ICE-FISHING
If you drive north from Toronto for three hours, you come to Lake Nipissing. In winter, the lake becomes ice, and thousands of Canadian fishermen travel there each weekend. They build Little houses of wood on the ice and point them in bright colours. Then they sit inside to catch the fish that swim under the ice.
Bob Marvisch has come here at this time of year for twenty-five years. 'You need clothes that are light but worm: two pairs of socks and gloves, several thin sweaters and a snow suit on top. Catching the fish is easy,' he says. 'First you break the ice and make a small round hole in it. Next you take a fishing line and put some bread on it. Then you put the line through the hole and into the water. You pull the line up when the fish eat the bread. They are between ten and twenty centimetres Long. Some people Like to eat them, but when I have caught three or four fish, I prefer to have some chocolate or other snack! Today I have caught twenty- five! It's a great sport and you can meet some nice people here!
Fishermen only use the houses on Lake Nipissing in winter.
A.Right
B.Wrong
C.Doesn't say
This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. (79) A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only.
Why is this idea being discussed again? Is Britain becoming more conscious of the need for links with Europe as a result of joining the EEC(欧共体) ? Well, perhaps. The main reason, though, is that a tunnel or bridge would reach the twenty square kilometers of London' s disused dockland(船坞地). A link from London to the continent would stimulate trade and re-vitalize(使…各新有活力) the port, and would make London a main trading center in Europe. (80)With a link over the Channel, you could buy your fish and chips in England, and be able to eat them in France while they were still warm!
Which of the following statements is TRUE?
A.Swimming across the Channel takes less than four hours.
B.The idea of a Channel tunnel or bridge is a very new one.
C.It is considered to be more difficult to swim across the channel than any other means.
D.A tunnel or bridge would only reach as far as the coast.
Sharks are different from other fish. For example, other fish have skeletons made of hard bones. Sharks have skeletons made of cartilage. In addition, most fish have a special organ called a swim bladder to stop them from sinking but sharks do not. If a shark does not swim constantly, it sinks. Shark babies grow inside eggs. The baby sharks are called pups.
Most sharks eat fish. Some also eat seals and other sharks. Many people are afraid of sharks be cause of their reputation as' man-eaters'. However, there are fewer than one hundred shark attacks on humans in the world each year.
Humans are the sharks' worst enemies. Fishermen kill them because of their valuable dorsal fins. Often, they catch a shark, cut off its fin and throw it back into the sea. If a shark has no fin, it dies because it cannot swim. Scientists believe that humans kill more than one million sharks every year.
Sharks are ______.
A.humans' friends
B.man's enemies
C.the world's largest fish
D.not the same as other fish
A.My mother doesn't swim
B.My mother can't swim
C.I mother not can swim
D.My mother can swim
The fishes are about 1.5 meters long and look like carps(鲤鱼). There will be a detector intheir bodies. They canfind the sources of pollutionin the water, and then the robot fisheswilleat part of it. Unlike other robots, they don’t need to be controlled by people faraway. Therobots all have an eight-hour battery. They can “swim” in the sea freely and send backinformation to people on the beach. After their batteries die, they will return by themselves.
There are five robot fishes altogether now.Each costs about 29,000 dollars. They are partof a three-year project between engineering company BMT Group and Essex University insoutheastern England.
“We designed the fishes creatively. We hopethe robot fishes can find the changes in the seawater and report back the information,” said Professor Huof Essex University. His team isdeveloping the fishes.
What will the robots do if they find the pollution in the water?
A.They will eat part of it.
B.They will stop working.
C.They will tell people where they are.
D.They will take it out to the beach.
How longcan a battery in their bodies work each time?A.For five hours
B.For eight hours.
C.For twelve hours.
D.For one day.
How much do the five robot fishes cost altogether? A.$14, 500.
B.$29,000.
C.$145,000.
D.$1,450, 000.
Which of the following is TRUE? The robot fishes ____.A.can eat anything in the water
B.need to be controlled by people
C.are 1.5 meters long andthey look like sharks
D.cango back to the beach when the batteries run down
What can we learn from the passage? The robot fishes____.A.have worked around the world
B.can’t take out the trash in the water
C.will helppeopledetect the pollution in the water
D.help to find other fishes in the rivers, lakes and seas
