Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition（眼睛识别 program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology（技术） will take the place of all other ways of finding out who people are.
However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct at present. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.

Traffic lights are red， yellow and green． They are very important signals（信号）． Traffic lights are usually placed at busy street corners to help control traffic． Sometimes， they are on streets near schools and shops，too． Most young children are taught what each of the colored lights means， so everybody can stay safe．
The first traffic signals were used for trains． The signals were put alongside railway tracks（轨道）．The color red was used to mean "stop" because it warned people of danger． A red light was also the easiest color to see from a distance． Train drivers could see the red "stop" light ahead and had enough time to slow down and stop their trains． A green light was used to mean "take care" and a white light meant "go"．
However， there were many dangerous accidents on the train tracks． Some train drivers thought a star shining in the night sky was a white light that meant"go"． So the signals were swapped． The "go" light was changed to green and the "take care" light was changed to white．
During these times， people travelled by train or in carts pulled by horses．Years later，when cars were built， people began to drive them because they could travel much faster than horses． However， the road rules for drivers were not very clear and many people were hurt crossing the roads．Yellow warning signs had to be placed beside the roads to remind drivers to take care and allow people to cross safely．
Today， towns and cities all over the world have traffic lights． Red and green lights match the signals used on the railways． Yellow lights are easy to see， so they are used to warn drivers that they should slow down and prepare to stop．
（1）Why was the color red used to mean"stop"？
A． It reminded people of traffic rules．

B． b﹣c﹣a
C． a﹣c﹣b
D． b﹣a﹣c
（4）What is the passage mainly about？

New uses for old clothing Nowadays， we're more wasteful than ever﹣buying， using and throwing things away without thinking about the costs． We need to start living more responsibly﹣ but how？ One answer is to upcycle （再生利用）． If you're like me，you might already make soil for gardening from food waste and use empty paper boxes as storage space． Did you know you can apply （应用） the same way to old clothing？ You just need imagination! I started upcycling clothing． Making new things out of old clothes is the best way to mix my talent and my interest． Do you upcycle？ If so， what new things have you made？ If not， why not give it a try？ |

Reply Terry B Posted at 9：08 a． m． on 11th February 2018 Why don't you give your old clothes to people in need？ I even give away the most expensive things I don't wear anymore． So I can help the environment while giving something useful to people in need．
Reply Gina Posted at 9：28 a． m． on 1lth February 2018 earl Good point! I'm talking about only the oldest clothing in your room ﹣ the clothes that are too old to be worn by others． The same idea goes for food waste at restaurants and supermarkets． Before upcycling food that can still be eaten， for example， using it to make soil， we should give it to those in need． |

It was a summer day． An old man walked on a hill cheerfully．
He wiped the swear off his face with his left hand and kept singing songs．
Suddenly he heard someone talking to him．
"Hello． sir．"
The old man turned around but saw no one．
"I'm here．"
The voice came from beside the old man's feet， He looked down and saw a beautiful flower．
"Sir， can I ask you a question？" asked the flower．
"Of course， my child． What do you want to know？" said the old man．
The flower kept silent for a second and then said："Why are you so happy？ You don't seem to have many days left to live．"
The flower didn't wait for the old man to answer． She just kept saying， "My days have passed and I'm going to die very soon． That makes me so sad．" At this time， she began to cry．
The old man smiled．
"Yes， I don't have many days left． But， so what？"
"Why ruin（破坏） such a lovely day for something that hasn't happened？"
"What's gone is gone． What's to come is to come． You can't change them． but you can decide to enjoy this very moment that you truly have．
He didn't wait for the flower to answer．He just walked away，continuing the song he had been singing．
Slowly the flower stopped crying． As the wind was blowing softly． she swung happily．

（2）Where did the voice come form？

We touch our faces all the time， and it had never seemed to be a big problem ﹣ until COVID 19 arrived．Touching our faces ﹣ the "T﹣zone' 'of our eye， nose and mouth ﹣ can mean giving ourselves this virus．
This is why some organizations have suggested that we should avoid touching our faces．William Sawyer， from Henry the Hand． told The Washington Post， "Just stop this simple behavior，and that would be better than any vaccine （疫苗）lever created，"
However， stopping this "simple" behavior might he harder than you think because we are used to it．
Some face﹣touching is an automatic reaction： like when there is an itch （痒） on your nose，you'll touch it again and again without thinking． A 2014 study found that touching your face also helps you to have less stress．For example． it's possible for you to do it when you feel embarrassed．According to Dacher Kelmer， a psychologist an the University of Califormia Berkeley， Us． this action may also have a social use： When you are taking to someone， for example， touching your face means you want to talk about another thing．
Besides， it's very hard to change this face touching "because you don't even kn6w you're doing it"，said Sawyer．
But you're not alone． In a 2015 study． it was found that a group of medical students touched their faces about 23 times an hour ﹣ with 44 percent of the touches in the T﹣zones" ， That was very surprising because medical students should know better．
Since it's so hard to shake the habit， maybe the easiest way is to wash our hands more often．This way， we can be sure that our hands are safe from COVID﹣19．
（1）The "T﹣zone" is formed from ．
A． Our eyes
B． our nose and mouth
C． our eyes， nose and mouth
（2）In the second paragraph， Sawyer thinks that ．
A． face﹣touching is simple and helpful
B． we should avoid touching our faces
C． face﹣touching may be better than vaccine
（3）Dacher Kelmer believes that ．
A． face touching may increase stress
B． face﹣ touching may have a social use
C． face﹣touching may cause an itch on your face
（4）The last paragraph tells us to ．
A．wash our hands more often
B． stop the habit of touching our faces
C． ask medical students not to touch their faces
（5）What is the main idea of the passage？
A． face﹣touching may give us COVID﹣ 19．
B． Face﹣touching may be very useful for us．
C． Stopping face touching might be harder than we think．
