However, at least one kind of pig can be useful in saving money．“ 4 ”You can buy a small container shaped like a pig．It has a hole where you can put money into it．Hogs are very large animals．If you say you ate high on the hog during a holiday, it means you ate very good or costly food．If you went whole hog on your trip, it means you did everything possible to have fun．But you should never go hog-wild at any time because that means behaving badly． 5 And a road hog is a driver who uses more than his share of the road．Such a driver increases dangers for other drivers．

Two brightly colored butterflies have just flown by．They seems to be exactly alike, but actually one is a little larger than the other． 1 The smaller one has a wingspread of less than three inches and also a black line on its back wings．
At first sight, it is hard to tell them apart．Would you guess from this that they are different-sized butterflies of the same species? 2 If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families．
The larger insect is the monarch butterfly(黑脉金斑蝶)．As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell． 3 Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone．
4 Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it．The viceroy's similarity to the monarch gives it some protection from its enemies and helps it survive．
There are other pairs of look-alike butterflies, bees and moths．In each case, one either has a disagreeable taste or smell, or can give a painful sting(叮咬)．The larger is called the model． 5 (词数206)
A．The smaller insect is the viceroy(副王峡蝶), which feeds on the leaves of trees．
B．The larger insect has a wingspread(翼长)of up to four inches．
C．The bright coloring of the monarch acts as a warning sign to its enemy．
D．Birds protect their babies from eating such dangerous enemies．
E．The insect that imitates this model for protection is called the mimic(保护色)．
F．Or that they are different species of butterflies but close relatives belonging to the same family?
G．Do you like this kind of special species?
