If you don’t have a meal, do you ever notice ...

If you don’t have a meal, do you ever notice yourself starting to get angry very easily? Well, this is often known as being “hangry” or being angry because you are very hungry.

But as it turns out, it’s not just a funny phrase, it is scientifically true! Scientists have found this feeling of anger usually comes from having low glucose（葡萄糖）levels in the bloodstream（血液）. Glucose is put into the body after you eat.

The brain also needs this to work correctly. When the glucose in your body is low, the brain sends hormones（激素）to increase the amount of that. This makes it hard for people to control their emotions. The brain even starts to feel like you are dealing with a life-threatening situation if you don’t get enough glucose. Another problem is that the brain will also use neuropeptide（神经肽）to send a message saying you should eat. And this is the same chemical that manages anger.

Amanda Salis, PhD, University of Sydney, says that we may also be able to thank our ancestors（祖先）for our hanger. Salis says that long ago when there was not much food, people had to be aggressive（富于攻击性的）so that they could get enough food to live.

Even now when most people have enough food to eat, there is still that feeling of needing food.

Would you eat a ready meal from the fridge rather than cook by yourself ? Have you been doing Internet shopping rather than going to the stores?

A study into how lazy British people are has found more than half of the adults are so lazy that they’d catch the lift rather than climb two flights of stairs.

Just over 2,000 people were quizzed by independent researchers in the Britain’s largest health center. The results were very surprising.

About one in six people who were asked said if their control was broken, they would continue watching the same channel rather than get up.

More than one third of those asked said they would not run to catch a bus. Worryingly, of 654 respondents (离婚被告) with children, 64% said they were often too tired to play with them.

We know that it’s no wonder that one in six children in the UK are very fat before they start school.

Dr Sarah, Dauncey, medical director of the center, said, “People need to get fitter, not just for their own health, but for their families, friends and pets, too.”

“If we don’t start to take control of this problem, a whole generation will become too unfit to perform even the most basic tasks.”

And Scotland’s largest city, Glasgow, was shamed as the laziest city in the UK, with 75% asked thinking they do not get enough exercise, followed by Birmingham and Southampton, both with 67%.

So there are some problems for the National Health Service, where fatness-related (相关的) illnesses such as heart disease and cancer have been on an increase for the past 40 years and are costing billions of pounds every year.

1.What does the underlined word “quizzed” mean?

A. questioned　　 B. answered　　 C. listened　　 D. heard

2.Of 654 respondents with children, 64% said _____.

A. they were often too busy to play with their children

B. they were often so tired that they couldn’t play with their children

C. they were often so sad that they didn’t want to play with their children

D. they were often ill and they couldn’t play with their children

3.Which of the following is true according to the passage?

A. All the adults in the UK are very lazy.

B. Half of the children are very fat before they go to school.

C. Pets will be in trouble if their owners don’t keep healthy.

D. All people in Glasgow feel ashamed because they don’t get enough exercise.

4. From the last paragraph, we can learn ______ if they keep lazy.

A. people may have heart disease

B. people can work at home all the time

C. people like shopping online

D. people don’t like climbing the stairs

5. What does the passage mainly talk about ?

A. The health service in the UK.

B. A study of British people’s lifestyles.

When throwing away rubbish, do you know which bin it should go in? Have you ever noticed the differently-colored rubbish bins on the street? Some of you might not be able to answer the questions. However, it's actually quite important to know how to sort your rubbish. Not knowing how to sort rubbish can make it harder to save energy and protect the environment. If you don't sort your rubbish, all of it will be buried (埋) together. It can take up large areas of ground that could have been used for planting trees. Shanghai is the first city to put rubbish-sorting into practice in China.

Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable (可回收的), harmful and dry. "Wet" rubbish is also known as "household" rubbish. It is what people produce every day after they eat or drink. "It is the thing you don't want but pigs can eat", Guangzhou Daily explained. Paper, metal, glass and other things that can be reused are recyclable rubbish.

Harmful rubbish includes things like medicine, batteries and so on. Finally, any rubbish that is not wet, recyclable or harmful will go in the dry rubbish bin. Many other Chinese cities, including Changsha, plan to use this method to sort their rubbish. Now that you know this, perhaps you can do your part in protecting the environment.

1.the bins are different colors because they _______.

A.look more beautiful

B.can help people sort waste

C.are made of different materials.

2.according to the passage, if we sort waste, ______.

A.all of the waste can be recycled.

B.there will be less land for the trees.

C.it’s easy for people to recycle some useful parts of the waste

3.Wet waste may be______.

A.the waste water left by people after washing.

When throwing away rubbish, do you know which dustbin it should go in? Have you ever noticed the differently-colored dustbins on the street?

Some of you might not be able to answer this question. However, it's actually quite important to know how to sort（分类）your waste. Not knowing how to sort waste can make it harder to save energy and protect the environment.

If you don't sort your rubbish, all of it will go to a landfill（垃圾清理场）and be buried together. These landfills can take up large areas of ground that could have been used for planting trees or crops. The electronic waste you throw away, such as batteries, can pollute the soil and groundwater. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

With this in mind, many cities in China have been running waste-sorting campaigns（活动）in recent years. for example, Shanghai announced in 2018 that within three years（2018—2020）, all the people living in Shanghai should sort their rubbish into four groups: wet, recyclable, harmful and dry.

Wet waste is also known as household waste. They are things you don't want but that pigs can eat. Paper, metal, glass and other things that can be reused are recyclable waste.

Many other Chinese cities, including Shenzhen, are using this method to sort their rubbish. Now that you know this, perhaps you can do your part to protect the environment and encourage others to sort their rubbish.

根据短文内容，判断下列句子正（T）、误（F）。

1.If you know how to sort waste, it will help us save energy and protect the environment.

2.Shanghai will achieve the goal of sorting their rubbish into four groups in 2020.

3.The food that we haven't finished eating at home belongs to recyclable waste.

4.Many cities in China are doing waste-sorting work nowadays.

5.The passage mainly tells us how to recycle rubbish.

Have you ever noticed the black and white bars on a book？Do you know what they are used for?

They are bar-codes（条形码）used in most products. If you go to a supermarket，you can see almost every product with a bar-code on it. Bar-codes have information about the product, such as name and production date.It's an easy and convenient way to know about the products. Just scan the bar-code and everything is clear.

The first use of a bar-code in a supermarket checkout system was on a pack of American Wrigley Company chewing gum in 1974.Beyond supermarkets, bar-codes are needed everywhere:for renting cars, for luggage checks on a plane, for parcels(包裹) you send.

With these small codes, life is getting much easier for us.

If you find these bar-code things boring, a bar-code building might be more up your street.
