Text{{/B}} Researchers stress that we need diet and exercise to
drop pounds. "The most {{U}}(26) {{/U}} way to lose weight is with a
combination, "says Rend Wing, head of the National Weight Control Center.
{{U}}(27) {{/U}} experts also admit that many {{U}}(28)
{{/U}} losers find it helps to {{U}}(29) {{/U}} on one or the other.
"A lot of people feel helpless at the thought of {{U}}(30) {{/U}}
everything--diet, lifestyle," says Bess Marcus, professor of human behavior at
Brown University Medical School. "So ask yourself. '{{U}} (31) {{/U}} do
I want to start? What am I willing to focus on?'" The
{{U}}(32) {{/U}} depends on everything from what you hope to
{{U}}(33) {{/U}} to how your life is {{U}}(34) {{/U}} If you are
in a big hurry to drop pounds {{U}}(35) {{/U}}, dieting is the way to
go. Decades of {{U}}(36) {{/U}} have shown it's the surest and quickest
method. If you are more {{U}}(37) {{/U}} with how you look than with
numbers on the scale, though, {{U}}(38) {{/U}} may be the way to go. By
increasing physical activity, you'll {{U}}(39) {{/U}} fat and build
muscle tissue. {{U}}(40) {{/U}} often end up losing both fat and muscle
tissue. Your {{U}}(41) {{/U}} approach is one that suits
your lifestyle. If you've tried and {{U}}(42) {{/U}} at one
approach, consider the other. "A lot of people have become so disappointed that
they begin to think they'll {{U}}(43) {{/U}} be able to lose weight,"
says Marcus. "That's when it's time to try something new. {{U}}(44)
{{/U}} a small step forward can help people {{U}}(45) {{/U}}
confidence and convince themselves they can make even bigger
changes."
【答案解析】[精解] 本题考查对上下文语义的综合理解。insist on坚持，坚决要求；dwell on细想，详述；concentrate on集中，全神贯注于；stress on着重，强调。前文说到“with a combination”，指的是把节食和做运动结合起来。由上题可知后面的意思与前文相反，所以应该是说把注意力集中在其中一种方法上。故选C。
【正确答案】
C
【答案解析】[精解] 本题考查动宾搭配。develop发展，建立；combine结合；change改变；practice练习；combine常用于combine A with B/combine A and B结构，故应排除。此空后面所接宾语 everything的指代对象是“饮食，生活习惯”，饮食和生活习惯只能是“改变”而不可能是“发展或者练习”。故选C。
