Sentence patterns
1. The speaker's supposed to be excellent. 演講人應(yīng)該是一流的吧。
suppose是“猜想、認(rèn)為”的意思。常常用于不定式復(fù)合結(jié)構(gòu) suppose sb./sth. to be，表示“認(rèn)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(rèn)為怎樣”、 “應(yīng)該”。如：Harry Potter is supposed to be one of the best films. We are not supposed to play football on Sundays. 不準(zhǔn)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(qiáng)。
need 表達(dá)“某人/物需要被……”時，后面要跟動詞不定式的被動語態(tài)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。

over在這里是“距離長達(dá)……”的意思，在這里相當(dāng)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(qū)域中，在這里good相當(dāng)于程度副詞very。掌握這些搭配: stay over the holidays 一直呆到假期結(jié)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(tǒng)治一個王國; speak to sb. over one's shoulder 轉(zhuǎn)過頭去和某人說話; friends over the sea 海外的朋友; work over night 通霄工作

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。

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。

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(diǎn)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(shí)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(dǎo)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(qū)別，同位語從句對前一名詞做補(bǔ)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)
