I have had all kinds of interesting neighbors since the early days of my life. When I was a baby I would stand in my wooden crib(婴儿床) and watch the world go by through the window. Some neighbors watched me watching the world go by with by big, wondering eyes and found me very interesting. They used to call me “the beauty at the window”.

The early neighbors I could remember were from the second house I lived in. Peter and Paul were twins. We went to play school together although they were a year older than me. I well remember the Alsatian they had which ran into me when I was invited to their fifth birthday party. Needless to say, I was well-known for my loud screams after the party. But they said the pet was scared of my screams and didn’t appear until the party was over.

Peter and Paul were the first boys who encouraged me to climb the gate. I could never tell the difference between boy and girl behaviors—I just did what I thought was fun. Not only did I have a great time performing that first climb, I also got my skirts dirty, and was criticized by my mother.

The Japanese neighbors I had living in this same house were my favorite, as they introduced me to sea-salt baked shrimps (烤虾) which were so crisp that you could eat the shrimp totally. They gave me some seaweed for my birthday. Thankfully, no other member in my family enjoyed the seaweed as I did. Perhaps what my mother used to joke to me was true, that I was picked up out of the dustbin that belonged to a Japanese home.

Maybe sometimes it is difficult to find good neighbors in this society. But all it takes is a spark(火花) to get a fire going. I have decided to be that spark wherever I live and pass love on to my neighbors.

1.We can guess "the Alsatian" in the twin brothers' home is ________.

A. a small child

B. an interesting toy

C. a dog

D. a bicycle

2.From the passage we can know that the author ________.

A. enjoyed the Japanese neighbors' cooking style most

B. had difficulty getting on with the twin brothers' family

C. was described as interesting when playing with boys

D. had many neighbors that worked in restaurants

3.What can we infer from the passage?

A. The author often moved to other places.

B. Peter and Paul liked to play tricks on others.

C. The neighbors the author had were good at cooking.

D. The author had a good relationship with her neighbors.

Ever since they were first put on the market in the early 1990s, gentically mondified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would, is it the best solution?

Despite what it promises, GM technology actually has not increased the production potential　　 of any corp. In fact, studies show that the most widely grown GM crop. GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.

Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.

At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.

As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.

1.The author develops the second paragraph mainly　　　　 .

A.by classification B.by comparison

C.by example D.by process

2.What does the underlined word “boost ” in the third paragraph probably mean?

A.Control. B.Evaluate C.Obtain. D.Increase.

3.GM companies promise farmers that they will benefit from ______________.

A.practicing “green” farming B.use of less chemicals

C.fair distribution of their crops D.using more crops for fuel

4.Which of the following best describes the attitude of the author towards GM technology?

A.Optimistic B.Defensive C.Disapproving D.Casual
