疑难解析
1.Mrs.Jones’ house was robbed last night.昨晚琼斯夫人家遭抢劫了。
本句是被动语态,rob是及物动词,意思是“抢劫,盗取”。was robbed是被动语态,它的结构是:be + 过去分词。如果说“抢劫某人的东西”,则用句型:rob sb. of sth.如:
They robbed the bank last night. 昨晚他们抢劫了银行。
The robber robbed the man of his money. 强盗抢走了那人的钱。
The woman's bag was robbed by a young man. 那个妇女的包被一个年轻抢走了。
2. Who is the most popular singing star at the moment? 谁是当今最流行的歌星?
the most popular是形容词popular的最高级形式。popular是一个多音节的形容词,多音节形容词的最高级形式不是在其后面加est,而是在其前加most。如:interesting-most interesting,beautiful—beautiful等。
at the moment意为“此刻、现在、目前”。如:
The number is busy at the moment. Try it again in five minutes.您拨打的号码现在忙,请五分钟后再试一次。
3. Maths is as interesting as English. 数学与英语一样有意思。
“as +原级+as…”结构用于两者间的平级比较,意为:“……和……一样”。如:Li Lei is as tall as Wu Ming.李雷与吴明一样高。它的否定形式为:not(so)as…as,意思为:……不如……。如: Han Mei is not as hard-working as Wei Hua. 韩梅不如魏华用功。
4. One afternoon in April 1912, a new ship set off from England to American on its first trip.1912年四月的一个下午,一艘新船从英国出发,开始了去美国的首次航行。
1) set off是“出发”的意思,同义词组为“set out”。如:
She set off for Japan to take part in the World Table Tennis Competition last week. 她上星期去日本参加世界乒乓球比赛。
2) from…to…“从……到……”,它可以修饰地点,如此句中from England to American从英国到美国;也可以修饰时间,如:
Every day he reads from 8 to 11 in the morning, writes from 2 to 5 in the afternoon, watches TV from 7 to 10 at night and then goes to bed. 他每天上午从八点到十一点看书,下午从两点到五点写作,晚上从七点到十点看电视,然后去睡觉。
3) trip(旅行)是名词,它的动词形式为:travel。
5. Please make room for me. 请给我让出点地方来。
make room for somebody / something 意思是“给某人/某物让出空地方”。room在这里是“空间,地方”的意思,是不可数名词,前面不加不定冠词a,“一点儿地方”为a little room,“足够的地方”为enough room。如:
