8 易混辨析：delay，put off 在表示“推迟某事”时可以互换。 e.g. The flight was delayed / put off due to the bad weather. 由于天气不好，航班被推迟了。

9 但它们又有细微差别： 1) delay强调因某种困难或障碍厌恶，动作主体是人或困难本身，延迟的时间不确定，也可能无限延迟。 e.g. My grandma fell ill all of a sudden, which delayed our trip. 奶奶突然病倒了，延迟了我们的 旅行。

10 2) put off强调“拖延时间”，指因客观原因造成的拖延或主观上的有意拖延。
e.g. You’re always putting off things. You should get rid of this bad habit. 你做事总是拖拉，你得克服这个坏 习惯。

14 易混辨析：distribute, divide
都有“分配”的意思。 distribute指“将某物分成一定的部分或数量，通常各份的数量不一定相等，然后分给某些人或地方”。 e.g. distribute leaflets 分发传单 divide指“把整体分成若干部分”。 e.g. divide it into two 把它分成两份

15 Fill in the blanks. 这笔款项是在本地区的学校中分配的。 2) 一个句子可以划分成有意义的各个部分。 The money ____________________ schools in the area. was distributed among A sentence can ________________ meaningful segments. be divided up into

18 难句解析 1. John Logie Baird constructed the
first color TV in 1928, but it was not until 1938 that the first color TV programmer was broadcast.

19 【分析】 句中but后面的it was not until 1938 that是强调句型，对时间状语not until 1938 加以强调。 句意：约翰· 洛吉· 贝尔德于1928年制造出第一台彩色电视机，但直到1938年第一个彩色电视节目才播出。

20 2. However, most people still benefit
from satellite TV, as local TV companies broadcast the signals they get from satellite receivers to the population living nearby. 句中as引导一个状语从句，在此句中， they get from satellite receivers是定语从句，修饰前面的the signals。

21 句意：然而，大多数人仍然受益于卫星电视，因为当地的电视公司把从卫星接收器接收到的信号传送给附近的居民。

22 3. It all began in 1877, when Thomas
Edison made the first recording of a human voice on his invention, the record player. 句中when引导非限制性定语从句，在此从句中the record player是his invention的同位语。

23 句意：一切始于1877年，这一年托马斯· 爱迪生用他发明的留声机第一次录制了人的声音。
