Sentence patterns
1. The speaker's supposed to be excellent. 演講人應該是一流的吧。
suppose是“猜想、認為”的意思。常常用于不定式復合結構 suppose sb./sth. to be，表示“認為某人/某物怎樣”。本句是這個句子的被動式，即sb./sth. is supposed to be…表示“某人/某物被認為怎樣”、 “應該”。如：Harry Potter is supposed to be one of the best films. We are not supposed to play football on Sundays. 不準我們在星期日踢足球。You're supposed to ask the teacher if you want to leave the classroom.
2. They need to be strengthened every 3-4km. 因此，每隔3-4公里，信號就得增強。
need 表達“某人/物需要被……”時，后面要跟動詞不定式的被動語態need to be done，或動名詞need doing (包含了被動的含義), 如: The windows need cleaning. 或The windows need to be cleaned. 窗子需要擦了。I think these potatoes need to be cooked a little longer. 或need cooking 類似的詞還有demand, require, want等。
Language tips

hold on 是“不要掛斷電話”。如：Hold on a minute.等一會兒。
2. At the beginning it was difficult to hear people over long distances. 開始很難聽到遠方的人講話的聲音。
over在這里是“距離長達……”的意思，在這里相當于through，表示在空間上的跨越。例如：
drive over a road 沿著道路一直開下去；over a good distance.在一長段的區域中，在這里good相當于程度副詞very。掌握這些搭配: stay over the holidays 一直呆到假期結束; can't tell you over the phone；不能通過電話告訴你; chat over coffee 喝著咖啡聊天; Think the problem over 全面地思考這個問題; rule over a kingdom 統治一個王國; speak to sb. over one's shoulder 轉過頭去和某人說話; friends over the sea 海外的朋友; work over night 通霄工作
3. In those days, to make a call, you had to wind a handle at the side of your telephone. This produced enough electricity to make your call. 那時，你要打電話就得轉動電話機旁的搖柄，才會產生足夠的電供你打電話。
wind做動詞，發音是[waind]，它的過去式和過去分詞都是 wound, 讀作[waund],意思是“彎曲、蜿蜒”或者“纏繞”、“轉動、上發條”的意思。如：wind a wool into a ball把羊毛繞成球; Have you wound your watch? 表上發條了嗎？The path winds s (its way) through the woods. 這條路蜿蜒穿過樹林。下一句是什么意思？A gentle wind was blowing through the trees.
4. The operator connected the two numbers and made a note of the length of the telephone call and the charge. 接線員把兩個號碼接通然后記下通話的時間和電話費。
make/take a note of… 是“記關于……的筆記”，如：make note of the lecture；做講課的筆記; Please make a note of my new address. 請把我的新地址記下來。took notes during the lecture 上課做筆記 區分: take note of 注意；發現
6. The problem with electrical signals is that they get weaker and weaker as they travel along metal wires. 電信號有一個難題，就是當其沿著金屬導線傳送時，信號就會變得越來越弱。

7. Light signals, however, can travel 150 km without getting weaker, and their signal is clearer too. 然而，光信號卻可以傳輸150公里而不減弱，而且光信號也比較清晰。
however在句中的位置比較靈活，可以放在句首、句中或句尾：多或少However I'll do it in my own way. 可是，我將照我自己的方式去做。Later, however, he made up his mind to do that.可是，后來他就下定決心去做了。He said it was so, he was mistaken, however. 他說事情就是那樣，不過他錯了。一般but只位于句首。
8. You can take it with you wherever you go, for example, when you go for a meal in a restaurant. 無論你走到哪里，例如去飯館吃飯，你都可以帶著它。
wherever you go 中的wherever是連詞，作“無論何地”，“不管…在哪里”解，引起一個表示讓步的狀語從句，例如：Wherever he goes, I'll go with him. 不論他走到哪里，我都跟他走。I will find her wherever she may be. 不管她可能在什么地方，我總會找到她的。
9. One new model has lately been developed for business people. 最近還為商務人員研制了一種新式機型。
lately意思是recently，作“近來”解，句子的謂語動詞常用完成時，如: I haven't seen him lately.

10. You can record up to 20 different names with their telephone numbers on this kind of phone. 在這種電話機上你可以錄下20個不同的姓名和他們的電話號碼。
up to是“直到……，達到……”的意思，表示截止到什么數量或時間為止。例如：up to this time 直到此刻。up to常在表示時間的句子中，如：The family had lived in this house up to the 19th century. 這家族在這棟房屋中一直住到19世紀。up to還可以表示物理位置上的“直到”，例如：The snow came up to my knees. 雪集到了我的膝蓋。
Grammar
名詞性從句包括主語從句、賓語從句、表語從句和同位語從句。有幾點要注意：
⑴that在句首不可省去: That he will come and help you is certain. 他來幫助你是確實無疑的。
⑵主語從句表語從句和同位語從句中只能用whether不可用if : He must answer the question whether he agrees to it or not. 他必須回答他是否同意此事這樣一個問題。
⑶主語從句放在句首，句子常顯得笨重，因此一般把它移到句子后面，前面用引導詞“it”來作形式主語: It is known to us how he became a writer. 我們都知道他是如何成為一名作家的。
⑷whether常與or not連用，不能用if代替, 另外作介詞賓語要用whether不能用if: Everything depends on whether we have enough money. 一切要看我們是否有足夠的錢。
⑸同位語從句注意與定語從句區別，同位語從句對前一名詞做補充說明，that在從句中無語法位置，而定語從句所修飾詞在從句中占一語法位置：The idea that one can do the work without thinking is wrong．(同位語從句)The idea that you put forward at the meeting is wrong．(定語從句)
