(10 points) My husband, Tom, has always been good with animals, but I was still amazed when he befriended a female grouse (松鸡). It’s 1 for a grouse to have any contact (接触)with people. In fact, they’re hard to spot, 2 they usually fly off when they hear humans approachingThis grouse came into our lives in 3 Tom was working out in the field when he 4 her walking around at the edge of the field. She was 5 unafraid and seemed to be 6 about what he was doing,Tom saw the 7 bird several times, and site got more comfortable around him. We quickly grew 8 of the bird and decided to call her Mildred.One day, as Tom was working, Mildred came within a few feet of him to watch. Tom 9 he didn’t see her and kept working to see what she would do next.Apparently, she didn’t like to be 10 . She’d run up and peck (啄) at Tom’s hands, then 11 off to see what he would do. This went on for about 20 minutes, until Mildred became tired of the 12 and left.As spring went and summer came, Mildred started to 13 more and more often. 14 Mildred felt comfortable enough to jump up on Tom’s leg and stay long enough for me to get a 15 of the two of them together. This friendly grouse soon felt 16 no just with our family, but with anybody who walked or drove by.When hunting season opened, we put a 17 at the end of our driveway asking 18 not to shoot our pet grouse. My father, who lived down the road, 19 warned people not to shoot her. 20 , hunters would stop and take pictures, because they had never seen anything like her.1、A．interesting B．reasonable C．impossible D．unusual2、A．though B．because C．unless D．until3、A．spring B．summer C．autumn D．winter4、A．got B．kept C．noticed D．imagined5、A．naturally B．certainly C．normally D．surprisingly6、A．crazy B．curious C．concerned D．cautious7、A．shy B．awkward C．friendly D．elegant8、A．careful B．tired C．fond D．sick9、A．supposed B．realized C．hoped D．pretended10、A．ignored B．observed C．amazed D．disturbed11、A．put B．back C．set D．take12、A．game B．work C．place D．man13、A．give up B．come out C．turn over D．fly by14、A．Eventually B．Suddenly C．Constantly D．Presently15、A．chance B．dream C．picture D．sense16、A．comfortable B．guilty C．anxious D．familiar17、A．lantern B．sign C．gun D．loudspeaker18、A．drivers B．farmers C．hunters D．tourists19、A．just B．yet C．thus D．also20、A．In fact B．For long C．On the contrary D．By the waySection II Reading ComprehensionPart ADirections:Read the following four texts.

Scientists behind a new study have worked out how to identify individuals only based on the proteins(蛋白质) in a single strand of their hair.While the police already look at DNA from hair as part of investigations, the technique is far from ideal: DNA is easily degradable, meaning it can only be analyzed within a certain time period after the crime. But the new technique could even be used to solve historical or archaeological cases, making it far superior to DNA sequencing in many ways.DNA degradation depends on several environmental factors including temperature, humidity and PH. It is also affected by the activity of bacteria and other microorganisms. In contrast, actual hairs can survive for a long time-----sometimes centuries. After bones and teeth, hair is in fact one of the most resistant structures of the human body.In order to understand how the protein can be used to identify individuals, it is important to understand mat proteins are coded by DNA．This means that a certain level of the genetic variation that we see in different people's DNA passes into their proteins. In fact, genetic information in the DNA is translated into amino-acid chains that make up proteins.The method not only allows for human identification but it can also reveal how old the sample is and what region it comes from, so that we can distinguish between current and ancient samples. But while the discovery is exciting, the technique is not quite polished enough to be used in the court room. The main task now will be to analyze hair samples from all over the world, which will make it a lot more reliable.The new discovery will boost the significance of hair as evidence in courts, at a time when some forensic(司法鉴定的) disciplines have been criticized in the US. It will also be of great use in archaeology.1、What's the main idea of the passage?A．DNA evidence is far from ideal.B．Criminals on the run get hair-raising news.C．Scientists are planning a test of human hair.D．Humans can be identified by proteins in hair.2、Which evidence is more reliabl。
