I do not need a calendar to tell me when it is winter. All I need is my nose. When I wake up in the morning and smell the tasty treats my mom is cooking downstairs, I know winter has arrived.
The first one is the smell of chocolate. During the holiday season (from Thanksgiving to New Year’s Day) my mother makes her special hot chocolate. She always adds a peppermint candy cane (薄荷味拐棍糖) to the drink and tops it with cream.
The hot chocolate gets me out of bed, but it is my mother’s chocolate fudge (软糕) that makes me run downstairs. It is a thick chunk (块) of chocolate that tastes like heaven. My mother adds nuts. That gives it more texture (质感).
But my mother isn’t done yet. She also makes a treat she calls “window panes (窗玻璃)”. She takes a few different colored marshmallows (棉花糖) and melts them together with chocolate. The final product looks like a colorful church window, so we call it “window panes”.
These tasty holiday treats are usually eaten after a meal as a dessert. But don’t tell Santa Claus because I secretly eat them all day long.
【小题1】What wakes “me” up in the morning?

Everybody hates rats. But in the earthquake places of the world – Japan, Los Angeles, Turkey – rats will soon be man’s new best friends.

What happens after an earthquake? We send in rescue(救援) dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.

    How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.

    Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “ ‘Robot’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity.

    The “ rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “ It would be fantastic. A rat would get into spaces we couldn’t get to and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building ( but only after an earthquake, of course.)

1.In the earthquake places, rats will become man’s best friends because they can __________.

A. take the place of man in rescue jobs

B. find the positions of people alive who are trapped in buildings

C. serve as food for people alive who are trapped in buildings

D. send signals for the coming earthquake

2.The underlined word “that” in Paragraph 4 refers to(所指)  _________  

A. treating wounded people.               

B. helping rescuers.

C. smelling people among different smells.    

D. carry the wounded people to safety.

3.From the third paragraph we know the rescuers can judge a person is alive by ___________.

A. the nose made by the rat                   

B. the rat’s unusual behavior

C. the signal sent by the radio on the rat’s back   

D. the smell given off by the person

4.In doing rescue jobs, __________________________.

A. rats have better sense of smell than dogs. 

B. dogs don’t need to be trained to smell people.

C. robots’ sense of smell can be affected by other smells around.

D. rats can see in the dark and are smaller than robots.

5.After reading the passage we can know ______________________________.

A. rats have taken the place of dogs in search for people.

B. the “ rat project” has been completed

C. people are now happy to see a rat in a building

D. now people still use dogs and robots in performing rescue

Answer the questions（根据短文内容回答下列问题)

Your Nose is Busy and Important

Your nose has many important jobs, and is always busy.

Smelling

Smelling helps you gather information about the world around you. A good scent (气体),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.

Breathing

Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (细菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.

Tasting

Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (贡献) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn’t taste as good because without smell, food loses most of its flavor.

Smell memory

Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(气味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.
