|采纳率95.7%前面已经有两位回答的很好了.
不过我觉得问这个问题的人可能是谓语动词和非谓语动词的事情没有弄清楚.所以我再啰嗦几句.
在英语的简单句中,通常都会有一个主要的动词来作为整个句子的谓语,这时候它会发生语态和时态的变化.而其他不充当谓语的动词就被叫做非谓语动词.非谓语动词只有四种形式:不定式,动名词,过去分词以及现在分词.
你举的这个句子主要意思是“这台机器是很受欢迎的”.所以“was”就是主要动词,即整个句子的谓语,所以发生了时态的变化.
而“去年被发明”就是修饰限定机器的成分,叫做后置定语.所以invent并不是句子的谓语,而是非谓语动词,所以这里只用了过去分词来表示“被发明”,而没有加was做成完整的被动语态.1年前查看全部

- (C)The car was invented over a century ago.You may know all
(C)
The car was invented over a century ago.You may know all kinds of cars’ names,but many people don’t know who was the inventor(发明者)of the first car.
The first car was invented not by an Englishman,but by an American.His name was Henry Ford.
Henry was born in a poor family.He was the eldest of six children.When he was a boy,he became interested in watches and machines.When he was twelve years old,his mother died.Soon he had to work in a machine shop for two dollars and fifty cents a week.The hard life made him strong and able.
At that time,there was another interest in the life of the young Ford.He wished to make a machine.It could run without a horse,so it was named horseless carriage(马车).He overcame(克服) a lot of difficulties and in April 1893,the “horseless carriage” was invented at last.It was the first car.
Later,Henry Ford founded the Ford Motor Company.He was really the first inventor of car in the world.
Answer the questions:
Who really invented the car first?

Invented some 60 years ago,computers have already transformed the way most of us live.The advent of the Internet opens up the possibility of communicating and interacting via the computer.
1,invented some 60 years ago这是不是属于过去分词作状语?那这句“Invented some 60 years ago,computers have already transformed the way most of us live.”属于状语从句吗?
2,分词作状语到底是什么意思呢?状语不是应该放在主语之后,谓语中心词之前吗?怎么理解粉刺作状语呢?
3,Invented some 60 years ago这句话中加了一个some是什么意思呢?

|采纳率100%先翻译一下大概的意思:如果当时就有这种检验方法的话,现在街上的很多人早就为他们的犯罪行为付出代价了.
以下是句子分析:
这句话是一个虚拟语态的句子,表示对某种情况的假设,在这里是对过去情况的虚拟条件句.
表示过去情况的虚拟条件句结构如下:
谓语的主要形式为,从句:had+过去分词;主句:would have+过去分词.
来看一个经典例题
Had he worked harder,he _______ the exams.
A)must have got through
B)would have got through
C)would get through
D)could get through
正确答案为B).条件句为虚拟语气的倒装句,正装顺序为If he had worked harder,我们可以看出这是had+过去分词,表示同过去情况相反,则主句应该为would have+过去分词got,因此应当选择B).
在我的个人网站里有更详细的说明,包括对现在和将来时态进行假设的虚拟语气句.有需要可以来看看.1年前查看全部

|采纳率100%An abacus, also called a counting frame, is a calculating tool used primarily in parts of Asia for performing arithmetic processes. Today, abaci are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moved in grooves in sand or on tablets of wood, stone, or metal. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Japan, Africa, India and elsewhere.
The user of an abacus is called an abacist; he or she slides the beads of the abacus by hand.[1]
The earliest known written documentation of the Chinese abacus dates to the 14th century AD.[13]
The top of the abacus is called the heaven and the bottom is called the earth.[14]
The Chinese abacus known as the suànpán is typically 20 cm tall and it comes in various widths depending on the operator. It usually has more than seven rods. There are two beads on each rod in the upper deck and five beads each in the bottom for both decimal and hexadecimal computation. Modern abacuses have one bead on the top deck and four beads on the bottom deck. The beads are usually rounded and made of a hardwood. The beads are counted by moving them up or down towards the beam. If you move them toward the beam, you count their value. If you move away, you don't count their value.[citation needed] The suanpan can be reset to the starting position instantly by a quick jerk along the horizontal axis to spin all the beads away from the horizontal beam at the center.
Suanpans can be used for functions other than counting. Unlike the simple counting board used in elementary schools, very efficient suanpan techniques have been developed to do multiplication, division, addition, subtraction, square root and cube root operations at high speed.
In the famous long scroll Along the River During the Qingming Festival painted by Zhang Zeduan (1085–1145 AD) during the Song Dynasty (960–1297 AD), a suanpan is clearly seen lying beside an account book and doctor's prescriptions on the counter of an apothecary's (Feibao).
The similarity of the Roman abacus to the Chinese one suggests that one could have inspired the other, as there is some evidence of a trade relationship between the Roman Empire and China. However, no direct connection can be demonstrated, and the similarity of the abaci may be coincidental, both ultimately arising from counting with five fingers per hand. Where the Roman model (like most modern Japanese) has 4 plus 1 bead per decimal place, the standard suanpan has 5 plus 2, allowing use with a hexadecimal numeral system. Instead of running on wires as in the Chinese and Japanese models, the beads of Roman model run in grooves, presumably making arithmetic calculations much slower.
Another possible source of the suanpan is Chinese counting rods, which operated with a decimal system but lacked the concept of zero as a place holder. The zero was probably introduced to the Chinese in the Tang Dynasty (618-907 AD) when travel in the Indian Ocean and the Middle East would have provided direct contact with India, allowing them to acquire the concept of zero and the decimal point from Indian merchants and mathematicians.1年前查看全部
