　　36.E

　　语法判断：exercise后是and，而and前后应为并列结构(又称平行结构)，因为and后为gorging on comfortfood，所以前面也应当是现在分词短语，因此应填入现在分词。备选项中只有shunning是现在分词，因此答案很明确。

　　语义判断：shun：(故意或习惯地)避免;回避，躲开。从语义上判断也是正确的。

　　37.G

　　语法判断：此处应为定语来修饰fmdings，后为by，而过去分词既表示被动又可用作后置宾语，所以此处应填入过去分词。

　　语义判断：备选的过去分词或过去式有reached、highlighted、blamed、released、lost、admitted、treated、dieted、failed，但从上下文语义判断，意思应为：由减重中心XLS医院发布的调查或研究结果，所以应选择released。

　　38.N

　　语法判断：空格前的the是冠词，空格后的majority是名词，因此应当填入定语。

　　语义判断：符合语法条件的词有很多：massive、reached、highlighted、blamed、lost、admitted、treated、dieted、overall、vast、failed，而avastmajority是个近乎固定的搭配，意为“大多数”，故本题选N。

　　39.J

　　语法判断：此句缺谓语，后接一个省略了that的宾语从句。可作谓语的选项有reached、highlighted、blamed、lost、admitted、treated、dieted、failed，根据文章，可知只有admitted符合。

　　语义判断：该句意为：五分之一的节食减肥者承认自己在第四五天的时候就坚持不住了。

　　40.I

　　语法判断：此句主、谓、宾都不缺，而空格出现在were和blamed之间，所以应为状语，因而应填入副词。

　　语义判断：备选的副词有still、also和overall，上文提到了饥饿是人们放弃减肥的原因之一，而此处提到单调乏味和酒精的刺激也是让人们放弃减肥的原因，因而从语义上判断，只有also符合上下文意。

　　41.C

　　语法判断：此句缺谓语，应填入动词，其后接宾语从句。

　　语义判断：备选的动词有reached、highlighted、blamed、lost、treated、dieted、failed，但从上下文语义判断，此处意思应为：国家肥胖论坛医疗主任马特·凯普霍恩博士强调说，仅仅一天不坚持节食就会毁掉一周的努力。highlighted符合此处语法和语义的要求。

　　42.A

　　语法判断：a和590，000之间应该是形容词。

　　语义判断：备选的形容词还有massive和overall，从上下文语义判断massive应为正确选择。

　　43.O

　　语法判断：could already have后应为过去分词。

　　语义判断：备选的过去分词有reached、blamed、lost、treated、dieted、failed。从上下文语义判断，此处的意思应为：调查结果显示，有多达59万人可能已经放弃了新年减肥计划。因而failed是语法判断和语义判断后的最佳选择。

　　44.M

　　语法判断：此句主、谓、宾完整，应填入副词。

　　语义判断：备选的副词还有still和overall。overall意为“总体上，总的来说”，符合此处的语法和语义要求。

　　45.B

　　语法判断：空格前面是they’ve，故后面应接过去分词。

　　语义判断：空格后为targetweight(目标体重)，故按照语义和固定的搭配来进行判断，应为reached，即“达到目标体重”。
