Passives

In passives the subject of active voice becomes the agent and the object of active voice becomes the subject. In addition, the verb phrase has an extra be-verb. The agent of passive voice is often deleted. Let's lake at a few examples:

Mrs. White scolded Mrs. Black.

In this example the subject is Mrs. White and the object is Mrs. Black. Let's passivize the sentence:

Mrs. Black was scolded by Mrs. White.

Now the object of the first sentence is the subject and the subject of the first sentence is the agent. The agent is found in a prepositional phrase with the word by.

We can say that the subject of active voice is demoted to agent in passive voice. Likewise, we can say that the object of active voice is promoted to subject in passive voice.

Here's another example:

William Shakespeare wrote Romeo and Juliet.
Romeo and Juliet was written by William Shakespeare.

Here William Shakespeare is the subject of active voice and the agent of passive voice. Romeo and Juliet is the object of active voice and the subject of passive voice.

This is our last example:

He is painting the house brown.
The house is being painted brown.

In this case the agent of passive voice isn't expressed. We see the object of active voice (the house), which is the subject of passive voice. In active voice we have a present continuous verb, and in passive voice we have a present continuous passive which adds a be-verb to the verb phrase.

Passives have a subject and agent, but the agent is often deleted. In passives the subject of active verb assumes object position and the object of active voice assumes subject position. With respect to verbs, passives have one more be-verb.

Great Math Trick

There's a great math trick for multiplying numbers. For this trick to work the numbers must start with the same digit and the last digits must add up to ten.

Let's look at an example. The first example is 44x46. Here the two numbers start with the same digit, which is 4. Their last two digits, 4 and 6, add up to 10. What we must first do is add a 1 to 4 and multiply. 5x4=20, so the first number that we write is 20. Next we have to multiply the last two digits, 4 and 6. 4x6=24, so we write 24. Now we have our answer. 44x46=2024.

Let's look at another equation. We can add 88x82. These two numbers also start with the same digits and the last digits add up to 10. 9x8=72 and 8x2=16. This gives us our answer. 88x82=7216.

With 21x29, we first write 6 because 3x2=6. 9x1=9, but we need two digits so we write 09. 21x29=609.

This math trick also works with numbers greater than two digits. Let's use the example of 103x107. 10x11=110, so we write this down. 3x7=21, so we write this down also. Now we have our answer. 103x107=11021.

When two numbers start with the same digit and their last two digits add up to ten, there's a math trick we can use to quickly multiply the two numbers. We simply add one to the first digit and multiply. We write this down and then multiply the last digits of each number and write this down as well. Knowledge of this math trick is very useful for multiplying numbers quickly in our heads.

Victory with a Rook Sacrifice

In a game of speed chess vs. 5k1991 of Poland, I won with a rook sacrifice. My opponent played white. Here are the moves of the game with my analysis:

1. e4 c5
2. Nf3 Nc6
3. d4 cxd
4. Nd4 e5

Here I usually play e6 or d6, but this time I decide to play a different move.

5. Nb3 Bb4+
6. Bd2 Bxd2+
7. Qxd2 Nf6
8. Nc3 0-0
9. f3 a5
10. a4 Nb4

My knight has a nice square on b4.

11. h4 b6
12. h5 d5
13. exd Nfxd5
14. 0-0-0 Bb7
15. h6 g6
16. Nxd5 Bxd5
17. Na1 Qe8

White doesn't want to allow Bxb3 because this weakens the pawn shield around his king.

18. Bb5 Qe6
19. Qg5 f6
20. Qe3 Rfc8
21. c3 Rc5

White attacks my knight, but my knight is safe because the white pawn cannot capture due to the pin on the white king by my rook.

22. Rxd5 Nxd5

White makes a mistake. He wants me to play Rx5 so he can eliminate my knight with cxb4. He overlooks the capture with my knight.

23. Qe4 Rac8
24. c4 Nb4
25. Nb3 Rxc4+

White makes another mistake. He fails to see that I can sacrifice my rook to win his queen. A better move is b3.

26. Bxc4 Rxc4+

White resigns because I win his queen. In this exciting game white overlooks my knight capture on move 22 and my rook sacrifice on move 26. These two moves are the keys to victory in the game.

English Nouns With Identical Singular and Plural Forms

Most English nouns have the plural suffix -s or -es. Some plurals such as children, men and women are irregular. However, there are a few which are identical in both singular and plural. Here is a list of such nouns:

aircraft antelope bass bison carp
cod deer elk fish grapefruit
moose offspring salmon sheep series
shrimp trout tuna won yen

For the noun fish the plural fishes is also possible, but this form isn't so common and can be considered archaic. In the case of shrimp, many British English speakers use the form shrimps.

Many of these invariable nouns are types of fish, i.e., carp, salmon, tuna and names of animals, i.e., deer, moose, sheep. They can also be the names of currencies such as won and yen. The word fruit has the plural fruits, but in the compound grapefruit the noun is invariable in number.

A few English nouns are invariable in singular and plural. Many of these nouns are names of animals, fish and currencies. These nouns with identical singular and plural forms are known as invariable nouns.

Initial Stress-Derived Nouns

A number of English nouns are derived form verbs. Though these nouns have the same spelling, they are stressed different from their verbs. The nouns are stressed on the initial syllable, but the verbs are not. Here's a list of initial stress-derived nouns:

combat compound conflict contrast decrease
discount export extract import increase
insult perfect permit rebel refill
refund transplant update upgrade upset

In a few of these words, stress isn't the only difference between the noun and the verb. In combat, compound, conflict, contrast, perfect, and rebel, there's also a difference in pronunciation. For example, the first syllable of combat has a reduced vowel when the word is a verb. When combat is a noun, the first syllable has a full vowel. In compound, many speakers pronounce the first syllable with a reduced vowel when this word is a verb. This reduced vowel is also audible in the first syllables of the verbs conflict, contrast, perfect and rebel.

The words abuse, excuse and use are similar in the sense that they are both nouns and verbs. However, they are stressed the same. The difference is in the pronunciation of the final consonant. The nouns are pronounced with a word-final /s/ and the verbs with a word-final /z/.

English has many nouns which are derived from verbs and share the same spelling. However, they are stressed differently. The nouns are stressed on the initial syllable and the verbs on the final. Another category concerns nouns and verbs which share the same stress and spelling but differ in the pronunciation of the final consonant.

CV Analysis of English Numbers

The English numbers from one to ten can be analyzed with respect to their consonant and vowel sequences. With the exception of seven, they're all monosyllabic. Let's examine their CV sequences.

Here are the numbers with their respective CV sequences:

one CVC
two CV
three CCV
four CVC (CV for non-rhotic speakers)
five CVC
six CVCC
seven CV.CVC
eight VC
nine CVC
ten CVC

In an analysis of the English numbers from one to ten, we can make a few observations. We have eleven syllables because the number seven is disyllabic. Of these eleven syllables, we have the following CV sequences:

CVC (6)
CV (2)
CCV (1)
VC (1)
CVCC (1)

The most common CV sequence is CVC. The other CV sequences are far less common. We have a complex onset in only one word, three, and a complex coda in six.

90% of the numbers from one to ten are monosyllabic. Most have simple onsets and simple codas. The CVC sequence occurs in more than half of the syllables. It appears that the CVC sequence is very common in English syllables.
