I’d been living with my wife for eight years and one night. Morn says, "I guess you guys are never going to get married. I mean, you’ve been through jail together, you’re living together, but…, oh, forget it." "Oh, well," I said," put it like that and I’ll marry your daughter tomorrow." Actually, I don’t know what we were waiting for, except that for a guy it’s never the right time to get married. I’ m also suspicious of any two people who don’t struggle with that decision. Part of my problem was that I was still lusting in my heart after other ladies. But somehow I knew that I wasn’t going to find another woman remotely as great as my soon-to-be wife. It’s a good thing my mother-in-law finally spoke up. I finally gathered my courage one day when we were having a picnic, and popped the question. I also gave my wife a big tourist pamphlet about Switzerland. I wasn’t taking any chances. She said no. It killed me. I felt sick to my stomach. I lost my appetite. Our dog just stared at me, thinking, "If you’re not going to eat your lunch, I will." Finally, I said, "But the Switzerland trip is yours if you say yes." "Switzerland , "she said, "is filled with precise, humorless people." "Maybe I should have suggested Paris" For a minute it seemed as if my change in travel plans would rate a solid "maybe". But she said no again. When we woke up the next morning, she told me that she’d slept on my proposal. "I guess I was a little rude to you last night," she explained. Meanwhile, I’m figuring I’m off the hook for this marriage thing for at least another eight years. I could afford to be generous. "I asked, you said no. It’s okay," I said. I might have looked a little too relieved because later that day she gave me a little box. Inside was a gold watch. On the back was inscribed. "Yes. I’ve reconsidered." I liked the watch, so I did the right thing. The best title for this text would be ______.
Many students find the experience of attending university lectures to be a confusing and frustrating experience. The lecturer speaks for one or two hours, perhaps (61) the talk with slides, writing up important information on the blackboard, (62) reading material and giving out (63) The new student sees the other students continuously writing on notebooks and (64) what to write. Very often the student leaves the lecture (65) notes which do not catch the main points and (66) become hard even for the students to understand. Most institutions provide courses which (67) new students to develop the skills they need to be (68) listeners and note-takers. (69) these are unavailable, there are many useful study-skills guides which (70) learners to practice these skills independently. In all cases it is important to (71) the problem before actually starting your studies. It is important to (72) that most students have difficulty in acquiring the language skills (73) in college study. One way of (74) these difficulties is to attend the language and study-skills classes which most institutions provide throughout the (75) year. Another basic strategy is to find a study partner with whom it is possible to identify difficulties, exchange ideas and provide support.

Our brains could be hard-wired to be male or female long before we begin to grow testes(丸)or ovaries(卵巢)in the womb. This discovery might explain why some people feel trapped in a body that’s the wrong sex, and could also lead to tests that reveal the true "brain sex" of babies born with ambiguous genitalia(生殖器). Till now, the orthodoxy among developmental biologists has been that embryos develop ovaries and become female unless a gene called SRY on the Y chromosome is switched on. If this gene is active, it makes testes develop instead. This switch is seen as the key event in determining whether a baby is a girl or a boy. Only after the gonads(性腺) form and flood the body with the appropriate hormones, the theory goes, is the sex of our minds and bodies determined. But in a study of mice, a team at the University of California, Los Angeles, has now found that males and females show differences in the expression of no fewer than 50 genes well before SRY switches on. "It’s the first discovery of genes differentially expressed in the brain, "says Eric Vilain, who led the UCLA team. "They may have an impact on the hard-wired development of the brain in terms of sexual differentiation independent of gonadal induction." Vilain is presenting details of seven of the 50 genes to the annual meeting of the American Society of Human Genetics in Baltimore this week. Three of these genes are dominant in females and four are dominant in males. The next step for Vilain and his team will be to show that the genes in question really do influence brain sexuality—and not just in mice. This is likely to be a much tougher proposition than merely showing there are differences in expression. But if the findings are confirmed, they could one day yield blood tests that allow doctors to establish the brain sex of babies born with genitalia that share features of both sexes. At present doctors and parents have to guess which gender to assign for surgical "correction". The first paragraph tells us that ______.
