【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(xì)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(zhì))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_________．

A. making food taste better

B. making food hotter

C. preventing bacteria getting into food

D. killing bacteria in food

【2】Food goes bad more quickly in hot climates because_______．

C. high temperature helps bacteria grow faster

【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(dòng)的）cars．These cars don’t pollute the air like gas-powered cars．

【題目】Most people want to be happy， but few know how to find happiness. Money and success alone do not bring lasting happiness. Aristotle， a Greek thinker， said，＂Happiness depends on ourselves.＂In other words， we make our own happiness. Here are some opinions to help you be Thappier.

he first opinion of happiness is to enjoy the simple things in life. Too often， we spend so much time thinking about the future ，for example， getting into college or getting a good job —that we can not enjoy the present. You should enjoy life’s simple happiness， such as reading a good book， listening to your favorite music， or spending time with close friends. People who have several close friends often live happier and healthier lives.

Another opinion to living a happy life is to be active and have hobbies. When you are dancing or playing sports， you can forget your problems and time. Many people experience this dancing or playing a sport， such as swimming. You can forget about your problems and only think about the activity.

Finally， many people find happiness in helping others. Studies show that people feel good when they spend their time helping others. If you want to feel happier， do good things for someone. You can help a friend with his or her studies， go shopping to buy food for an elderly person， or simply help out around the house by washing the dishes.

【1】The best title of the passage is ________.

A. Money Makes You Happy

B. The Opinions of Happiness

C. Ideas for Helping Other People to Be Happy

【2】The second paragraph tells us that ________.

A. the more friends you have， the happier you will be

【題目】For a long time being happy was considered something that just happened，and there was nothing special about it．Now we know that getting along with other people is something that we can work at．It is possible to act in such a way that other people will like us better． One way is being unselfish，not wanting everything from our friends．Another way is to look for good points，not bad points in other people．It is surprising how successful this treasure hunt can be．

You do not have to be spineless（優(yōu)柔寡斷的） in order to be popular．In fact，you will be liked or loved if you are not afraid to stand up for your rights（正當(dāng)行為）．But do it politely and pleasantly．Being friendly and polite to your group，to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character．

You cannot expect to be perfect，and you must learn not to be unhappy when you make mistakes．Everyone makes mistakes，and no one is to be blamed if he does not refuse to learn from them．Many young people become discouraged （灰心喪氣的） when they know in themselves qualities that they do not like-selfishness，laziness，and other unpleasant qualities．Just remember that we all have some of these faults（缺點(diǎn)） and have to fight against them．

At the same time，it is important to remember that while you are probably no worse than others，the best way to be happy is to think yourself above other people．When something is wrong，it is good sense to try to make it right．Perhaps you do not like a teacher or a classmate．Try to see why，and look at yourself，too，to be sure that you are not doing anything to make that person dislike you．Some day，things may turn out all right when you have to learn to get along the best with the situation，without thinking too much about it．Worrying never helps in a situation you cannot change．

【1】One of the two ways the writer suggests for us to get along with others is to ____．

A．work hard at everything we do

B．enjoy the best share of everything

C．look for treasure in order to be successful

D．pay more attention to their strong points

【2】If a person wants to be popular，he or she has to____．

A．be polite and friendly

B．give up some rights

C．get away arguing with other people

D．be ready to change his or her character

【3】There is no person but someone should be blamed if he or she

A．is modest and generous

B．does not draw a lesson from his or her own mistake

C．is selfish and lazy

D．is very happy with unpleasant quality

【4】The purpose for the writer to write the passage is to

A．train you to be perfect

B．show you the way to be happy

C．tell you how to act when you dislike a person

D．teach you how to be popular among your friends
