The Eurotunnel is a tunnel(隧道) which crosses the Channel under the sea, linking France and the UK. It is about 50.5 km long and 38km lies under the seabed. There are trains which carry passengers and cars, and others which carry carriages or other heavier vehicles(车辆), as well as goods.

The construction of the tunnel started in 1986, with a cost of almost 10 billion pounds. It was opened in 1994 but was not financially successful until 2007, because of the high interest rates (利率) the company had to pay the banks, as well as low earnings from passengers and goods.

The Eurotunnel is a very convenient way of traveling between the two countries as the journey is quick (less than one hour), cheap, and comfortable. You can go with your car, motorbike or bike. The tunnel operates every day, round the clock. At the busiest times there are up to three shuttle departures (班次) per hour. There are facilities(设施)for disabled passengers and for babies at the two terminals (终点站).

The Eurotunnel, also commonly known as the Channel Tunnel, Eurochannel and Eurochunnel is environmentally friendly. It perfects its sources of energy through its use of renewable energy with the result that, by 2008, it had reduced its greenhouse gas emissions(排量) by 45%. In addition, 50% of the waste produced is recycled.

The future of the Eurotunnel seems promising, although some people who have the fear of enclosed(与外界隔绝的)spaces will never use this type of transportation. There have been some problems with snow storms like the one in the winter of the 2009 which have made the services stop for a period of time, leaving passengers in the tunnel for more than 15 hours without light, heating, food or drink, inside an unmoving train under the sea. Some of the passengers reacted very badly and decided not to use this means of transport again.

With all of the wonderful things life brings us, it also brings us stress. It is for this reason that I am an active supporter of mental health days.

Although it’s never good to ignore(忽视) responsibilities, sometimes it is good to unplug(拔除) from the world for a day. We eat healthy and stay active to keep us from getting sick, but sometimes we forget to care for our minds. Our minds and bodies are connected, and when only one is being cared for, the other may be suffering. It is important to try to combine self care with our lives and spend time on activities we enjoy. This helps relieve stress on a daily day.

So, what do you do on a mental health day? The answer is anything you want. Growing up, my brother and I were allowed a few mental health days a year. We would stay home from school and relax. For him, it was playing games on the computer, while my days were spent reading or watching TV. My mental health days now include picking things up around my apartment, cooking a tasty meal, and then reading for a few hours. I completely shut myself off from work or school. To me, this is relaxing. Organize the clutter(凌乱的东西) that piles up during the week, cook the meals I don’t have time to cook, and read the books that I’ve bought but don’t have time to read.

A mental health day is great, but only if it’s supplemented(增补) with self care through the week. From my experience, if self care is not regularly provided in your week, taking a mental health day is just going to stress you out even more. But when it’s needed, try hard to recognize that and take care of yourself. It will help keep you happy and healthy. A mental health day is not a day to avoid life, it is a day to recoup(恢复).

Babies should be given peanut early - some at four months old - in order to reduce the risk of allergy(过敏), according to new US guidance.

Studies have shown the risk of peanut allergy can be cut by more than 80% by early exposure(接触). The National Institute of Allergy and Infectious Diseases said the new guidance was "an important step forward".

However, young children should not eat whole peanuts, because of the risk of choking.

Allergy levels are soaring in the US and have more than quadrupled since 2008. It is a pattern replicated across much of the Western world as well as parts of Asia and Africa. Parents are often wary about introducing peanut and in the past have been advised to wait until the child is three years old.

According to the new guidelines, children with other allergies or severe eczema should start on peanut-containing foods at between four and six months old, with medical supervision(监管). Babies with mild eczema should have peanut-containing food at about six months old. Those with no eczema or allergies can have peanut-containing food freely introduced.

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, said: "We expect that widespread implementation of these guidelines by healthcare providers will prevent the development of peanut allergy in many susceptible children and ultimately reduce the prevalence of peanut allergy in the United States."

Michael Walker, a member of the European Academy of Allergy and Clinical Immunology, said: "The guidelines are based on sound medical research carried out in the UK. UK parents should consult their GP, bringing attention to the guidelines if necessary, before attempting peanut allergy prevention in their infant themselves."

Professor Alan Boobis, from Imperial College London, said: "The previous(之前的) view that delaying(延迟) the introduction of allergenic foods decreases the risk of food allergy is incorrect and... if anything, the exclusion(除去) or delayed introduction of specific allergenic foods may increase the risk of allergy to the same foods, including peanut."

1.The new US guidance may agree that _________ .

A. children can have peanut-containing food freely

B. parents can feed kids peanut until they are three

C. early exposure to peanut can reduce peanut allergy

D. young children should not eat whole peanut to avoid allergy

2.The underlined word in Paragraph 6 means __________ .

A. easily influenced

B. seriously disabled

C. mentally healthy

D. terribly tired

3.What can we learn from Michael Walker?

