Passage Two
Questions 26 to 30 are based on the following passage.
Engineering students are supposed to be examples of practicality and rationality, but
when it comes to my college education I am an idealist and a fool. In high school I
wanted to be an electrical engineer and, of course, any sensible student with my aims
would have chosen a college with a large engineering department, famous reputation and
lots of good labs and research equipment. But that’s not what I did.
I chose to study engineering at a small liberal-arts (文科) university that doesn’t
even offer a major in electrical engineering. Obviously, this was not a practical choice; I
came here for more noble reasons. I wanted a broad education that would provide me
with flexibility and a value system to guide me in my career. I wanted to open my eyes
and expand my vision by interacting with people who weren’t studying science or
engineering. My parents, teachers and other adults praised me for such a sensible choice.
They told me I was wise and mature beyond my 18 years, and I believed them.
I headed off to college sure I was going to have an advantage over those students
who went to big engineering “factories” where they didn’t care if you have values or
were flexible. I was going to be a complete engineer: technical genius and sensitive
humanist (人文学者) all in one.
Now I’m not so sure. Somewhere along the way my noble ideals crashed into reality,
as all noble ideals eventually do. After three years of struggling to balance math, physics
and engineering courses with liberal-arts courses, I have learned there are reasons why
few engineering students try to reconcile (协调) engineering with liberal-arts courses in
college.
The reality that has blocked my path to become the typical successful student is that
engineering and the liberal arts simply don’t’ mix as easily as I assumed in high school.
Individually they shape a person in very different ways; together they threaten to confuse.
The struggle to reconcile the two fields of study is difficult.

Passage Three
Questions 31 to 35 are based on the following passage.
Priscilla Ouchida’s “energy-efficient” house turned out to be a horrible dream. When
she and her engineer husband married a few years ago, they built a $100,000,
three-bedroom home in California. Tightly sealed to prevent air leaks, the house was
equipped with small double-paned (双层玻璃的) windows and several other
energy-saving features. Problems began as soon as the couple moved in, however.
Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and
could hardly sleep. It was as though she had suddenly developed a strange illness.
Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas
in her kitchen was twice the maximum allowed by federal standards for chemical workers.
The source of the gas?
