For a few months twice a year, the waters off California are home to gray whales moving north or south between the coast of Mexico and the Bering Sea. This year, however, it seems that fewer whales are surviving the journey north. So far this year, a total of 30 dead gray whales have washed up on the West Coast: Eight in Washington, one in Oregon and 21 in California. Those numbers are unusually high.
In Northern California, three out of four of the dead whales that have been examined so far appear to have died of starvation and the fourth was killed by a ship strike, said Barbie Halaska, a research assistant at The Marine (海洋的) Mammal Center (TMMC), a nonprofit organization that rescues and rehabilitates (使康复) marine mammals in California. Halaska and her colleagues examined the four whales—three young whales and one adult male — and planned to examine the remaining dead whales in the region in the next couple of days.
Gray whales were once severely threatened by whalers. Only around 2,000 of them lived in the ocean in 1946, so an international agreement to stop gray whale hunting was signed in order to help the population recover. Gray whales were removed from the endangered species list in 1994 when the population reached 23,000 individuals and TMMC predicts there are now around 26,000 gray whales in the Pacific Ocean, which is about the number before the whaling boom got up steam almost 200 years ago.
Although the gray whale population has recovered to a certain degree, the number of dead whales washing up this year is alarming, Halaska said. Climate change and declining fish stocks are likely key factors in the whales’ poor health, she said .
Halaska stressed that boaters and beachgoers on the West Coast should watch out for gray whales this time of year.
1.What are the statistics in paragraph 3 about?
A.Severe conditions facing gray whales.
B.An agreement to stop killing whales.
C.The evolving development of gray whales.
D.The number of gray whales in different times.
2.What’s Halaska’s attitude towards the population of gray whale?

3.What may be talked about following the last paragraph?
A.The importance of gray whales.

A few years ago, I was on a plane with my friend, waiting for it to take off． The pilot’s voice was heard throughout the plane: “Sorry for the delay, ladies and gentlemen． Our engines don’t work． We are going to jump-start them． Once we get them going, we’ll get up in the air and see what happens．”
That was all he said． “See what happens?” Shouldn’t we have had a better plan than that? At that point． I could only laugh nervously． One woman started crying, “Oh no! We are going to crash!’’ There were sighs of hopelessness and anxiety, and we hadn’t even taken off yet．
The pilot even seemed unhappy． He told us our one engine was working double time, and his plan was to get up in the air and see what happens! Then we did． We got up in the air, and what happened? Nothing． We arrived in Norfolk, and no sooner had the wheels touched down than applause burst out as everyone on the airplane breathed a sigh of relief．
While I do prefer planning better than “see what happens” when it comes to flying, it really isn’t such a bad idea for life．All too often, people stop trying to achieve their goals just because they don’t have a guaranteed result． But success will never be guaranteed． The best thing that you can do is just get up in the air, and see what happens． If your effort is to build a business then get up in the air and see what happens! Don’t give yourself all the reasons why you can’t． Do not wait until you have everything you need． You never will!
If your goal is to start a friendship, say “Hello”, get up in the air and see what happens! The results could be very rewarding．
If your goal is to learn a new skill, get up in the air and see what happens! It might not be as difficult as your think． It could be fun!
When traveling, i hope that my pilot has a more detailed plan than “we will see what happens” ． But in life, it is not a bad strategy at all．
1.What was the pilot’s attitude toward the situation?
A．Disappointed and panicked
B．Surprised and honest
C．Comforting and encouraging
D．Hesitant and weak．
2.What was the passengers’ reaction when they arrived in Norfolk ?
A．They were thankful and relieved．
B．They cheered for the pilot’s correct operation．
C．They complained that the plane was not safe enough
D．They just walked off the plane as if nothing had happened．
3.What can we know from the passage?
A．The plane was delayed because of its wheels．
B．The plane arrived at the airport safely．
C．It was a terrible journey for the author．
D．Most of the passengers remained calm on hearing the bad news
4.What is the main idea of this article ?
A．“we will see what happens” is not a good plan for pilots
B．Try to have everything prepared before you do something
C．When you want to do something, you have to actually do it ．
D．Never stop chasing your goals even if they are certain to fail

A few years ago I was on a bicycle trip when I got off my bike for a rest. I sat down on the grass. A few seconds later, I was covered in ants. They were swarming all over me so I got up and brushed them off. It was a strange experience but I soon forgot about it.
A couple of years later, I was living in Jordan. I had just moved into a modern flat and was unpacking plates when I saw something move out of the corner of my eye. I looked over at the kitchen drawer and there was a cockroach (蟑螂) crawling out of it. I screamed. Then I grabbed a can of insecticide and sprayed it on the cockroach. He ran under the nearby bathroom door. It took me three days before I found the courage to open the bathroom door to see if he was still alive. He wasn’t.
Why did I react so violently to one lone insect when a closer encounter with hundreds of ants hardly affected me? The answer is easy: because cockroaches are creepy (令人毛骨悚然的) crawlies and ants aren’t. Creepy crawlies are those little bugs which cause feelings such as anxiety - they make your skin crawl.
Did you know that some people feel such a fear of bugs that it becomes a phobia (恐惧症)? Psychologists have offered many explanations. Some say we associate them with dirt and disease. Or that these are life forms that are so alien to us, that we find them disgusting for their dissimilarity.
Insects, however, don’t follow our rules - they just do what they want and invade our space. Unfortunately, although insects and bugs have been a successful animal species up to now, many of them, like many other species nowadays, are under threat of dying out. Entomologists warn that this could upset entire ecosystems and lead to all kinds of disastrous consequences.
So my advice to you is: the next time you feel the urge to stamp on, splatter or spray a creepy crawly, give a thought to the planet and stop.
1... Why did the author mention the ants in the beginning?
A. Because the experience with the ants presents a sharp contrast to that with the cockroach later.
B. Because the author wants to show her preference to the ants and her dislike for the cockroaches.
C. Because both ants and cockroaches are creepy crawlies that the author dislikes.
D. Because meeting the ants is an unusual experience that the author can hardly forget.
2.. The underlined word “insecticide” in Paragraph 2 probably means ________.
A. a kind of fruit juice B. a kitchen knife
C. liquid for killing insects D. cleanser (洗涤剂)for the bathroom
3.. How does the author feel about bugs like cockroaches?
A. The author doesn’t mind the contact with those harmless small creatures.
B. The author prefers cockroaches to ants and feels guilty for killing one.
C. They invade our space and become a threat to humans.
D. They still deserve a place for keeping the balance of the nature.
4.. Which of the following statements about bugs is NOT true according to the passage?
A. Some people may be frightened so much by bugs that it leads to a psychological barrier to some degree.
B. The earth will have a better and cleaner environment if more creepy crawlies are killed.
C. Many bugs are in danger of dying out so we should not kill them due to fear or disgust.
D. Some bugs are extremely unpleasant that some people have a strong wish to destroy them.

