Article: Alex stared through the cabin window at the darkness. Soon his dad would call him. And he didn't want to go. He wished he hadn't come to the lake for the weekend. "We're ready," Dad said as he came in from the porch. " Grab your rod." Alex turned away from the window and slowly picked up his fishing rod. "Have fun!" Mom said. "Sure," said Alex, trying to make his voice bright. "We should have done this before." Dad said. "Let's catch a big one!" Dad picked up his tackle box, rod, and bait can from the porch. He clicked on the flashlight. They walked down the hill toward the lake in the narrow beam of light. The only thing Alex could see was the circle of weeds and rocks at their feet, lit by the flashlight. Insect voices filled his ears---clicks, hums, buzzes, whines. Hundreds of bugs waited in the darkness to attack. "Ow!" he blurted as he felt a sting on his arm. "Mosquitoes," Dad said. "I have brought some spray to keep them off." When they reached the boat, Alex stumbled as he climbed over the side. "I don't like this much," he said. "It's so dark." Dad squeezed his shoulder. "Don't worry. It's not as dark as you think. After a while your eyes will get used to the night." Suddenly something rushed past Alex's head. He gasped. "What was that?" "Probably a bat," Dad said. How could Dad act as if it were nothing! "Will bats be flying around our heads the whole time?" "This is their time to be out catching insects," Dad explained. "They won't hurt you. They're too busy grabbing dinner." He pushed the boat off the gravel and jumped in. Alex gazed back at the cabin. A square of light from the window glowed in the darkness. Dad rowed to the middle of the lake and stopped. "We'll just let the boat drift. Keep the flashlight in the bottom of the boat. The fish won't bite if they see light flashing around. When we've done baiting our hooks , we'll turn the light off." Leaning down to get closer to the light, Alex tried to thread a worm on his hook, but he couldn't seem to work his fingers right. So... Question: Whom did Alex go fishing with? Yes or no, is the answer "His father"?
No

Article: A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou,Hunan Province on May 17.Nine people were killed and 16 injured. Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the colorchanging material is a type of molecule .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. If the bright light keeps the red color from appearing,the material's warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab. Question: What can we infer from the passage? Yes or no, is the answer "There is a long way to go before the material can be applied."?
(Answer)
No

Ques:Article: Do you always forget where you placed your keys or your purse? What was the name of the movie you saw last week? The major cause of your forgetfulness may be linked to what you store in your body, not in your short-term memory bank. Tests continue to show that people with enough Vitamin B-2 do well in memory exams. The "B" could stand for "brain", if you're one of many with limited instant recall. And the number one source of that vitamin is sunflower seeds. Even when you're sleeping or relaxing, your brain is still at work. Although it makes up just two percent of your total body weight, it uses up to 30 % of the calories you take in each day. For it to work properly, it must be fed. Even if you're not a breakfast eater, that meal is the best way to prepare your brain for the day. A quick and easy English _ with peanut and butter in it, a glass of milk, and an orange, might be what your brain may be asking you the first thing in the morning when you feel your head is in a fog. Having sunflower seeds and fruit between meals adds more muscle to that hungry, demanding organ. Vitamin B-1 also helps the memory, and that is found in eggs, meats and nuts. In Chinese culture, walnuts are known as the fruit for a long life because it is believed that they feed both the kidneys and the brain. And according to Chinese culture, if you keep those two important organs in good working order, you'll live longer. However forgetful you are, just keep in mind the letter "B", which will help you to "bear in mind almost everything" even on those days when life's challenges are sending you in a billion directions. Question: In the passage, Chinese culture is mentioned to _ . Yes or no, is the answer "show the importance of vitamin B-1"?

Ans:
No
