Japanese young today study English for six years at junior and senior high school, but very little
can speak it by the time they graduate. If the Japanese want to acquire practice oral skills, they
have to do a conscientious effort by themselves as going abroad or taking English conversation
classes in their private country. In Japan, grammar is emphasized too much at Japanese high
school, and there is no balance with the speaking language. People study English mainly for
passing exams. They're so tied to grammar teaching in the textbooks that they find spoken
English naturally very difficult. They should consider English more as a means of communication
than of a science.

Scientists have established that influenza viruses took from man can cause the disease in
animals. On addition, man can catch the disease from animals. In fact, a great number in wild
birds seem to carry the virus without show any evidences of illness. Some scientists conclude
that a large family of influenza viruses may have evolved in the bird kingdom, a group that has
been in the earth 100 million years and is able to carry the virus without contracting the disease.
There is even convincing evidence showing that virus strains are transmitted from place on place
and from continent to continent by migrating birds. It is known which two influenza viruses can
recombine when both are present in an animal at the same time. The result of such
recombination is a great vary of strains containing different H and N spikes. This raises the
possibility that a human influenza virus can recombine with an influenza virus from a lower
animal to produce an entirely new spike. Research is underway to determine if that is the way
that major new strains come into being. Other possibility is that two animals influenza strains
may recombine in a pig, for example, to produce a new strains which is transmitted to man.

English, but it is the international language. There is no way changing that now.

The word laser was coined as an acronym to Light Amplification by the stimulated
Emission of Radiation. Ordinary light, from the Sun or a light bulb, is emitted spontaneously,
when atoms or molecules get rid of the excess energy by themselves, without any outside
intervention. Stimulated emission is difference because it occurs when an atom or molecule
holding onto excess energy has been stimulated to emit it as light.
Albert Einstein was the first suggest the existence of stimulated emission in a paper
published in 1917. However, for many years, physicists thought that atoms and molecules always
were much more likely to emit light spontaneously and that stimulated emission thus always
would be much weak. It was not until after the Second World War that physicists began trying to
make stimulated emission dominate. They sought ways by which one atom or molecule could
stimulate many other to emit light, amplifying it to much higher powers.
The first to succeed was Charles H. Townes, then at Columbia University in New York.
Instead of working with light, however, he works with microwaves, which have a much longer
wavelength, and built a device he called a “maser”, for Microwave Amplification by the
Stimulated Emission of Radiation. Although he thought of the key idea in 1951, the first maser
was not completed until a couple of years laterly. Before long, many other physicists were
building masers and trying to discover to produce stimulated emission at even shorter

At the age of sixty-five, Laura Ingalls Wilder began writing a sery of novels for young people
based in her early experiences on the American frontier. Born in the state of Wiscosin in 1867,
she or her family were rugged pioneers. Seeking better farm land, they went by covered wagon
to Missouri in 1869, then on to Kansas the next year, return to Wisconsin in 1871, and travelling
on to Minnesota and Lowa before settling permanently in South Dakota in 1879. Because off this
continuing moving, Wilder's early education took place sporadically in a succession of one-room
schools. From age thirteen to sixteen she attended a school more regularly although she never
graduated.
At the age of eighteen, she married Almanzo James Wilder. They bought the small farm in the
Ozarks, where they remained for the rest of their live. Their only daughter, Rose, who had
become a nationally known journalist, encouraged her mother to write. Serving like agent and
editor, Rose negotiated with Harper's to publish her mother's first book,
Little House on the Big
Woods.
Seven more books followed, each chronicling her early life on the plains. Written from
the perspective of a child, they have remained popular to young readers from many nations.
Twenty years after her death in 1957, more than 20 million copies had been sold, and they had
been translated into fourteen languages. In 1974, a weekly television series, "
