feature of the EOL is that you'll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.
It now takes years for scientist to collect all the data they need to describe and analyze species. The creator of the Encyclopedia of Life hope that their new tool will speed up that process.
The goal of the creation of the EOL is to ______.
【单选题】

A.collect enough data to analyze the living species on Earth

B.work out an easy -to - use catalog of every living species on Earth

C.enlarge an existing Web site of the living species on Earth

D.add new information to the existing databases of the living species on Earth

正确答案:B

答案解析:本题有一定难度,需要读懂句意。带着题干信息词回文章定位,答案依据主要在文章第二段后面两句:An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single,easy - to - use reference guide.谈到了物种百科网站创建的目的,回来看选项,B项和原文句意相近,是答案。

2、Weaving with Light
In the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did-without electricity. That's because it's too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. And without electricity, at home or on the road, they can only work during daylight hours. When it gets dark, they must stop whatever they're doing.
Now, a team of scientists, designers and architects is using new technologies to provide the Huichol with light after the sun sets. The scientists technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, or other items.
By collecting the sun's energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights," Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy.
"Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States and move it into new markets for people who didn't have a lot of money."
At the core of Portable Light technology are devices called high - brightness light - emitting diodes, or HB LEDs. These tiny lights appear in digital clocks, televisions and streetlights.
LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give off light we can see.
Ninety percent of energy produced by incandescent lights, however, is heat and invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken.
LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules and their particular arrangement determines what color is produced.
To make a living, the Huichol create artwork and ______.【单选题】

A.sell it to tourists in their villages

B.sell it in cities far away from their villages

C.display it in their village museums

D.keep it in their homes to attract tourists

正确答案:B

答案解析:本题难度不大,答案依据比较明显,带着题干信息词回文章定位,答案依据主要在文章第一段第四句:They sell their art, in cities hundreds of miles away from their villages.回来看选项,C项和原文句意相符,答案是B。

3、Rockets in the Sky
If someone asked you. "What color is the sky?" I expect that you would answer, "Blue." I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air.
We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air. What is the sky? The sky is space. In this space there is nothing except the sun, the moon and all the stars.
Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal.
The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
I am sure that you are asking. "How does a rocket fly?" If you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through neck of the ball off and this pushes the balloon through the air. It does not need wings like an air plane.
This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air.
Rockets can fly far out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space.
A rocket can fly to the moon because____.
【单选题】

A.it looks like a balloon.

B.it is much lighter than an airplane.

C.it doesn't have wings.

D.it works like an untied balloon.

正确答案:D

答案解析:文章第6段都在综述气球的飞行原理来解释火箭的工作原理,因此选D。

4、Halloween
Halloween is an autumn holiday that Americans celebrate every year. It means "holy evening", and it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches and evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, and the farm workers and their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, and ask them to help keep the evil ones away.
Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, and over each of the stable doors a few rowan leaves would be hung. Witches and evil spirits would not go anywhere near the rowan tree.
In more recent times, Halloween has become a time for the parties, when children dress up as witches and play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes and a lot of other delicious things to eat.
But for the most part the children enjoy the fun of dressing up and playing their favorite game of "Trick or Treat". They run down each street knocking on the doors crying loudly "Trick or Treat! Money or eat!", and most people have some sweets or money ready to give them. Those that do not can expect maybe to have a tyre flattened, or their windows covered in soap. Or the children may just knock on the door and run away.
Some children think of other people on Halloween. They carry boxes for UNICEF (The United Nations International Children's Emergency Fund). They ask for money to help poor children all around the world. Of course, every time they help UNICEF, they usually receive a treat for themselves, too.
Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins and put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year.
Why did people hung rowan leaves over the stables?
【单选题】

A.Because farm animals liked rowan leaves.

B.Because rowan leaves would keep witches and evil spirits away.

C.Because they used the leaves to decorate the stables.

D.Because rowan leaves could keep the farm animals quiet in the stables.

正确答案:B

答案解析:第2段最后一句,巫师和邪恶精灵不敢靠近花椒树,因此选B。
