Why salmon will newer get lost

    When you're packing for an adventure, what's the most important thing you'll need? If you don't want to get lost, you' need a map. Or better yet, a GPS. What about other animals? How do they know where they're going?

    While humans depend on technology to travel, some animals have something far more advanced. Researchers, mainly from Oregon State University, US, found that Chinook salmon have a "built in GPS" of the Earth's magnetic field(磁场). This means as soon as they are born they are able to direct themselves in the ocean. It acts like a big map inside their brain.

    Scientists placed some baby salmon into a big swimming pool. To simulate the Earth's magnetic field, they put magnetic coils(线圈) all around the pool. Then, by changing the direction of the coils, the salmon began to change their own direction. They started to face in the direction of their ocean feeding area. This is a safe place in the ocean where salmon can find food to eat. When the scientists changed the coils to the opposite side, the salmon also turned in the opposite direction. Just by using their "built-in GPS", the salmon were able to figure out the direction of their feeding area.

    How did Chinook salmon get their "built in GPS"? The scientists believe that their navigation(导航) skills came through evolution(进化). The fish that were able to reach the feeding area lived longer. Then they could pass on their navigation skills to their babies. So if you're ever lost and in need of some help, maybe you should ask a salmon to point you in the right direction!

A、have their own magnetic field B、learn direction from their mother C、can find directions in the ocean D、have the same navigation skills as humans
(2)、What does the underlined word "It" in paragraph 2 refer to?

(3)、What does the underlined word "simulate" in paragraph 3 probably mean?

(4)、The passage mainly talks about       .
A、the wide use of the GPS B、the evolution of the Chinook salmon C、the research of ocean life D、Chinook salmon and their built in GPS
(5)、The passage is probably from             .
A、a novel B、a science report C、an advertisement D、a guide book

    How green are you?Do you know how to be green?

    We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

    Reduce

    Reduce means" use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary﹣or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

    Reuse

    Reuse means" use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup of a paper bag. It's better to use a china cup and a lunch box because you can use them again.

    Recycle

    Recycle means" change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

    So please remember these three words: reduce, reuse and recycle.

第一篇

①Hobbies are great ways to spend your time. Some hobbies can even change the way you see the world. Let's take painting as an example.

②When you're painting, you should pay attention to the colour. Think for a moment about what colour clouds are. Did you think white? Take a closer look at them next time. Clouds are mostly white, but the colours also include black, grey, yellow, pink and even blue. It depends on so many factors(因素), like what time of day you are looking at them, the kind of clouds or the angle (角度) you're looking at them. At sunset, you'll see many colours in clouds but you won't see at mid-afternoon.

③Painting is also a great way to notice shapes(形状). One of the easiest ways to paint faces or objects is to break them down into their relative shapes and combine them together. Everything in the world can be broken down into things like circles, squares and triangles. It's like putting pieces of a puzzle together as you're creating your painting.

④If you take up painting, you'll see more colours and shapes in the world. You'll notice small influences(影响) of colours in the evening and will be able to break anything down into their relative shapes. So everything is more beautiful than ever. In this way, hobbies introduce us to a new world.

Inventions are very important and they can easily change our life. The followings are some great inventions. 

 

The television was invented in 1925. As time passed,more and more people were able to buy the television. It is a popular invention,but it is also bad for your eyes. People spend almost 4~8 hours in front of a TV while they spend less than 2 hours staying with their family. 

The plane was invented in 1903. It is a very popular way of going out either for travelling or business. Over 3,000,000 people take a plane every day. It is very convenient for us. And it makes our trip faster and more comfortable. But the biggest problem led by the planes is the air pollution. 

 

Credit cards were started in 1915. They allow people to buy things first and pay for them later. What's more,you don't have to carry lots of money around. You can know what you have bought by credit cards. However,you may not know how much money you have spent until you get your bill. This might put many young people and families into an economic crisis(经济危机). 

The pacemaker(心脏起搏器) began to be used in 1932. It saves many people's lives. It was an invention that was designed to give the heart small "shocks" and make it work again. The only disadvantage(缺点) for most people is that it costs a lot of money. Getting one can cost from 16,500 yuan to 35

 阅读短文 从下面每题的A、B、C、D四个选项中选出最佳选项。

①What will you do if you see a cockroaeh(蟑螂) ? Quite a few people are very afraid of it, so they may shout for help or try to kill it. Next time you see it, you may need to think twice before killing it.

②There were cockroaches on the earth long ago, and many people believe that they will still be here long after all the people leave it. Cockroaches are small in size, and they are good at climbing and jumping. A cockroach can live for about a week without a head. These make them great helpers during the search and rescue missions(搜救任务).

③Alper heads up led a scientist team at North Carolina Stage University. "I joined the search and rescue missions in Turkey in 1999, "he said. "One of the most difficult problems was to find where the living people were. We needed to find them in a short time, but there was no useful way to help us at that time. "So Alper and his team had the idea of turning cockroaches into special robots.

④Scientists put a small sensor(传感器) and a smart camera on a cockroach's back. Cockroaches climb everywhere with them, With a sensor and the camera, cockroaches can tell people from other things, and then find where the missing people are. In this way, more people can be saved in time.

⑤All in all, the scientists hope these special cockroach robots will be used for more work over the next five years. "We never thought we would see the day, but here we are!"a scientist said.
