Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic（遗传的）structure with the simple worm.

But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome（染色体组）.

To help them do this, they turned to the worm. The nematode（线虫类的）worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.

What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.

Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.

There are a lot of products out there that make your life easier. Some, however, are a little sillier than others — so much that they seem like joke products. Here are a few products that sound crazy, but actually rule.

Sleep Phones

It’s hard to imagine something sillier than a music-playing headband you wear while you sleep, but they exist — and are quite popular. Sleep Phones won’t give you the highest quality sound in the world, but if you prefer to fall asleep to music, they’re far more comfortable than normal headphones. While they’re a bit expensive, they might be perfect for you. There’s also a wireless version (版本) if you prefer.

Onion Goggles

If cutting onion brings on the waterworks no matter what you try, it’s time for desperate measures. We tested a bunch of methods for avoiding onion tears, and found the best solutions came down to cutting the onion under a vent (通风孔), or wearing these stylish and awesome goggles.

Lock Laces

There’re some great ways to tie your shoes better, but if you long for the laceless shoes of your childhood days, Lock Laces are a pretty good choice. They’re basically elastic (有弹性的) laces that remove the need to tie your shoes. Sure, people will make fun of you, but you can make fun of them after they trip over their own untied laces. Or you can make your own slip-on shoes with elastic tubing.

2D-Glasses

Hate 3D-movies, but have to go to one? The difference between 2D-glasses and 3D-glasses lies in their lenses (镜片). Each lens of 2D-glasses blocks the same picture, so each eye gets the same picture, while each lens of 3D-glasses blocks a different picture, so each eye gets a different picture which the brain interprets as 3D. Now you have a pair of glasses that can save you from the headache caused by wearing 3D-glasses which are popular in our movie theaters. You can buy them or make a pair for yourself.

1.What do we know about Sleep Phones?

A. There are two versions.

B. They’re comfortable but unhealthy.

C. They give you the best quality sound.

D. They’re cheaper than other headphones.

2.The underlined part “brings on the waterworks” in the text probably means _____.

A. makes your eyes water

B. makes your fingers hurt

C. destroys your water pipes

D. adds to your washing work

3.What is the advantage of Lock Laces?

A. They are strong and lasting.

B. They help you walk comfortably.

C. They are stylish and eco-friendly.

D. They save you from tying your shoes.

4.Compared with 3D-glasses, 2D-glasses _____.

When the accident was happened, I was standing near a bus stop. There I saw an old lady waiting a bus with her umbrella. The bus soon arrived. There were too many passengers hurried to get on it that the old lady couldn’t get on. A driver closed the door without looking careful and drove away. Unluckily, the old lady’s umbrella was caught by the door. He shouted to the driver but he didn’t hear. The bus pulled her along the road. Finally, she fall to the ground. Several minutes late, the ambulance came and took her to hospital. I thought it was the driver should be responsible for the accident.

Your house may have an effect on your figure. experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they’re in poorly lit places – and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it’s time to repaint, go blue.

Don’t forget the clock – or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

1.The text is especially helpful for those who care about ____.

A.their home comforts B.their body shape

C.house buying D.healthy diets

2.A home environment in blue can help people ____.

A.digest food better B.reduce food intake

C.burn more calories D.regain their appetites

3.What are people advised to do at mealtimes?
