[填句補(bǔ)文] Although the researchers have only just made the technical details of the microscope public， it is already on sale. It is currently the size of a refrigerator and takes several minutes to scan a circuit， but Xiao and Schrag are working ________.

A.to take tiny chips we require

B.to making chips any smaller

C.to shrink it to the size of a desktop computer and cut the scanning time to 30 seconds

D.of conducting electricity

正確答案：C

答案解析：這部分所說(shuō)的體積的減小和所需時(shí)間的縮短恰好與前半句中提到的冰箱大小的體積和所需數(shù)分鐘的時(shí)間形成了對(duì)比。即：目前它大約像冰箱那么大，而且要用幾分鐘掃描一個(gè)電路，但是他們正在努力使它縮小到臺(tái)式計(jì)算機(jī)那么大，把掃描時(shí)間縮短到30秒。

2、單選題

[閱讀選擇]You can't change your energy cycle， but you can learn to make your life fit it better. Habit can help， Dr. Kleitman believes. Maybe you're sleepy in the evening but you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day， rise before your usual hour. This won't change your cycle， but you'll get up steam and work better at your low point.

If one wants to work more efficiently at his low point in the morning， he should _______.

A.change his energy cycle

B.overcome his laziness

C.get up earlier than usual

D.go to bed earlier

正確答案：C

答案解析：本題要求讀者找出本段中的最后兩句，并聯(lián)系本段開(kāi)頭兩句的意思，作出正確判斷。本段開(kāi)頭說(shuō)，“雖然你無(wú)法改變自己的能量周期，但你可以使你的生活適合這一周期。Dr. Kleitman認(rèn)為經(jīng)常性的行為(對(duì)你的能量周期)能起作用。”最后兩句又說(shuō)，“…rise before your usual hour…work better at your low point.”(“如果你在上午處于能量的低潮，但你有重要的工作要在上午做，那么你就要比平時(shí)早起。這并不改變你的周期，但你可以在低潮時(shí)得到能量，工作得更好。”)因此選項(xiàng)C是正確答案。
