Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely paid no.

“We don’t know whether the food is safe,” said Zambia’s commerce, Trade and Industry Minister Dipak Patel.

His worries are shared by countries around the world that are in two minds about America’s genetically modified（GM）crops. Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US.

Ever since people started farming, they have tried to crossbreed（雜交） plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other.

But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.

This means they can make crops more productive and resistant to disease by adding genes from other species. They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.

“If left to me, I would certainly not eat GM foods,” said Scottish scientist Arpad Pusztai. “We are putting new things into food which haven’t been eaten before. The effects on the immune system are not easy to predict.”

At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.

Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops.

68. We learn from the passage          .

       A．people have discovered that GM foods will do harm to human health

       B．millions of Zambia people die of eating too much GM foods

       C．people are still not sure if GM foods will do harm to human health

       D．genetic material added to plants will damage our bodies sooner or later

69. What does “in two minds” in the third paragraph mean?

       A．Unsure                B．Worried               C．Likely                 D．Careless

70. the following statements is NOT true about GM foods?

       A．It is produced from plants added genes from other species.

       B．GM foods can have special characteristics.

       C．GM foods will affect people’s immune system.

       D．GM foods have been produced since 1970s.

71. What’s the author’s attitude?

       A．Supportive.          B．Neutral.               C．Doubtful.            D．Critical.

It’s a goal for millions and millions of families every year——keep the Christmas spending within a certain amount, but can still afford the gifts that your loved ones will enjoy. Never has this concern been greater in recent years than right now. Even so, there are several things that you can do to help.

       Hit the sales.

       No one wants to get up at four o’clock in the morning and fight to get the best deal on Black Friday, and it’s surely very tough to pick up the courage and get out there in the cold for a good deal, but sometimes——it can be well worth. Many retailers(零售商) offer specials all through the day——and some even offer online Black Friday specials, so you may still be able to get a great deal on Black Friday.

       Pay close attention to advertisements.

       Once the Christmas shopping season is coming, retailers hungry for business will do just about whatever to get you in the store. Pay very close attention to weekly advertisements of sales among the major retailers and you may be lucky enough to find different prices for the same thing in different shops.

       Shop online.

       Some of us don’t like running from store to store in order to get the best price on the perfect gift, and some of us don’t like to go out in the cold at all——thankfully for us, we can do online shopping.

       The world of online shopping lets people visit all the major retailers as well as some specialty stores that could only be found on the Internet. Customers can find exactly what they are looking for, at the best possible price without ever having to leave the house. With traditional Christmas shopping consumers are sometimes limited to what’s left in stock if they wait too long to get to a particular store.

The first paragraph implies that ______.

       A. nowadays not many people can afford expensive gifts

       B. recently many people don’t want to spend money on gifts

       C. Christmas is a time to make our loved ones enjoy their gifts

       D. Christmas is a time to make us feel free to buy our loved ones gifts

In the writer’s opinion, it is rewarding on Black Friday _____.

       A. if the weather is not very cold                B. if we don’t have to fight for the best deals

       C. if we don’t have to get up early                     D. If we get what we want at a good price

The underlined word “specials” means_______.

       A. some experts in shopping                       B. certain things for especially low price

       C. some kind of help for a certain customer D. things that can only be found on Friday

We can have more choices _____.

       A. on Black Friday                                    B. in a particular store

       C. on the Internet                                      D. from retailers

In this passage the writer means ______.

       A. to tell us the best way to do shopping

B. to attract more readers to do wise shopping

       C. to show us how hard it is to do Christmas shopping

       D. to give us advice on how to get a good deal at Christmas time

第三部分：閱讀理解（共15小題；每小題2分，滿分30分）
請認真閱讀下列短文，從短文后各題所給的A、B、C、D四個選項中，選出最佳選項，并在答題卡上將該項涂黑。
Usually, when your teacher asks a question, there is only one correct answer. But there is one question that has millions of current answers. That question is “What’s your name?” Everyone gives a different answer, but everyone is correct.
Have you ever wondered about people’s names? Where do they come from? What do they mean?
People’s first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.
Some people give their children names that mean good things. Clara means “bright”; Beatrice means “one who gives happiness”; Donald means “world ruler”; Leonard means “as brave as a lion”.
The earliest last names, or surnames, were taken from place names. A family with the name Brook or Brooks probably lived near brook(小溪)；someone who was called Longstreet probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest.
Other early surnames came from people’s occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, smiths were very important workers in every town and village. Some other occupational names are: Carter — a person who owned or drove a cart; Potter  —a person who made pots and pans.
The ancestors of the Baker family probably baked bread for their neighbors in their native village. The Carpenter’s great-great-great-grandfather probably built houses and furniture.
Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some family names were made by adding something to the father’s name. English-speaking people added –s or –son. The Johnsons are descendants of John; the Roberts family’s ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MacDonnells and the McDonnells and the O’Donnells are descendants of the same Donnell.
1. Which of the following aspects do the surnames in the passage NOT cover?
A. Places where people lived.      B. People’s characters.
C. Talents that people possessed.   D. People’s occupations.
2. According to the passage, the ancestors of the Potter family most probably _______.
A. owned or drove a cart          B. made things with metals
C. made kitchen tools or contains   D. built houses and furniture
3. Suppose and English couple whose ancestors lived near a leafy forest wanted their new-born son to become a world leader, the baby might be named _______.
A. Beatrice Smith          B. Leonard Carter
C. George Longstreet       D. Donald Greenwood
4. The underlined word “descendants” in the last paragraph means a person’s _____
A. later generations          B. friends and relatives
