Exercise 10. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.
Let's see if you can correctly answer the following question: At what age are Latter-day Saint youth allowed to date? Of course, you probably immediately said, "16". OK, then, how about this one: At what age are you allowed to have a boyfriend or girlfriend? You may be thinking, “Um, 16. Didn't I just answer that?" Well, if that was your answer, then, even though you aced the first question, you missed the second one. Just because you can date when you turn 16 doesn't mean you should immediately start looking for a steady boyfriend or girlfriend. 
For decades, prophets have preached that youth who are in no position to marry should not pair off exclusively. For instance, President Hinckley (1910-2008) said, "When you are young, do not get involved in steady dating. When you reach an age where you think of marriage, then is the time to become so involved. But you boys who are in high school don't need this, and neither do the girls”. So what does this counsel really mean, and what are the reasons for it?
To begin with, there are two different types of dating: casual dating and steady (or serious) dating. The distinction between the two has to do with exclusivity. With casual dating, there is no exclusivity. The two people aren't “a couple” or “an item”, and they don't refer to each other as a “boyfriend” or “girlfriend”. They don't pair off. People who are casually dating are simply friends. This is the kind of dating the Church encourages you to do after you turn 16. You should put aside a need to find a “one and only”. If you're dating casually, you don't expect a relationship to become a romance. You have fun; you do a variety of things with a variety of people. On the other hand, steady dating means the couple is exclusive with one another. They expect each other not to date anyone else or to be emotionally or physically close with other people. Couples who date seriously consider the future, because there is a real possibility they could stay together. This is the kind of dating the Church encourages young adults (generally, people in their 20s) to progress toward, because that's the age when they should be thinking of marrying. 
You should avoid becoming exclusive as teenagers, because an exclusive relationship requires a high level of commitment from both partners, and you're not in a position to make that kind of commitment as teens – neither emotionally, physically, nor in terms of your future plans. As President Boyd K. Packer, President of the Quorum of the Twelve Apostles, has said to youth, “Avoid steady dating. Steady dating is courtship, and surely the beginning of courtship ought to be delayed until you have emerged from your teens”.
118. It can be inferred from the first paragraph that ____.
A. dating doesn't mean having exclusive boyfriend or girlfriend 
B. teenagers are supposed to have a steady boyfriend or girlfriend
C. teenagers date as many boyfriends or girlfriends as they can
D. young people shouldn't be allowed to date at 16 
119. The word “aced” in paragraph 1 is closest in meaning to ____.
A. gave up 	B. misled	C. succeeded in 	D. understood 
120. According to the passage, what is NOT true about casual dating?
A. You can be friend with each other. 	B. You don't pair off exclusively. 
C. You find your "one and only”.	D. You meet different kinds of people.
121. It is stated in the passage that steady dating ____.
A. includes a variety of things with a variety of people 
B. is courtship that you ought to have in your teens
C. requires hardly any commitment
D. suits people who are in their 20s 
122. Which of the following would serve as the best title for the passage? 
A. At what age are young people allowed to date?
B. Casual dating or steady dating. 
C. Make your teenage dating by keeping it casual.
D. Popular kinds of dating for teenagers. 
Exercise 11. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions. 
It has long been seen as a less romantic way of meeting Mr Right. But finding love over the Internet is a good way of meeting a marriage partner, research has showed. It found that one in five of those who have used dating sites to find their perfect partner have gone on to marry someone they met over the web. The study, by consumer group Which?, also revealed that more than half of the 1,504 people questioned had been on a date with someone they met in cyberspace. Sixty-two per cent agreed that it was easier to meet someone on a dating site than in other ways, such as in a pub or club, or through friends. At the same time, the under-35s were more likely to know someone who had been on a date or had a long-term relationship with someone they met through online dating. The survey also found that Match.com and Dating Direct were the most popular dating websites. 
Jess Ross, editor of which.co.uk, said: “Online dating is revolutionising the way people meet each other. Switching the computer on could be the first step to success.” According to industry surveys, more than 22 million people visited dating websites in 2007, and more than two million Britons are signed up to singles sites. Previous research has shown that couples who get to know each other via emails are more likely to see each other again after their first date. Two years ago, a study by Bath University revealed that those who met on dating websites were 94 per cent more likely to see each other after their first meeting than other couples. The researchers studied relationships formed on online dating website Match.com over a six-month period. They found that consummate love - described as a balance of passion, intimacy and commitment - was evident at around 12 months into a relationship. Of the 147 couples who took part in the study, 61 per cent said their relationships had high levels of these components. The researchers also found that men were more likely to find true love on the Internet than women. Some 67 per cent of men but just 57 per cent of women said they had experienced consummate love with an online partner.
Companionate love - a relationship with high levels of intimacy and commitment, but lower levels of passion - was the next most frequently experienced form of love, exhibited by 16 per cent of the study group. Dr Jeff Gavin, who led the team, said: “To date, there has been no systematic study of love in the context-of relationships formed via online dating sites. But with the popularity of online dating, it is imperative we understand the factors that influence satisfaction in relationships formed in this way.” Charlotte Harper, of Match.com, said: “We were thrilled to find so many of our former members have found love. It supports our belief that the Internet does in fact encourage old-fashioned courtship.”
