Find Which Direction Is South

Do you have a good sense of direction? If not, please take with you a compass. But if you forget to take a compass, you can still find your way. 

It’s never a good idea to imagine that the family member who was entrusted（委托）with the job of map-reading actually knows where the family is. You can tell by the slightly confused load on their faces that nothing on the ground seems to match the map. Never mind. The shu is shining and it’s still morning. If you don’t know the exact time, you can still find out where south is, but you’ll need to be patient. 

①Find a straight sick and put it in the ground in a place where you can mark its shadow. 

②Try to position the stick as vertically（垂直）as you can. You can check this by making a simple plumb line （鉛錘線）with a piece of string and weight. You haven’t got any string? OK, use a thread from your clothes with a button tied at the end to act as a weight. 

③Mark the end of the shadow cast by the stick. 

④Wait approximately half an hour and mark the end of the shadow again. 

⑤Keep doing this until you have made several marks. 

⑥The mark nearest the stick will represent the shortest shadow, which is cast at midday, when the sun is highest in the sky and pointing to the exact south. 

⑦Pick a point in the distance along the line between the shortest shadow and the stick. 

⑧That point is south of where you are. 

⑨Now you can turn the map, like you did before, and find which way you should be travelling.

6To find the direction, we ought to be patient probably because

A. it is not easy to find a proper stick     

B. it is not easy to position the stick

C. it takes hours to make the marks       

D. it takes about half an hour to make the marks

The passage would probably be most helpful to      . 

A. those who draw maps            B. those who get lost

C. those who make compasses       D. those who do experiments

Which of the following pictures best shows the way of finding the direction of south?

The author presents this passage by      . 

A. telling an interesting story         B. describing an activity in a lively way

C. testing an idea by reasoning        D. introducing a practical method

【小題1】C

【小題2】B

【小題3】A

【小題4】D

Plants have family values, too; it seems, with new research suggesting they can recognize close relatives in order to work together.
An ability to tell family from strangers is well known in animals, allowing them to cooperate and share resources, but plants may possess similar social skills, scientists believe.
Susan Dudley and Amanda File of McMaster University in Ontario, Canada, report they have demonstrated for the first time that plants can recognize their kin.
This suggests that plants, though lacking recognition and memory, are capable of complex social interactions.
“Plants have this kind of hidden but complicated social life，” Dudley said.
The study found plants from the same species of beach­-dwelling wildflower grew aggressively alongside unrelated neighbors but were less competitive when they shared soil with their families.
Sea rocket, a North American species, showed stronger and healthier root growth when planted in pots with strangers than when raised with relatives from the same maternal(母系的) family, the study found.
This is an example of kin selection, a behavior common in animals in which closely related individuals take a group approach to succeeding in their environment, the researchers said.
Kin selection also applies to competition, because if family members compete less with each other, the group will do better overall. “Everywhere you look, plants are growing right up next to other plants，” Dudley said，“ Usually it’s a case of each plant for itself. But sometimes those plants are related, and there are benefits to not wasting resources on being competitive, and there is not really a cost to not being competitive as long as your neighbor is also not being competitive.”
Learning and memory appear to be important for kin recognition in animals, but this isn’t an option for plants, she noted.
Some researchers speculate(猜測) that plants communicate through their roots, identifying themselves using tiny chemical signatures specific to each plant’s family.
【小題1】What’s the main idea of the message?

