If I ask you to shut your eyes and gave you a piece of apple to eat, would you be able to tell me what it is just by tasting it? Of course, you could. Your tongue is covered with tiny “taste buds” which help you know what different foods taste like. Do you know that foods would taste different if you did not have a nose? This experiment shows how important your nose is when you taste things.
What You Need:
• a friend to help
• small pieces of any food like carrot, orange, banana
• small pieces of apple, raw(生的) potato, and onion
What You Do:
There are actually three different experiments. You and your friend should take turns to try them on each other.
Experiment 1:
Have your friend close her eyes and open her mouth.
Give her a piece of the food and ask her to taste it.
Then, ask her what she thinks it is. She will probably guess correctly.
Experiment 2:
While your friend has her eyes closed, give her a piece of the raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato (but don’t call it by name) and tell you what she thinks it is. She will say it is a piece of apple!
Experiment 3: (for the brave)
Take a piece of raw onion. You don’t have to close your eyes this time. Squeeze your nose closed with your other hand so that no smells can get into your nose. Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion.
The Science Secret
You already know the science secret. Your nose and your tongue work together to make food taste the way it does. Your tongue, however, can taste only certain flavors like salty, bitter, sour, and sweet. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them. Oh, and you might use this science secret the next time you are told to eat something you don’t like the taste of. If you hold your nose while you eat it, you won’t “taste” it at all. According to this article, what could a reader know about food?
| A．People hold their noses to eat onions. | B．If you can smell potatoes, you will taste apples. |
| C．People need a sense of smell to taste some food. | D．If you close your eyes, food will taste better. |
What is the most likely reason Experiment 3 is called “for the brave”?
| A．You keep your eyes open. | B．You have to eat a raw onion. |
| C．You have to squeeze your nose. | D．You do the experiment alone. |
What’s the best title of the passage?
| A．Your Eyes Knows | B．Your Nose Knows |
| C．Your Mouth Knows | D．Your Tongue Knows |
I was just out of college, only three days into a graduate (研究生)year in England,and I was pulling a heavy bag and suitcase(箱子)through the London Underground. I was also crying out of control.
The day before yesterday, my uncle told me never to speak to him, his wife, or my two cousins again.Earlier, I made a joke. I didn't mean to hurt my aunt's feelings, but it did.I spent the evening in an ugly blue telephone booth (电话亭). crying as I spoke to a family friend who lived in England.
When I left the phone booth, I went back to a silent house with three closed bedroom doors. In the morning, I heard everyone get up and leave for work and school. I wrote a note to say sorry and pulled my bags to the train station. When I got into London, I had to take the underground to Angel Station to get to my family friend's house.
I was familiar with the underground, but at the time, it was just endless white tiles（瓷砖).Coming to England seemed like a bad decision. Crying yet again, I tried to lift my suitcase up the stairs.
When I was trying hard to walk forward, there were hands. Each time I faced another group of steps,a hand would lift the suitcase. At the top of the steps, the hand would let go, and I'd pull the suitcase to the next group. And just as I wanted to try again，another hand would appear.
It happened several times. I never looked up, because I couldn't stop crying.Each hand looked different, and many different people helped me, without asking or saying anything. I couldn't look up. I wasn't able to say thank you.
I went on to have an amazing year studying in England, but that was the last time I saw or spoke to any of my uncle's family. Yet when I think about that terrible loss in 2008, I remember those strangers' hands. They were there when I needed them, and even now, they help me out of the sadness of that memory. I think of them as I ride the underground in Washington D. C. today, and I watch the citizens and tourists to offer hands at any time.What was the writer's feeling while she was walking in the station?
| A．She felt sad and helpless at first, but might feel warm later. |
| B．She was looking forward to getting help from friends. |
| C．She expected to leave London and go back home |

