Now this is something that has been researched and they are definitely genetic conditions that are associated with autism. Something like (2) __________________X. And that is a testing that is done in children often diagnosed with autism. It is rare but there's an abnormality in the (3) ____________________being transmitted. That is an issue in some children, however, this is a very small (4) ___________________of children who get diagnosed with autism who actually have a fragile X problem. There are other medical conditions which are genetically known but the understanding is that it is not one gene, but there are (5) _______________ genes and it's probably a host of little differences whether you call them denovo (6) _________________or changes that take place, or single nucleotide polymorphisms called snips, which can contribute and work together as a (7) ______________to cause a difference in the immune system, in themethylation cycles and in so many other areas that are important in the neurochemistry and the neurobiology of the brain.

【填空题】Lesson 5 听力填空-3 Departure Control Listen to the recording and fill in the blanks with what you have heard After the local controller has guided airplane through the take-off phase, the pilot will be instructed to change 1 and contact the departure controller. Departure controllers work at the terminal radar approach facility and they direct the airplane from the 2 to the center’s airspace. The departure controllers monitor the airplanes which are identified by their tags on the 3 . The tag provides controllers with much information such as 4 , aircraft type, airspeed and altitude. Controllers rely on this information to keep all departing aircraft at 5 with each other. In order to maintain 6 among departing aircraft, departure controllers might also direct the pilot to turn the airplane to different course heading or have the aircraft 7 or to have it fly faster or slower. When the departure controllers guide each aircraft through 8 and when the aircraft has reached the 9 transferring altitude, they will perform 10 of the flight to the center controller. They will monitor the flight until it reaches the edge of the radar screen.
