18．It was 5o'clock ______ the front doorbell opened..（　�。�
A．thatB．whenC．whatD．in which

分析 五點(diǎn)時(shí)，前面的門鈴響了．

解答 答案：B句中the front doorbell opened不能構(gòu)成對(duì)5 o'clock的修飾或強(qiáng)調(diào)，不是強(qiáng)調(diào)句型或定語從句；it指時(shí)間，是句子的主語；the front doorbell opened在句中作時(shí)間狀語，是一個(gè)狀語從句，意思是當(dāng)前面的門鈴響時(shí)，當(dāng)時(shí)的時(shí)間是五點(diǎn)．故選B．

點(diǎn)評(píng) 時(shí)間狀語從句是副詞性從句的一種，在句中作時(shí)間狀語，修飾句子的謂語或整個(gè)句子內(nèi)容．

6．How Safe Is Your Bed？
Do you consider your bed a safe place of rest and calm？Do you sink into a mattress （床墊） after a hard day's work and feel tension and stress drain away as you rest your weary head on a soft pillow？Well，you might not feel so relaxed if you knew that tiny pests were hiding there!It seems that beds may not be such a good place for our health and happiness----they could actually be making us ill!
Recent studies have shown that bacteria，fungi and dust mites （螨蟲），some smaller than the diameter of a hair，live in our bedding．When we move around in our sleep，we disturb them and they are bounced up into the air--which we then breathe in as we sleep．According to the American Lung Association，four out of five households in the United States now have high levels of dust mites，although it's not the mites themselves that cause the problems，but their droppings．These are"highly allergenic （致敏的）"according to Dr William Berger，a fellow with the American Academy of Allergy，Asthma and Immunology．"Even if you aren't allergic…they can still irritate you，the way pepper would if it blew into your nose and eyes．"
Brendan Boor，Assistant Professor of Civil Engineering，who carries out bed research，also found that bed dust in the air leads to allergies--causing watery eyes，sneezing，coughs and asthma．He has recommended ways to limit our exposure to these boring allergens：
Firstly，he suggests vacuuming your mattress regularly-weekly，or even daily．He also recommends doing away with carpets and washing floors．Using allergen-proof bed covers，he says，can reduce the risk of getting allergies．In addition，washing bedding and pillows frequently can help，as can a portable air cleaner placed near the bed．
If you do as Brendan Boor suggests，you will breathe in cleaner air as you sleep …or will you？Is it really safe for you to go back in your bed？
Studies show that beds aren't a good place for your well-being and they can even make you sick．Mites，bacteria and other tiny living things in your beds can cause illness or irritate you．Therefore，experts suggest that cleaning carpets，washing floors，using allergen-proof bed covers，and washing bedding and pillows frequently can make your bed safe．．
