Why do I have trouble telling foods apart when I have a cold?

Try this simple experiment：Hold your nose. Place a piece of raw carrot in your mouth and chew. Then, as you are still chewing, let go of your nose. Do you taste the difference?

The sense of taste and the sense of smell work together as you eat The taste buds (味蕾）on your tongue have 4 nerve receptors(神经感受元）in them. They can respond to only four different tastes—sweet, sour, salty, and bitter. All the other hundreds of tastes come from how foods smell to you.

Foods give off invisible (无形的)fumes (烟，气）that breathe into your nasal, passages (鼻道）. The olfactory (嗅觉的）or smelling nerves (嗅感神经) react to these fumes and you become aware

of (意识到）the specific smell of these foods.

When you have a cold, however, your nasal passages are clogged (阻塞,填满）with mucus (黏液).Your sense of smell is cut off，just as it is when you hold your nose.

When you can?t smell the foods you eat, it becomes hard to tell them apart.

Many students ask for advice about improving their English. There are three basic questions.

The first question is about real English. Li Hao from Hubei wrote, “I enjoy watching English films and listening to real English songs. But it takes a long time. What do you think?” This is a great way to learn English! Talk about the film or song with your friends, and guess the meaning of the new words. Just enjoy yourself!

The second question is about speaking. Sam, from Suzhou wrote, “Our school has a foreign teacher. But I?m shy and can?t speak to her. What should I do?” When I visit China, lots of people in the street say, “Hello! How are you? Where are you from? Do you like China?” These are good questions to start a conversation. Many people are shy when they speak English, so before you begin, take a deep breath and smile! Smiling always helps.

The third question is about vocabulary. Oliver, from Anhui wrote, “I want to remember all the new words. I wrote them down, but I forget them quickly. What should I do?” Try to remember eight or nine words a day. Write them on pieces of paper and place them in your bedroom. Say the words when you see them, and change them every day. And when you?re shopping, how about counting the English words, or saying the English names for everything you see?

Over 30% of the natural world has been seriously destroyed by humans (人类) over the last 30 years. This is because the number of people living on Earth is nearly six billion (十亿). All of these people need food, space and energy. As a result, lots of Earth?s natural resources will be used up. When we destroy our earth to get natural resources such as wood or oil, animals often lose their living space. They cannot have enough food, and they will get hurt or die.

The World Wide Fund for Nature (WWF) is an international charity. It tries to prevent humans from destroying more of nature than is necessary. For example, in China WWF is working with the local government to reconnect (重新连接) some small lakes in Anhui Province to the Yangtze River and to create(创造) more protected areas so that China?s natural beauty will not be lost in the future. WWF works in more than 50 countries, saving rainforests and stopping hunters from killing rare animals and protecting traditional ways of life in areas where they are in danger of being lost. WWF?s main goal is to encourage development that does not harm the environment and the animals that live in it. Even though the charity is known all over the world, and a lot of people support the goals of WWF, not so many donate money often. This makes it difficult for the charity to do all the things it wants to do.

1. Why has over 30% of the natural world been destroyed?

A. Because hunters are killing rare animals.

B. Because not enough people help WWF.

C. Because WWF does not have enough money.

D. Because there are so many people living on Earth.

2. How has WWF helped in China?

A. They have protected traditional ways of life.

B. They have helped to protect China?s natural beauty.

C. They have saved many rainforests in Anhui Province.

D. They have built some bridges over the Yangtze River.

3.What is WWF?s main goal?

A. To save rainforests.

B. To stop hunters killing rare animals.

C. To get more people to donate money.

D. To protect the environment while developing.

4.Why is it difficult for WWF to do all the things they want to?

A. Because too many people do not know WWF.

B. Because WWF doesn?t have enough money from donations

C. Because there are too many problems for them to solve.

D. Because WWF doesn?t encourage development.
