题目内容
Can you imagine a catfish bigger than a boy ? There are more than 1,000 kinds of catfish; 28 species are found in the United States’ lakes and rivers. This huge family has some mighty strange members. Let’s meet a few.
Walking catfish. Nature’s feisty little catfish, found in southern Florida, has an extra lung for breathing on dry land. When its swimming hole dries up, the walking catfish waddles on stiff forward fins in search of another lake or stream. If an enemy attacks, the fish flares (展开) its top and front fins and leaps at the attacker to scare it off.
Armored catfish. This catfish has heavy, bony plates protecting its body. The shell makes the fish difficult to bone. To cook it, throw the fish whole into a fire. When it is done, break it open for eating. Some armored catfish are found in Florida, but the 100-pounders live in South America.
Rounding out the family of strange catfish are talking catfish, which make growing sound when you pull them from the water; climbing catfish, which move quickly up shore brush in search of food; electric catfish, which can deliver a mild shock; and blind catfish, which settle in the inky blackness of underwater caves. Blind catfish find food through taste buds in their eight whiskers (须).
Most catfish have four whiskers on the upper jaw and four on the lower jaw. Sensory holes on these whiskers help the fish smell and taste food even in the muddiest of water. The United States does not have catfish anywhere near the size of those in South America. But in some large U.S. rivers, blue and flathead catties do top 100 pounds.
Most of the catfish you are likely to catch will be much smaller, about frying pan size. When you catch one, remember that the top fin and the forward fins have poison glands(腺) at their bases. They can give you painful wounds,(…)

Talking on a mobile phone is expensive, so a lot of people send text messages. Text messages are much cheaper than talking on a mobile phone, and you can make it cheaper by making the words shorter. You can do this by taking out “unimportant” letters in the words and using numbers instead of words (2 =" to," 3 =" free," 4 =" for," 8 =" ate," so h8 =" hate," etc.). You can also keep away from using punctuation (标点). Here is an example: Do U wnt 2 g 2 th cnma tnite (Do you want to go to the cinema tonight?)
What do you think these text messages mean?
Whr hv U bn? Iv bn wtng hrs fr a cll.

Mobile phone users have developed a group of symbols (符号) to show how they feel. They are called emoticons, and there are some examples below. To read an emoticon, you have to look at it sideways. For example, if you say something in a text message that is a joke, you can follow it with a smiling face. Like this: Why didt u call me? I’m so sad. (
Here are some others. Can you think of text messages where you could use them?
) laughing ( sad < really sad
Ⅴ shouting |·| asleep :0 shocked
