Leap Year
Leap year is a year that has 366 days instead of the usual 365．It normally occurs every four years, always on an even-numbered year．The extra day is added to our shortest month．That is the second month of the year, which in non-leap years has 28 days, two fewer that any other month． 小题1:
Leap year is also called the bissextile year． 小题2: In our calendar system there is a need for a leap year because the solar year （the time it takes the earth to go around the sun once） is actually slightly more than 365 days long．That extra day—Feb．29 every four years—helps correct the difference between our calendar and the solar calendar．
Leap year was first made part of the calendar by the ancient Roman leader Julius Caesar．His astronomers had calculated the length of the solar year to be 365 days and six hours．So Caesar declared that an extra day be added to the calendar． 小题3:
Caesar’s adjustment, however, was not entirely accurate because his astronomers’ year exceeded the true solar year by eleven minutes and fourteen seconds．By 1582, a difference of ten days had developed between the calendar year and the true solar year．To correct this error, Pope Gregory XIII ruled that every fourth year would continue to be a leap year except for century years that could not be divided evenly by 400．By this system, century years such as 1700, 1800, and 1900 were not leap years, but the year 2000 was a leap year． 小题4:
Persons born on Feb．29 celebrate their growing up a little differently from the rest of us． 小题5: But if they go strictly by the calendar, they have only one-fourth as many birthday celebrations as most people．
A．This is done every four years．
B．This is its formal, or scientific title．
C．This may seem complicated, but it works．
D．They acknowledge that they get older each year．
E．The leap year was introduced in the Julian calendar in 46 BC．
F．When you see Feb．29 on a calendar, you know that year is a leap year．
G．In a leap year, the extra day is added to the second month, giving it 29 instead of the usual 28 days |

Invention is a creative process. An open and curious mind enables one to see beyond what is known. Seeing a new possibility, a new connection or relationship can spark(引发) an invention. Inventive thinking frequently involves combining concepts or elements from different fields that would not normally be put together. Sometimes inventors skip over the boundaries between separate fields. Ways of thinking, materials, processes or tools from one field are used as no one else has imagined in a different field.
Play can lead to invention. Childhood curiosity like playing in a sand box, imagination can develop one’s play nature—an inner need according to Carl Jung. Inventors feel the need to play with things that interest them, and to explore, and this internal drive brings about interesting creations.
Inventing can also be an obsession(痴迷). Inventors often imagine a new idea, seeing it in their mind’s eye. New ideas can arise when the conscious mind turns away from the subject or problem; or when the focus is on something else; or even while relaxing or sleeping. An unusual idea may come all of a sudden! For example, after years of working to figure out the general theory of relativity, the solution came to Einstein suddenly in a dream “like a giant die making an unforgettable impress, a huge map of the universe summarized itself in one clear vision”.
Invention can also be accidental. Insight(洞察力) is also an important element of invention. It may begin with questions or doubt. It may begin by recognizing something unusual. It may be useful and it could open a new way for exploration. For example, the odd metallic color of plastic made by accidentally adding too much catalyst(催化剂) led scientists to explore its metal-like properties(性能). They then invented electrically conductive plastic and light emitting(散发) plastic—an invention that won the Nobel Prize in 2000 and has led to new kind of lighting, display screens, wallpaper and much more.

小题1:-----------------------
When we speak of a basic human need we mean something necessary to life, something we cannot do without. Food is a basic human need. Without it we would starve to death. Whether in primitive(原始的)countries or in more advanced societies, man’s food needs are the same. 小题2:
But primitive people eat only the food which can be grown near their homes, whereas people in more advanced societies eat food which is often grown many thousands of miles away from their homes. Primitive people are satisfied with less kinds of food, therefore we can say people’s wants are different although their needs are the same.
小题3:Clothing is necessary to regulate (调节) the heat of our bodies. In different climates and in different seasons we need more or less clothes. We also dress differently for other reasons. 小题4:
Shelter, the third of our needs, depends on climate, the skill of the builders, one’s social position, and the material which can be used. 小题5:The three-bed-roomed house of the average family would not be grand enough for a very rich family, but a modern house with many of the material comforts were denied to the kings and queens in the past.| A．Food, Clothing and Shelter. | | B．Human Needs | | C．We always change our style of clothing for different occasions, such as work, sports, parties. | | D．We all need food to live a healthy life. |

Perhaps I am courageous, but that’s because I’ve had some inspiring teachers. I’ll tell you about one of them. Many years ago, when I worked 1 a volunteer at Stanford Hospital, I got to know a little girl named Liza 2 was suffering from a rare and serious disease, Her only chance of 3 (recover) appeared to be a blood transfusion (输血) from 4 five-year-old brother, who 5 (survive) the same disease and developed the antibodies needed to combat the illness. The doctor explained the situation to her little brother, and asked the boy 6 he would be willing to give his blood to his sister. I saw him hesitate for a moment 7 taking a deep breath and saying, "Yes, I’ll do it if it will save Liza."
As the transfusion progressed, he lay in a bed next to his sister, 8 (smile). But then his face grew pale and his smile faded. He looked at the doctor and asked with 9 trembling voice, "Will I start to die fight away?"
Being young, the boy had misunderstood the doctor. He thought he was going to have to give her 10 his blood. |
