Some foods can make you sick if they are stored in conditions that are not cold enough to prevent the growth of harmful organisms. Freezing can keep some foods in good condition for months after the growing season. Yet foods can be damaged if they are kept too cold.

The British Development Group says the best time to prepare foods for storage is at harvest time while foods are still in the field.

Use a sharp knife and place the harvested items on a clean surface or directly into storage containers. Do not put them on the ground.

Use clean water to remove dirt， and keep the water clean. Usually it is better not to remove outer leaves from fruits and vegetables before storage. Without leaves， foods can become dry quickly.

Fruits and vegetables must cool from field heat before they are put into storage containers. Cooling them in water can spread funguses （霉菌） throughout the food. A better idea is to harvest foods either early or late in the day， and then leave them to cool naturally.

Some fruits and vegetables must be stored at zero to four degrees Celsius （攝氏度）. Some foods need to be stored at four to eight degrees Celsius， and some need to be stored above eight degrees Celsius for best results.

Wet fruits and vegetables so they do not become too dry. The best time to do this is before storage. Cover the items in plastic once they reach the right temperature for storage. Most fruits and vegetables need the relative humidity （湿度）. Finally， leave spaces between the food containers and the walls of the cold storage area so air can flow. Keep the spaces clean and try not to open the doors too often.

For some minutes， all was quiet in the street. Then， from across the street， someone came walking at a slow pace.

It looked like a man of middle height， dressed in a big raincoat， a soft hat and rubber boots ， and making little sound while walking. No one was in sight. It was a street with two rows of about fifty small houses， and there were three lamps on either side. The lamp nearest the childs house could be seen clearly， but the others were almost hidden by the smoky air. A car passed the end of the street and its lights showed faintly， but clearly enough for the wrinkled skin of a womans small face. The car disappeared as the woman， wrapped up in her coat， reached the doorway of the childs house.

She put a key into the lock quickly， pushed the door open and stepped inside， then close the door without looking round. She began to breathe hard.

She leaned against the door for a moment， then straightened up as if with an effort， and walked towards the door of the front room， the passage leading to the kitchen， and the narrow staircase. She hesitated outside the door， and then went up the stairs. There was enough light from the narrow hall to show the four doors leading off a small landing. She pushed each door open in turn and shone a torch inside， and the light fell upon beds， walls， furniture， a bathroom basin， a mirror which flashed brightness back； but this was not what the woman was looking for. She turned away and went downstairs， then turned towards the kitchen. Clearly there was nothing there， or in the small wash-room， that she wanted. Two rooms remained； the front room and a smaller one next to it. She opened the front room door. After a moment， she saw the childs bed and the child.

Not everyone in the world requires the same amount of living space. The amount of space a person needs around him is a cultural difference， not an economic one. Knowing your own psychological space needs is important because they strongly affect your choices， including， for example， the number of bedrooms in the home. If you were brought up in a two-child family and both you and your sister or brother had your own bedrooms， the chances are if you have two children or more， that you also will offer separate bedrooms for them. In America， for example， they train people to want to have their own rooms by giving them their own rooms when they are babies. This is very unusual in the world. In many other countries， the baby sleeps in the same bed with his parents or in bed near them.

The space in the home also shows a lot about psychological space needs. Some families gather closer to each other and the size of their house has nothing to do with it. Others have separate little corners where family members go to be alone.

Although it is true that psychological space needs are not decided by economic reasons， they sometimes have to be changed a little because of economic pressure. It is almost impossible， however， to completely change your psychological space needs.

9. What does the underlined sentence in Paragraph 1 mean？

A. Nobody needs a required amount of living space.

B. Living space requirements are not always the same.

C. The world requires the same amount of living space.

D. Not two people need exactly the same amount of living space.

10. Why do some families gather closer to each other at home？

A. They have limited living space.

B. They are brought up in a large family.

C. It satisfies their psychological space needs.

D. The children in the family sleep with their parents.

11. What can be the best title for the text？

A. Psychological Space

B. American Way of Living

C. Space Needs in Different Countries

D. Psychological Space and Economic Pressure

Think about the last time you felt afraid. Was it a fear of height？ Did you oversleep on a weekday and fear youd get into trouble at the office？ In any case， you know what it feels like to feel fear.

But one woman doesnt. The woman， code-named “UM”， gave her first-ever interview after years of being studied by a team of researchers. The woman is given a code name because the researchers want to protect her from anyone who would take advantage of her inability to feel afraid.

UM cant tell you what fear is because shes never experienced it. “I wonder what its like to actually be afraid of something，” she said. The formal name for the disease is Urbach-Wiethe disease， which is characterized by a hoarse （粗哑的） voice， small bumps around the eyes， and calcium deposits in the brain.

In the case of UM， the disease has transformed the part of her brain that controls the human response to fear. In the interview， UM talks about an event in her life where she was held at knifepoint and gunpoint， “I was walking to the store， and I saw a man on a park bench. He said， ‘Come here， please. So I went over to him. He grabbed me by the shirt， put a knife to my throat and told me he was going to cut me. I told him， ‘Go ahead and cut me. I wasnt afraid at all. And for some reason， he let me go.”

Doctors who have been studying UMs condition for years have been trying different things that could strike fear into her. They finally figured something out—increasing UMs carbon dioxide levels. Extra carbon dioxide concentration in the blood is known to cause fear and panic in health individuals. Increasing UMs carbon dioxide levels did manage to give her a fright.

12. What is the purpose of asking the questions in Paragraph 1？

A. To start a discussion. B. To tell what fear is.

C. To introduce the topic. D. To talk about an idea.

13. Why is the woman with Urbach-Wiethe disease given a code name？

A. To ensure her safety.

B. To respect her privacy.

C. To meet the researchers demands.

D. To tell her case from other patients.

14. From UMs case， we can know that Urbach-Wiethe disease may ______.

A. lead to an increase in carbon dioxide

B. lead to a decrease in calcium deposits

C. stop the brain from responding quickly

D. stop the brain from functioning normally

15. What will probably happen to UM？

A. Getting the sense of panic.

B. Experiencing another danger.

C. Speaking with a hoarse voice.

D. Dying of the Urbach-Wiethe disease.

Martin Sanders work shows that they were probably fully 2

（grow） and belong to the smallest giant dinosaur species ever found.

Growth marks on dinosaur bones are similar 3 growth rings on trees. The rings are far apart while the animal is young and growing quickly. They get closer as growth slows. “It is

4 （exact） these tight ring marks that we found in the fossil bones，” says Sander. So the fossils must have been from adult 5 （animal）.

Why was this German dinosaur so much 6 （small） than other giant dinosaurs， which grew up to 45 metres long and 7 （weigh） as much as a thousand humans？

150 million years ago， most of Germany was underwater. Scientists think that as water levels rose， there was less and less land and food available. The dinosaur 8 （force） to adapt and evolved into a smaller animal needing less space and food.

Since 1998， scientists 9 （dig） up more than 1，000 dinosaur fossils in the mine. It is one of the few places in the world 10 the bones and footprints of dinosaurs have been found together.

In the second class in this morning， our physics teacher analyzed the hard problem for us and then gave us the key to it. While the key seemed a little unreasonably， no one but I doubted it. Think his key was controversial， I devoted me to the problem heart and soul， trying to figure it out in a different way. Twenty minutes late， I succeeded in finding， in my opinions， the right key. While I explained him my thought， he praised me and said I was right.Through this matter I had learnt that questioning is very important on the road to the truth.
