某实验室通过手术获得下丘脑部分损毁却能存活的大鼠，进行了相关研究。实验：按下表准备两组实验大鼠并作如下处理：向大鼠皮下注入等量的SRBC（山羊红细胞)；7天后，取脾脏组织制成细胞悬液；将适量脾细胞悬液与SRBC混合培养一段时间，然后检测SRBC破裂情况（注：特异性抗体与红细胞表面的抗原结合后，红细胞会破裂，释放血红蛋白。培养液中血红蛋白的含量越高，OD值越大)。

（1)向大鼠皮下注入SRBC的目的是_______。（2)脾细胞悬液会引起SRBC破裂，说明悬液中含有___\_物质，产生该物质的细胞称为_______。（3)有人认为该实验还应增设一组：做手术却不损毁下丘脑，你认为有必要吗？__\__，请说明理由_____。（4)请为此实验拟定一个题目_________。

Mike Maietta was eating lunch when he got a text message from his mom. “Notre Dame,” it said. “Big envelope!” Mike, a senior at a Californian high school, shouted with joy. The big envelope meant that the excellent university in Indiana had offered him a place in its Class of 2013. But the $51,300 annual fee is a big obstacle. So Mike and his parents are considering offers from several other colleges and are calculating the costs of tuition, housing and holiday trips home. This year, money is the driving factor for a growing number of high school seniors, who have to decide what colleges to attend this fall. Less jobs and plunging house prices have changed family spending. “We’re excited that Mike got into eight great schools,” said Mike’s father, an engineer at Microsoft. “But if you consider going to school out of state, you’ve got to think about all of the other costs: moving, flying back and forth for the holidays. You’re looking at about $3,000 a year, just for travel.” As families weigh their choices, some are going back to financial aid offices hoping help packages can be increased. Rachel Brown was happy to get a thick envelope from New York University （NYU). Although she has always wanted to live in Manhattan, she is seriously considering the University of California San Diego （UCSD), because of the high cost in New York. “The tuition for NYU is twice as much as UCSD,” said Rachel, 17. “My mom doesn’t want me to have a big debt when I graduate, and I don’t want that either. I’d have to take out a loan of $15,000. I’ll check and see if there’s any way that NYU can offer me any financial aid.” More than 7.6 million American students have filled out the Free Application for Students Aid, a 19.9 percent increase over last year. This month the Federal Department of Education urged college financial aid officers to give more help to certain families. A record 30,428 students applied for 2,300 places at Stanford, partly because the university increased financial aid for families earning below $10,000.

A lot of us lose life’s tough battles by starting a frontal（正面的) attack — when a touch of humor might well enable us to win. Consider the case of a young friend of mine, who
36 a traffic jam on his way to work shortly  37 receiving an ultimatum（最后通牒) about being late for work. Although there was a good reason for Sam’s being late — serious illness at home — he decided that this by-now-familiar excuse wouldn’t  38 any longer. His supervisor（主管) was probably already pacing up and down preparing a dismissal
39  .
Yes, the boss was. When Sam entered the office at 9:35, it was as  40 as a locker room（更衣室)— everyone was hard at work. Sam’s supervisor  41 him. Suddenly, Sam forced a grin （露齿笑) and  42 out his hand. “How do you do!” he said. “I’m Sam Maynard. I’m   43 a job, which, I understand, became available just 35 minutes ago. Does the early bird get the worm？”
The room burst into  44  . The supervisor clamped off（忍住) a smile and walked back to his office. Sam Maynard had  45 his job — with the only tool that could win, a laugh.
Humor is a most effective, yet  46  ignored, means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying “no”, criticizing, getting the other fellow to do what you want  47 his losing face. For some jobs, it’s the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialogue may start a quarrel.
