分析 ---你覺得要過多久我們才會(huì)知道面試的結(jié)果？
---大約一個(gè)月．

解答 答案：B
分析句子結(jié)構(gòu)可知，該問句符合"It+（will ）be+時(shí)間段+before …"的結(jié)構(gòu)； 意為："過了多久才…"；本句的意思為：要過多久我們才會(huì)知道面試的結(jié)果；故選B

點(diǎn)評(píng) 本題考查從屬連詞before的用法：
1．before 作從屬連詞時(shí)，意為"在…之前，還沒來得及…就"；She left the company before I could have a word with her．2．用于句型"it be+時(shí)間段+before …"表示"過了多久才…"It will be half a year before you graduate from this school；3．趁…（還沒有）；Do it before you forget it．
另外，還應(yīng)注意until與before的區(qū)別：before 在…之前；比…早些；強(qiáng)調(diào)時(shí)間先后關(guān)系；until在…以前；直到…時(shí)；當(dāng)主句是肯定句時(shí)，表示主句動(dòng)作的終止時(shí)間；主句是否定句時(shí)，強(qiáng)調(diào)主句動(dòng)作的起始時(shí)間．

16．"Sleep-disordered breathing"is a term for a group of conditions that can interfere with nornlal breathing while people sleep．These include snoring，mouth-breathing and sleep apnea（窒息）．Sleep-disordered breathing can do more than just leave people feeling tired the next day．It can also affect people's health．In children the effects can include behavioral and emotional problems．
In a new study．1ed by Karen Bonuck at the Einstein College of Medicine．researchers asked parents about their children's breathing from when they were babies up to about age seven．The study finds sleep-disordered breathing is associated with a fifty percent increase in outcomes including hyperactivity（多動(dòng)癥），aggressiveness and problems relating to other children．
Ms．Bonuck says the more serious the breathing problems，the more serious the behavioral issues were likely to be．Other studies have：linked sleep with children's behavior，but this study was extensive enough to：reject other possible causes．
How well do you sleep？A popular belief is that sleep gets worse with age．But．in another new study，those who reported the fewest problems with the quality of their sleep were people in their eighties．
Researchers did a telephone survey of American aduhs．Michael Grandner at the University of Pennsylvania medical school says the original goal was to confirm that aging is connected with increased sleep problems．The survey did find an increase during middle age，worse in women than men．But except for that，people reported that their sleep quality improved as they got older．At least they felt it did．
Mr．Grandner says．"Even if sleep among older Americans is actually worse than in younger adults，feelings about it still improve with age．"
In the study，health problems and depression were linked with poor sleep．But，based on the study．Mr．Grandner says older people who are not sick or depressed should be reporting better sleep．"If they're not．they need to talk to their doctor．"he says．He says heahtlh care providers generally dismiss sleep complaints from older adults as a normal part of aging．
