Passage Three
When jack Davis, 9, looks up at the night sky, he doesn’t see just the stars. He sees his future. The fourth grader from New Jersey has a deep interest in outer space and the alien(外星的) beings he thinks might live there.
In July, Jack heard that NASA was looking for a new planetary protection officer and decided he was the right person for the job. The position, which focuses on preventing astronauts from accidentally bringing extremely small, potentially dangerous alien life-forms back to Earth and ensuring that astronauts do not take Earth-based germs with them into space, pays from $124,406 to $187,000 per year.
Jack wrote a letter to NASA, noting his qualifications for the job. “My sister says I am an alien,” Jack wrote, pointing out that since he is young, he can “learn to think like an alien.” He signed the letter “Jack Davis, Guardian of the Galaxy.”
Within days, Jack received a personal letter from NASA’s planetary science director, James L. Green. “We are always looking for bright future scientists and engineers to help us,” Green wrote.”I hope you will study hard and do well in school. We hope to see you here at NASA one of these days!”
Jack said he was “shocked” when Green’s response arrived. “I shouted, I got a letter from NASA!”
Green says he loves to answer letters from children. He calls his response a “gravity assist.” Spacecraft use gravity assistance from objects like planets and moons to help power the craft toward another celestial(天上的) body. Green hopes a reply can influence a person’s path in life in a similar way.

Passage Four
Online dating has just been revealed to be one of the most common ways to start a relationship. But new research reveals that the concept is still highly flawed(有缺陷的).
An analysis of 400 studies into online dating shows that while it offers access to plenty of other singles, users can be overwhelmed and put off by the volume of choice, defeating the purpose.
The research, by Northwestern University and published in the journal Psychological Science in the public interest, found that the processes involved don’t lend themselves to forming strong relationships. The findings also indicated that the concept of an online profile(介绍) is not entirely useful and “can result in treating potential partners as mere objects”.
Lead author Eli J Finkel explained: “Online dating is a terrific addition for singles to meet. However, there are two problems.” First, studying over seemingly endless lists of profiles of people one does not know, as on Match.com, does not reveal much about them. Second, it “overloads people and they end up shutting down,” he said.
He compared it to shopping at “supermarkets of love” and said psychological research shows people presented with too many choices tend to make lazy and often poor decisions.
The study’s authors also questioned the algorithms(算法) employed by sites such as eHarmony.com to match people based on their interests or personality—comparing it to having a real estate agent of love. While the algorithm may reduce the number of potential partners from thousands to a few, they may be as unsuitable for each other as two people meeting at random, Dr Finkel explained, adding the chances are no better than finding a relationship by walking into any bar. “There’s no better way to figure out whether you’re a match with somebody than talking to them over a coffee or beer,” Dr Finkel said.

32. According to Paragraph 2, online dating _____
A. Attracts a limited number of singles
B. Has been widely studied recently
C. Is criticized as lacking a purpose
D. Offers too many choice
【答案】D
【解析】根据文章“An analysis of 400 studies into online dating shows that while it offers access to plenty of other singles, users can be overwhelmed and put off by the volume of choice, defeating the purpose.”可以得出答案。
33. The phrase “lend themselves to”(Para.3) probably means _____
A. Be opposed to

【答案】B
【解析】根据文章“Psychological Science in the public interest, found that the processes involved don’t lend themselves to forming strong relationships.”可以得出答案。

C. He is an expert in analyzing people’s shopping patterns