A. The use of the guidelines should be limited in the UK.

B. The guidelines are scientific and thus can be trusted.

C. Parents should do peanut allergy prevention themselves.

D. Many doctors in the UK don’t agree with the guidelines.

4.What might be the author’s purpose of writing this passage?

A. To warm parents of the possible danger peanut may bring.

B. To recommend delaying the introduction of allergenic foods.

C. To compare two different scientific research on peanut allergy.

D. To introduce a new way of reducing the risk of peanut allergy.

In 1905, as part of his Special Theory of Relativity, Albert Einstein published the point that a large amount of energy could be released from a small amount of matter. This was expressed by equation E = me 2(energy = mass times the speed of light squared). But bombs were not what Einstein had in mind when he published this equation.

In 1929, he publicly declared that if a war broke out he would “refused to do war service, direct or indirect…” His position would change in 1933, as the result of Adolf Hitler’s coming into power in Germany.

Einstein’s greatest role in the invention of the atomic bomb was signing a letter to President Franklin Roosevelt urging that the bomb be built because some physicists feared that Germany might be working on an atomic bomb. Among those concerned were physicists Leo Szilard and Eugene Wigner. But Szilard and Wigner had no influence with those in power. So in July 1939 they explained the problem to someone who did: Albert Einstein. After talking with Einstein, in August 1939 Szilard wrote a letter to President Roosevelt with Einstein’s signature on it, which was delivered to Roosevelt in October 1939.

Germany has invaded Poland the previous month; the time was ripe for action. That October research of a-bomb began but proceeded slowly because the invention of the atomic bomb seemed distant and unlikely. In April 1940 an Einstein letter, ghost-written by Szilard, pressed the researchers on the need for “greater speed”.

As the realization of nuclear weapons grew near, Einstein looked beyond the current war to future problems that such weapons could bring. He wrote to his friend about his fear about the future use of the a-bomb.

The atomic bombings of Japan occurred three months after Germany gave in.

In November 1954, five months before his death, Einstein summarized his feelings about his role in the creation of the atomic bomb: “I made one great mistake in my life… when I signed a letter to President Roosevelt recommending that atom bombs be made; but there was some justification---- the danger that the Germans would make them”.

1.What can we learn about Szilard and Wigner?

A. They were not as influential as Einstein.

B. They were responsible for the invention of nuclear weapons

C. They had cheated their friend Albert Einstein.

D. They had an intention to destroy the world.

2.We can conclude that Einstein ___________.

A. was important in the development of atomic bomb

B. was not involved in the invention of atomic bomb

C. directly participated in the invention of the atomic bomb

D. helped with the invention of atomic bomb

3.The best title for the passage would be __________.

A. A Story of Albert Einstein

B. Albert Einstein and the Atomic Bomb

C. It was Unfair for Einstein

D. How the Atomic Bomb was Invented

This day marks the rising of a new food startup, the first company to be financed entirely by the crowd, and of it every business thus relies on thousands of customers to grow. Lisa, 25, its main founder and CEO, believes it will be a path that will become increasingly popular, and ultimately will produce more thriving(繁荣的)businesses from the scratch.

“In the food industry, no venture capital (VC, 风险投资) will even look at you until you’ve hit a million in sales. As a fresh hand in business, unless you’re independently wealthy, you will likely need to raise some money before then,” Lisa complained. So few businesses approached VC firms at the beginning. It was no exception with her. Thus, she turned to a new financing tool at hand, crowdfunding, to raise money from the crowd who’d like to take a bet on her company.

But for a company, it didn’t make sense to seek investments when all they had was an idea and a few months of consumer testing data. The food market is extremely competitive. No investor would put money behind a totally unproven new super food product founded by a bunch of twenty-somethings. “But we had a story. And crowds love stories.” Lisa said delightedly. So she put together an online crowdfunding campaign, explaining how she began working with this amazingly nutritious plant in the Peace Corps and then started selling it in the U.S. to support the poor in the West Africa.

On the online platform where they were to raise the money, a friend convinced them to change their goal from $20,000 to $50,000. Lisa stayed up all night worrying they wouldn’t hit it. But they reached $24,000 in 24 hours and ended their funding with $53,000. Seeing the number, Lisa said, “Thank you! To my crowd and for your belief!”

1.Why couldn’t Lisa get investments in a traditional way?

A. She lacked confidence in business.

B. Her food company was in poor condition.

C. VC demanded too much in choosing partners.

D. Consumers were not satisfied with her new products.

2.According to the passage, crowdfunding ________.

A. ensures the investors a good return

B. aims to help badly managed companies

C. attracts more people to become investors

D. helps startups deal with money shortages

3.The underlined word “twenty-somethings” refers to ________.

A. twenty impractical ideas B. young people over twenty

C. twenty inexperienced partners D. a company with twenty branches

4.Which of the following best explains Lisa’s success?

A. Great minds think alike. B. Honesty is the best policy.

C. Many hands make light work. D. A friend in need is a friend indeed.
