The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer(层)just under the surface.The outside dead layers wear off(磨损)all the time,with new ones replacing them,and the body forms a totally new skin every three weeks.
The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(细菌)can’t get in through the skin unless it is damaged.
If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收缩),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.
When it is hot,the blood vessels expand(扩大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.
If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神经)in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.
The colour of the skin depends on special colour cells(细胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(晒黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.
【小题1】Which of the following statements is NOT true?

A．Our hair and nails are dead like the surface of the skin.

B．There is skin all over our body.

C．The skin of our bodies will be completely different in three weeks.

D．The surface of the skin is made of a living layer.

【小题2】The second paragraph mainly tells us about______.

A．the functions of the skin

B．the information from the outside

C．the water in the body

D．the temperature of the body

【小题3】Bacteria will get in through the skin______.

A．when one’s skin is numb

B．when one is ill

C．when the skin is cut

D．when the sweat glands produce more sweat

【小题4】When the weather is cold,the skin will contract in order to______.

A．allow more blood near	B．make the skin look blue
C．keep warmth	D．help the body lose heat

【小题5】The colour of the skin is determined by______.

A．the rays of the strong sun	B．colour cells
C．top layers of the skin	D．vitamin D

Babies are not just passing idle time when they stare goggle-eyed at the television—they are actually learning about the world, U.S. researchers said. Parents may want t limit what their babies see on television , based on the study, said Donna Mumme, assistant professor of psychology at Tufts University in Boston, who led the research. “Children as young as 12 months are making decisions based n the emotional(情感的)reactions of adults around them,” Mumme said in a statement. “It turns out they can also use emotional information they pick up from television. This means that adults might want to think twice before they speak in a loud and harsh voice or let a baby see television programs meant for information about the world. A mother urging her baby to eat some “yummy” soup on a brother crying in fear when a dog approaches can influence a baby’s reaction. Mumme’s team tested babies to determine. If television has the same influence, showing actors reacting on a videotape to objects such as red spiral letter holder, a blue humpy ball, and a yellow garden hose attachment. Babies aged 10 months or 12 months were later given the same objects to play with. Ten-month-olds did not seem to e influenced by the video buy the 1-year-olds were. When the actors acted neutrally or positively to an object, the babies happily played with them. But if the actor had seemed afraid or disgusted, the babies would avoid the object.
72．Psychology is the study of .
A．human’s society and its growth
B．human’s hopes had dreams
C．human’s mind and behaviors
D．human’s languages and cultures

A．Small babies should not be allowed to watch television programs.
B．Adults need to think twice before they act in front of small babies.
C．TV programs provide small babies with all the information they need.
D．One-year-olds can be emotionally influenced by TV programs.
74．Mumme reached his conclusion by .
A．measuring the time babies spent in front of TV.
B．making TV programs and advertisements for kids.
C．showing actors how to react to blue bumpy balls
D．observing small babies’ reactions to TV programs
75．Which of the following may the study lead to according to the researchers?
A．Parents may want to limit what their babies see on television.
B．Actors may try to behave themselves well in front of babies.

One warm day when I was walking in my backyard, I saw a pinecone(松球) on the ground. I picked it up, and some seeds fell out of it. Those seeds would be a tasty treat for a squirrel (松鼠).
I realized that pinecones were not always open like this one. Sometimes cones were tightly closed. I decided to find out why.
I gathered pinecones from my backyard. I watched them for over a year. Here’s what I learned.
Pinecones open and close slowly as the weather changes. When it’s cold or wet, cones are tightly closed. This protects the seeds inside from rain and snow.
When the weather becomes warm and dry, pinecones open. On a hot day, you might even hear the sound of cones popping open. The seeds inside may then fall to the ground. The wind may blow the seeds to places where they can grow into new pine trees. A seed has a better chance of taking root and growing when the weather is warm.
“Pine seeds are an important source of food for many animals,” says Monty Maldonado. He is a pinecone expert with the United States Forest Service. He says squirrels depend on pinecone seeds for most of their meals. They spend lots of time gathering and storing the cones. Maldonado says some animals eat only the seeds from a pinecone. But red squirrels and gray squirrels will eat the whole thing.
Small animals aren’t the only creatures that eat pine seeds. Maldonado says big grizzly bears (灰熊) and people eat them, too.
Seeds inside a pinecone are important for the growth of new trees and as food for animals. It is the pinecone’s job to protect them. So take note of the pinecones you see on the ground. They hold treasures inside.
45．According to the passage, when it is rainy, cones          .
A．are open   B．are usually shut       C．grow quickly    D．stop growing
46．According to Monty Maldonado,        .
A．not all squirrels eat the whole pinecone
B．pine seeds are difficult to find for many animals
C．people in the forest are sometimes attacked by grizzly bears
D．most small animals depend on pinecone seeds for their meals
47．We can learn from the passage that on sunny days         .
A．seeds may fall out of the cones
B．squirrels stay still in their nests
C．it’s difficult for a seed to take root
D．the wind will put the pine trees in danger
48．In the last paragraph, the author points out that         .
A．more and more new trees need to be planted in future
B．people should be responsible for protecting animals
C．people should be careful not to damage the pinecones
D．squirrels now have few seeds to feed themselves
49．Which of the following is TRUE according to the passage?
A．The author learned why pinecones are not always open in the forest.
B．The author gathered pinecones and observed them for a month.
C．The author is fond of gathering and storing the cones.
D．Pine trees are precious to animals and people.
