Pheromones are substances that serve as chemical signals between members of the same sp

Pheromones are substances that serve as chemical signals between members of the

same species. They are secreted to the outside of the body and cause other individuals

of the species to have specific reactions. Pheromones, which are sometimes called

line "social hormones," affect a group of individuals somewhat like hormones do an individual

(5) animal. Pheromones are the predominant medium of communication among insects

(but rarely the sole method). Some species have simple pheromone systems and produce

only a few pheromones, but others produce many with various functions. Pheromone

systems are the most complex in some of the so-called social insects, insects that live

in organized groups.

(10) Chemical communication differs from that by sight or sound in several ways.

Transmission is relatively slow (the chemical signals are usually airborne), but the

signal can be persistent, depending upon the volatility of the chemical, and is sometimes

effective over a very long range. Localization of the signal is generally poorer than

localization of a sound or visual stimulus and is usually effected by the animal's moving

(15) upwind in response to the stimulus. The ability to modulate a chemical signal is limited,

compared with communication by visual or acoustic means, but some pheromones may

convey different meanings and consequently result in different behavioral or physiological

responses, depending on their concentration or when presented in combination. The

modulation of chemical signals occurs via the elaboration of the number of exocrine

(20) glands that produce pheromones. Some species, such as ants, seem to be very articulate

creatures, but their medium of communication is difficult for humans to study and

appreciate because of our own olfactory, insensitivity and the technological difficulties

in detecting and analyzing these pheromones.

Pheromones play numerous roles in the activities of insects, They may act as alarm

(25) substances, play a role in individual and group recognition, serve as attractants between

sexes, mediate the formation of aggregations, identify foraging trails, and be involved in

caste determination. For example, pheromones involved in caste determination include

the "queen substance" produced by queen honey bees. Aphids, which are particularly

vulnerable to predators because of their gregarious habits and sedentary nature, secrete

an alarm pheromone when attacked that causes nearby aphids to respond by moving away.

What does the passage mainly discuss？

A．How insects use pheromones to communicate

B．How pheromones are produced by insects

C．Why analyzing insect pheromones is difficult

D．The different uses of pheromones among various insect species

Supermarket

Supermarket is a type of retailing institution that has a moderately broad product assortment spanning groceries and some nonfood lines, that ordinarily emphasizes price in either an offensive or defensive way. As a method, supermarket retailing features several related product lines, a high degree of self-service, largely centralized checkout, and competitive prices. The supermarket approach to retailing is used to sell various kinds of merchandise, (8) .

The term supermarket usually refers to an institution in the grocery retailing field. Most supermarkets emphasize price. Some use price offensively by featuring low prices in order to attract customers. Other supermarkets use price more defensively by relying on leader pricing to avoid a price disadvantage. Since supermarkets typically have very thin gross margins, they need high levels of inventory turnover to achieve satisfactory returns on invested capital.

Supermarkets originated in-the early 1930s. They were established by independents (9) . Supermarkets were an immediate success, and the innovation was soon adopted by chain stores. In recent decades supermarkets have added various nonfood lines to provide customers with one-stop shopping convenience and to improve overall gross margins.

Today stores using the supermarket method of retailing are dominant in grocery retailing. However, different names are used to distinguish these institutions (10) .

A superstore is a larger version of the supermarket. It offers more grocery and nonfood items (11) . Many supermarket chains are emphasizing superstores in their new construction.

Combination stores are usually even larger than superstore. They, too, offer more groceries and nonfoods than a supermarket but also most product lines found in a large drugstore. Some combination stores are joint ventures between supermarkets and drug chains such as Kroger and Sav-on.

For many years the supermarket has been under attack from numerous competitors. For example, a grocery shopper can choose among not only many brands of supermarkets but also various types of institutions (ware house stores, gourmet shops, meat and fish markets, and convenience stores). Supermarkets have reacted to competitive pressures (12) : Some cut costs and stressed low prices by offering more private brands and generic products and few customer services. Others expanded their store size and assortments by adding more nonfood lines (especially products found in drugstores), groceries attuned to a particular market area (foods that appeal to a specific ethnic group, for example), and various service departments (including video rentals, restaurants, delicatessens, financial institutions, and pharmacies).

A including building materials, office products, and, of course, groceries

B attracting more customers with their low prices

C primarily in either of two ways

D to compete with grocery chains

E a type of retailing institution

F by size and assortment

G than a conventional supermarket does
