Siena is an old city in the north of Italy. It began with a group of people living on its hills over 2,900 years ago. Around the year 1100, Siena became an important business center in Italy. In 1472, the first bank of the world was built in this city and has been doing business ever since.
Today Siena is famous for keeping its “old face”. For example, its city walls, which helped keep the city safe in the past, are hundreds of years old now and look almost the same as before. Also, many old buildings are seen at the Piazza del Campo, the most important meeting place of the city. Few things have really changed in this center of public life for hundreds of years. Now people still go to the open space for sharing news, shopping, or playing sports. There is one more thing that helps keep Siena.s old face: cars cannot enter the city most of the time.
True, Siena is old, but it.s beautifully old. People are welcome to visit this beautiful city and walk into the past.

The cooling material is a very thin board with many layers that could be placed on a roof like solar panels(太阳能电池板).However, instead of turning sunlight into energy as solar panels do, the material turns into infrared radiation(红外辐射).
Shanhui Fan is an electrical engineering professor at Stanford University. He says that the panels have a layer of material that is like sand and they act like a mirror, taking heat out of buildings and reflecting（反射）the light from the sun. He also says both the heat and sunlight are sent 100 kilometers into outer space.
It’s a structure that cools itself without electricity input, ever under the sun. So, what it does is basically radiate heat to outer space and also reflect the sunlight so it doesn’t get heated up by the sun. And the result is that the roof will have a temperature below surrounding air temperature by a large amount.
The panels are cool to the touch, even in the sun. Researchers say they can diminish the indoor temperature.
Mr.Fan says it is like having a window into space. He says the heat is sent directly into space without warming the air.
He says buildings in developing countries that do not have electricity or air conditioning could use the panels.
The Stanford researchers described their technology in the science publication Nature. They say the main problem is creating real cooling systems using the high-tech panels. They say it may be possible to develop a cooling spray (喷雾) that could be used on existing solid structures. The researchers believe the cooling spray technology could be developed in the next three to five years. They say as much as 15 percent of the energy used in the United States is spent providing power to air conditioning systems.

When it comes to the world of finance, first impressions mean everything. First impressions also mean that not everyone is treated equally, and people who look and sound the part are received better than people who make a poor first impression. 36
Timing
It only takes 30 seconds to make a lasting impression, and this is true even when you’re not there. This means don’t be late! 37 Being late shows that you don’t have respect for other people’s time. This is not the impression you want to give your employer, so make sure you are at least 5-10 minutes early.
Handshake
Your handshake can say a lot about you. 38 Too tight, you’re domineering(盛气凌人的). A warm and firm(坚定而有力的) handshake is perfectly acceptable.
Body Language
Your body movements are part of both your personality and appearance. Use them wisely. Carry yourself with confidence, like you’re very successful, even if you’re not. Walking in with purpose and power will give you an air of confidence. _39
Knowledge
If your interviewer asks what you think of the company’s recent efforts, the last thing you want to do is just stare back. Do your research. 40 Who founded it? What is their goal? You want to show the employer that you care enough to read up on who they are.
Doing your research and putting it all together confidently and knowledgeably is exactly what the interviewers look for in an employee.
A. When was the company founded?
B. You may not be able to recover from it.
C. Too loose, you’re weak or not confident.
D. You’re expected to ask intelligent questions
E. Here are a few tips to help you make your first impression.
F. By doing this, you can leave a good impression in your interview.
G. Being late will ruin your first impression in the eyes of your interviewer.

Read the passage and choose the best answer (根据短文内容选择最恰当的答案):
A reader wrote us to say that she was feeling lonely (寂寞) at break because her best friend wasn.t around. Here.s our advice to her — and to all kids who feel lonely sometimes.
It.s hard when a best friend isn.t around — maybe because she moved to a different school or a different class. You may feel lonely at break or lunchtime. You want to have new friends. But how do you make them? Maybe it seems like everybody else already has their friends. But remember, there.s always room for more friends.
Start by looking around your classroom —think about which kids you.d like to play with at break. Look for chances to say hi to them, smile, and be friendly. Offer (给予) to share something or express (表达) your appreciation (欣赏) to them. Invite someone to play with you or say “Do you want to sit here?” in the lunchroom. When you.re at break, walk over to kids you want to play with. Act friendly, and say “Hi, can I play, too?” or just join in.
If you have trouble doing this or if you.re feeling shy, ask your teacher to help you make new friends. Teachers are usually pretty good at matching up friends. The best way to make friends is to be a friend. Be kind, be friendly, share, say nice things, offer to help —and pretty soon, you.ll have one, or two, or even more new friends.
You might still miss that special best friend. But when you see each other, you can share something you didn.t have before she left. You can introduce her to your new friends!

A reader wrote us to say that she was feeling lonely (寂寞) at break because her best friend wasn.t around. Here.s our advice to her — and to all kids who feel lonely sometimes.
It.s hard when a best friend isn.t around — maybe because she moved to a different school or a different class. You may feel lonely at break or lunchtime. You want to have new friends. But how do you make them? Maybe it seems like everybody else already has their friends. But remember, there.s always room for more friends.
Start by looking around your classroom —think about which kids you.d like to play with at break. Look for chances to say hi to them, smile, and be friendly. Offer (给予) to share something or express (表达) your appreciation (欣赏) to them. Invite someone to play with you or say “Do you want to sit here?” in the lunchroom. When you.re at break, walk over to kids you want to play with. Act friendly, and say “Hi, can I play, too?” or just join in.
If you have trouble doing this or if you.re feeling shy, ask your teacher to help you make new friends. Teachers are usually pretty good at matching up friends. The best way to make friends is to be a friend. Be kind, be friendly, share, say nice things, offer to help —and pretty soon, you.ll have one, or two, or even more new friends.
You might still miss that special best friend. But when you see each other, you can share something you didn.t have before she left. You can introduce her to your new friends!

Researchers at Stanford University have developed a new material that can move heat out of buildings and into space. The researchers say the material can cool buildings even on hot days. The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels(板). However, instead of turning sunlight into energy as solar panels do, the material turns heat into radiation. Shanhui Fan is an electrical engineering professor at Stanford University. He says that the panels have a layer of material that is like sand. The panels act like a mirror. They take heat out of buildings and reflect the light from the sun. And he says both the heat and sunlight are sent 100 kilometers into outer space. "It.s a structure(构造) that cools itself without electricity input, even under the sun. So, what it does is basically radiate heat to outer space and also reflect the sunlight so it doesn.t get heated up by the sun. Mr. Fan says it is like having a window into space. The heat is sent directly into space without warming the air.” He says buildings in developing countries that do not have electricity or air conditioning could use the panels. "In areas where electricity is out of reach for many people, there is a potential (潜在的) benefit for storing medicine or even food. In many of these situations, being able to reduce the temperature is important. And this would provide a way to do it.” The researchers say the main problem is creating actual cooling systems using the high-tech panels. They say it may be possible to develop a cooling spray(喷涂) that could be used on present solid structures. They believe the cooling spray technology could be developed in the next three to five years. They say as much as 15 percent of the energy used in the United States is spent providing power to air conditioning systems. 【小题1】The first paragraph mainly tells us ________.
