It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself: it is a part of a system (體系) in which all forms of life are joined together. If we change one part of the natural order, this will in its turn almost certainly bring about changes in some other part.
The cutting down of forests reduces the supply of oxygen. The killing of weeds and insects by chemicals leads to the wide spread poisoning of animals and birds. The throwing of waste products into the ocean harm to life in the sea, while waste gases change the chemical balance of the atmosphere.
And so we could go on, adding more examples, until in despair (絕望) we might feel like giving up the struggle to control and keep within limits these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but not so clever at looking far ahead, or at thinking about what the future results of his action might be.
【小題1】The first paragraph mainly tells us that __________.

A．it is very important to protect forests

B．there are some living things which can exist all by themselves without change

C．a(chǎn)ll forms of life belong to a system in which all the part can be changed for one another

D．we cannot change one form of life or matter without disturbing (擾亂) the balance of nature

Before going outside in the morning, many of us check a window thermometer(溫度計)for the temperature. This helps us decide what to wear. _______71______ . We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.

Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.

Both systems use the freezing and boiling points of water as their guide._____72_______ .

The most common kind of thermometer is made with mercury(水銀)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收縮). That is why on hot days the mercury line is high in the glass tube.______73______.

First. Take a clear glass juice bottle that has a cap; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.

_______74____________.

Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.

_______75___________.

As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

A. We use and depend on thermometers to measure the temperature of many other things in our daily lives.

B. Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.

C. Now that you know this rule you can make a thermometer of your own that will work.

D. The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.

E. They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.

F. Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal(把..粘住) them together.

G. People use thermometers which are made by themselves when travelling around the world.

The computer keyboard helped kill shorthand—a system of rapid handwriting, and now it’s threatening to finish off handwriting as a whole. When handwritten essays were introduced on the SAT exams for the class of 2012, just 15% of the most1.5 million students wrote their answers in cursive(草寫字母). The rest? Block letters.

And those college hopefuls are just the first edge of a wave of US students who no longer get much handwriting instructions in the primary grades, frequently 10 minutes a day or less. As a result, more and more students struggle to read and write cursive.

At Keene Mill Elementary School in Springfield, all their poems and stories are typed. Children in Fairfax County schools are taught keyboarding beginning in kindergarten. Older students who never mastered handwriting say it doesn’t affect their grades.

There are those who say the culture is at a crossing, turning from the written word to the typed one. If handwriting becomes a lost form of communication, does it matter?

It was at University Virginia that researchers recently discovered a previously unknown poem by Robert, written in his unique script. Handwritten documents are more valuable to researchers, historians say, because their authenticity(真實性) can be confirmed. Students also find them more fascinating.

The loss of handwriting also may be  a cognitive(認知的) opportunity missed. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better—a lifelong benefit.

It doesn’t take much to teach better handwriting skills. At some schools in Prince George’s County, elementary school students use a program called Handwriting Without Tears for 15 minutes a day. They learn the correct formation of manuscript letters through second grade, and cursive letters in third grade.

There are always going to be some kids who struggle with handwriting because of their particular neurological(神經(jīng)系統(tǒng)的) writing, learning issues or poor motor skills. Educators often point to this factor in support of keyboarding.

A. the schools are responsible for the loss of handwriting

B. the loss of handwriting is a cognitive opportunity missed

C. it doesn’t take much to teach better handwriting skills

D. the culture is turning from the written word to the typed one

Beginning college is exciting: new ideas to explore, new challenges to be met and many decisions to be made．Your future begins here.
However, you will find college life is different from your previous school environment．Many of us can be easily overwhelmed（壓垮）by the details of running a well-balanced life．While some of us may have the know-how, I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you.
The following you may find of use about life on campus.
●Plan well．There are so many new things to do at a new college or university．Give yourself time to make new friends and become familiar with the campus, but don’t forget why you are there．Give some time for social activities and manage your time wisely.
●If you don’t have a “system” for planning your time now (like a day timer, a computer date book), get one．Most of all, don’t depend on your memory.
●Don’t miss the guidelines．The restrictions, rules and regulations of all kinds can usually be found in your student handbook．Consider them well-balanced food for thought．What dates are important? What pieces of paper need to be handed in? What can/ can’t you do in class? What can/ can’t you do in your student residence（住處）? Who has right for what? What do you need to complete to graduate?
●Write the word “STUDY” on the walls of our bedroom and bathroom, and maybe it will help to write it on a piece of paper and stick it on the telephone, TV and the kitchen table．Consider this—you are paying thousands of dollars for your courses．You pay every time you have to repeat or replace a course.
●Build your identity．This is the time for you to decide what to do and what not to do．Take as much time as you need to explore new ideas．Do not be afraid of the beyond．This is learning to make good choices.

Ever since humans have lived on the earth, they have made use of various forms of communication．Generally, this expression of thoughts and feelings has been in the form of oral speech．When there is a language barrier(障礙), communication is completed through sign language in which motions stand for letters, words, and ideas．Tourists and the people unable to hear or speak have had to turn to this form of expression．Many of these symbols of whole words are very lively and exact and can be used internationally; spelling, however, cannot．

Body language sends ideas or thoughts by certain actions, either meaningfully or not．A wink（眨眼）can be a way of showing that the party is only joking．A nod means agreement, while shaking the head indicates disagreement．

Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags, Morse code, and smoke signals．Road maps and picture signs also guide and warn people．While language is the most common form of communication, other systems and techniques also express human thoughts and feelings．
