     Many (许多) English people (人) have three names, a first name, a middle name and a last name
(or a family name). For example (例如), my name is James Allan Green. James is my first name. Allan
is my middle name. Green is my last name. People don't use (用) Mr., Mrs., Ms. or Miss before their
first names. People should (应当) use them before their family names.   
     But in China, people use Mr., Mrs., Ms. or Miss before their first names. Because in China, the first
name is the family name. For example, his name is Lin Tao. "Lin" is his family name, and "Tao" is his
given name (名).
1. My name is James Allan Green. Which (哪一个) is my family name?    
[     ]
A. James.  
B. Allan.  
C. Green.  
D. Allan Green.
2. If (如果) his name is Lin Tao, which is his family name?
[     ]
A. Lin. 
B. Tao.  
C. Lin Tao. 
D. Zhang.
3. We use (使用) "Mr." before (在....之前) _____ in the name "James Allan Green".   
[     ]
A. James 
B. Allan 
C. James Allen 
D. Green
4. In China, we use "Mrs." before _____ in the name "Wang Ping".   
[     ]

(13分)请回答胚胎工程和基因工程方面的问题:
(1)应用胚胎工程技术可以培育出“试管牛”。试管牛的培育需经过体外受精、       、
       以及在母体中发育和产出等过程。
(2)在“试管牛”的培育过程中,要使精子和卵母细胞在体外成功结合,需要对精子进行处理,使其         。另外,培养的卵母细胞需要发育至减数第二次分裂的中期,该时期在显微镜下可观察到次级卵母细胞和          。
(3)通常奶牛每次排出一枚卵母细胞,采用激素处理可使其一次排出多枚卵母细胞,常使用的激素是                。
(4)利用基因工程可以获得转基因牛,从而改良奶牛的某些性状。基因工程的四个基本操作步骤是          、基因表达载体的构建、         和         。若要获得的转基因牛分泌的乳汁中含有人干扰素,则所构建的基因表达载体必须包括:某种牛乳腺分泌蛋白基因及其启动子、         、         、         和复制原点等。将该基因表达载体导入受体细胞所采用的方法是         (显微注射法、农杆菌转化法),为获得能大量产生人干扰素的转基因牛,该基因表达载体应导入的受体细胞是          (受精卵、乳腺细胞)。
