When do you think of a forest, what do you see? Just trees Or do you see many other things, such as singing birds, colorful plants and wild flowers?
The forest is a whole world of its own. It is full of many different living things (生物). But even thoughthey are all different, they have one thing in common: they all need each other in order to live on. 
The trees feed the forest "people" by making food in their leaves; by using sunlight to join water and minerals(礦物) from the soil and air. Their deep network of roots Joins the soil together and stops it from  dying out, making it possible for living things to live in it. Human beings (人類) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks (售貨員) to sell it to us. We need people to prepare our food and
cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government  leaders, mailmen, telephone operators, and many others. We also need other human beings in another way. 
We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone. 
Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else. You know,  being a volunteer is so great!
根據(jù)短文內(nèi)容，判斷下列句子正誤。正確的用“A”表示，不正確的用“B”表示。
小題1:According to the text, different things live on the soil and air.
小題2:The water and minerals join from the soil and air by using sunlight.
小題3:According to the writer, human beings need only farmers.
小題4:When I have done something for someone else, I feel happy.
小題5: According to the passage, everyone needs friends.

小題1:B
小題2:A
小題3:B

Body language is quiet, secret and most powerful language of all. It speaks louder than words.
According to specialists, our bodies send out more messages than we realize. In fact, non-verbal(非語言) communication takes up about fifty percent of what we usually mean. And body language is especially important, when we try to communicate across cultures.
Indeed, what is called body language is so much a part of us that it’s actually often unnoticed. And misunderstandings happen as a result of it. For example, different cultures treat the distance between people differently. Northern Europeans usually do not like having bodily contact（接觸）,even with friends. And certainly not with strangers. People from the Latin American countries, on the other hand, touch each other quite a lot. So it’s possible that in conversation it may look like a Latino is following a Norwegian (挪威人)all over the room. The Latino, trying to express friendship, will keep moving closer. The Norwegian, very probably seeing this as rude behavior, will keep backing away, which the Latino will in return regarded as coldness.
Obviously, a great deal is going on when people talk. And only a part of it is in the words themselves. And when parties are from different cultures, there’s a strong possibility of misunderstanding. But whatever the situation is, the best advice is to obey the golden rule: Treat others as you would like to be treated.
小題1:You may find the passage in _____.
A, a science magazine  B. a guide book 
C. a sports newspaper  D. a story book
小題2:The underlined word this in paragraph 3 refers to ___.
A．the Norwegian keeps moving closer
B．the Latino follows the Norwegian
C．the Norwegian keeps backing away
D．the Latino’s way of expressing friendship
小題3:Misunderstanding of body languages always happens because of the ___.
A．languagesB．friends
C．cultures D．countries
小題4:Which of the following is true?
A．people around the world have the same body languages
B．body language takes up about 50% of our communication
C．body language is the most important in our communication
D．body language is important when trying to communicate across cultures
小題5:If a foreign friend gives a hug to you, you should___.
A．shake hands with himB．give him a hug

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.     Life today has brought new problems. One of the biggest is pollution （污染）. Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.     Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog（煙霧）.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, they mustn’t blow dirty smoke into the air.     We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

Tanzania Tarangire is a national Park which lies in Tanzania．The park itself covers an area of around 2,850 square kilometers, making it the sixth largest park of its kind in the country．I recently visited Tarangire to see what it was like．
One of the first sightings upon entering the park which I found was a huge group of elephants．Our guide told us that Tagrangire was probably the best place in Tanzania to find large group of elephants, and that their population in the park was around 2,500．We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch.
To the right of the elephant group, we noticed a big tree! Our guide informed us that this was a Baobab tree and that they could live for hundreds of years．Compared with this tree, the elephant just looked like dwarfs (much smaller plants or animals)! We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees．
As we continued our drive through the park, we finally reached a watering hole．Our guide warned us that there were lions all around us．It took us all a while to find them, but there they were! Most of them are resting in the shade under bushes, but there was one that was drinking from the watering hole directly in front of us．We then noticed just to our right, there were a couple of fresh zebra bodies — it seemed as if the lions which were resting had killed them! We were unlucky not to have seen the kill, as our guide had mentioned that the zebra bodies were fresh and the kill had happened within the last hour．
Our final big sighting was one that none of us were expecting to see, even our guide! We stopped at a place where there were quite a many cars, with a sleeping leopard（美洲豹）there! We took photos and watched its surprising body before returning to our hotel as it was getting late．
So, I hope you enjoyed my description of Tarangire, and add this amazing park to your very own Tanzania travel route．

It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.
When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.
Scientists have now shown that pet dogs also have “l(fā)eft gaze bias(左視偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.
Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.
“Recent studies show that the right side of our faces can express emotions better than the left. If  true, then it makes sense for dogs and humans to see the right hand side of a face first.”
小題1:Why are dogs seen as man’s best friend according to the passage?
A．Because dogs are the closest animals to humans.
B．Because dogs can read the emotions in humans’ faces easily.
C．Because dogs can understand us better when we feel sad.
D．Because dogs are good at expressing emotions.
小題2:The dogs’ left gaze bias helps them _______.
A．get along well with humansB．express emotions quickly
C．have more understanding friendsD．remember more new faces
小題3:The passage mainly wants to tell us that _______.
A．dogs have been man’s best friends for thousands of years
B．humans have a “l(fā)eft gaze bias”
C．the “l(fā)eft gaze bias” works on all animals
D．dogs can read emotions the same as humans

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by reflected(反射)light(光). We see color because most of the things reflect light. Something is red, because it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
Some of the light is reflected and some is taken in(吸收)and turned into(變成)heat.The darker the colour is, the less light is reflected, the more light is taken in. So dark-colored(深色的)clothes are warmer in the sun than light-colored(淺色的) clothes.

A．see its colorB．see its heat