| B．I left my uncle's family and haven't contacted them since then |
| C．I didn't say thank you to those who gave hands to me |
| D．I lost my good mood and felt sad when I left my uncle's family |
What is the passage mainly about?
| A．It tells us a story about an unlucky and homeless college student. |
| B．It.describes the writer's experience through the underground. |
| C．It expresses the idea of giving hands to strangers who are in need. |
| D．It shows the helping hands that writer got from strangers. |
Sometimes, you feel down or unhappy and it is hard to come back to your high spirit. So if you're having a bad day and need a boost，then help is just a click away.
A website is trying to offer people positive(积极的)messages from strangers to cheer them up. It announces to be“the nicest place on the Internet"，where happy people can present their positive thoughts and feelings to those who are in low spirits.
The website, thenicestplaceontheinter.net, lets people post videos of themselves blowing kisses and leaving positive and encouraging messages to lift visitors' spirits.
The website was created by Jeff Lam and is considered to help many people out when they feel low. The well-known artist who lives in San Francisco said he came up with the idea when he and his friend Lauren were having one of those bad days.
"We tried to become cheerful，but none of the usual methods seemed to be working. Not music. Not food. What we hoped was something positive, honest and good.So with only a camera and work-free weekend, we created‘The Nicest Place On The Internet," he explained on his website.
One user of the site, Joseph Meehan, 27, from Birmingham, said,“it's a fun and
exciting website. I visit every once in a while when I'm missing my friends or family. I think it could really be a help to people that are feeling down or sad. It may even stop them from doing something stupid. You can also post your video to the website, and they add it to the series. It's very easy to share the love.”
Mr. Lam is now working on a new project that allows people to leave positive voicemails for strangers. The idea is that strangers send an audio(声音)diary by leaving a voicemail and then anyone can listen to it.The underlined word "boost" in paragraph 1 probably means
| A．鼓舞 | B．放松 | C．休闲 | D．提高 |

Last fall a beaver moved into the small stream beside our house. He began taking down small trees right away. and in a couple of weeks our stream turned into a pond(水塘).Every day,he added more to his dam(水坝)and to his house. We're sure you've all heard the saying, "as busy as a beaver". Now, we understand this saying as we saw the work that this beaver did over a very short period of time.
We thought that would be the last of the beaver's busy activity as winter came. To our amazement, however, he started chewing(咀嚼)on a very large tree. The tree was over 18 meters tall and around 1.5 meters in diameter(直径).We were amazed at the challenge this beaver was trying. All winter, he chewed and chewed. He had setbacks(挫折)as we faced major winter storms and ice-cold weather. But sure enough, when the weather allowed, he would come back and chew a bit more.
The beaver's first goal(目标)was to survive--to build home for the winter. Working every day with that goal in mind, he successfully achieved that goal. But the large tree he started chewing on last fall was a future goal一he wanted the large tree to provide new food and branches(树枝)for the coming spring. Even with the setbacks he faced over the winter, he never gave up until he reached it.
Our beaver's experience reminds us that we need to set goals for tomorrow. Sometimes just surviving seems to take up all of our time. But, if you do just a little bit when time allows and stick to your future goal, you will achieve it.
When faced with setbacks, have your goal in heart and don't let the setbacks stop you. Keep chewing like the beaver, and you will achieve your goal in the end.
What is the purpose of the beaver's chewing on the large tree?
| A．To provide more food for the winter because of the snow. |
| B．To add more branches to his dam and his house.§X§K] |
| C．To prepare new food and branches for the coming spring. |
| D．To keep working every day with a goal in mind. |
Here is。paragraph(段)"When spring arrived, we went down to see the beaver's progress. The tree was about to fall. Our beaver had almost completely chewed around and through the whole tree.”According to the passage, it should be put______
| A．between paragraph I and paragraph 2 |
| B．between paragraph 2 and paragraph 3 |
| C．between paragraph 3 and paragraph 4 |
| D．between paragraph 4 and paragraph 5 |
The best title of this passage might be_____

Last year, a special kind of glove came out. It was invented to help bind people to learn Braille,which is a special system for the blind to read by touching. Shaking motors (震动马达) are put on each finger of the glove. They can make different sounds to tell a user which letter he is touching.Recently, two British college students have invented another special glove for the blind. It can make the user feel small and quick movements. An ultrasonic sensor(超声波传感器)with a battery is put on the back of the glove. When the user wearing the glove is close to an object（物体）, ultrasonic waves( 超声波)from the glove are sent out (发出). As soon as they hit the object in front, the waves will return to the glove. Then the waves cause the glove to shake. And the ultrasonic sensor makes different kinds of sounds. The sounds make the user know how far he is from the object.
In the college invention competition, the two students got first prize and won 1,540 pounds. One of the designers said, "Now the ultrasonic sensor on the glove is quite large. We're going to use the money to develop a smaller and lighter ultrasonic sensor."

Long ago, there was a queen who lived in a palace. She felt bored and said to her advisor(顾问 ),
"AIl the things around me are too boring. I need a different kind of beauty. Let everyone know that I will hold a competition for the most beautiful thing in the world. And the prize will be this crown (王冠)."
Several days later, lots of people came to the competition and showed their things. The queen was not satisfied with what she saw. The advisor suggested, "What you are looking for cannot be brought to you. You must look for it by yourself. What about a journey?"
The queen was interested in the idea, so she started immediately. As she was on top of the hill near her palace, she looked down and suddenly something cried in her heart. "Why have I never found my palace so beautiful?"
