In Unit 16 of New Concept English 1B。we learn about the

"There be" XXX.

The "There be" sentence pattern is used to express the

existence of a person or object in a XXX singular nouns。we use

"There is" + the noun + in/at/on + the place。For plural nouns。we use "There are" + the noun (in plural form) + in/at/on + the

place。It's important to note that "There be" expresses existence。while "have" and "has" express ownership.

To form a negative sentence。we add "not" after "There be"

and before the subject。For example。"There are not any students

in the classroom." To form a n。we use the auxiliary verb "be"

before "there"。For example。"Are there any children in the

classroom?" XXX is "Yes。there are" and the answer to a negative

n is "No。there are not."

When XXX "There be" sentence。we use the subject closest

to the verb to determine the verb form。For example。"There is

an apple and a banana on the table" and "There are three chairs and

two desks in the classroom."

Moving on to singular and plural nouns。they refer to people。objects。time。places。and abstract concepts。To form the

plural of regular nouns。we add "s" or "es" to the end of the word。For words ending in "s"。"x"。"ch"。or "sh"。we add "es"。For

words XXX followed by "y"。we change the "y" to "i" and add

"es"。For words ending in "f" or "fe"。we change the "f" or "fe"

to "v" and add "es"。For words ending in "o"。we add "es" for

living things and "s" for non-living things.

There are some irregular plural forms。such as "men" for

"man"。"women" for "woman"。"geese" for "goose"。"teeth" for

"tooth"。and "feet" for "foot"。It's also important to note that

some words ending in "o" take "es" in the plural form。such as

"potatoes" and "tomatoes".

"many" or "much." Therefore。the subject-verb agreement is

based on the number of the noun after "of," not on "lot" or "lots."

has been wasted," while "A lot of people have been present" means

"Many people have been present." "Lots of" can also mean

"much," as in "There is lots of time to spare."

XXX。"lot of" cannot be used XXX with "a lot of."

much," while "I know a lot about China" means "I know a great

deal about China."
