單選題

We can now watch electricity as it flows through even the tiniest circuits. By scanning(掃描) the magnetic field(磁場) generated as electric currents flow through objects, physicists have managed ________.

A、to picture the progress of the currents

B、of detecting a current as weak as 10 microamperes

C、to making chips any smaller

D、to scan microchips for faults

【正確答案】 A

【答案解析】 manage to V.是“設(shè)法做成”的意思。picture在此是動(dòng)詞，“to picture the progress of the currents”意思是“繪出電流運(yùn)行圖”。即：物理學(xué)家們通過掃描電流通過物體時(shí)產(chǎn)生的磁場而繪出電流運(yùn)行圖。
