-I        some food．（　�。�
A．did； do； makeB．are； doing；made
C．were； doing； was makingD．were； doing； made

分析 -昨天九點(diǎn)鐘你正在做什么？
-我正在做飯．

解答 答案：C
根據(jù)時(shí)間狀語(yǔ) at 9：00yesterday，可知應(yīng)該用過(guò)去進(jìn)行時(shí)態(tài)，表示在過(guò)去某一時(shí)刻或某一段時(shí)間內(nèi)進(jìn)行或發(fā)生的動(dòng)作用過(guò)去進(jìn)行時(shí)，過(guò)去進(jìn)行時(shí)的構(gòu)成是was/were+現(xiàn)在分詞，根據(jù)句意：-昨天九點(diǎn)鐘你正在做什么？-我正在做飯．故選C．

點(diǎn)評(píng) 本題主要考查過(guò)去進(jìn)行時(shí)，做此類(lèi)題目，可以根據(jù)時(shí)間狀語(yǔ)，也可以根據(jù)上下文語(yǔ)境，進(jìn)行判斷．

7．Harmful microbes like bacteris，viruses and other germs are pathogens．They may enter your bodies and make you ill．The immune system is the body's defence system that protects you from illness and disease caused by the pathogens．
The immune system is made up of non-specialized defences such as skin，tears and the acidic juice produced by the stomach，keeping you from the pathogens．It also has some highly specializde defences，which are different kinds of immune cells，grouped into phagocytes and lymphocytes．Phagocytes are a type of white blood cell．They are swimming around in your blood stream，always on the lookout for antigens-the pathogens that have entered your bodies．Whenever they see one，ther will eat it．However，some antigens are hard to find and kill．Then lymphocytes，which are also white blood cells and the main types are B cells，T helper cells and T killer cells，Will be the killers of the sncaky antigens．
B cells，T helper and T killer cells work together to find and kill these antigens．B cells produce substances，called antibodies，which stick to the antigen．When that happens，it will tell the T helper cells to come over and either：1．help the B cells kill the antigen，or 2．call the phagocytes or T killer cells to move in for the kill．Once a B cell or a T cell attacks an antigen，they create cells to"remember"it．Those"memory cells"hang out in your blood if they see the same antigen again，they quickly recognize，it so your immune system can act faster at killing it．
The immune system is more powerful than you probably imagine．Scientists from the University of Pennsylvania recently took immune cells from three patients with leukemia，then genetically cheanged them into"serial Keller"cells to attack cancer cells．The study was small but the results were groundbraking．The modified immune cells increascd at least 1，000 times in the body and killed all the cancer cells．Therefore，more"memory cells"were created．
  The immune system can be developed．Eating lean protein food （beef，beans ）and food rich in vitamins A，C，and E（sweet potatoes，carrots ），taking a 30-minute walk every day and reducing your stress levels，etc．will help you achieve it．

37．What can the immune system do？B
A．Keep you from antibodies．
B．Protect you against antigens．
C．Make your bodies werk and sick．
D．Help microbes enter your bodies
38．How are the sneaky antigens found and killed？A
A．Phagocytes，B，T helper and T killer cells work together
B．Skin，tears，acidic juice and immune cells work together
C．B cells create"memory cells"to swim around in the blood
D．B cells produce antibodies to tell T helper and T killer cells
39．What does the underlined word"it"in the last paragraph refer to？A
A．The immune system can be made more powerful
B．Less antigens can be killed by the immune system
C．White blood cells act less quickly in the immune system
D．The immune system can be changed into the"serial killer"
40．This article is mainly aboutD．
A．the types of white blood cells
B．a(chǎn) research report about human healeh
C．the cause of illness and discase
D．a(chǎn)n introduction to the immune system．

11．
 Food
It's Mango Time!
--How much do you know about one of the world's most popular fruits？
Some people call mangoes the"king of fruit，"while others just call them delicious!Those who love mangoes anxiously wait for the first ripe ones of the season．And not only do mangoes taste great but they also are good for you!
Did you know…
-People think mangoes were first planted over 5，000years ago in India．
-The countries of India and the Philippines have announced mango their national fruit．
-A mango tree can live up to 300years．
-Countries that are major mango producers
include Mexico，Egypt，Pakistan，Brazil，Indonesia，Australia and Israel．
-A cup of the fruit has only 100Calories and is nearly fat-free．
-Mangoes are a vital food source for millions of people．
-One cup of mango contains 100percent of the daily requirement for vitamin C．
-Mangoes contain over 20vitamins and minerals，making them a"superfood．"
-The fruit can be eaten raw，cooked，dried or canned．
So treat yourself to a mango today!		Health
A good night's sleep
Do you get the sleep you need？
When the morning sun looks in through our window，do you jump out of bed or go on lying？
Having enough sleep can make the difference between a great day and a terrible one!
Here are the tips for a good night's sleep：
First，go to bed and get up at the same time，even if you haven't gotten a good night's sleep．
Sleeping late for just a few days can change your body clock to a different cycle．
Also，avoid big meals at night．Eating heavy rich food within two hours of bedtime can keep you awake，Your stomach works hard because of those fatty foods，and that may keep you up．Your body
produces a chemical called melatonin that helps you sleep．Light changes the amount of melatonin．It produces more in the evening and less in the daytime．So at night turn off your TV and PC．Also，don't read from abacklit device（有背光的設(shè)備） like an iPad．Some scientists think that the light from those devices stops your body from making melatonin．So turn those screens off at least an hour before bedtime．
After a good night's sleep，you'll be able to face a new day．
31．According to the passage，we can learn thatD．
A．Australians consider mango as the national fruit
B．mangoes are rich in fat to meet people's daily need
C．there are all kinds of vitamins and minerals in mangoes
D．People enjoy mangoes because they are healthy and tasty
32．According to the second passage，we can make our body produce more melatonin byC
A．surfing the Internet on the computer or iPad
B．changing our body clocks to different cycles
C．turning off TVs at least an hour before sleeping
D．enjoying some outdoor activities in the open air
33．These two articles may come fromB．
A．a(chǎn) story book
