First, is necessary to keep a balanced diet, which is the basis of good health. It is better for us to have more fruit and vegetables everyday. Secondly, it is important to take regular exercises, such as swimming, jogging and so on. Last but not least, it is essential to keep in a good mood. Relaxation and entertainment are ways to renew our spirits and release our stress. When we make healthy habits a part of our everyday life, we are bound to keep healthy. 學(xué)習(xí)記錄卡 3（ Units 13～ 18） （ p2526） 學(xué)習(xí)過程： 輔導(dǎo)訂前完成的學(xué)習(xí)內(nèi)容： A、 √ 做教材中大部分練習(xí) B、 √ 熟悉生詞和詞組 C、 √ 將不懂的地方記錄下來 D、其他 輔導(dǎo)課上的學(xué)習(xí)任務(wù)： A、 √ 聽輔導(dǎo)教師講授 B、 √ 積極參與各項(xiàng)課堂教學(xué)話動 C、 √ 解決疑難問題 D、其他 輔導(dǎo)課后的學(xué)習(xí)內(nèi)容： A、完成剩余的練習(xí) B、 √ 復(fù)習(xí)主要語言點(diǎn) C、自己找一些練習(xí)題進(jìn)一步鞏固所學(xué)內(nèi)容 D、其他 希望輔導(dǎo)教師提供的幫助是： A、答疑解惑 √ B、系統(tǒng)歸納和講解 √ C、有針對性地講解重點(diǎn)、難點(diǎn) √ D、其他學(xué)習(xí)內(nèi)容： 學(xué)習(xí)方法 Units 13～ 18 中主要學(xué)習(xí)了哪些重要的語法項(xiàng)目？ 動名詞與動詞不定式、非限定性定語從句、將來完成時(shí)、現(xiàn)在進(jìn)行時(shí)的被動語態(tài)、現(xiàn)在完成時(shí)的被動語態(tài)、間接引語和間接引語、反意疑問句 這六個單元中我感覺最難或還沒有完全掌握的語言點(diǎn)是： 非限定性定語從句 這六個單元中我最喜歡的話題是： Describe towns 印象最深的 Cultural Notes是： The city 階段性學(xué)習(xí)體會 ：請總結(jié)一下你在這一階段的學(xué)習(xí)情況 。你可以把這一階段你在學(xué)習(xí)中遇到的困難、困惑寫下來，也可以把你的建議想法寫下來跟老師和其他同學(xué)交流。 （略）（一定要自己寫） 作業(yè) 3 （ Units 13～ 18） 第一部分 交際用語 A C A B A 第二部分 英語知識運(yùn)用 二、選擇填空 8.

It is synthesized within the nerve terminal from choline, taken up from the tissue fluid into the nerve ending by a specialized transport mechanism. The enzyme necessary for this synthesis is formed in the nerve cell body and passes down the axon to its end, carried in the axoplasmic flow, the slow movement of intracellular substance (cytoplasm). Acetylcholine is stored in the nerve terminal, sequestered in small vesicles awaiting release. When a nerve action potential reaches and invades the nerve terminal, a shower of acetylcholine vesicles is released into the junction (synapse) between the nerve terminal and the ‘effector’ cell which the nerve activates. This may be another nerve cell or a muscle or gland cell. Thus electrical signals are converted to chemical signals, allowing messages to be passed between nerve cells or between nerve cells and nonnerve cells. This process is termed ‘chemical neurotransmission’ and was first demonstrated, for nerves to the heart, by the German pharmacologist Loewi in 1921. Chemical transmission involving acetylcholine is known as ‘cholinergic’. Acetylcholine acts as a transmitter between motor nerves and the fibres of skeletal muscle at all neuromuscular junctions. At this type of synapse, the nerve terminal is closely apposed to the cell membrane of a muscle fibre at the socalled motor end plate. On release, acetylcholine acts almost instantly, to cause a sequence of chemical and physical events (starting with depolarization of the motor endplate) which cause contraction of the muscle fibre. This is exactly wh
