true, or correct a representation is.

Arrangement (N-page 34) : refers to the

way in which lines, images, or object are

placed in relation to one another

Sự sắp xếp

Decode (V-page 36): to decode a

message is to convert it from a code or

signal into a format that others can read.

Giải mã

Infrared (A – page 37) : if an electromagnetic

light is infrared, it has a wavelength shorter than

visible red light and longer than microwave light

These low power, low cost lights are grease, dirt,

and opaque coverings.

offers long scanning range and fast

capabilities It is usually used at fixed

scanning terminals.

Interpret (V- page 37) : is to explain or translate

information

durable, low-powered laser These are

usually used in handheld scanning units.

Product tracking (NP – page 38) : is a system

that uses electronic identification to monitor products as

they arrive and move through the manufacturing and

shipping processes.

Hệ thống Theo dõi Hàng hóa

Reflect (V - page 39) : to reflect light is to

bend it back from the surface of an object.

Phản chiếu

Unique (A – page 40) : if a code is unique, no

other code will be exactly the same.

Duy nhất

Update (V – page 40) : is to supply the

most recent information or changes.

Wireless (A – page 40) : If a signal is wireless,

it is transmitted without the use of wires.

Explaining warehouse management systems (WMS) evolved much like many other software solution The

most significant changes have been brought about by technological improvements These have improved accuracy

and efficiency.

A modern WMS is comprised of two main elements First, there must be a system in place to identify products

as they enter the system Second, a computer program dedicated to product tracking must be installed.

In a warehouse, this is often a bar code system Each bar code is a unique combination of lines The

arrangement of the lines of varying widths relays coded product information A scanner is used to read and

decode bar codes Scanners use light to read bar codes This light is reflected back from the spaces between the

lines.

Scanner technology uses many methods including:

 Infrared

 Laser diode

 Helium neon laser

The information is sent to computers This is often carried out by wireless transmission.

The computer system is an equally important element of the WMS It contains software that can interpret the

decoded information The system is continuously updated as materials move through various tracking points.

A WMS is a valuable addition to any manufacturing operation.

READING

Read the journal article Then, mark the following statements as true (T) or false (F).

1 Warehouse management systems improve product

tracking accuracy (Paragraph 2)

2 The lines on a bar code reflect light (Paragraph 3)

3 A laser diode is a type of scanner

T

T F

(Paragraph 4)

5 Listen and read the journal article again What are the two

elements that make up the WMS?

A modern WMS is comprised of two main elements A system for

reading coded tracking devices, such as bar codes, and a software

program designed to track materials as they move through the

system.

VOCABULARY

1. The woman used to work for a different manufacturing company.

2 The new WMS will only use infrared scanners.

3 Infrared scanners can read through grease.

true (T) or false(F).

+ Active : Tom broke the chair yesterday

+ Passive : The chair was broken by Tom yesterday

S + BE + PAST PATICIPLE

2 Usage:

Passive is used when we want to emphasize action in

sentence, the cause of action is not important or whoever

thing.

3 Notes:

It’s your duty to + V inf

 Passive: You’re supposed to + Vinf

@For instance:

It’s your duty to make tea today

>> You are supposed to make tea today.

It's impossible to+Vinf

 Passive: S + can't + be + P2

@For instance:

It's impossible to solve this problem.

>> This problem can't be solved.

 It's necessary to + Vinf

 Passive: S + should/ must + be +P2

@ For example:

It's necessary for you to type this letter

>> This letter should/ must be typed by you.

4 Passive with have/get:(Thanks to who do)

Structure:

Active: Have + sb + V  Passive: Have + sth + P2

Active: Get + sb + to V  Passive: Get + sth + P2

@For example :

I have my father repair my bike >> I have my bike repaired by my father.

I get my father to wash my car >> I get my car washed by my father.

My parents never let me do anything by myself.

→ My parents never let anything be done by myself or I'm never allowed to do anything by

myself by my parents.

6.Passive Structure From Author " IT".

Active: It + be + adj + for sb + to do st

Passive: It + be + adj + for sth + to be done.
