    Venus is close to the earth.It is the second planet from the sun.The earth is the third planet from the sun.Venus is similar(相似的)to the earth in size and mass (质量).It is often described as the earth's"sister".

Scientists have been learning about Venus for a long time.First they looked at Venus through telescopes(望远镜).But Venus is covered with thick clouds.Scientists could not see Venus well through the clouds.So they made guesses about it.

For a long time,scientists thought that Venus had water and plants.They thought Venus might have animals too.But they didn't know for sure.

Then scientists found a way to learn more about Venus.In'the 1960s,they began sending probes(航天探测器)to Venus.The probes flew through the thick clouds.They took pictures of Venus up close.They found out many things too.The probes sent the pictures and things they found out back to the scientists.

The scientists learned a lot from the probes.First they learned that most of their guesses were not right.And they learned that Venus is very hot.

After that,scientists knew they could not send people to Venus.But they still wanted to know more about it.So they sent new probes.These new probes took great pictures of the planet.The pictures showed that Venus has plains (平原)and mountains!And in some ways,Venus looks like the earth.

根据材料内容完成下列任务。

任务一:简要回答下列问题。

(1)、How are Venus and the earth similar?

    There is a popular belief that goldfish only have a three-second memory. But a 15-year-old schoolboy from Adelaide has just finished an experiment to tell us that it is not true. He shows everybody that the goldfish is smarter than we think.

    "I don't believe that they had a three-second memory because animals need their memory, so they build up over time a knowledge of where the food is," said Rory Stokes, a student at the Australian Science and Mathematics School.

    He did the experiment in a small tank(鱼缸)of goldfish. "I decided to get a bit of red Logo and just feed them next to that. Every day I'd put it in and spread food around it." He said.

    "At first they were a bit scared of it, but by the end of the three weeks, they were actually almost coming before I put the food in."

    After leaving the fish alone for a week, Rory placed the red Logo block in the tank again.

    "They remembered perfectly well," he said.

    "They actually had a time faster than the average(平均)of the three feeds before I left."

    The goldfish showed that they not only could store information, but also had the ability to get it back at a later date.

    Culum Brown, a researcher at Sydney′s Macquarie University, has studied fish behavior for more than ten years.

    He says his studies of Australian native fish show fish are smart animals that know how to avoid enemies and catch food like any other animal.

    "The thing that I really liked about Rory′s experiment is that he not only got that classical conditioning going but the fact that he could get thorn next just to that specific coloured marker. I thought it was really good." He said.

    Watering plants is an important part of having a garden. But different plants have different needs. Plants like plenty of water, but how do you know what is too much or too little? Here are just a few helpful suggestions you may want to consider.

    3 Do's 3 Don'ts

    Water early.

    Water in the morning before it begins to get hot. It's a perfect time to water your plants. This way they are ready for the hottest parts of the day. Don't water too much.

    Although plants are usually thirsty, too much water can be harmful to their growth. If you notice the leaves are becoming yellow and falling off, it is a clear sign of too much water.

    Drain (排水) properly.

    Be sure to check the surrounding area of your plants regularly. The extra water should be drained well. Don't water late.

    This is especially important. Although not everyone will be able to do their watering in the early morning hours, try not to wait too late in the day. If you water in the afternoon when it is hot, lots of water will evaporate (蒸发)before reaching the roots. If you water in the evening, the roots will be too wet.

    Prevent insects.

    A thin, fine mist (喷雾) will prevent insects from setting on the leaves and flowers. Don't water the leaves.

    The most ideal place to begin is the root. This is where most of the growth and development takes place. In order for your plants to be strong, the roots have to be healthy.

    To really know what works well for your plants, watch them for signs of over watering or signs of not getting enough water. For more great advice on rose watering and growing roses, visit http:// www. my rose guide. com.

    Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.

    According to BBC News, there are more than 22,000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

    Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the smallest piece of junk crashed into a spaceship, it could damage it.

    To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U.S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

    To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

    Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

    "The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

    "The time to act is now. The longer we leave the problem, the bigger it will become," he says.