The researchers say a person loses two months for every kilogram overweight they are— and seven years for smoking a packet of cigarettes a day.
Unusually, the Edinburgh university team found their answers by analysing differences in people’s genetic code or DNA. Finally they think it will show new ways of helping us to live longer.
The group used the genetic code of more than 600, 000 people who are taking part in a natural experiment. If someone smokes, drinks, drops out of school and is overweight, it can be difficult to identify the impact of one specific unhealthy behavior.
Instead, the researchers turned to the natural experiment. Some people carry mutations(变异) in their DNA that increase(食欲) or make them more likely to put on weight, so researchers were able to compare those programmed to eat more with those who were not. The research team also found specific mutations in human DNA that alter lifespan (寿命).
●Mutations in a gene (a set of instructions in DNA) that is involved in running the immune system could add seven months of life on average.
●People with a mutation that increased levels of bad cholesterol knocked eight months off lifespan.
●A rare mutation in a gene—APOE—linked to dementia reduced lifespan by 11 months.
●And one that made smoking more appealing cut lives by five months.
Dr Joshi says that while genes do influence lifespan, “you’ve got even more influence” through the choices you make. Dr Joshi said, “We hope to discover genes affecting lifespan to give us new information about ageing and construct treatment tor ageing.”
There are also some disease mutations that clearly affect lifespan and to destructive effect, such as the Huntington’s gene. People with Huntington’s often die in their 20s.
However, in order to follow people until the end of their lives, many of the people studied were born before 1940.
1.What is the most difficult for the researchers to find?
A. The differences in people’s genetic code.
B. The reasons why people put on weight very easily.
C. The results of many natural and massive experiments.
D. One bad behaviour’s effect on people with many bad behaviours.
2.Which of the following mutations affects lifespan most greatly?
A. One linked to controlling immune system.
B. One increasing unhealthy cholesterol.
C. One called APOE involved in dementia.
D. One making smoking more attractive.
3.What’s the meaning of Dr Joshi’s study?
A. To help stop mutations. B. TO find diseases earlier.
C. TO make people live longer. D. TO reduce the effects of genes.
4.Why did researchers mainly study people born before 1940?
A. To follow them until they die. B. TO educate them an extra year.
C. To show they are more important. D. To make them live happier.

When I sent my daughter, Emma, off for her freshman year of college a few years ago, I found myself affected by an unbelievable feeling of melancholy. Clearly, I'm not alone. Just last week, The Wall Street Journal reported that more than 90 percent of colleges offer to help moms and dads who are “struggling with the change.”
Between Thanksgiving, winter holiday, spring break and summer break, the first one out of my nest has come fluttering back home nearly every month of the year since she has been away. Good friends like to joke that they see more of her now than they did when she was a senior in high school. In the meantime, Emma calls, texts or e-mails me almost every day.
Given all this, missing Emma seems kind of silly；I've never really gotten the chance. So why, then, have I still felt on some level that I've experienced a great loss?
All summer long before Emma left that first year, I took Emma out for countless mother-daughter breakfasts, lunches, coffees and walks. At the same time, I seemed to find fault with Emma all the time. In my eyes, Emma had spent the weeks leading up to school going out with her friends too much, staying out way too late, making too big a mess, not working enough and, for goodness sake, certainly not spending enough time with me!
Although it's taken quite a while to realize what was happening, I now understand that my unhappiness and anxiety are not a reflection of how much time Emma and I spend together. Regardless of how often she comes home, or how many times a day we chat or text, Emma is now gone in a far grander sense. She is well on the road to adulthood, and from this, she will never return.
1.What does the underlined word “melancholy” in paragraph 1 refer to?
A.Fierce anger. B.Deep sadness.
C.Extreme excitement. D.Great satisfaction.
2.Why does it seem silly for the author to miss her daughter?
A.They keep in touch frequently. B.Friends like to make fun of her.
C.Emma has grown up to an adult. D.Other parents don't behave like this.
3.What actually made the author overly worried?
A.The untidiness of Emma's room. B.The passing of Emma's childhood.
C.Taking Emma out all too often. D.Spending little time with Emma.
4.What is the best title for the text?
A.Changes in the Parent-Child Relationship B.The Most Concerned Parents of All Time
C.Growing Pains for College Students D.Struggling to Let Go of My Daughter
