听力原文： Camping can teach you many things, such as how to recognize plants and animals, to set up a tent and to read a map. Most of all, you can anticipate understanding more about yourself and your place in nature.
Whether you decide to travel on foot into the wilderness, to travel by canoe, or simply to drive to a nearby camp ground, you are probably looking for some of the same experiences. Most campers hope to find a simpler life. They tend to forget about work and worries while they enjoy being outdoors.
Because the number of the U.S. campers is increasing daily, the National Park Service advises outdoor lovers to remember several things. First, although it encourages campers to enjoy the outdoors, it urges everyone to treat nature with respect. That involves leaving your campsite cleaner than you found it. It involves learning to enjoy the natural world of plants and animals without disturbing it. Remember that wild animals are wild, and they can hurt you, just as you can hurt them.
The park service invites you to enjoy and explore the world of nature, but at the same time, it expects you to protect each area you visit so that future generations may look forward to having similar enjoyable experiences.
Questions 32 to 35 are based on the passage you have just heard.
32. What is the main purpose for camping？
33. What do most campers look for？
34. What does the National Park Service urge the campers to do？
35. What is the main purpose of the speaker？
(33)
A．To learn to recognize plants and animals.
B．To set up a tent and learn how to cook by yourself.
C．To get to know more about yourself and your place in nature.
D．To learn how to make use of a map to find your way in the open air.
All insectivorous plants have roots, so they don't get all of their nutrients from the insects they take in. Insectivorous plants tend to live in soil that lacks enough nitrogen for them to exist, so they consume their insect victims in order to get the nitrogen they need. There're many types of insectivorous plants in the world--perhaps 500 known species of insectivorous plants worldwide. Of these types of insectivorous plants, we're going to look at one of the better known ones in depth.
The insectivorous plant that we're going to discuss in detail is the Venus flytrap, which is native to North America. It catches insects by suddenly snapping the ends of one of its trap leaves around an insect.
A Venus flytrap has a number of trap leaves and that each trap leaf is divided into two parts. Inside the two parts of the trap leaf are three sensory bristles, which resemble tiny hairs. When an insect touches the bristles inside a trap leaf, the two surfaces of the leaf shut instantaneously, and the insect is trapped inside the parts of the leaf. The Venus flytrap then discharges a digestive liquid into the leaf in order to assimilate the insect and obtain the nitrogen the plant needs in order to survive.
What is the topic of this passage？
A．Insects that feed on plants.
B．Animals that feed on insects.
C．Plants that use insects to survive.
D．Insects that are attractive to plants.

听力原文： We all scream for water when thirsty. (15[A]) But do you know in very hot, dry weather plants also make faint sounds— as if they're crying out for help？
You see, in a plant's stem there're hundreds of "water pipes" that bring water and minerals from the soil all the way up to the leaves. As the ground turns dry, it becomes harder and harder for the plants to do this.
In severe droughts, plants have to fight to pull out any water available. Scientist Robert Winter has found out that when it is really bad their water pipes snap from the tension like rubber bands. When that happens, the whole plant vibrates a little. The snapping pipes make noises 10,000 times quieter than a whisper.
Robert knows that healthy, well-watered plants are quiet. (16[D]) He also knows that many insects prefer attacking dry plants rather than healthy plants. How do the insects know which are healthy plants and which are not？ Robert thinks that the insects may listen for the plants that cry. And then they may buzz in to kill.
To test his theory, Robert is using a device that can imitate plant cries. He attaches it to a quiet, healthy plant so the plant sounds thirsty. Then he watches insects lo see if they attack more often than usual.
If he is right, scientists could use the insects' ability against them. (17[D]) They could build traps that imitate crying plants. So when the insects buzz in to eat, they won't buzz out.
What do plants do when they are thirsty？
A．They give out faint cries.
B．They make noises to drive away insects.
C．They extend their water pipes.
D．They become elastic like rubber bands.

W: Yes, sure.
M: Could you tell me when you became interested in gardening？
W: Well, I was always interested in wild flowers and then in 1980 I read Margery Fish's book Cottage Garden Flowers, which is full of practical advice and personal opinions. But I was reading about plants that I didn't know, so I started to read as much as I could and get different writers' advice. I also used to visit Kew Gardens a lot. That was when we lived in Harrow, West London. I learned a lot from my visit. By the way, Dorset is one of England's three most beautiful towns, the other two being Wiltshire and Somerset. You must know what. I'm often invited to give talks to biology students in college.
M: Yes, certainly. That's why I came here. Now what was your first garden like？
W: It was a very tiny piece of land, which came with my house in Harrow, West London.
M: Do you grow many plants yourself？
W: I don't grow many plants from seeds. But I have several friends and we often give each other plants. My garden is a place which often reminds me of so many people through the plants they've given me.
What was the purpose of Mrs. Whinfield's visits to Kew Gardens？
A．To learn more about plants.
B．To write an article on gardens.
C．To meet the writers whose books she read.
Language is always changing.The earliest known languages had complicated grammar but a small, limited vocabulary.Over the centuries, the grammar changed, and the vocabulary grew.For example, the English and Spanish people who came to America during the sixteenth and seventeenth centuries gave names to all the new plants and animals they found.In this way, hundreds of new words were introduced into English and Spanish vocabularies.Today life is changing very fast, and language is changing fast, too.
There are several major language families in the world.Some scientists say there are nine main families, but other scientists divide them differently.The languages in each family are related, and scientists think that they came from the same parent language.
We learn our own languages by listening and copying.We do this without studying or thinking about it.But learning a foreign language takes a lot of study and practice.
