Woods Hole Marine Biological Laboratory.She received her
master’s degree in zoology from Johns Hopkins University in 1932.
She worked for the U．S.Bureau of Fisheries，writing radio scripts during the

She wrote books on conservation(保护) and natural resources and edited scientific articles，but in her free time turned her government research into prose(散文)，first as an article Undersea(1937)，and then in a book，Under the Sea ­Wind(1941)．In 1952 she published her prize­winning study of the ocean，The Sea Around Us，which was followed by The Edge of the Sea in 1955.These books made up a biography(传记) of the ocean and made Carson famous as a naturalist and science writer for the public.Carson resigned in 1952 to devote herself to her writing.

Ⅲ.任务型读写
A smart card is a card that is carried with either a microprocessor and a memory chip or only a memory chip that is not programmable.The microprocessor card can add, delete, and deal with the information on the card, while a memory­chip card can only do one thing.
Smart cards, unlike magnetic stripe cards, can do many different things and hold a lot of information.In this way, they do not need to get information from a faraway place when they are used.
Today, there are several kinds of smart cards, all of which are very popular in the market: IC (Integrated Circuit) Microprocessor Cards (Chip Cards) offer a larger memory and better security than the traditional magnetic stripe cards do.Chip cards can also hold data. These cards are used for many things.Thus, chips have been the main platform for cards that hold a secure digital identity.Some examples of these cards are：
Cards that hold money.
Cards that provide safe access to a network.
Cards that allow setting stop boxes on televisions to remain safe from privacy.
Optical Memory Cards look like cards with a piece of CD on the top.Optical Memory Cards can store up to 4MB of data. But once written, the data can not be changed or removed. Thus, this type of card is good for keeping records, such as medical files, driving records or travel histories.Today, these have no processors in
them(although this is coming in the near future)．While the cards are almost as cheap as chip cards, the card readers are expensive.
