[填空题]

Dear Sirs,
I’m writing to tell you that your latest shipment (装运) of apples is not up to the standard we expected from you. Many of them are bruised (擦伤), and more than half are covered with little spots. They are classed as Grade A, but I think there must have been some mistake, as they are definitely not Grade A apples.
We have always been satisfied with the quality of your produce (农产品), which makes this case all the more puzzling. I would be grateful if you could look into the matter. We would be happy to keep the apples and try to sell them at a reduced price, but in that case we would obviously need a credit (部分退款) from you. Alternatively, you could collect them and replace them with apples of the right quality. Would you please phone me to let me know how you want to handle it
Yours faithfully

[简答题]
Should A Kid Be Guided to Tell a White Lie

It’s my family’s tradition to exchange girls on Christmas Eve. Before we did so, I whispered to my uncle and his wife, "Just want you to know: I think what I got you is really cool, so just tell me you like it, no matter what, okay "
I know that sounds rude, but there’s another Christmas custom in my family: we give each other weird gifts.
There is a sweet reason for this. My grandparents grew up during the Depression, and there were years when they had no gifts at all. So my grandmother and her siblings(兄弟姐妹) would gift-wrap their old socks and clothes, just so they had something to open on Christmas. Pretend presents were better than none at all.
My grandmother never really got over those early years, so, for the rest of her life, she went a little crazy at the holidays. She’d start buying gifts in October. It didn’t matter what it was. Socks, toothbrushes,

[单项选择]

Countless people are born with(生来就具有某种特点)the susceptibility to inherit a genetic disease. But scientific progress, especially the art of interfering with(干涉,阻碍) the genetic makeup of the human body, has helped doctors prevent more and more inherited disorders in the last decade.
Dr. Thomas Caskey of the Baylor University College of medicine in Houston, Texas, is a pioneer in molecular biology(分子生物学). Through the techniques of genetic engineering(基因工程), he transfers genes from one organism to another. Caskey uses a certain type of virus, called a retrovirus(逆转录病毒), as the vehicle for the gene transfer. He first cripples the virus by removing the portion it needs to reproduce itself. The crippled virus becomes harmless while still being able to deliver a cargo to its destination.
The cargo in Caskey’s experiment is the human A-D-A gene, taken from bone marrow. A-D-A stands for(代表) adenosine deaminase(腺苷脱氨酶), an important component of the human immune system. A
A. human blood
B. human bone marrow
C. mouse blood
D. mouse bone marrow

[简答题]阅读《白雪歌送武判官归京》,回答下列小题:
北风卷地白草折,胡天八月即飞雪。忽如一夜春风来,千树万树梨花开。散入珠帘湿罗幕,狐裘不暖锦衾薄。将军角弓不得控,都护铁衣冷难着。瀚海阑干百丈冰,愁云惨淡万里凝。中军置酒饮归客,胡琴琵琶与羌笛。纷纷暮雪下辕门,风掣红旗冻不翻。轮台东门送君去,去时雪满天山路。山回路转不见君,雪上空留马行处。