A．Studies find plants can recognize, communicate with relatives.
B．Kin selection is important for plants.
C．Animals can recognize and memorize their relatives.
D．Competition asks plants to recognize their relatives.
【小題2】Which of the following is NOT right about animals’ social skill?
A．Animals can recognize and memorize their relatives.
B．Animals’ social skill is to cooperate and share resources.
C．Animals’ social skill can recognize close relatives in order to work together.
D．Animals’ social skill is no use at all.
【小題3】Plants’ kin selection is to ________.
A．grow wellB．compete with other kinds of plants
C．strengthen the relationship among siblingsD．find which one is the best
【小題4】From the passage，we learn that ________.
A．sea rocket is a South American species
B．sea rocket grows aggressively alongside unrelated neighbors
C．sea rocket grows aggressively alongside its siblings
D．sea rocket is a kind of bush without flowers
【小題5】How can the plants communicate with each other according to experts’ suppose?
A．Plants communicate by using tiny chemical signatures specific to each plant’s family.
B．Plants communicate with each other through their roots.
C．Plants communicate with each other by their leaves.
D．Plants communicate with each other with their flowers.

第二節(jié)：讀寫任務（共1小題，滿分25分）

閱讀下面的短文，然后按照要求寫一篇150詞左右的英語短文。

Everyone must receive education from teachers at school or at university. Think about all the teachers who have taught you. Can you find which one is your favorite? And the reason? Are the teachers you liked best also the ones who were the most excellent teachers with good qualities? Before you read the following paragraphs, think about what qualities make a teacher extraordinary (優(yōu)秀的).

Most people will say that the several important qualities of a teacher are that he should love his students, that he needs to have an expert knowledge of his subject, and that he should devote himself to his jobs whole – heartedly. All of these can be the good qualities of a teacher but not all.

As we all know, it is impossible for a teacher to love every one of his students that he teaches in his life. Teachers must try their best to make most of their students interested in the subject so that they are able to teach themselves in the future. This requires teachers to master many teaching skills, which include how to control a class and so on. Teachers have to spend much time and energy on their work. However, students also imitate many things of the teacher, so it is also important for teachers to be well – balanced people with interest outside their schoolwork – family, friends, hobbies etc.

[寫作內容]

1）概括短文的內容要點，該部分的字數(shù)大約30詞左右；

2）就“我心目中的好老師”這個主題發(fā)表你的看法，至少包含以下的內容要點，該部分的字數(shù)大約120詞左右；

a．你認為好老師應該具有什么樣的好品質；

I’m fat. I’m too skinny. I’d be happy if I were taller, shorter, had curly hair, straight hair, a smaller nose, bigger muscles, longer legs. Do any of these statements sound familiar? Do you often put yourself down? If so, you’re not alone. As a teen, you’re going through a ton of changes in your body. And as your body changes, so does your image (形象) of yourself. Lots of people have trouble getting used to it and this can affect their confidence.

Some people think they need to change how they look or act to feel good about themselves. But actually all you need to do is change the way you see your body and how you think about yourself.

The first thing to do is recognize that your body is your own, no matter what shape, size, or color it comes in. If you’re very worried about your weight or size, go to your doctor to check that things are OK. But it’s no one’s business but your own what your body is like—finally, you have to be happy with yourself.

Next, find which aspects (方面) of your appearance you can change and which you can’t change and need to accept—like their height, for example, or their shoe size.

If there are things about yourself that you want to change and can do this by making goals for yourself. For example, if you want to get fit, make a pan to exercise every day and eat nutritious foods.

When you hear negative comments coming from within yourself, tell yourself to stop. Try building your confidence by listing three things in your day that really gave you pleasure. It can be anything like the way the sun felt on your face, the sound of your favorite band, or the way someone laughed at your jokes.

1.From the first paragraph, we can infer that           .

A. many teens can’t accept their body change easily

B. most teens like to have a special body image

C. teens prefer to change their body image quickly

D. teens usually change their opinions on their body image

2.Which of the following does the author probably agree with?

A. Change the way other people look at you.

B. Go to your doctor for advice on how to change your body.

C. Realize you can’t change everything about yourself.

D.源Learn from some celebrities on how to change your body.

3.The underlined phrase “put yourself down” in the first paragraph probably means          .

A. make yourself fall down          B. say negative things about yourself

C. force yourself to do something       D. write down your name somewhere

4.The passage is mainly about           .

A. how to adjust to the changes of your body       

B. how to build confidence by changing your body
