We all have at least a few bad habits. But when it comes to sleep, bad habits may be preventing you from getting the rest you need. Below are some common bad habits that can affect your quality of sleep.

Exercising too close to bedtime: 1.. But if you exercise too close to bedtime, it can excite you and keep you from falling asleep. If you’re hitting the gym in the evening, make sure it’s three or four hours before you plan to sleep.

2.: Screen light tricks your body into thinking it’s daytime. It causes the hormone (激素) which helps regulate sleep to stop working. Consider limiting screen time to an hour or two before bed.

Late-night eating: It can affect sleep, for example, lying down shortly after eating a heavy meal can cause heartburn. 3..

Working right up until bedtime: 4., if you’re thinking about work. Instead of working before bed, do something relaxing like listening to music or taking a warm bath.

Getting up late on the weekends: 5., though it might feel good. Consistency is key to developing sleep patterns that improve the quality of your sleep. So, consider sticking to the same sleep schedule even on the weekends.

A.Extra sleep may break your body’s natural habit

B.Have a light snack if you’re hungry at bedtime

C.Enough sleep plays a key role in keeping fit

D.Doing sports is great for overall health

E.It’s hard for your mind to settle down

F.Leaving your phone beside you

G.Watching your phone in bed

The behaviour of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放)by 80 percent by 2050, part of which will be achieved by all new homes being zero carbon by 2016. But this report shows that sustainable building design on its own—though extremely important—is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，which instead focus on architectural and technological developments.

“Technology is going to assist but it is not going to do everything，”explains Katy Janda, a UKERC senior researcher，“consumption patterns of building users can defeat the most careful design.” In other words，old habits die hard, even in the best designed eco home.

Another part of the problem is information. Households and bill payers don't have the knowledge they need to change their energy use habits. Without specific information，it's hard to estimate the costs and benefits of making different choices. Feedback (反馈) facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

Social science research has added a further dimension (方面)，suggesting that individuals' behaviour in the home can be personal and cannot be predicted—whether people throw open their windows rather than turn down the thermostat (恒温器) , for example.

Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.

1.As to energy use, the new research from UKERC stresses the importance of ________.

C. sustainable building design

D. the reduction of carbon emissions

2.The underlined word “which” in Paragraph 2 refers to“________”．

A. the ways 　　 B. their homes

3.What are Katy Janda's words mainly about?

A. The importance of changing building users' habits.

B. The necessity of making a careful building design.

C. The variety of consumption patterns of building users.

D. The role of technology in improving energy efficiency.

高二英语阅读理解简单题查看答案及解析

Sometimes it can be easy to become too satisfied when it comes to living sustainably. We may all have recycling bins in our kitchens, but here are some ways you can live more sustainably.

1. Put an end to plastic water bottles and one-off coffee cups

The only way this is going to work is that if you have reusable options you really love, invest in a great water bottle. This is an advance payment, but it will save you money in the long run. A 750ml bottle of Evian costs 90p in Tesco, meaning if you buy one every two days you could save £10 within three weeks by filling up a reusable bottle at home.

2. _______________________________________

The high street is problematic on so many different levels. Not only are you buying items with questionable supply chains, but the carbon footprint of each product is shocking as well. Online shopping is even worse, with overpackaging for each item and the emissions from delivery trucks. The answer is to stick to reach-me-down or previously owned items as much as possible. Not only will this save you money, but there’s also a sense of satisfaction in finding a hidden treasure from the flea market where you find outstanding bargains or something used, which you simply can't get from shopping in Wal-Mart or on Amazon.

3. Think hard about your transportation

Even if your car is supposedly a low-emissions model, it’s still going to be a huge contribution to your carbon footprint. There are times when getting in a car can’t be avoided, but if you can substitute just one flight a year with a train, one car journey a week with a bus. and one bus a month with a bike ride, you’ll find that making more mindful transport decisions can easily make your day-to-day life more environmentally friendly with little effort.

4. Try to buy local, seasonal produce

You may think buying strawberries in December or courgettes in spring is no big deal, but the chemicals and fuel used to artificially copy the right environment for them to grow create harmful gas emissions. Similarly, the environmental impact of transporting produce from another country is huge. Buying from local farmers also means you can often ignore the huge amounts of packaging the supermarkets use.

1.According to the passage, if we want to lower our carbon footprint, we’d better ________.

A. purchase a 75ml bottle of Evian in Tesco every other day

B. never do some shopping in Wal-Mart or on Amazon

C. buy strawberries in December or courgettes in spring

D. take transport with a low-emissions model if possible

2.Which of the following is most suitable to fill in the blank?

A. Avoid too much traffic on the high street.

B. Buy items without questionable supply chains.

C. Buy second-hand products as much as possible.

D. Avoid buying items with excessive packaging.

We’ve all experienced that feeling that comes when your phone makes a sound to tell you that its battery level is low. It often comes at the worst times – when you’re out on a trip and don’t have a charger, or when you’re expecting an important phone call.

Indeed, this feeling is so common that South Korean electronics manufacturer LG has given it a name: low battery anxiety.

According to a survey of 2,000 US adults conducted by the company last year, 90 percent of respondents said that they panic if their battery level reaches 20 percent or lower.

And last month, UK telecommunications service provider 02 found that around 15.5 million Britons live in “constant fear” of their mobile phones running out of power, according to a survey by the company.

“The problem is not about being unable to make calls, but is rooted in the fact that smartphones are now where we store digital memories,” noted the Daily Mail.

However, battery worries don’t just affect smartphone lovers. Many owners of electric vehicles also suffer from so-called “range anxiety”. This refers to the concern that the vehicle may not make it to its destination before the power runs out.

Meanwhile, it isn’t just low power that people worry about. A study carried out by South Korea’s Sungkyunkwan University and China’s City University of Hong Kong found that many of us also worry about not having constant access to our phone.

This condition is known as nomophobia, short for “no mobile phone phobia（恐惧症）”. Symptoms include feeling uncomfortable when access to one’s phone isn’t possible, being unable to turn off your phone, and constantly topping up the battery to make sure it never dies.

So, why do so many people treat their smartphone with such importance? The underlying reason may be that they keep us connected to the people around us, and if we’re unable to use our phone, we feel like we’re cut off from our social life.

With products with bigger batteries being released all the time though - such as Xiaomi’s Mi Max smartphone range or Tesla’s Model S cars – battery anxiety may hopefully soon be a thing of the past.

1.The major reason for people’s “low battery anxiety” lies in ________.

A. They cannot afford to miss important calls.

B. They may lose contact with their friends when they’re out on a trip.

C. The charger is not available when needed.

D. They have no access to the digital memories stored in the phone.

2.The following conditions indicate that you are likely to experience “nomophobia” EXCEPT that ________.

A. you attach great importance to connecting with the outside world

B. you find yourself searching for your phone when it is not at hand

C. you constantly charge your phone to almost full

D. you always keep your phone on

3.What can we learn from the passage?

A. All of the respondents do not panic when their battery level is lower than 20%.

B. People who experience “range anxiety” worry about the quality of their car.

C. People value their phone because they want to participate in more social activities.

D. All these problems will be solved if products with bigger batteries are released.

4.What’s the writer’s attitude towards the solution to low battery anxiety?

A. Unconcerned.　　 B. Skeptical.

C. Positive.　　 D. Disapproving.
