     Not long ago, Richard Denniston found himself suffering the same pain that millions of other pet owners
have faced. His little dog had a brain tumor (腫塊) and would soon die. Like others who faced the problem
before him, Denniston just wanted to end his pet's suffering.
    However, he took one step further.
    Denniston, an expert who studies animals collected a tiny skin sample (小塊皮膚樣本) from the dog and
took it to his laboratory at Louisiana State University. Denniston started a new technology. Denniston's
company will save pet's DNA for US ＄500, plus a monthly storage fee (保存費) of US ＄10, until cloning
becomes a reality (現實).
    "It could happen soon if everything went on well," says Mark Westhusin, a professor leading a dog
cloning team. Most experts put successful dog cloning a year to five years down the road. The cost may
be expensive at first, but it would drop at last.
     Since Dolly the Sheep was first cloned in 1996, cattle, goats, mice and monkeys have been cloned in labs.
Pets are likely to be next.

1. After his pet died, Richard Denniston ______.

A. did something more than the ordinary pet owners
B. did as other pet owners
C. did nothing but feel very sad
D. could not help feeling lonely without his dear pet

A. work on DNA
B. clone dogs
C. clone sheep
D. clone human

4. Most experts believe people will be able to clone a dog ______.

A. in a year
B. in two years
C. in six years
D. between one to five years

     No air means death. Although we can not see it, there is air round us. So air is everywhere and it gives
life to every living thing. Without it we can not live. Bad air makes people ill. We must have fresh air to
keep us in good health.
     In the city there are a great many people and there are too many cars running on the roads. The gas
which the cars spread out is full of poison. Everyday we breathe it in again and again. This makes us feel
sick. Therefore people should go out of door as much as they can.
     Besides so many cars, there are many factories too. From the chimneys of these factories, we get the
smoke usually in black or grey colour. This kind of smoke, when it mixes the air, is dangerous to our health.
It is because smoke contains many small poisonous solids and gases. So in order to keep us healthy we have
to go out to the countryside to breathe more fresh air. Or we can go up hills to get more fresh air.

No one can change the weather. But if we read correctly the signs around us, we can tell how
the weather will be. This way of telling of what the weather will be like on the following day or two is
called weather forecasting. For many centuries and in all countries, people have studied the weather
and tried to make weather forecasting. Rings around the sun are a sigh of coming rain. Many people
feel in their bones the coming of wet weather, their joints ache. Some birds fly high if fine weather is
coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because
of the insects which they are hunting that they fly low. If you see a rainbow during rainy weather, this
is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars
twinkle clearly at night, then fine weather will continues. If a fog appears in the morning just above a
river, then the day will be warm. If the sunset is mostly red in color, then the following day will be
warm. If a rainbow appears in the morning, rainy weather will probably come. Most of the above
saying have been made by the people who have used their eyes and brains to make weather
forecasting.

A. is a sign of coming rain

     No one wants to look silly or do the wrong thing at a new job. It is important to make a good impression
from the very first day. You will face new people. You will be in a new place. It may be difficult to know
what to do. We have some tips for you to make it through the first day at a new job:
     # First impression can last forever. Make sure you make a good impression. Before your first day, find
out if your new job has a dress code (rules about what you can wear to work). If so, be sure to follow it.
Remember always to be neat and clean.
    # Get to work on time. Give yourself an extra 15 minutes to make sure you arrive on time.
    # Pay attention to introductions. One of the first that your supervisor may do is to introduce you to co-
workers (同事). These co-workers will be important to you. They are the ones that will answer your questions
when the boss is not around.
     # Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If he or
she has not told you your duties, ask for a list. Set daily and weekly goals for yourself.
     # Never be the first to leave. Observe (觀察) what your co-workers do around quitting time. It doesn't look
good for you to be eager (急切) to leave.
