1 . Mosquito bites are unavoidable in summer—or is that so? Scientists recently found that mosquitoes are more attracted to some colors than others, which could possibly prove useful to those trying to avoid the annoying bites.

The study found that after a common type of mosquitoes smelled CO₂ the gas humans breathe out—they decided to land on some colored dots (色点) but ignored others.

“Imagine you’re on a sidewalk and you smell toasty,” the lead researcher said in a press release announcing the study’s findings. “That’s probably a sign that there’s a bakery nearby and you might start looking around for it. Here, we started to learn what visual elements that mosquitoes are looking for after smelling their own version of a bakery.”

The research team put different colored dots at the bottom of a box and sprayed (喷洒) them with CO₂. They found that mosquitoes were drawn most to red, orange and black. They also found that mosquitoes ignored green, blue and white. When a researcher reached his hand into the box wearing a green glove, mosquitoes ignored it, even when it was sprayed with CO₂.

Unfortunately, avoiding mosquitoes isn’t as easy as choosing the right color of clothes. Human skin delivers a vivid red-orange “signal” to mosquitoes, the researchers said, making it hard to hide completely

“We previously discovered there are three major hints that attract mosquitoes: your breath, your sweat and the temperature of your skin,” the lead researcher said. “Now we have found a fourth hint: the color red, which can not only be found on your clothes, but is also found in everyone’s skin. The shade of your skin doesn’t matter. We are all giving off a strong red feature.”

While the research found that the mosquitoes appeared to prefer certain colors, it did not measure whether wearing colors like green or blue would help keep away from the mosquitoes. The researchers hope that their findings can help find other methods to drive back the biting insects.

2 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Aunt Evie had a dollhouse. It had many toys there. Every Friday afternoon, I went to Aunt Evie’s home with my parents. The adults would sit around a table in the dining room, eating pie and talking, while I played in the dollhouse for hours.

Sometimes I would pick up these lovely toys and place them in different positions. It was really fun. One time I asked Aunt Evie where she got the toys so that I could buy some, too. To my disappointment, Aunt Evie said that most of them were specially handmade gifts from her friends and couldn’t be bought anywhere. One such toy was a little bear, which was my favorite. It was so beautiful that I wanted to own it badly. “If I take it, Aunt Evie may not notice it. ” I said to myself.

Therefore, on a Friday afternoon, I attempted to take the little bear away from Aunt Evie’s dollhouse. I had to wait until nobody was watching me, ‘and it took me hours to get the courage to put the little bear in my pocket. Once I got the little bear, I couldn’t wait to go home. I had to hide it somewhere at home, so that no one would know I took it. That night after I went home with my parents, I couldn’t go to sleep. “What a bad person I am! I stole something from my loved Aunt Evie.” I thought. When I woke up the next morning, I felt awful, but I couldn’t tell my parents, let alone return the little bear to Aunt Evie. I was embarrassed about my behavior. At some point, I started to hate the little bear and myself. And I knew if I didn’t do something, I wouldn’t get away from those bad feelings.

3 . Mountains are great places to spend your free time, but they can be dangerous if you’re not prepared. Imagine you went hiking with your friends or family and got lost while taking pictures of plants and animals. What if you couldn’t find your way back and had to wait until someone came and saved you?     1    

Fire is important because mountains get cold at night, even in the summer. Fire also keeps dangerous animals away and can let people know where you are.     2     If you don’t have either of these, you can hit a rock against a piece of steel to make a spark(火花)and start a fire. Just make sure that the fire doesn’t spread!

    3     Humans can’t live without water. If your drinking water runs out, you’ll need to find clean water as soon as possible. It’s best to look for running water, such as a stream or river. If you can’t find any, try digging a deep hole to find water underground. Or, if you have any empty containers(容器), you can use them to collect rainwater.

    4     A cave can be a good shelter. If you can’t find one, find a dry area, build a frame(支架)with branches, and cover it with a blanket. If you don’t have a blanket, cover your body with a pile of leaves instead.     5    

Remember, you should never go into the mountains without the right skills and equipment. But if you’re prepared, you’ll have a safe and enjoyable experience.

A．Finally, you will need some kind of shelter.

B．Another thing you’ll need is clean drinking water.

C．To survive, you’d need three things: fire, water and shelter.

D．You can survive for hours without shelter in ice conditions.

E．This will keep you dry on the rainiest nights and block the wind.

F．It’s important to keep your home warm to avoid health problems.

G．Therefore, you should always carry a lighter or a box of matches with you.

10 . How to Set Up an Art Exhibition

When you’ re displaying your own work, it’ s a real challenge to bring together so many different elements in a meaningful way,     1    . You should do something as follows:

Choose a specific theme

A good art exhibition should be characterized by a specific theme that ties the different pieces together and makes them feel like part of a larger whole. Think carefully about the message you want your exhibition to convey. It could be an image or phenomenon, a feeling or a certain visual technique.     2    .

Select your most impressive works

Pick out a few of your best or most impressive pieces to put on display. If the exhibition is meant to highlight your own work, you’ll need to have 30 individual pieces.     3    . Plan on exhibiting more pieces if the work you do tends to be on a large scale.

    4    

Do some research into other artists in your area and see whether they would be interested in your exhibition. Holding an exhibition with other artists will also allow you to reduce some cost. Be sure to give other artists proper credit for their works.

Involve in different art forms

    5    . Feel free to more works from photographers, sculptors and other artists. A wide-ranging selection will contribute to a good atmosphere. You might also consider inviting poets or musicians to perform at the event.

A．That’s why it’s essential to have a plan

B．Contact local artists for your exhibition

C．They must be representative of your works

D．It is good for you to learn different types of art

E．The more specific your theme is, the better it will be

F．Your exhibition doesn’t have to only feature paintings

G．You might consider interviewing some local celebrities
