【題目】Since the first Earth Day started on April 22, 1970, people around the world have been encouraged to protect the environment and natural resources．Gaylord Nelson started this holiday．On the first Earth Day，20 million people took part in Earth Day events．

Earth Day activities can include learning something about technology like cars that are more environmentally friendly and special houses that save energy and water．An organization called the Earth Day Network encourages people to use clean energy which doesn’t pollute the environment．Most of our energy comes from fossil fuels （化石燃料） that are found underground．Coal， oil and natural gas are examples of fossil fuels．Fossil fuels come from plants and animals that lived millions of years ago．Burning fossil fuels to create energy pollutes the air and water．Many scientists think that burning fossil fuels also increases the temperature of the earth．To reduce the use of fossil fuels．scientists are experimenting with hydrogen-powered （氫化發(fā)動的）cars．These cars don’t pollute the air like gas-powered cars．

Some scientists guess that by 2025, fossil fuels will run out．When people can no longer use gasoline， they may use fuel cells instead．Fuel cells use hydrogen to create energy．People do not need to worry about hydrogen running out， because it is renewable and replaceable．

In Washington，D．C．， a few people drive cars that run on fuel cells．When these cars need more energy, drivers can go to a hydrogen pump．The first hydrogen pump for the public opened in November 2004， marking an important step toward a cleaner environment．

試題分析：短文大意：這篇短文主要介紹了自第一個地球日以來世界各地的人們已經被鼓勵保護環(huán)境和自然資源。在第一個地球日，2000萬人參與活動。為了減少污染，在華盛頓有人開始開燃料電池的汽車。

【1】B細節(jié)理解題。根據短文第二段scientists are experimenting with hydrogen-powered (氫化發(fā)動的) cars． These cars don’t pollute the air like gas-powered cars描述，氫化發(fā)動的汽車不像油發(fā)動的汽車一樣污染空氣，故選B。

【2】C推理判斷題。根據第三段科學家的推測可知，到2025年化石燃料將耗盡，人們將利用氫制造能量的燃料電池，故大約還能使用化石燃料十年。故選C。

【3】A細節(jié)理解題。根據短文描述，可知A項沒有在文章中提及。

【4】C細節(jié)理解題。根據第二段Burning fossil fuels to create energy pollutes the air and water描述燃燒化石燃料創(chuàng)造能量時會污染空氣和水。故選C

【5】A細節(jié)理解題。根據第三段People do not need to worry about hydrogen running out， because it is renewable and replaceable描述人們不必擔心氫耗盡，因為它是可再生的和可替換的。

Do you go to school by bus? It is very important for you to know how to be safe when taking a bus, no matter whether you like it or not.

【題目】We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. This article gives some suggestions on how to give a successful speech.

So, you have to give a speech and you’re frightened. You get nervous, you forget what you want to say, you stumble(結巴)over words, you talk too long and your listeners feel tired of your speech. Later you think, “Thank goodness, it’s over. I’m just no good at public speaking. I hope I never have to do that again.”

Cheer up! It doesn’t have to be that bad. You can do the following things to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion(場合)? Why are you speaking? Then, collect as many facts as you can on your subject. Spend plenty of time doing your research. Then spend plenty of time putting your material in good order so that your speech is clear and easy to follow. Use as many examples as possible and use pictures, charts and graphs if they help you make your points clearer. Never forget your listeners. Don’t talk over their heads and don’t talk down to them. Respect your listeners. They will enjoy your thoughtfulness.

Just remember: Be prepared. Know your subject, your listeners and the occasion. Be brief. Say what you have to say and then stop. And be yourself. Let your personality come through so that you make person-to-person contact with your listeners.

If you follow the simple things, you’ll see that you don’t have to be afraid of public speaking. In fact, you may find the experience so enjoyable that you volunteer to make more speeches! You’re not confident yet. Give it a try and see what happens.

【題目】Why do you think people who live in some hot countries eat very spicy(辛辣的)food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food，or is there some connection between spices and healthy food? Researchers from Cornell University think that it is because spice plants have some important chemicals. These chemicals can kill bacteria(細菌)which spoil food．

“Most common spices can kill 75 to 100 percent of the bacteria in food，”explains one of the scientists．The bacteria grow more easily and spoil(變質)food more quickly at higher temperatures．For this reason，it is more difficult to keep food from spoiling in hot climates,

Do you like your food spicy? Your answer probably tells something about the country you come from．If you like spicy food，it is possible that hundreds of years ago，when there were no fridges，people in your country started using spices to keep the food from spoiling．The traditional spicy dishes helped those people to live longer，healthier lives．Today，in a time of fridges，the spices just make the food taste good．

【1】The chemicals in spices keep food from spoiling by_________．
