【题目】Symptoms of Dehydration(脱水)

You’re bad- tempered.

Researchers tested the mood and concentration of 25 women who drank healthy amounts of water one day, and then didn’t over the next two days. When slightly dehydrated, the women reported tiredness, bad temper, headaches, and difficulty focusing. In a separate test, men with mild dehydration also had trouble with mental tasks. 1 Scientists are still trying to figure out why.

You have a bad workout.

2 It impacts how much you can push yourself. Even a 2 to 3 percent fluid loss affects your ability to get a good workout and more than 5 percent dehydration decreases exercise capacity by about 30 percent. A no-brainer way to avoid dehydration and dehydration symptoms is to aim for this much water per day.

3

Driving while dehydrated may be just as dangerous as getting behind the wheel drunk, in terms of how many mistakes you could make on the road. British researchers had participants take two-hour drives [using a simulator (模拟器). When they drank enough water, there were 47 driving errors. 4

You feel dizzy when you stand up too fast.

One of the signs of dehydration is when your blood volume and pressure drops, it can leave you feeling dizzy or faint, or bring on that rush of light-headedness after you quickly get up from sitting or lying down.

The exact treatment for dehydration symptoms depends on age and how severely dehydrated someone is. 5 Most of the time, however, people use some over-the-counter solutions for kids, and adults can drink more water

A. You drive like you’re drunk.

B. Dehydration can be life-threatening.

C. To get rid of dehydration you have to replace lost water.

D. In extreme cases, people might go to the hospital for a treatment.

E. Dehydration reduces blood pressure and makes the heart work harder.

F. But when it came to mood changes, women changed much more than men’s.

G. But when they are short of water, there were more than doubled driving errors to 101.

【题目】 The UK's first fully solar-powered home, which removes the need to ever receive a gas or electricity bill again, has gone on sale, but it will cost you 1.2 million.

The timber-framed home in Great Glen, Leicestershire, contains a number of “zero-carbon feature” including solar electric energy, triple glazing and rainwater storage. It is entirely heated by underground water-filled tubes that are warmed by solar energy from rooftop panels. The house was designed and built by Caplin Homes and covers two acres of land. The design and construction, down to the materials, were used specifically for their low carbon footprint.

The solar panels on the roof of the five-bedroom house are called hybrids because they collect both electrical and thermal energy. Solar walls preheat incoming air, and an Earth Energy Bank (EEB) and heat pump can store heat, and get it back for use when temperatures drop. The south-facing triple-glazed windows are said to also improve the house's energy management during the winter.

All the technologies are controlled by a control system, which monitors the inside and outside temperatures, how much energy is being received by the solar panels, and the heat levels in the EE domestic hot water tank. Due to its low energy design, the Solar House is expected to only require heat from the EEB for about 10 weeks of the year.

For 1.2 million, buyers also get two garages. Estate agent (房地产经纪人) Anthony Fox said the possibility of no utility bills was a big draw for potential owners: the idea is that your bills pretty much disappear and the house is self-sustaining and self-sufficient. That was a big aspect for most of the people who came to have a look around. “We had a lot of interest on the open day. There were some strong considerations to buy there and then. Everyone was very keen to learn how the house worked.” He added.

【题目】 We know that too much of the wrong kind of food can be bad for our health, but for some people having a food allergy, eating certain things can actually be harmful. Now it is seemingly affecting more and more of us.

An allergy is caused by the immune system fighting substances in the environment, known as allergens, that it should see as harmless. 1It means people have to spend their lives following strict dietary restrictions and worrying about the ingredients of everything they consume. We often hear about people having allergies to dairy products and to peanuts. Last year a teenager died after suffering a fatal allergic reaction from eating a baguette containing sesame seeds. 2

Research has found that this problem is particularly affecting children. 3 Dr Alexandra Santos from King’s College London says food allergy now affects about 7 percent of children in the UK, and 9 percent of those in Australia.

4 Dr Santos says, the increase in allergies is not simply the effect of society becoming more aware of them and better at diagnosing them. 5 She adds that possible factors are pollution, dietary changes and less exposure to bacteria, which change how our immune systems respond.

A.So what might be the cause?

B.It seems to be more environmental.

C.Similarly, food allergic reaction is deadly.

D.This led to a call for better food-labeling laws.

E.Besides, more adults are suffering from food allergies.

F.However, food allergies can cause life-threatening reactions.

G.More and more of them are having allergic reactions to certain foodstuffs.
