Big ocean(海洋)fish have almost disappeared from the world since the start of business fishing in the 1950’s．The scientists found that the number of large fish has dropped by 90 percent in the past fifty years．The study took ten years．The researchers collected records from fishing business and governments around the world．The magazine Nature published the findings．
The scientists say the common way called longline fishing is especially harmful to large fish．This way includes many fishing lines that are connected to one boat．If these lines are joined together，they can reach one hundred kilometers．They hold thousands of sharp metal hooks to catch fish．Longline fishing is especially common in the Japanese fishing industry．Records show that Japanese boats used to catch about ten fish for every hundred hooks．The study says longline fishing boats now might catch one fish per hundred hooks．
The scientists say business fishing can destroy groups of fish much faster than in the past．The study suggests that large fish can disappear almost completely from new fishing areas within ten to fifteen years．Ocean life system could be destroyed．
It’s not the only worry that the number of large fish is becoming smaller and smaller．What’s worse．they are smaller in size than their ancestors(祖先)．
小題1:The magazine Nature published the findings．The word“published”here means________．
A．發(fā)表B．發(fā)現(xiàn)C．研究D．調(diào)查

A new term has begun. Teachers are  41  about the fact that new students are not easy to deal with. They like to bring cell phones and MP3 players to school. What is worse , some students even use cell phones  42  out-of-class matters in class, or sometimes just for fun. Some  43  students listen to MP3 players when they are having a lesson that they are not interested in.
Are these new students really that  44 ? “Yes.” Says Delaney Kirk, a professor（教授） at Drake University. But she adds it’s not their fault. 45 , the teachers should be blamed(責備). Mrs Kirk first began thinking about students’ manners six years ago. “I had my first class in which students were sleeping or talking to each other. It seemed that learning well had nothing to do with them.” She says. “At first, I got worried about this.” But then I said to  46 , “You’re giving lessons, and you need to manage this kind of situation. These students need to know more about manners. It’s time to help them develop some good  47 . They shouldn’t waste time doing nothing when they are young. Sooner or later, they may regret(后悔) the time they  48 .”
Mrs Kirk also makes a list of suggestions to help teachers better manage（駕馭） their classes. The following are among her suggestions:
On the first day of class, tell students how they will benefit(受益)by taking the class and the importance  49  listening carefully in class.
Do not allow them to bring cellphones or MP3 players to the class at all.
Tell them 50 to use cell phones or MP3 players properly(適當?shù)?..

Have you ever seen people building houses? To build a house , you need workers. They use their hands , tools(工具) and machines to put things together. Building the ISS（國際太空站） is the same. The difference is that the workers are astronauts. They walk in space and use robots’ arms and hands to do their work.
In the space station ,astronauts are comfortable. The temperature there is about 21℃.But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(陰暗處)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes----spacesuits.
Spacesuits also keep astronauts safe from flying rubbish(垃圾)in space.Each time people go into space , they leave rubbish there. So astronauts should be careful because there’s a lot of rubbish, some rubbish goes many times as fast as a plane !
Space walking is not easy , and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900man-hour of work.

Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no medicine, either.
Life today brings new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and we become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is very thick. People cannot see the sky clearly.
Many countries are making rules to fight against pollution. Factories now must clean their water before they throw it away. And they mustn’t let dirty smoke go into the air.
There are many things we can do to fight against pollution. We should put waste things in dustbins and do not throw them on the ground. We should go to work by bike or on foot instead of taking a car or a bus. If there are fewer people driving, there will be less pollution.
Rules are not enough. We should do our best to fight against pollution.
