Going to sleep may seem pretty boring compared with all the fun things you do while you are awake.
But there"s a lot going on in your mind and body while you are sleeping.
Sleep, in fact, is as important to your survival as eating and drinking. Sleep improves your mood,
makes you a better athlete, and helps you remember and understand what you learned during the day.
During sleep, your temperature drops. Your heart beats slowly. A chemical that controls growth,
which is called a hormone (荷尔蒙), moves into your bloodstream. Scientists think that sleep brings back
energy and improves your immune (免疫) system. We know what happens while we"re asleep because
scientists study volunteers who sleep in laboratories. The sleepers are connected with machines that
measure brain waves, eye movements and muscle activities.
Sleep is like a school day: it"s divided into different stages (阶段). When you are awake, your brain
waves fire rapidly (迅速地). As you begin to relax and drift into the first stage of sleep, your brain produces
slower-moving waves and you lose awareness (意识) of your surroundings. As you fall into deeper sleep,
your body repairs itself from the normal wear and tear of daily life. Then, as you begin to drift back up to
a lighter sleep, your mind becomes more alert (警觉的), and your dreams begin. You are in REM sleep.
REM is the name for the rapid eye movement that happens while you are dreaming. During REM sleep,
your eyes move back and forth behind your lids, as though you were watching a movie. During other
stages, you might move in bed, but during REM sleep you"re not making any movement. That"s probably
because if you could move, your body would act out your dreams. As you get close to morning, you
spend more time in REM than in deep sleep, so you dream more. Researchers know that during REM sleep
the part of the brain that deals with learning and thinking is very active.
Getting too little sleep can affect your personality. Experts recommend that children get at least nine
hours"sleep a night. |

As a large part of land in Hawaii is rocky and mountainous, the state has little space in which to grow
crops. Some areas are also covered with hard, black lava (熔岩) on which nothing can grow. Even so,
Hawaii produces large quantities of farm products.
The volcanic (火山的) soil in the valleys and lowlands is very rich, and the warm climate makes it
possible to grow crops all year long. Rainfall is plentiful on the northern and eastern sides of each island.
Much of the land on the southern and western sides of each island receives too little rainfall for most crops
to grow well, but in many of the places where rainfall is light, wells and mountain streams supply water for
irrigation. |

| [ ] |
Ａ: geography
Ｂ: market system
Ｃ: farming conditions

margarine (人造奶油), pet food and fertillizer.
Fishermen usually freeze fish they catch at sea. Back in port, they defrost the fish, make the fish have no
bones in it and sell it as fresh fish.
Over ninety-five percent of fish caught is in the northern hemisphere. Thus, only about five percent of all
fish caught is from south of the equator.
The Japanese are the world champion fish eaters. They eat twice as much fish as the Scandinavians, and
five times as much fish as the Americans.
The Russian sturgeon (鲟鱼) is the most expensive fish in the world.
The eggs of the sturgeon are called caviar. |

What is a clone? A clone is a copy-a genetic (基因的) copy. Genes (基因) are the in-structions for
life. They 1 a cell what to do and how to do it. Genes make 2 plant or animal different and unique.
A clone has the same genes 3 the original organism (生物体).
Cloning is not new. 4 have been cloned for centuries. Many new plants are grown from cuttings
(插枝) from the original plants. One benefit of cloning is that we can make many copies of the best and
healthiest plants.
It"s 5 more difficult to clone animals than plants. In 1997 scientists succeeded in 6 a sheep.
The creation of Dolly, the Cloned sheep, caused great attention around the world in no time. Scientists had
tried to clone other animals like frogs before that, but they failed Frogs died as tadpoles (蝌蚪), never
living 7 to become adult frogs.
It may soon be 8 to clone many types of animals. Will we also 9 clone human organs (器官),
or even a whole human being? Maybe now the question is not whether we can clone humans, but 10
should we clone humans? |
