文法句型

differentiate between X and Y

differentiate X from Y

用法筆記

Often paired with 'between' (to compare two items side by side) or 'from' (to separate one from a broader category). 'Differentiate' sounds more analytical and formal than the everyday phrase 'tell apart', while 'discriminate' can carry unwanted connotations of unfair bias in social contexts.

常見錯誤

Can you differentiate me the two paintings?
Can you differentiate between the two paintings?
💡'differentiate' does not take two objects; use 'between' or 'from'.
I can differentiate the difference between them.
I can differentiate between them.
💡'differentiate' already contains the idea of noticing a difference, so the word 'difference' is redundant.

This feature differentiates this car from others.
💡always use 'from', not 'with', after 'differentiate'.

3.動詞不及物C1
釋義

to change from a simple, unspecialised cell into a more complex cell with a specific job, such as a muscle cell or a nerve cell, during the growth of a living thing

例句

During early development, stem cells differentiate into specialised cells that form the heart and brain.

cells differentiate into [cell type]

Mayumi studies why stem cells differentiate into skin cells rather than nerve cells.

differentiate into X rather than Y

同義詞
  • specialise

    broader term used for any process of becoming adapted to a specific function; not limited to cell biology

反義詞
  • dedifferentiate

    highly technical; the return of a specialised cell to a simpler, unspecialised state

文法句型

cells differentiate into [cell type]

[cell] differentiates to form [structure]

用法筆記

Almost exclusively used in biology and medicine. Frequently occurs in the pattern 'cells differentiate into [specific cell type]'. The noun form 'differentiation' (細胞分化) is equally common in scientific writing. The opposite process is 'dedifferentiation', where a specialised cell returns to a simpler state.

常見錯誤

The stem cell differentiates a heart cell.
The stem cell differentiates into a heart cell.
💡the cell itself changes into something else; use 'into', not a direct object.
Different cells differentiate different jobs.
Different cells differentiate to perform different jobs.
💡'differentiate' describes what the cell becomes, not what it does directly.

4.動詞及物C1
釋義

to use a mathematical process to find the rate at which a function is changing at a particular point, producing a new function called the derivative

例句

In calculus class, Hao learned how to differentiate the function f(x) equals x squared.

differentiate [function]

To find a curve's slope at any point, you must differentiate its equation.

反義詞
  • integrate

    the inverse mathematical operation; integration finds the original function from its derivative

文法句型

differentiate [function]

differentiate [function] with respect to [variable]

用法筆記

Used in calculus and related fields such as physics and economics. The verb is typically transitive, taking a function expression as its object. The noun form 'differentiation' (微分) refers to the process itself, and 'derivative' (導數) is the result.

常見錯誤

Differentiate the function 5 times.
Differentiate the function with respect to x.
💡'times' is not the correct mathematical term; use 'with respect to' to specify the variable.
I differentiated and got the slope.
I differentiated the function and obtained the slope formula.
💡'differentiate' needs an object; you differentiate a function, not just 'differentiate' alone.

differentiate instruction

文法句型

differentiate instruction for [students]

differentiate [subject] by [method]

用法筆記

Common in educational training and pedagogical literature. The noun phrase 'differentiated instruction' (差異化教學) is a standard term in teaching methodology. This usage is distinct from sense 1 in that the teacher is not comparing things but rather adjusting methods to meet varied needs.

常見錯誤

The teacher differentiates the students by level.
The teacher differentiates the lesson for students of different levels.
💡you differentiate the material or instruction, not the students themselves.
