分析 在你做選擇之前，要確保你已經(jīng)核對(duì)了這一頁(yè)上的信息．

解答 答案：D．根據(jù)Make sure you have checked the information in the passage可知核對(duì)了這一頁(yè)上的信息要發(fā)生在you make the choice（做選擇）之前，所以答案是D before"在…之前"．其他選項(xiàng)的含義分別是A"在…之后"；B"自從"；C"當(dāng)…時(shí)候，然而"．

點(diǎn)評(píng) 考查從屬連詞．before的固定句型：
1．用于句型"it was not long+時(shí)間段+before …"意為"不久就…．"
It was not long before he sensed the danger of the position．
2．用于句型"it will be（not ）+時(shí)間段+before…．"表示"要過(guò)多久/不久…才…"

7．Hi guys!I'm Lucy the Ladybird and while I'm very much of a lady，I'm not actually a bird but a glowing red beetle（甲蟲(chóng)） with decorative black spots．
    I'm a friendly little bug，to be honest，and simply like to be close with my pals as long as they handle me very gently．I don't bite humans but I do sink my teeth into mean beasts like aphids （蚜蟲(chóng)） which，unlike me，are very harmful to all the plants．I milk the aphids just like people do with cows and I milk them dry of all the sap （汁） they have got from your poor plants．I'm a real gardeners'friend and love helping out around the place by pollinating flowers，tidying up plants'fallen leaves and helping to turn them into nice rich fertilizer to feed everything both above and below the soil，and naturally，being so attractive to look at，we are perfect living garden decorations．
   One thing I can not tolerate is all that poisonous pollution from vehicles，garbage burning and other un-environmentally friendly acts that occur in the cities every single minute of the day and night．Pollution of any kind really chokes me to death，so these days，I only live in clean countryside areas，particularly cool ones where it rains and everything grows fresh and green from spring right through to autumn．In winter，when the weather is too cold for me to bear，then I find a nice place to sleep until the snow has gone and I can come back out to play．
   Oh!I almost forgot to tell you that although I am not a bird I do have wings and can fly for short distances．So if you pick me up and let me run up and down your hands and arms，then please don't frighten me by screaming if I suddenly secede to take off!
