我国出版的一些语法书和用法书,以及一些有关文章,多把像There is a man wantsto see you这样的句子说成是“只限于土俗口语中使用”的结构。教科书对它“疾恶如仇”,学生无意地用上它,就要算大错而特错。笔者认为有必要“正本清源”。...我国出版的一些语法书和用法书,以及一些有关文章,多把像There is a man wantsto see you这样的句子说成是“只限于土俗口语中使用”的结构。教科书对它“疾恶如仇”,学生无意地用上它,就要算大错而特错。笔者认为有必要“正本清源”。 这种句子结构。展开更多

There is someone at the door. 二、there+be有时和used to连用,表示过去经常存在的一种情况。如:展开更多

However, only a few studies evaluate the association between thyroid hormone levels and neuropsychiatric manifestations in patients with AD. This study aimed to investigate the relationship of thyroid hormone levels and neuropsychiatric symptoms in euthyroid patients with AD. Methods Forty patients with AD （26 women and 14 men）, with no prior AD treatment within 4 weeks before study entry, were evaluated on their thyroid status （total triiodothyronine （TT3）,total thyroxine （TT4）, and thyroid-stimulating hormone （TSH）, cognition （Mini-Mental State Examination （MMSE） and Alzheimer＇s disease Assessment Scale-Cognitive Subscale （ADAS-cog）, neuropsychiatric symptoms （Neuropsychiatric Inventory （NPI） and depression （Hamilton Rating Scale for Depression （HAMD17）. The unique relationship between thyroid hormones and cognitive function and mood was examined with multivariate linear regression analyses. The thyroid status between the neuropsychiatric symptoms group and the non-neuropsychiatric symptoms group was examined with independent-samples t-test. Results In euthyroid AD patients with agitation and irritability has lower TSH serum level than those without these symptoms （t=-2.130, P 〈0.05; t=-2.657, P 〈0.05）; and core score of HAMD is significantly associated with the serum level of TSH （β=0.395, P 〈0.01）. There is no significant association between thyroid hormone levels and cognition （MMSE, ADAS-cog and its subscale score）.展开更多
