It can travel easily through our 8 ( body), because electricity moves 9 (quick) through water and the human body is 70% water! What will happen if you get shocked(触电)? You will find it hard to breathe; your heart will stop 10 (beat) and you will get burns and even die! As ...
例如在“All living cell send out tiny pulses of electricity As the heart beats, it sends out pulses of record; they form an electrocardiogram, which a doctor can study todetermine how well the heart is working”这里的“it”指代的是“the heart”,“they”指代的是“the pulses of record”。
The living world holds many interesting secrets of electricity. Scientists are discovering more and more on electricity in order to benefit human.Do you know all living cells send out tiny pulses of electricity? As the heart beats, it sends out pulses of record; they form an electrocardiogram(...
Moreover, electricity is also very important in education. We use computers and printers to help us with our studies. They help us learn and work more efficiently. In addition, electricity is also used in hospitals. Medical equipment such as X-ray machines and heart monitors require...
